Description

[0001] The invention relates to a transport device for transporting a cable drum with a central bore.

[0002] Furthermore, the present invention relates to an adjusting element for the aforementioned transport device.

[0003] Transport devices for bulky elements are well known, although not specifically suitable for cable reels. GB 2 390 997 A, for example, discloses a portable tool with a rigid shaft, U-shaped lower edge support, and a movable holding element for securing the upper edge of a panel. GB 2 492 556 A describes a length-adjustable panel carrier with a handle and U-shaped load-bearing part for guiding large-format fence or wall panels. US 139 029 A discloses a "box lifter" with a curved support bar, underside claw, and height-adjustable fork clamp, which grips boxes with a positive and force fit and allows them to be lifted without direct hand contact. US 4 098 442 A shows a panel carrier with a triangular handle, load rest at the bottom and forward-facing holding claws as well as an elastic buffer to protect sensitive panels such as glass panes.Finally, GB 2 171 352 A discloses a symmetrical lifting and carrying tool with a triangular handle, base plate or carrying sections and upstanding safety fingers, which can also ergonomically pick up heavy or irregularly shaped plates.

[0004] In a conventional manner, cable reels are transported by inserting a support shaft into a central bore of a cable reel. Next, the two ends of the support shaft are lifted via a rope arrangement for subsequent transport of the cable reel, or are grasped by two human transporters and lifted for subsequent transport of the cable reel. It is therefore advantageous that options have been created for transporting cable reels. Particularly when a cable reel, for example a fully wound cable reel, has to be transported up steps in a hallway, safe carrying by one, two, or more human transporters without aids, taking health and occupational safety into account, cannot be guaranteed.However, the support axle has the problem that it does not prevent the cable reel from shifting along its longitudinal axis, so that the cable reel constantly threatens to crush the hand or fingers of one of the reel operators, especially when two people of different sizes are involved. Thus, the known devices do not provide adequate health or occupational safety.

[0005] An alternative solution is therefore disclosed in published patent application DD 2 04 458 A1. This application proposes a load hook for cable reels whose center of gravity is selected such that the load hook stabilizes itself after being inserted into the central bore of the cable reel. Two load hooks are used to safely transport the cable reel. The shape of the load hook is intended to anchor it to the cable reel by positive locking without the need for additional parts. The principle of the load hook can be used for cable reels of different masses and sizes; however, the strength of the material and the dimensions of the load hook must be varied accordingly.

[0006] The load hook is connected to a sling at its end facing away from the cable drum via a shackle. The sling thus supports the cable drum for transporting the cable drum. If two transporters transport the cable drum, for example a fully wound cable drum, up a hallway via steps, each transporter holds one end of the sling. Since the load hook stabilizes itself firmly once inserted into the center hole of the cable drum, flexibility is enabled by a corresponding sling. The problem here, however, is that this flexibility of the sling reduces the safety of the transporters during transport. While the cable drum is transported by two transporters, each transporter grasps one sling.However, slings are not suitable for ensuring that a conveyor operator's hand does not strike a front pulley facing them. Thus, conveyor operators are exposed to a risk of injury under the aforementioned circumstances. This conflicts with occupational safety. Occupational safety is the safety of employees at work, i.e., the control and minimization of risks to their safety and health. For example, it is a component of occupational health and safety within the meaning of the Occupational Safety and Health Act applicable in the Federal Republic of Germany, which requires measures to prevent accidents at work and work-related health hazards, including measures to ensure humane work design.Managing the safety and health of employees is one of a company's essential support processes, primarily for human reasons, but also from an economic perspective: accidents and work-related illnesses cost both companies and society a lot of money.

[0007] The object of the invention is therefore to provide a transport device for transporting a cable reel that enables the cable reel to be transported safely by a human operator. It should also be possible for two human operators to each use a transport device to transport the cable reel safely.

