Description

[0001] Installation system for an elevator system

[0002] The invention relates to an installation system for an elevator system according to the preamble of claim 1.

[0003] EP 2935075 Bl describes an installation system for an elevator system comprising a carriage for accommodating installation materials, a controllable winch for vertically moving the carriage within the elevator shaft, a main control unit for activating and stopping the winch, a lower position detection system for recognizing the carriage's lower target position, and an upper position detection system for recognizing the carriage's upper target position. The carriage is designed as a counterweight frame for the elevator system, which is guided by counterweight guide rails already installed in the elevator shaft. Installation materials in the form of elevator components, such as counterweight guide rails, car guide rails, shaft doors or shaft door components, fasteners, traction elements, drive components, etc., can be carried on the counterweight frame.They are transported or moved vertically within the elevator shaft. The aforementioned position detection systems include limit switches, which are activated by the counterweight frame when the corresponding target position is reached, at which point the winch is stopped.

[0004] In contrast, the object of the invention is, in particular, to propose a configurable installation system for an elevator system that is especially easy to install. According to the invention, this object is achieved with an installation system having the features of claim 1.

[0005] The installation system according to the invention for an elevator system comprises a carriage for accommodating installation materials, a controllable winch for vertically moving the carriage in an elevator shaft, a main control unit for activating the winch upwards and downwards and for stopping the winch, a lower position detection system for detecting a lower target position of the carriage, and an upper position detection system for detecting an upper target position of the carriage. The main control unit is designed and configured such that, upon receiving a downward target movement instruction, it activates the winch downwards until it receives a signal indicating that the carriage has reached the lower target position, and upon receiving an upward target movement instruction, it activates the winch upwards until it receives a signal indicating that the carriage has reached the upper target position.

[0006] According to the invention, the installation system also has a lower control unit and an upper control unit, wherein

[0007] - a signal connection exists between the lower control unit and the lower position detection system, so that the lower control unit can detect when the vehicle has reached the lower target position,

[0008] - a signal connection exists between one of the lower control units and the upper control unit and the upper position detection system, so that the reaching of the upper target position by the vehicle body is detectable by the control unit in signal connection with the upper position detection system,

[0009] - a signal connection exists between the lower control unit and the main control unit, and between the upper control unit and the main control unit,

[0010] - the lower control unit is configured to transmit a signal to the main control unit indicating that the vehicle has reached the lower target position,

[0011] - the control unit, which is in signal communication with the upper position detection system, is configured to transmit a signal to the main control indicating that the vehicle has reached the upper target position and

[0012] - at least one of the lower control unit and the upper control unit is designed and configured in such a way that the target driving instruction for the vehicle downwards to the lower target position and the target driving instruction for the vehicle upwards to the upper target position can be entered and the said target driving instruction is transmitted to the main control unit.

[0013] The lower and upper control units can be reconfigured, connected to one or both position detection systems, and equipped with input options for destination driving instructions and other input options for an installer. This allows the installation system to be configured and adapted to various requirements and applications. Regardless of the configuration of the aforementioned control units, only one signal connection is required between each control unit and the main controller, which simplifies installation of the system. The described operation of the installation device, in which the moving body is automatically moved to the respective target position after a destination driving instruction is entered, is referred to as automatic operation.

[0014] The carriage of the installation system can be designed in various ways. It simply needs to be designed to accommodate installation components, such as counterweight guide rails, car guide rails, rail brackets for fixing guide rails to a shaft wall, shaft doors or components of shaft doors, fasteners, traction elements, or drive components. "Accommodation" in this context means that the installation components can be stored in a designated space within the carriage, attached to the carriage, or otherwise secured to the carriage in such a way that they move along with the carriage when it is repositioned within the elevator shaft. The carriage can be designed, for example, as a frame made of metal profiles or simply as a beam.It is also conceivable that the vehicle body is designed as a cabin – especially a temporary one – which can be used to transport not only installation materials but also people.

[0015] The carriage is guided, particularly during relocation within the elevator shaft. This guidance can be achieved, for example, along existing counterweight or car guide rails, or along a shaft wall. The carriage can be equipped with appropriate guide elements, such as guide shoes or guide rollers. The carriage can also be moved within the elevator shaft without any guidance.

