Description

Technical Field

[0001] The present invention relates to an earth-working machine according to the preamble of claim 1, comprising: a transport implement including a movable underframe, particularly including a tracked chassis; a working device designed to perform earthwork or rockwork operations, particularly removing soil or rock, or introducing structures into the soil; and at least one steel cable subjected to tension at least temporarily and adjustable in the longitudinal cable direction by means of a cable drive.

[0002] The present invention relates to a method for operating earthmoving machinery according to the preamble of claim 12, the earthmoving machinery comprising: a transport implement including a movable underframe, particularly including a tracked chassis; a working device by means of which earthmoving or rockmoving operations are performed, particularly removing soil or rock, or introducing structures into the soil; and at least one steel cable subjected to tension at least temporarily and adjusted along the longitudinal cable direction by means of a cable actuator. Background Technology

[0003] Ordinary earthmoving machinery has been in use for a long time, especially as construction machinery, such as earth drills or diaphragm wall equipment. These earthmoving machines typically use multiple steel cables to actuate mechanical components. For example, in earth drills, a so-called main cable, including a main cable winch, is arranged, by means of which the drilling tool, particularly a square drill rod, can be raised and lowered along the mast. Additionally, a so-called feed cable is used, by means of which the drill drive sliding mechanism can be adjusted along the mast, for example, by means of a feed winch. As a result, additional feed force can be applied to the drilling tool, for example. Furthermore, other steel cables, such as so-called auxiliary cables, can be arranged on these earthmoving machines, which can provide additional lifting or traction functions by means of an auxiliary cable winch.

[0004] The steel cable used in this type of earthmoving machinery offers the following advantages: high tension can be applied to mechanical components (e.g., working tools) via a drive mechanism (e.g., a cable winch) positioned at a distance from the component. The cable path can be predetermined using one or more deflection rollers. Furthermore, the cable can be wound very compactly onto the winch drum, allowing for the provision of varying working lengths for efficient force transmission.

[0005] This type of steel cable is composed of multiple so-called cables, specifically wound axially. In this case, multiple cables can be combined into strands, and the steel cable itself can be composed of multiple such strands. Therefore, a high-strength and flexible cable can be formed.

[0006] In earthmoving machinery, especially construction machinery, steel cables are subject to considerable wear. In this case, the wear is particularly dependent on the duration of use, the force applied to the cable, the type and amount of winding, and environmental and weather conditions, which can be extreme, especially at outdoor construction sites.

[0007] This wear, in particular, can cause the individual cables in the cable to break. The cable may lose more than a certain amount of its required strength, and a certain number of cables within the cable may break. At levels of wear exceeding a certain threshold, malfunctions, i.e., cable breakage, may occur during operation. Cable breakage during the operation of earthmoving machinery can have serious consequences, not only causing excessive damage to the earthmoving machinery itself or nearby equipment, but also posing a risk to life and limb to personnel on or in the area of ​​the earthmoving machinery. Therefore, cable breakage on earthmoving machinery must be avoided at all costs.

[0008] It is known and routine to periodically visually inspect the steel cables used on earthmoving machinery for surface breakage and replace them after a predetermined number of operating hours. However, this method also has drawbacks. First, if the number of operating hours before replacing the steel cables is set too low, steel cables that are still fully functional and unworn are often replaced and discarded. This is economically inefficient, as such cables could still be used further.

[0009] Furthermore, if earthmoving machinery is used intensively, especially under extreme weather conditions, cable wear may occur at an earlier point in time, and in such cases, the scheduled replacement of the cables may be too late. In these rare but real occurrences, there is also a risk of injury to personnel and machinery.

[0010] Inspection methods and equipment for inspecting steel cables are known, such as those using electromagnetic waves. For example, this inspection method allows for the non-destructive identification of individual cable breaks within the cable. For instance, in electromagnetic surveying of steel cables, cable breaks can be identified as anomalies in the measurement records.