[0008] The object is achieved according to the invention by a transport device having the features of claim 1. Preferred embodiments of the invention are specified in the subclaims and the following description, which may each individually or in combination represent an aspect of the invention.

[0009] According to the invention, a transport device for transporting a cable drum with a central bore and a rotation axis is thus specified, comprising a gripping means for gripping by a user during transport of the cable reel, a longitudinal guide body arranged on the gripping means with a longitudinal axis of extension, a U-shaped hook arrangement arranged on the longitudinal guide body for hooking into the central bore of the cable drum, wherein the hook arrangement has an outer web with an outer web extension axis, a load web and a hooking web with a hooking web extension axis, wherein the hooking web is designed for abutment on the cable drum, wherein the longitudinal extension axis of the longitudinal guide body and the outer web extension axis of the outer web are arranged at an acute angle to one another, the acute angle being between 15 degrees and 25 degrees inclusive.

[0010] The basic idea of ​​the present invention is therefore that the transport device has a longitudinal guide body which, when the transport device is hooked into the cable drum, is arranged such that the gripping means is always spaced from the cable drum. This means that there is no risk of injury to a human transporter who has his hand in the gripping means and is transporting the cable drum. In other words, this means that the cable drum cannot slide further along the axis of rotation, thus preventing the transporter's hand from being injured, in particular crushed. It has been found that the angle between the longitudinal extension axis of the longitudinal guide body and the outer web extension axis of the outer web is particularly advantageous as an acute angle. An acute angle is an angle that is less than 90 degrees.The angle is preferably less than or equal to 60 degrees, particularly preferably less than or equal to 45 degrees. It should be noted that as the angle decreases, greater stability is achieved during transport. A decreasing angle therefore increases transport safety because transport is less unstable. On the other hand, as the angle increases, the distance between the gripping device and the cable reel is greater, which also increases work safety because there is no risk of impacts or crushing of the hand from a wobbling cable reel during transport. The final angle can therefore depend on the dimensions of the cable reel to be transported.

[0011] According to the invention, an adjusting element for the aforementioned transport device is also specified.

[0012] The invention preferably relates to a set of two transport devices, each of which can be used to open a front plate of a cable reel to be transported. Particularly preferably, one human transporter per transport device is used. The use of two transport devices can be advantageous, particularly for heavy cable reels. This ultimately depends on the strength and size of the human transporters, the dimensions and weight of the cable reels, and national occupational health and safety regulations.

[0013] In the sense of the invention, abutment means that forces are absorbed, whereby this means that the abutted component is also fixed and secured against unintentional slipping during the transport of a cable drum.

[0014] The transport device is intended in particular for transporting a cable reel. Preferably, its suitability is also extended to include lifting and setting down the cable reel. Suitability for lifting, transporting, and setting down is then understood as conveying.

[0015] In particular, the longitudinal axis of the longitudinal guide body is designed to run at an angle to the main plane of the end plate to be supported. In combination with a translationally displaceable or movable adjustment element, this has the advantage of allowing cable reels with end plates of different thicknesses to be transported. This increases the flexible applicability of the transport device while ensuring safe transport at all times.

[0016] Preferably, the hooking web extension axis runs parallel to the main extension plane of the end plate to be supported.

[0017] A cable reel typically comprises a hollow cylinder with a rotational axis, each of which has an end plate with an opening at each of its two ends. In particular, the openings of the end plates and the hollow cylinder are arranged coaxially to one another such that the cable reel has a central bore extending through the two end plates and the hollow cylinder. The openings of the end plates preferably have a radially smaller diameter than the inner diameter of the hollow cylinder.

[0018] The cable reel is, in particular, a cable reel. The cable reel is particularly preferably a cable reel for data cables, in particular for fiber optic cables.

[0019] In particular, the adjustment element is a sliding element.