[0016] In this context, a controllable winch is understood to be a winch, for example a cable-driven winch, with a drive, in particular an electric motor, by means of which a lifting element, especially in the form of a cable, can be moved. The lifting element is connected to, or connectable to, the vehicle body; for example, the vehicle body is attached to a hook fixed to the lifting element, so that the vehicle body can be moved together with the lifting element.

[0017] The main winch control unit can directly control the winch drive, for example, supplying energy to the electric motor or stopping the energy supply. However, it is also possible that a separate winch control unit is present to control the electric motor, receiving commands from the main control unit and translating these commands into corresponding commands for the winch drive.

[0018] Both position detection systems each feature a sensor that communicates with one of the aforementioned control units. The sensor can, for example, be a switch that changes its state when the vehicle reaches the corresponding target position. Alternatively, the sensor could be a Hall effect sensor, a proximity switch, or a photoelectric sensor. The sensor simply needs to be capable of detecting when the vehicle reaches the target position.

[0019] The lower target position is located, in particular, at the level of a so-called delivery level. The installation materials are delivered to the delivery level and can be brought into the elevator shaft via a shaft opening. The upper target position is located, in particular, at the level of an installation platform where the installation materials are needed and from which they are installed in the elevator shaft. The installation platform is located above the delivery level and can, for example, be the roof of the elevator car, the roof of a temporary car, or another type of installation platform. When repositioned within the elevator shaft, the installation platform can, for example, be guided by already installed car guide rails.

[0020] The lower and upper control units are specifically configurable and programmable. They each feature a programmable microcontroller. The terms "lower" and "upper" control unit serve only to distinguish between the two units and do not necessarily indicate their physical location within the elevator shaft. One control unit may be a mobile device, such as a mobile phone. The lower and upper control units can be identical or different.

[0021] The signal connections between the two position detection systems and the corresponding control unit are primarily wired. However, a wireless signal connection is also possible. At least one of the two control units has input options, such as buttons, pushbuttons, or rotary switches. These input options can also be implemented electronically, for example, via a touch-sensitive display. Using these input options, an installer can, for example, enter target or travel instructions for moving upwards or downwards, which are then transmitted to the main control unit and executed by it.

[0022] In a typical application of the installation system, installation materials, such as counterweights and car guide rails, are delivered to a delivery level and carried into the elevator shaft by a first installer via a shaft opening. These materials are then installed in or on the car. The car is not held by the winch, but rather by a holding device. This holding device can, for example, be a brake mounted on the car and acting on a guide rail. If the car is not held by the winch, the winch can be used to load the car. The brake can be operated manually by an installer or controlled, for example, by a main control system.

[0023] Once the loading platform is fully loaded, the first installer reconnects it to the winch and deactivates the holding device. The first installer, or a second installer located on the installation platform, then enters a target command for upward movement via an input device on a control unit. The control unit transmits this command to the main control system, which then activates the winch. Activating the winch means that it is controlled in such a way that its lifting mechanism and the attached loading platform are moved upwards.

[0024] The activation is maintained until the upper position detection system recognizes that the transport unit has reached the upper target position on the installation platform and this is transmitted to the main control unit via a control unit. The main control unit then stops the winch. Subsequently, the holding device is reactivated and the transport unit is disconnected from the winch, allowing the second installer to unload the guide rails from the transport unit using the winch. After unloading, the second installer can reconnect the transport unit to the winch, deactivate the holding device, and enter a downward target movement instruction at a control unit. After the downward target movement instruction is transmitted to the main control unit, it activates the winch downward until the transport unit reaches the lower target position. The described procedure can then be repeated.Activating the winch downwards means that the winch is controlled in such a way that its lifting mechanism and an associated vehicle body move downwards.

[0025] In this embodiment of the invention, the signal connections between the lower control unit and the main control unit, as well as between the upper control unit and the main control unit, are wireless. This eliminates the need to run cables through the entire elevator shaft; instead, only relatively short cables are required from a control unit to a position detection system. The installation effort for the system is therefore very low. Furthermore, there is no risk of cables being damaged during operation or of an installer becoming entangled in a cable and injuring themselves. The aforementioned wireless signal connection can be implemented, for example, as a Bluetooth, WLAN, Zigbee, or Z-Wave connection. The signal connections between the control units and the position detection systems are, in particular, wired.It is also possible that a wired signal connection is used instead of the aforementioned wireless signal connection.