[0011] This inspection method and the measuring equipment used are complex. The measuring equipment must be precisely positioned on the cable, and the inspection needs to be performed by trained inspectors. For example, these inspections are used for particularly expensive and safety-related cables, such as those on cable cars used to transport people. Cable cars use very long cables, sometimes thousands of meters in length. Even relatively small temperature variations can cause significant changes in length and thus different cable paths. The measuring equipment can be flexibly positioned on such cable car systems using a belt system, where the cable to be inspected is guided through the measuring equipment or the measuring equipment is guided along the cable. This inspection is time-consuming and expensive. Summary of the Invention

[0012] The objective of this invention is to specifically describe an earthmoving machine and a method for operating the earthmoving machine, by means of which the use of steel cables is ensured to be particularly economical and safe during operation.

[0013] According to the present invention, this objective is achieved by both the earthmoving machinery having the features of claim 1 and the method for operating the earthmoving machinery having the features of claim 12. Preferred embodiments of the invention are set forth in the dependent claims.

[0014] According to the invention, earthmoving machinery is configured to include at least one holding device designed to receive and detachably hold a cable measuring unit, the cable measuring unit including a cable passage channel and designed to detect the cable state in the area of ​​the cable passage channel, and the holding device is arranged in the area of ​​the cable such that when the cable measuring unit is received, the cable measuring unit is held in a defined position in which the cable is properly guided through the cable passage channel.

[0015] This invention is based on the understanding that steel cables used at numerous points on earthmoving machinery have defined cable paths. Based on this understanding, according to one aspect of the invention, at least one holding device is arranged on the earthmoving machinery, designed to receive and detachably hold a cable measuring unit in a predetermined position. The cable measuring unit may include an open or preferably closed cable passage, wherein the state of the steel cable guided through the cable passage can be detected by the cable measuring unit. With the aid of this holding device, the defined position of the cable measuring unit can be predetermined during the measurement process, such that the steel cable is properly guided through the cable passage, where particularly reliable measurements can be performed.

[0016] The working device can be designed to remove soil or rock, for example as a drilling tool or a cutter, or to introduce structures into the soil, preferably as a piling machine or vibratory machine, to introduce foundation elements (such as sheet piles or columns) into the soil.

[0017] In principle, measuring instruments can be positioned on the holding device for extended periods. According to another aspect of the invention, the holding device positioned on earthmoving machinery allows for the temporary use of relatively expensive cable-stayed measuring units on the machinery, wherein the cable-stayed measuring unit can be quickly installed in the correct position and quickly disengaged due to the predetermined positioning of the holding device. This allows for a highly efficient measurement process using cable-stayed measuring units.

[0018] For the measurement process, the steel cable can preferably be moved through the cable measuring unit by means of a cable actuator. In this way, it is possible to detect and inspect larger sections of the cable for possible cable breaks in a non-destructive manner. The cable measuring unit can specifically perform electromagnetic surveys of the steel cable, particularly the MRT method, in which, for example, the steel cable is guided through an electromagnetic inspection field. Cable breaks, defects, or cracks in the steel cable can cause anomalies during the inspection. By means of the condition inspection of individual steel cables thus performed, breaks, wear, or other faults can be identified in a timely manner, and therefore, the safety risks to operators and earthmoving machinery are significantly reduced. Unnecessary premature replacement of cables with only slight wear is also prevented.

[0019] According to one embodiment of the invention, it is particularly preferred that the cable actuator include a cable winch and / or a linear actuator. Using such a cable actuator, the steel cable can be efficiently moved and guided through the cable measuring unit. It is preferable that the cable actuator include at least one cable winch, on which the steel cable is at least partially mounted and can be adjusted in its longitudinal cable direction by means of winding movement. It is particularly advantageous that the cable actuator, designed to include a cable winch, is formed in the lower half of the mast or guide rod of the earthmoving machinery according to the invention, particularly on the rear side of the mast, or on the transport implement, particularly on the superstructure. As a result, depending on the arrangement and orientation of the cable measuring unit, the steel cable can be guided particularly easily through the cable measuring unit.