[0020] The U-shaped design of the hook arrangement means that the basic shape resembles the letter "U" in the Latin alphabet. This should be understood as an approximate description. A U-shape is closely based on a V-shape, whereby a V-shaped hook arrangement, for example, has a smaller load-bearing web. For example, the outer web, the load web and the hooking web can be arranged one after the other at a right angle to one another. This corresponds to an embodiment of a U-shape. It is also possible for the outer web and the hooking web to each have an obtuse angle to the load web; this corresponds to a U-shape with an inclination towards a V-shape, although this can also be understood as a U-shape. Finally, according to one embodiment of the hook arrangement, the load web can be designed to be so small that the outer web and the hooking web in particular act as load-bearing components of the end plate.This visually corresponds to a V-shape, which can also be defined as a U-shape.

[0021] As mentioned, according to the invention, the acute angle is between 15 degrees and 25 degrees inclusive. This therefore means in particular that the acute angle can be between 15 degrees and 16 degrees inclusive, between 15 degrees and 20 degrees inclusive, between 16 degrees and 25 degrees inclusive, or between 20 degrees and 25 degrees inclusive. It has been found that these angular ranges are particularly suitable for reducing the risk of injury to transporters during the transport of cable reels and thus increasing occupational safety. The main load of the cable reel is carried mainly vertically and at the same time it is ensured that the gripping means is spaced away from the end plate of the cable reel during transport.

[0022] According to an advantageous embodiment of the invention, the acute angle is between 16 degrees and 20 degrees inclusive. This angle range has been found to be particularly suitable for reducing the risk of injury to transporters during the transport of cable reels and thus increasing occupational safety. The main load of the cable reel is carried primarily vertically, while simultaneously ensuring that the gripping device is kept at a distance from the end plate of the cable reel during transport.

[0023] According to an advantageous embodiment of the invention, the hook arrangement is U-shaped such that the hooking web has an end section such that, during transport of the cable drum, the end section is arranged pointing in a direction opposite to the weight of the cable drum. This means that the end section is directed upwards during transport of the cable drum. Advantageously, the cable drum, through its own weight, thus ensures that the end section does not fall out of the respective opening of the cable drum during transport of the cable drum.

[0024] According to an advantageous embodiment of the invention, the load bar has a load bar extension axis that is arranged at a respective angle perpendicular to the outer bar extension axis and / or the hooking bar extension axis. This means that the U-shape of the hook arrangement is realized in that the outer bar extension axis and the hooking bar extension axis are arranged parallel to each other and the load bar extension axis is perpendicular to the outer bar extension axis and the hooking bar extension axis. This ensures secure support of the storage drum during transport of the cable drum.

[0025] According to an advantageous embodiment of the invention, the outer web extension axis and the hooking web extension axis are arranged parallel to each other. This ensures secure support of the storage drum during transport of the cable drum.

[0026] According to an advantageous embodiment of the invention, the longitudinal guide body has a non-circular cross-section in cross-section relative to the longitudinal axis. In particular, the longitudinal guide body has a square cross-section relative to the longitudinal axis. "Circular" in the context of the invention means that a cross-section always has the same radius from its outer edge to its center. A non-circular cross-section has the advantage that attached elements, such as an adjusting element, can be added in a rotationally fixed manner. Furthermore, circular cross-sections, in particular, are expensive to manufacture.

[0027] According to an advantageous embodiment of the invention, the gripping means is designed in particular as a loop handle or a T-handle and is preferably detachably connected to the longitudinal guide body. A loop handle comprises an oval contour, whereby two parallel struts can also be provided, closed by semicircular elements. Thus, the first strut is used for holding with the hand and the second strut for connecting to the longitudinal guide body. A design as a loop handle has the advantage that the transporter can thus hold the gripping means by the first, upper strut and has his fingers protected from impacts with the cable drum by the lower strut. The T-handle, in contrast, is cheaper to manufacture.