[0026] In this embodiment of the invention, the main control unit is designed and configured to stop the winch in response to an interruption of the signal connection to at least one of the lower control units and the upper control unit. This enables particularly safe operation of the installation system. The main control unit is configured and programmed to continuously check whether the signal connections to the control units are active. The main control unit can thus detect such an interruption of the signal connection. The control units can, for example, send messages, particularly changing ones, to the main control unit at regular intervals. As soon as the main control unit no longer receives these messages, it detects an interruption of the corresponding signal connection and stops the winch.Detection of an interruption in the aforementioned signal connections can also be carried out in another manner known to those skilled in the art. In an embodiment of the invention, at least one of the lower control units and the upper control unit is designed and configured such that a manual travel instruction for the transport unit downwards and a manual travel instruction for the transport unit upwards can be entered, and these manual travel instructions are transmitted to the main control unit. The main control unit is designed and configured such that, as long as it receives a manual travel instruction downwards, it activates the winch downwards, and as long as it receives a manual travel instruction upwards, it activates the winch upwards. The transport unit is thus only moved in the desired direction as long as an installer enters the manual travel instruction via an input option on a control unit, for example, by pressing a button on a control unit.This mode of operation of the installation system is referred to as manual operation. In manual operation, it is possible, in particular, to move the transport body beyond the specified target positions. Specifically, end positions are defined which cannot be exceeded even in manual operation. These end positions can be set, for example, using spindle limit switches directly on the winch.

[0027] In one embodiment of the invention, the installation system has a warning device that issues a warning when a destination travel instruction is executed. This enables particularly safe operation of the installation system. A technician located in the elevator shaft is warned when a destination travel instruction is executed, i.e., when the car automatically moves within the elevator shaft, thus reducing the risk of injury to the technician caused by the car. The warning device can be, for example, a loudspeaker emitting a signal tone, a warning light, or a combination of both. The warning device can be located, for example, on the car or at the main control unit. It is also possible for the installation system to have two warning devices, with one located at the upper destination position and the other at the lower destination position.The warning device is primarily controlled by the main control unit. The necessary signal connection can be wireless or wired. The warning device can also issue a warning when a manual driving instruction is executed.

[0028] In an embodiment of the invention, at least one of the lower control units and the upper control unit are designed and configured such that a stop command for the drive unit can be entered and the said stop command is transmitted to the main control unit. The main control unit is designed and configured such that it stops the winch in response to receiving the stop command. This enables particularly safe operation of the installation system. The stop command can also be referred to as an emergency stop. The input of a stop command is achieved, in particular, via a

[0029] Input option on a control unit. If the winch is stopped when the stop command is entered, this state remains.

[0030] The ability to input a stop command is particularly advantageous in the automatic operation of the installation system. If an installer detects a potential hazard or problem, they can stop the moving unit by entering a stop command. After a stop command has been entered, a special reactivation of the automatic operation may be necessary. For this purpose, a control unit may have a dedicated input option, such as a push button. Alternatively, a specific sequence of inputs at the control unit may be required, for example, a target travel instruction upwards, then downwards, and then upwards again within 5 seconds.

[0031] The ability to input a stop command is also advantageous in manual operation of the installation system. If a first installer enters a manual travel command via a control unit, thereby moving the elevator car in the shaft, and a second installer recognizes a potential hazard or problem, the second installer can stop the elevator car by entering a stop command.

[0032] In this embodiment of the invention, the installation system includes a rail end detection sensor that communicates with one of the lower and one of the upper control units. The rail end detection sensor detects when the carriage reaches the end of a guide rail that carries it within the elevator shaft. The main control unit is then designed and configured to stop the winch upon receiving a signal indicating that the end of the guide rail has been reached. This advantageously prevents the carriage from being moved beyond the end of the guide rail and thus from moving unguided within the elevator shaft, which could lead to damage to the carriage and the elevator shaft.

[0033] The rail end detection sensor can be permanently located at the end of the guide rail, particularly the already installed counterweight guide rail, and can be actuated, for example, by a guide roller mounted on the carriage and rolling along the guide rail when the carriage reaches the rail end. The rail end detection sensor can also be permanently mounted on the carriage and actuated even if no guide roller is rolling along the guide rail. The control unit connected to the rail end detection sensor is designed and configured to transmit a corresponding signal to the main control unit when the rail end detection sensor detects that the carriage has reached the rail end, which then stops the winch.