[0020] In principle, the retaining devices can be arranged on earthmoving machinery in any manner. In this case, it is particularly preferred that two or more retaining devices be arranged at different points on the earthmoving machinery, wherein the state of a single cable and / or the state of two or more cables can be detected at different points by means of one or more cable measuring units. It is particularly advantageous to arrange the two or more retaining devices on the working slide on the masthead, the rear side of the mast, or the front side of the mast. In particular, it is particularly preferred that the cable measuring units be arranged between two or more deflection rollers and / or deflection blocks. As a result, the cable can be guided through the cable measuring units in a particularly efficient and stable manner. Furthermore, this ensures a particularly simple attachment of the cable measuring units to the earthmoving machinery according to the invention.

[0021] It is preferable to include a data storage unit in the cable measurement unit for local storage of detected cable condition data. Preferably, in addition to the cable measurement unit, an arithmetic logic unit may be provided, connected to the data storage unit, and designed to evaluate and process the detected cable condition data. This evaluation may specifically include cable condition analysis and usage recommendations. In this case, the arithmetic logic unit may be spatially separated from the cable measurement unit, particularly as a mobile arithmetic logic unit, such as a smartphone or tablet. As a result, the obtained measurement data can be evaluated in a spatially flexible manner and independently of the corresponding location of the earthmoving machinery according to the invention. In this case, it is particularly preferable to display the data detected by the cable measurement unit graphically in a two-dimensional manner via a display device.

[0022] Another advantageous aspect of the invention is that the retaining device includes a fastening device for detachably securing the cable measuring unit. This fastening device can be specifically designed as a screw connection and / or an insert connection. It is particularly advantageous to design the fastening device to insert the cable measuring unit between two opposing metal plates. Designing the fastening device as a bent portion is also suitable. With the aid of the fastening device according to the invention, the cable measuring unit can be mounted on earthmoving machinery in a flexible and demand-based manner, allowing for particularly economical operation.

[0023] According to another improvement of the invention, it is advantageous to include a receiver comprising at least one stop for positioning the cable measuring unit correctly within the retaining device. This receiver may, in particular, have a rectangular basic shape with lateral support walls. In this way, particularly accurate cable guidance of the cable measuring unit on earthmoving machinery according to the invention can be ensured. Similarly, this construction of the retaining device simplifies the installation of the cable measuring unit on earthmoving machinery.

[0024] An additional advantageous configuration of the invention is that the retaining device includes an adjusting device, particularly including at least one adjusting screw, for adjusting the receiving position of the cable measuring unit. This adjusting screw is preferably configured to permanently fasten the cable measuring unit to the fastening device. Preferably, the adjusting device can be inserted, particularly screwed, into the measuring device. As a result, simple and precise attachment of both the retaining device and the cable measuring unit can be ensured. The adjusting device also allows for movable retention, such that the position of the cable measuring unit can be continuously adjusted to accommodate the path of the cable being guided through.

[0025] In a preferred embodiment of the invention, the retaining device may be arranged on a cable drive or a deflector roller for the cable. Specifically, the retaining device may be arranged on a deflector block for guiding the cable on earthmoving machinery. Particularly preferred is that the retaining device is arranged between two deflector rollers on the masthead of the earthmoving machinery, preferably centrally located on the upper side. The retaining device may also preferably be arranged on the rear side of the mast. In this manner, a particularly efficient installation of the cable measuring unit on the earthmoving machinery can be performed.