[0028] The optionally preferred detachable connection between the gripping device and the longitudinal guide body is implemented, for example, by a screw connection or similarly acting connection. One advantage is that this allows for the replaceable adjustment element. Due to the constant stress during transport, the adjustment element is exposed to an increased risk of material damage. Therefore, it can be advantageous for the adjustment element to be easily replaced by removing the detachable connection, inserting an alternative adjustment element, and then closing the detachable connection again. Furthermore, detachable connections are advantageous over thermal joints because these can influence the material structure and thus create weak points.

[0029] According to an advantageous embodiment of the invention, the transport device comprises an adjusting element with a contact body, wherein the adjusting element is translationally movable along the longitudinal axis of the longitudinal guide body, in particular in a rotationally secure manner, in order to abut a front plate of the cable drum with the contact body during transport of the cable drum. For example, the adjusting element can comprise a guide sleeve that encloses the longitudinal guide body for the translational movement of the adjusting element along the longitudinal axis, wherein the guide sleeve is at least indirectly connected to the contact body. At least indirectly means that the contact body can be arranged directly on the guide sleeve or that the contact body can be arranged indirectly on the guide sleeve via a spacer element.This means that the same transport device is suitable for transporting cable reels with end plates of different thicknesses. As the thickness of the end plates increases along the rotation axis of the cable reel, the adjustment element must be guided upwards along the longitudinal axis of extension; as the thickness of the end plates decreases along the rotation axis of the cable reel, the adjustment element must be guided downwards along the longitudinal axis of extension until the end plate is securely clamped between the hooking bar and the support body. The anti-twist security is achieved, for example, by a positive fit with correspondingly pronounced profiles between the guide sleeve and the longitudinal guide body. A square profile, also known as a square cross-section, is suitable, for example.

[0030] According to an advantageous embodiment of the invention, the contact body has a main contact plane that runs parallel to the outer web extension axis and / or the hooking web extension axis. This parallelism enables the most secure clamping of the end plate. It has been found that larger deviations from parallelism result in play in the clamping of the end plate.

[0031] Particularly preferably, the ratio of the support body's horizontal width to vertical height is between 2:1 and 5:1. This ratio is particularly preferably 4:1. This has been found to be helpful for a uniform force distribution during transport of the transport device.

[0032] In particular, the transport device is made of a single alloy. This is preferably S235JR+AR (new edition EN 10025-2:2004-10, formerly S235JRG2, even earlier St 37-2, material numbers 1.0036 to 1.0038, previously designated according to EU 25-72 also Fe 360 ​​B) or S355J2+N (new edition EN 10025-2:2004-10, formerly S355J2G3, even earlier St 52-3 N, material numbers 1.0577 or 1.0570, previously designated according to EU 25-72 also Fe 510 D1). These alloys have been shown to enable a cost-effective transport device with good mechanical properties.

[0033] The definition of perpendicular, i.e., 90 degrees, and parallel within the meaning of the invention provides for deviations of less than or equal to 10 degrees, but at least less than or equal to 5 degrees. However, complete parallelism or a precisely perpendicular angle is particularly preferred. However, this may vary depending on production.

[0034] In particular, it is intended that at least the longitudinal guide body is cut out of a sheet metal using flame, plasma, laser, or waterjet cutting. This has a stress-reducing effect.

[0035] Preferably, the hook assembly is connected monolithically to the longitudinal guide body. Monolithic means that the hook assembly and the longitudinal guide body are manufactured in a single production step. This has a stress-reducing effect.

[0036] For example, the gripping device is connected to the longitudinal guide body as a single piece. "Single piece" means that both parts can be joined together in a separate process, either detachably or permanently, using thermal joining methods, for example. This has the advantage of a secure connection.