[0034] In this embodiment of the invention, the position detection systems each comprise a first component fixed in the elevator shaft and a second component mounted on the elevator car. This allows for a particularly simple and reliable design of the position detection systems. One of the components is a sensor as described above, and the other component is a marker that can be detected by the sensor. These markers can be special elements, such as a projection, a nose, a protrusion, or a magnet. Alternatively, an existing element, such as the upper or lower edge of the elevator car, can serve as the marker. It is also possible for the markers of both the upper and lower position detection systems to be formed by a single marker.

[0035] In this embodiment of the invention, the first components of the position detection systems, which are fixed in the elevator shaft, are designed as sensors, and the second components, which are arranged on the elevator car, are designed as markers detectable by these sensors. The elevator car thus does not need to have any components requiring an electrical power supply. It is therefore unnecessary to install an energy storage device, for example in the form of a battery, on the elevator car or to supply the elevator car with electrical power via a cable. This enables particularly safe operation and particularly simple installation of the system. In this embodiment of the invention, a signal connection exists between the lower control unit and the sensor of the lower position detection system, and between the upper control unit and the sensor of the upper position detection system. This signal connection is preferably wired.This allows the necessary energy supply for the sensors, which are permanently located in the elevator shaft, to be provided by the respective control unit, enabling a particularly simple and safe energy supply for the sensors.

[0036] In this embodiment of the invention, the lower control unit is arranged at a delivery level and the upper control unit is arranged on an installation platform located above the delivery level. This advantageously places the control units near the position detection systems to which they are connected. This allows for a simple and cost-effective implementation of the aforementioned signal connections. Furthermore, when using the installation system as described above, there is an installer at both the delivery level and the installation platform who can operate the control units, for example, by entering driving instructions.

[0037] In one embodiment of the invention, the lower and upper control units are connected to a power grid. This eliminates the need for electrical energy storage devices, such as batteries, resulting in particularly reliable operation of the installation system. The sensors connected to the control units are thus also supplied with electrical energy via the power grid. Here, "connection to a power grid" means that the control units are supplied with electrical energy from a central power supply, such as a public power grid or a generator-powered power grid for the construction site where the installation system is operated.

[0038] In this embodiment of the invention, the second components of the position detection systems, arranged on the elevator car, are configured as sensors, and the first components, fixed in the elevator shaft, are configured as markers detectable by said sensors. It is possible for the sensors of the lower and upper position detection systems to be combined into a single sensor. In particular, a signal connection exists between the lower control unit and the sensor of the lower position detection system, and between the lower control unit and the sensor of the upper position detection system. The sensors of both position detection systems are thus connected to the same control unit, which minimizes installation effort.

[0039] In one embodiment of the invention, the lower control unit is arranged on the vehicle body and the upper control unit on the installation platform. Advantageously, the upper control unit can be operated by an installer. The lower control unit and the sensors on the vehicle body are supplied with electrical energy, for example, by an electrical energy storage device, such as a battery. This eliminates the need for a cable, such as a suspension cable, to the vehicle body. The upper control unit can be supplied with electrical energy from a power grid or from an electrical energy storage device.

[0040] In this embodiment of the invention, the installation system has a third control unit located at the delivery level and connected to the main control unit via a signal. This control unit is designed and configured to allow the input of a driving instruction for the transport unit, which is then transmitted to the main control unit. This provides the installer with a control unit at the delivery level for inputting driving instructions. In particular, the third control unit offers input options for driving instructions and a stop instruction, analogous to the other two control units.

[0041] This installation system is particularly advantageous when installing an elevator. However, it can also be used for moving materials and / or people for other purposes.

[0042] Further advantages, features, and details of the invention will become apparent from the following description of exemplary embodiments and from the drawings, in which identical or functionally equivalent elements are provided with identical reference numerals. The drawings are schematic only and not to scale.

[0043] This shows:

[0044] Fig. 1 shows an elevator shaft with an installation system during the installation of an elevator system and

[0045] Fig. 2 shows an elevator shaft with an alternative installation system. According to Fig. 1, an installation system 12 is arranged in an elevator shaft 10 during the installation of an elevator system. This system allows installation materials, for example, guide rails or guide rail sections 14, to be moved vertically within the elevator shaft 10. The guide rail sections 14 can thus be transported vertically upwards from a delivery level 16, where they are delivered to the elevator shaft 10, to an installation platform 18 within the elevator shaft 10. The installation platform 18 is formed by the roof of a temporary cabin 20, which is used during the installation of the elevator system and removed from the elevator shaft 10 before the installation is completed.The installation platform can also be designed, for example, as the roof of the final cabin of the elevator system or as another type of installation platform.