[0026] A particularly suitable configuration of the invention involves earthmoving machinery comprising at least two steel cables arranged side-by-side, particularly parallel to each other, and a holding device that is adjustablely and particularly repositionably mounted between a first measuring position for the first steel cable and at least one additional measuring position for at least one additional steel cable. In this configuration, the steel cables can be specifically designed to actuate the earthmoving device. Specifically, the steel cables can be designed as adjustable base slides on the mast that actuates the earthmoving machinery in the feed or lifting direction. Alternatively or supplemented, cables can be provided for holding the working device on the masthead or extension arm. With earthmoving machinery designed in this manner, various steel cables can be detected and inspected particularly efficiently by means of a cable measuring unit, ensuring particularly safe operation of the earthmoving machinery even when using multiple cables. Due to the adjustability of the holding device, the same cable measuring unit can be used to inspect multiple steel cables, which reduces costs.

[0027] According to a variation of an embodiment of the invention, the earthmoving machinery is configured such that it includes a mast or extension arm, along which at least one steel cable is guided, and at least one retaining device is arranged in the head region of the mast or extension arm. The head region of the mast may specifically include at least one deflector roller for changing the cable running direction of the at least one steel cable, wherein the steel cable is guided from the rear side of the mast to the front side. Particularly advantageously, the retaining device is configured to secure a cable measuring unit to the earthmoving machinery between two deflector rollers in the head region of the mast. The retaining device may also be arranged in the lower feed region of the deflector rollers. In this way, areas of particularly high load on the steel cable can be detected and inspected by the cable measuring unit.

[0028] In a preferred embodiment of the invention, the earthmoving machinery is configured to include a control unit, and a cable measuring unit is connected to the control unit via wired or wireless means for evaluating and outputting measurement data or results. Consequently, data related to the state of the steel cable detected by the cable measuring unit can be directly processed and evaluated by the control unit. Therefore, the cable measuring unit can be permanently maintained at a predetermined position on the earthmoving machinery, where the detected data can be read out by the operator of the earthmoving machinery in a particularly simple manner. Advantageously, the control unit is located on the upper structure of the earthmoving machinery, particularly in the vehicle's cab. In this case, the control unit includes at least one output device, such as a display, VR glasses, a tablet computer, or another unit for graphically or digitally representing the detected state data of the steel cable.

[0029] Advantageously, the control unit includes an arithmetic logic unit and / or a data memory for processing the detected cable condition data. Therefore, the cable condition data can be processed and evaluated immediately after detection by the cable measuring unit. According to the invention, it is particularly suitable that the cable condition data detected by the cable measuring unit is processed and evaluated by the control unit, wherein a graphical representation (e.g., a cable profile) relating to the condition of the at least one cable based on the detected cable condition data is output, and in particular, alphanumeric suggestions, such as those for further use of the cable on earthmoving machinery, are also output. This graphical representation can preferably be correlated with any detected anomalies.

[0030] In another preferred embodiment of the earthmoving machinery according to the invention, the earthmoving machinery is configured as a soil drill, mud wall implement, vibratory implement, or pile driver. Preferably, the earthmoving machinery according to the invention includes at least one rotary drive comprising earthmoving tools, such as a cutting wheel or auger for rotatably penetrating into the soil. This at least one steel cable may be specifically designed to adjust the position of the earthmoving tools on the earthmoving machinery, for example, for penetrating into the soil and / or raising them outward from the soil. In this respect, the earthmoving machinery according to the invention can be particularly flexible for use in various application areas.

[0031] The method according to the invention is characterized in that the earthmoving machinery includes at least one holding device by means of which a cable measuring unit is received and detachably held, the cable measuring unit including a cable passage channel, and the cable measuring unit is arranged in the area of ​​a steel cable by means of the holding device such that the steel cable is properly guided through the cable passage channel of the cable measuring unit, and the state of the steel cable is detected by the cable measuring unit in the area of ​​the cable passage channel.

[0032] This method can be particularly used in earthmoving machinery according to the invention as described above. Thus, the aforementioned advantages can be achieved.