[0037] According to an advantageous embodiment of the invention, the transport device comprises an adjusting element with a support body, wherein the adjusting element is translationally movable along the longitudinal axis of the longitudinal guide body in order to abut a front plate of the cable drum with the support body during transport of the cable drum. It is therefore advantageous that the transport device comprises a translationally movable adjusting element with a support body. The front plate of the cable drum is thus clamped between the support body and the hooking web. In particular, it is provided that a cable drum is transported by two conveyors, each with a transport device. The translational displaceability enables flexible applicability for a variety of different cable drum geometries.The adjustment element can be moved in such a way that it can be hooked into an opening in a front plate. The adjustment element is then moved translationally in such a way that a secure connection is created between the transport device and the cable drum. The adjustment element usually locks itself in place under its own weight, making the process time-efficient and reliable. No special training is required, as the transporter only has to worry about hooking it in and the subsequent transport. Furthermore, the translational moveability of the adjustment element enables flexible application with differently sized front plates. For example, projections on a front plate that would prevent the contact body from being evenly positioned can be avoided by supporting the contact body at a different location.The abutment of the end plate of the cable drum by the support body is achieved, in particular, oriented towards the axis of rotation by means of positive resistance. Furthermore, a force-fitting component can act oriented towards the axis of rotation and vertically to the axis of rotation by pressing the support body against the end plate. In order to be able to use the support body to securely abut any thickness of the cable drum during transport of the cable drum by the transport device, a flexible option must be provided. This is made possible by the translational mobility of the adjustment element. The adjustment element must therefore be adjusted to provide abutment, in particular before transport, in order to abut the end plate of the cable drum during transport of the cable drum. During transport of the cable drum, the position of the adjustment element along the longitudinal axis of the longitudinal guide body is maintained.

[0038] According to an advantageous embodiment of the invention with adjusting element it is provided that The adjustment element is continuously translationally movable along the longitudinal axis of the longitudinal guide body. This continuously adjustable design allows for ideal adaptation to the dimensions and properties of the end plate to be supported. The transport device is flexible in its application and does not need to be individually designed and selected for each cable reel. This reduces the time required to select the appropriate transport device and also reduces the costs of multiple transport devices.

[0039] According to an advantageous embodiment of the invention, it is provided that the adjusting element has a guide sleeve which guides the longitudinal guide body for the translational movement of the adjusting element along the This has proven to be a suitable option for ensuring reliable application under harsh environmental conditions. The adjustment element is thus securely mounted on the transport device and is not at risk of being lost, whether the transport device is in use or not. Preferably, there can be some play between the longitudinal guide body and the guide sleeve to allow the sliding element to drop more easily due to its weight when used against the support.

[0040] According to an advantageous embodiment of the invention, it is provided that the guide sleeve is connected to the support body at least indirectly, in particular via a spacer element, wherein the preferred spacer element is arranged along the longitudinal axis of the longitudinal guide body in the lower quarter of the guide sleeve. The spacer element has the advantage of increasing the flexibility of the transport device. In an exemplary angled design of the longitudinal guide body, the increasing distance, which promotes the safety of the conveyor, can be compensated for when the transport device is used on thin-walled cable drums. The low arrangement of the preferred spacer element enables the greatest possible distance from the gripping means when the abutment is used in the case of an angled longitudinal guide body, and thus increases the safety of the conveyor.

[0041] According to an advantageous embodiment of the invention, the contact body has a main contact plane that runs parallel to the outer web extension axis and / or the hooking web extension axis. This parallelism enables the most secure clamping of the end plate. It has been found that larger deviations from parallelism result in play in the clamping of the end plate.