[0046] The installation system 12 has a controllable winch 24 fixed to a shaft ceiling 22 of the elevator shaft 10. The winch has an electric motor 26 and a suspension element in the form of a cable 28. The cable 28 can be moved up and down by the electric motor 26. The winch 24 is controlled by a main control unit 30, which can activate and stop the winch 24 in both directions. When the winch 24 is activated in the up or down direction, the electric motor 26 is controlled by the main control unit 30 such that the cable 28 is moved up or down, respectively. The cable 28 of the winch 24 is connected to a carriage 32 of the installation system 12, so that when the cable 28 is moved, the carriage 32 is also moved vertically in the elevator shaft 10. The carriage 32 is designed as a cuboid element made of metal profiles. The chassis can also be designed as a frame or as a beam.During relocation, the carriage 32 is guided along already installed counterweight guide rails 34 in the elevator shaft 10. The carriage 32 has guide elements (not shown), such as guide shoes or guide rollers. A holding device in the form of a brake 36, acting on the counterweight guide rails 34, is located at the bottom of the carriage 32. The brake 36, which can be operated manually, for example, allows the carriage 32 to be held at a predetermined position in the elevator shaft 10 even without assistance from the winch 24.

[0047] The installation system 12 has a lower position detection system 38, which includes a lower sensor 40 fixed in the elevator shaft 10 and a lower marker 42 located on the carriage 32. The lower sensor 40 is, for example, designed as a switch, which is actuated by the lower marker 42, designed as a lug, when the carriage 32 assumes or reaches a lower target position. The installation system 12 also has an upper position detection system 44, which includes an upper sensor 46 fixed in the elevator shaft 10 and an upper marker 48 located on the carriage 32. The upper sensor 46 can, for example, be located on the temporary cabin 20. Since the temporary cabin 20 remains in one location during the use of the installation system 12, the upper sensor 46 is fixed in the elevator shaft 10.The upper sensor 46, for example, is also designed as a switch, which is actuated by the upper marker 48, designed as a nose, when the vehicle body 32 assumes or reaches an upper target position. The aforementioned sensors and marker can also be designed in other ways.

[0048] The lower sensor 40, and thus the lower position detection system 38, is connected via a lower cable connection 50 to a lower control unit 52 located on the lower delivery level 16. This allows the lower control unit 52 to detect when the transport body 32 has reached the lower target position. The upper sensor 46, and thus the upper position detection system 44, is connected via an upper cable connection 54 to an upper control unit 56 located on the installation platform 18. This allows the upper control unit 56 to detect when the transport body 32 has reached the upper target position. When the lower control unit 52 detects, with the aid of the lower sensor 40, that the transport body 32 has reached the lower target position, it transmits a signal to the main control unit 30 indicating that the transport body 32 has reached the lower target position.When the upper control unit 56 detects, with the aid of the upper sensor 46, that the drive unit 32 has reached the upper target position, it transmits a signal to the main control unit 30 indicating that the drive unit 32 has reached the upper target position.

[0049] The lower control unit 52 and the upper control unit 56 are each connected to a power supply 58, which provides them and the connected sensors 40, 46 with electrical energy. The lower control unit 52 and the upper control unit 56 are also each wirelessly connected to the main control unit 30. This wireless signal connection can be, for example, Bluetooth, WLAN, Zigbee, or Z-Wave. Both the lower control unit 52 and the upper control unit 56 have input options 60, which can be implemented, for example, as switches, pushbuttons, or similar devices. The respective inputs via the input options 60 are transmitted by the control units 52, 56 to the main control unit 30 via the wireless signal connection and processed or converted by the main control unit 30.

[0050] The upper control unit 56 has an input option, specifically a rotary switch, for selecting either automatic or manual operation of the installation system 12. Furthermore, the upper control unit has an input option, specifically a push button or switch, for a stop command. Entering a stop command immediately stops the winch 24. Additionally, the upper control unit 56 has two input options, specifically push buttons, for entering a travel command upwards or downwards.

[0051] The lower control unit 52 has, in particular, the same input options as the upper control unit 56. In the event of conflicting inputs at the two control units 52 and 56, the inputs at the upper control unit 56 take priority over the inputs at the lower control unit 52. It is also possible that the lower control unit has fewer input options than the upper control unit. For example, the lower control unit may not have an input option for selecting between manual and automatic operation.