[0033] A preferred variation of the invention involves adjusting the cable along its longitudinal direction using a cable actuator, wherein the cable moves through a cable passage channel of the cable measuring unit, and the condition of the cable is detected over its length during this process. In this way, the condition of a particularly large portion of the cable can be permanently monitored. Particularly advantageous is to monitor the entire cable profile over its length while simultaneously monitoring the cable's condition. It is advantageous to adjust the cable in its longitudinal direction such that at least one-tenth of the total length of the cable passes through the cable passage channel of the cable measuring unit and is detected. With this configuration, the condition of the cable can be assessed particularly reliably.

[0034] According to another improvement of the invention, it is advantageous to arrange at least one cable measuring unit only temporarily on the holding device and then detach and remove it again. By attaching the cable measuring unit in a demand-based manner, particularly economical and efficient operation of the earthmoving machinery is ensured. For example, the cable measuring unit can thus be used on multiple earthmoving machines instead of being permanently attached to a single machine. In particular, it is advantageous to arrange at least one cable measuring unit sequentially on multiple holding devices of the earthmoving machinery according to the invention, and then detach and remove it again, wherein the holding devices are arranged at different locations on the earthmoving machinery, thus expanding the detectable portion of one or more cables. As a result, portions of the cable that were not detected when winding or unwinding the cable due to the first position of the cable measuring unit can also be inspected. Therefore, the area of ​​the cable detected by the cable measuring unit is expanded, and safety is improved.

[0035] According to a particularly advantageous configuration of the invention, the measured values ​​detected by the cable measuring unit are stored in a storage device, and preferably evaluated remotely from the earthmoving machinery using an arithmetic logic unit. In principle, in this case, the detected measured values ​​can be stored by the storage unit of the cable measuring unit and / or by the storage unit of the arithmetic logic unit. The measured values ​​detected by the cable measuring unit can be evaluated, in particular, using a cable condition detection algorithm of the arithmetic logic unit, wherein the cable condition is analyzed using the detected cable condition data according to the cable condition detection algorithm (especially using machine learning). In this way, for example, specific recommended actions for cable maintenance can be output to the operator of the earthmoving machinery, and particularly safe operation can be ensured.

Detailed Implementation

[0037] Figure 1 Earthmoving machinery 10 according to the invention is shown, comprising a transport implement 12. The transport implement 12 may preferably comprise a tracked chassis as a base frame 14, on which a superstructure 16 may be rotatably mounted. A controller 60 for the earthmoving machinery 10 may be located in the operator's cab of the superstructure 16. In principle, as shown herein, the earthmoving machinery 10 may be designed as civil engineering machinery.

[0038] A mast 20, which may be designed as a leader 21 and have an upright, substantially vertical position during operation, may preferably be adjustably mounted on the superstructure 16, particularly via a hinge mechanism 18. The mast 20 may also be directly connected to the superstructure 16, particularly via a joint (not shown) arranged in the lower region of the mast 20 and one or more actuating cylinders (not shown). A boom (not shown) may also be bendable to be adjustably positioned on the superstructure 16, rather than on the mast 20.

[0039] According to the exemplary embodiment shown, the mast 20 may preferably be designed as a guide rod 21 including a linear guide 24 on its front side. For example, a base slide 38 including a rotary drill drive 36 may be vertically movably mounted along the linear guide 24. As a result, the earthmoving machinery 10 may be configured as a drilling tool. In the figures, an exemplary center position and a lower position indicated by dashed lines are shown for the rotary drill drive 36.

[0040] A cable, particularly a first steel cable 40 serving as the main cable 42, may be guided at the mast head 22 at the upper end of the mast 20. At one end of this cable, a preferably telescopic prismatic drill rod 32, including an exemplary auger 34, may be mounted for forming the working device 30, particularly a civil engineering tool. The prismatic drill rod 32 may be guided by a sleeve-shaped drive wheel of a rotary drill drive 36 arranged on a base slide 38, such that torque from the rotary drill drive 36 is transmitted to the prismatic drill rod 32, for example, via a drive belt (not shown). The auger 34 may be arranged on the lower end of the prismatic drill rod 32 for forming a borehole in the ground. In principle, the drilling tool can be designed in any manner and may particularly include the auger 34 or a drill bucket.