[0042] According to an advantageous embodiment of the invention, the transport device comprises an adjusting element with a contact body for contacting a front plate of the cable drum, wherein the adjusting element is arranged on the longitudinal guide body in a manner secured against rotation about the longitudinal axis of the longitudinal guide body. One advantage is that the adjusting element with its contact body is arranged on the longitudinal guide body in a manner secured against rotation, also called rotationally fixed, about the longitudinal axis of the longitudinal guide body. This significantly increases the safety of the transporter, particularly in light of the need to complete work quickly, so that every professional activity of the transporter can be designed with as few risks as possible. This is achieved in this way.While an unexpected twisting of the adjustment element can cause the conveyor to lose balance during transport of the cable drum due to the weight shift of the adjusting cable drum, this risk is eliminated by the inventive, rotationally fixed design of the adjustment element. This also accelerates the hooking of the hooking bar into the opening of a face plate, thus speeding up workflows because manual readjustment is not required during each hooking process to ensure the system body is rotated as required.

[0043] According to an advantageous embodiment of the invention, the adjustment element is limited in its translational mobility along the longitudinal axis of the longitudinal guide body at the transition from the gripping means to the longitudinal guide body. This ensures that the transport operator does not suffer finger injuries due to the adjustment element possibly slipping upwards during transport of the cable drum.

[0044] According to an advantageous embodiment of the invention, the adjustment element is limited in its translational mobility along the longitudinal axis of the longitudinal guide body at the transition from the longitudinal guide body to the U-shaped hook arrangement. The deeper the displacement element is arranged, the thinner the material thickness of the end plate of the transport device. However, a thin material thickness also means that the end plate can be destroyed more quickly. Therefore, the adjustment element is preferably secured with a lower stop so that no further force can act on the end plate, which would act without a lower stop and thus destroy the material of the end plate.

[0045] According to an advantageous embodiment of the invention, the adjusting element is arranged on the longitudinal guide body in a manner that prevents it from twisting around the longitudinal axis of the longitudinal guide body via a positive locking mechanism. This positive locking mechanism is a simple technical means of ensuring that the adjusting element does not twist relative to the longitudinal guide body, thus preventing a transported cable reel from being released from its fixed position within the transport device in the event of accidental jerky movements during transport.

[0046] According to an advantageous embodiment of the invention, the adjustment element has a guide sleeve that surrounds the longitudinal guide body for translational movement of the adjustment element along the longitudinal axis. This has the advantage that the adjustment element is mounted on the longitudinal guide body in a way that prevents it from being lost. Thus, the adjustment element cannot be lost during construction, and occupational safety can always be guaranteed.

[0047] According to an advantageous embodiment of the invention, the longitudinal guide body has a non-circular cross-section, in particular a square cross-section, in cross-section relative to its longitudinal axis of extension, and the adjusting element has a guide sleeve that encloses the longitudinal guide body with a corresponding inner hollow cross-section, in particular an inner square hollow cross-section. This is a particularly preferred embodiment and an advantageous example of a positive locking mechanism. In particular, this simultaneously enables cost-effective production and also secure abutment.

[0048] According to an advantageous embodiment of the invention, the square cross-section has a respective edge length of 8 millimeters up to and including 12 millimeters, preferably up to and including 10 millimeters, wherein the inner square hollow cross-section of the guide sleeve has a respective edge length as internal dimensions for enclosing the square cross-section, including 0.5 millimeters up to and including 3 millimeters, preferably up to and including 1 millimeter, greater than the respective edge length of the square cross-section. The longitudinal guide body is thus held somewhat loosely in the guide sleeve. This has the advantage that even the finest dirt particles do not clog the guide sleeve around the longitudinal guide body, so that the conveyor falsely assumes a fixed abutment.There's a risk that these dirt particles could become dislodged during transport, causing the guide sleeve to slip, and ultimately causing the cable reel to fall due to the shock load. This risk can be mitigated by providing sufficient clearance.

[0049] According to an advantageous embodiment of the invention, the contact body is deburred at least at its edges for contact with the end plate, preferably at all edges. This helps prevent the contact body from accidentally jamming against the end plate. This jamming could potentially come loose during transport of the cable reel, causing the guide sleeve to slip, and ultimately causing the cable reel to fall due to the impact load. This risk can be reduced by providing appropriate clearance.