[0052] In manual operation of the installation system 12, the input of a downward or upward travel instruction is considered a manual travel instruction for the travel body 32. The main control unit 30 is designed and configured such that, as long as it receives a manual downward travel instruction, it activates the winch 24 downwards, and as long as it receives a manual upward travel instruction, it activates the winch 24 upwards.

[0053] In automatic operation of the installation system 12, the input of a downward or upward travel instruction is considered a target travel instruction for the transport body 32. The main control unit 30 is designed and configured such that, upon receiving a downward target travel instruction, it activates the winch 24 downwards until it receives a signal indicating that the transport body 32 has reached one of the lower target positions, and upon receiving an upward target travel instruction, it activates the winch 24 upwards until it receives a signal indicating that the transport body 32 has reached one of the upper target positions.

[0054] A warning device 62 is arranged on the shaft ceiling 22 near the main control unit 30 and is controlled by the main control unit 30. The warning device 62 is designed, for example, as a loudspeaker that emits a signal tone, as a warning light, or as a combination of loudspeaker and warning light. The warning device 62 is activated by the main control unit 30 when, in automatic operation of the installation system 12, the carriage 32 is automatically moved until it reaches a target position. When activated, the warning device 62 issues a warning.

[0055] The main control unit 30 is designed and configured to stop the winch 24 in response to an interruption of the signal connection to the lower control unit 52 and / or the upper control unit 56. The main control unit is configured and programmed to continuously check whether the signal connections to the control units 52 and 56 are active. The control units 52 and 56 can, for example, send messages, particularly changing ones, to the main control unit 30 at regular intervals. As soon as the main control unit 30 no longer receives these messages, it detects an interruption of the corresponding signal connection and stops the winch 24.

[0056] A rail end detection sensor 70 is arranged at the upper end of the already installed counterweight guide rail 34. The rail end detection sensor 70 is actuated by a guide roller (not shown) of the carriage 32 when the carriage reaches the end of the counterweight guide rail 34. The rail end detection sensor 70 is connected to the upper control unit 56, which sends a corresponding signal to the main control unit 30 when the rail end detection sensor 70 is actuated. In response to receiving this signal, the main control unit 30 stops the winch 24.

[0057] When using the installation system 12, guide rail sections 14 are delivered to the delivery level 16 and brought into the elevator shaft 10 by a first installer 64 via a shaft opening (not shown) and arranged in the carriage 32. The carriage 32 is held not by the winch 24, but by the holding device 36, which is manually activated, for example, by the first installer 64, before the carriage 32 is loaded. This allows the first installer 64 to use the winch 24 to load the carriage 32.

[0058] Once the loading platform 32 is fully loaded, the first installer 64 reconnects it to the winch 24 and deactivates the holding device 36. The first installer 64, or a second installer 66 located on the installation platform 18, then enters a target travel instruction upwards via input 60 on the lower control unit 52 or the upper control unit 56. The control unit transmits the target travel instruction to the main control unit 30, which then activates the winch 24 upwards. This activation is maintained until the upper position detection system 44 detects that the loading platform 32 has reached the upper target position at the installation platform 18, and this is transmitted from the upper control unit 56 to the main control unit 30 as described. The main control unit 30 then stops the winch 24.The second installer 66 then activates the holding device 36 and disconnects the transport unit from the winch 24. The second installer 66 can then unload the guide rail sections 14 from the transport unit 32 using the winch 24. After unloading, the second installer 66 can reconnect the transport unit 32 to the winch 24, deactivate the holding device 36, and enter a downward target travel instruction at the upper control unit 56. After the target travel instruction is transmitted from the upper control unit 56 to the main control unit 30, the latter activates the winch 24 downward until the transport unit 32 reaches the lower target position. The described procedure can then be repeated. It is also possible that the installation system does not have a holding device for the transport unit. In this case, the installation material is loaded into the transport unit in another way, for example, using another winch.unloaded from the vehicle body.

[0059] The installation system 112 according to Fig. 2 is very similar in structure to the installation system 12 according to Fig. 1, which is why only the differences between the installation system 112 and the installation system 12 according to Fig. 1 will be discussed.

[0060] In the installation system 112 according to Fig. 2, a lower control unit 152 is arranged on a carriage 132.