[0041] The steel cable 40 can be guided from the square drill pipe 32 along the mast 20 via the deflection roller 26 on the mast head 22 to the cable actuator 46 in the superstructure 16. For example... Figure 1 As illustrated by example, a cable measuring unit 80 may be formed on the mast head 22 of the mast 20 for detecting cable status data. The cable measuring unit 80 may preferably be centrally formed between the first and second deflection rollers. An auxiliary cable (not shown here) may preferably extend parallel to the first steel cable 40 as another steel cable, wherein the cable measuring unit 80 may be designed to detect cable status data of the auxiliary cable and / or the steel cable.

[0042] The cable actuator 46 is driven by a motor 50, particularly an electric or hydraulic motor, which can also operate in retraction mode. The square drill rod 32, including the auger, can be raised and lowered via the cable actuator 46 by means of a steel cable 40.

[0043] The base slide 38, including the rotary drill drive 36, can be pulled upwards via another cable 40, specifically designed as a feed cable 44, by means of a feed winch 28 (particularly an actuator), which includes a winch on the mast 20. The base slide 38, including the rotary drill drive 36, can also be lowered downwards by correspondingly driving the feed winch 28 in the opposite direction. The base slide 38 can also be pulled downwards via the feed winch 28.

[0044] The rotary drilling rig drive 36 can be formed from a top drive including at least one additional motor. The feed winch 28 can also be configured to have a motor (not shown), such as an electric motor or a hydraulic motor. The at least one motor 50 is actuated by means of a controller 60 to operate the cable drive 46, and the additional motor is preferably also actuated to operate the feed winch 28. In principle, the feed winch 28 shown herein can also be designed as an actuation unit.

[0045] The control unit 60 may specifically include an arithmetic logic unit, a data memory, and / or a communication unit, and may be data-connected to the cable measurement unit 80. In principle, the cable measurement unit 80 may also include an arithmetic logic unit, a data memory, and / or a communication unit, and may be designed to receive data, particularly control commands.

[0046] For example, data detection of the cable measurement unit 80 can be started, stopped, or adjusted by an operator inputting control commands. Data can be stored, specifically, by the storage unit of the cable measurement unit. Similarly, data from the cable measurement unit can preferably be stored and / or processed by a separate arithmetic logic unit, wherein evaluation can also be performed by another arithmetic logic unit with a time delay. The cable measurement unit 80 can preferably be connected to the control unit 60 via wired and / or wireless means. In the same manner, the control unit 60 can be connected to a mobile arithmetic logic unit for storing and / or graphically representing the detected cable state data, and for outputting usage recommendations based on the cable state data detected by the cable measurement unit 80. Therefore, the control unit 60 can preferably be designed to prepare and analyze the detected cable state data, particularly for outputting usage recommendations. A mobile arithmetic logic unit, such as a tablet or smartphone, can be specifically provided to input control commands into the control unit 60 and / or the cable measurement unit 80. The control unit 60 may preferably be integrated into the earthmoving machinery 10, particularly the superstructure 16, and may include at least one monitor for operation by an operator.

[0047] Figure 1 The first steel cable 40 and all other mentioned cables, particularly the main cable 42 and feed cable 44, shown may be specifically formed from multiple strands, wherein the cable measuring unit 80 may be designed to detect the condition of each cable. The detected condition data can be evaluated by the cable measuring unit 80 and / or the control unit 60, whereby weaknesses in the steel cable 40 can be identified in a timely manner. In this case, the detected cable condition data can be output along with warning messages, particularly in the cab of the earthmoving machinery 10. The detected data can also be output to regional remote users, for example, via the Internet.