[0050] According to an advantageous embodiment of the invention, the end section of the hooking bar is flat or has a cover, in particular a rubber cover, to prevent damage to the hollow cylinder from the inside. Unexpected damage to the hollow cylinder from the inside would cause the cable drum to sag, thus increasing the risk of injury to the conveyor operator. This is now eliminated.

[0051] According to an advantageous embodiment of the invention, the gripping means has a round cross-section for gripping. This facilitates gripping of the gripping means and thus reduces the risk of the handle coming loose during transport of the cable reel, for example, due to edges pressing into the fingers. In particular, the longitudinal guide body can have a polygonal cross-section. A polygonal cross-section, for example, a square cross-section, enables a rotation-proof arrangement of an adjusting element and also provides an advantageous force flow when subjected to loads due to the weight of the cable reel.

[0052] The transport device is used to transport the cable reel, in particular together with a second transport device, with each transport device being individually hooked into an opening in the cable reel by a human transport operator. The operators can thus each transport the cable reel with one hand.

[0053] The invention will be explained below by way of example with reference to the accompanying drawings using preferred embodiments, wherein the features presented below can represent an aspect of the invention both individually and in combination. They show: Fig. 1: a perspective view of a preferred embodiment of a transport device with an adjusting element pushed downwards along a longitudinal axis of a longitudinal guide body, Fig. 2: a perspective view of the transport device according to Fig. 1 with an adjusting element pushed upwards along the longitudinal axis of the longitudinal guide body, Fig. 3: a front view of the transport device according to Fig. 1 with an adjusting element pushed upwards along the longitudinal axis of the longitudinal guide body, Fig. 4: a rear view of the transport device after Fig. 1 with an adjusting element pushed upwards along the longitudinal axis of the longitudinal guide body, Fig. 5: another perspective view of the transport device according to Fig. 1 with an adjusting element pushed upwards along the longitudinal axis of the longitudinal guide body, Fig. 6: a side view of the transport device according to Fig. 1 as a section with an adjustment element pushed downwards along the longitudinal axis of the longitudinal guide body and with schematically shown angles, Fig. 7: another perspective view of the transport device according to Fig. 1 as a cutout with an adjustment element pushed downwards along the longitudinal axis of the longitudinal guide body, Fig. 8: another perspective view of the transport device according to Fig. 1 as a cutout with an adjustment element pushed downwards along the longitudinal axis of the longitudinal guide body, Fig. 9: a front view of an empty cable reel during its transport, wherein the cable reel is transported by two conveyors, each with a preferred transport device, and Fig. 10: a perspective view of the cable reel transported by the two transport devices according to Fig. 9 as an excerpt.

[0054] Fig. 1 shows a transport device 10 for transporting a cable drum 12 with a central bore 13 and a rotation axis D. For this purpose, the transport device 10 has - a gripping means 14 for gripping by a user during transport of the cable reel 12, - a longitudinal guide body 16 arranged on the gripping means 14 with a longitudinal axis L, and - a U-shaped hook arrangement 18 arranged on the longitudinal guide body 16 for hooking into the central bore 13 of the cable drum 12, wherein the hook arrangement 18 has an outer web 20 with an outer web extension axis A, a load web 22 and a hooking web 24 with a hooking web extension axis E, wherein the hooking web 24 is designed for abutment on the cable drum 12.

[0055] The longitudinal extension axis L of the longitudinal guide body 16 and the outer web extension axis A of the outer web 20 are arranged at an acute angle α to each other.

[0056] In all Fig. Figures 1 to 10 illustrate a single embodiment by way of example. The following describes an advantageous embodiment using consistent terminology. Optional embodiments are not limiting and are not entirely binding for the explicit embodiment.

[0057] The transport device 10 is intended in particular for transporting the cable drum 12. Preferably, its suitability is also extended to lifting and setting down the cable drum 12. Suitability for lifting, transporting, and setting down is then understood as conveying.