[0048] The following text will refer to Figure 2 and Figure 3 The earthmoving machinery 10 according to the invention, including the cable measuring unit 80, will be explained in more detail. Figure 2A side view of the mast head 22 of a modified earthmoving machinery 10 is shown, wherein a cable measuring unit 80 is arranged in the central region between a first deflector roller 26 and a second deflector roller. As shown here, the cable measuring unit 80 can be held, in particular, at an angle relative to the vertical direction by means of a holding device 70 parallel to the cable 40. Specifically, the cable 40 can pass through the center of the cable measuring unit 80, wherein the measuring path of the cable measuring unit 80 can be oriented parallel to the cable's direction of passage. The cable 40 (by way of example, it is designed here as the main cable 42 for supporting and adjusting the drilling tools) can pass through the cable measuring unit 80 in a straight line between the two deflector rollers, wherein the angle of the cable 40 relative to the horizontal direction is between 0º and 90º, and in particular, as shown here, between 30º and 60º. Figure 2 and Figure 3 The cable measuring unit 80 shown is arranged differently in the central region. Preferably, the cable measuring unit 80 can also be arranged in the side region of the connecting axis between the first and second deflection rollers of the mast 20.

[0049] Figure 3 An enlarged perspective view of a cable measuring unit 80 on an earthmoving machine 10 is shown, wherein the cable measuring unit 80, including a retaining device 70, is arranged on a mast head 22. As shown here, the retaining device 70 can be secured to the mast head 22, specifically by a fastening device 72. For this purpose, a plurality of screw connections are preferably provided. The retaining device 70 can particularly have a rectangular basic shape having two opposing support plates. As shown here, the retaining device 70 can laterally surround the cable measuring unit 80, such that there is a secure connection between the cable measuring unit 80 and the frame of the mast head 22. The retaining device 70 can particularly be arranged such that a steel cable 40 passes through the center of the cable measuring unit 80 in the longitudinal direction.

[0050] The following text will refer to Figures 4 to 7 The arrangement of the cable measuring unit 80 according to the invention on the earthmoving machinery 10 will be explained in more detail. Figures 4 to 7 Each illustration shows another exemplary arrangement of the cable measuring unit 80 on the earthmoving machinery 10, wherein the cable measuring unit 80 is configured to detect cable status data of the feed cable 44 (here, another steel cable 40). However, another steel cable 40, particularly the main cable 42, can pass through the illustrated embodiments in the same manner, and these embodiments can be designed to detect their cable status data.

[0051] Figure 4An exemplary arrangement of the cable measuring unit 80 is shown, which is here fastened to the deflector block 27 of the earthmoving machinery 10. As shown, in this configuration, the feed cable 44 can pass longitudinally through the cable measuring unit 80 in the cable passage 90. The cable measuring unit 80 can preferably be attached to the earthmoving machinery 10 by a retaining device 70 and a fastening device 72. In principle, the retaining device 70 and the fastening device 72 can be designed in any manner. Figure 4 As shown, the fastening device 72 may be specifically designed for adjusting the cable measuring unit 80 onto the feed cable 44. As shown here, the retaining device 70 may preferably be designed as a retaining frame penetrated by two guides, wherein the cable measuring unit 80 is mounted on the guides by a plurality of screws.

[0052] Figure 5 A variation of the embodiment is shown in which the cable measuring unit 80 is arranged on the rear side 23 of the mast and the steel cable 40 passes through the cable measuring unit 80. Here, the cable measuring unit 80 and the holding device 70 can, in principle, be arranged along the mast 20 in any manner. As shown here, the holding device 70 can be specifically formed by two opposing holding elements, which include symmetrically introduced guides by means of which an adjustment device is formed for changing and adjusting the position of the received cable measuring unit 80.

[0053] Figure 6 Similarly, cable state detection is exemplarily shown by means of a cable measuring unit 80 on the rear side 23 of the mast prior to cable deflection (not shown here). As shown here, the holding device 70 may preferably be designed as a rectangular receiving element for receiving the cable measuring unit 80.
