Description

Technical Field

[0001] This application relates to the field of clamping technology, specifically to forklift rotating clamps. Background Technology

[0002] Currently, forklifts are key equipment in the industrial material handling field. When handling goods, most existing forklifts first use the forks installed at the front of the vehicle to clamp the goods, and then move the vehicle body to carry the clamped goods to the destination in sync, thus completing the handling operation.

[0003] However, most existing forklifts clamp goods by driving the two forks together horizontally. However, the position of some goods before they are moved may not be compatible with the clamping action of the forks. This usually requires manual adjustment of the position of the goods during handling until the adjusted position of the goods is compatible with the clamping action of the forks. This will lead to an increase in overall operation time and low efficiency. Utility Model Content

[0024] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0025] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figures 1 to 4 A preferred embodiment of the forklift swivel clamp according to this application will be described in detail below. The forklift swivel clamp is used to be mounted on a vehicle body, and the forklift swivel clamp includes a mounting body 10, an adjustment device 20 and a clamping assembly 30.

[0028] Specifically, the adjustment device 20 includes a first adjustment component 21, wherein the first adjustment component 21 includes a first adjustment drive 211 and a first driving member 212. The first adjustment drive 211 is installed on the installation body 10, and the first driving member 212 is synchronously rotatably connected to the first adjustment drive 211.

[0029] The clamping assembly 30 includes a first clamping arm 31 and a second clamping arm 32, wherein one end of the first clamping arm 31 is mounted on the first driving member 212, and the first clamping arm 31 and the second clamping arm 32 are both disposed at the front end of the mounting body 10, and a clamping opening 301 is formed between the second clamping arm 32 and the first clamping arm 31 for clamping goods.

[0030] When the first adjustment drive 211 drives the first drive member 212 to rotate relative to the mounting body 10, the first clamping arm 31 is driven to rotate relative to the second clamping arm 32, so that the distance between the first clamping arm 31 and the second clamping arm 32 is adjusted, thereby adjusting the opening size of the clamping mouth 301.

[0031] Those skilled in the art will understand that when the first clamping arm 31 and the second clamping arm 32 need to be used for clamping operations, the first adjustment drive 211 is activated to drive the first driving member 212 to drive the first clamping arm 31 to rotate relative to the second clamping arm 32, so as to adjust the size of the opening of the clamping mouth 301 formed between the first clamping arm 31 and the second clamping arm 32, so that the size of the opening of the clamping mouth 301 is adjusted to gradually adapt to the current placement size of the goods. At this time, the inner wall of the first clamping arm 31 forming the clamping mouth 301 and the inner wall of the second clamping arm 32 forming the clamping mouth 301 also gradually abut against the surface of the goods, thereby clamping the goods.

[0032] Thus, by adjusting the position of the first clamping arm 31 so that the first clamping arm 31 moves to a different position on the surface of the goods when clamping the goods with the second clamping arm 32, and cooperates with the second clamping arm 32 to clamp the goods, the step of manually adjusting the position of the goods to cooperate with the clamping action is omitted, thereby improving clamping efficiency.

[0033] Preferably, such as Figure 3 and Figure 4 As shown, the positioning device 20 further includes a second positioning assembly 22, wherein the second positioning assembly 22 includes a second positioning drive member 221 and a second driving member 222. The second positioning drive member 221 is mounted on the mounting body 10, and the second driving member 222 is rotatably connected to the second positioning drive member 221. One end of the second clamping arm 32 is mounted on the second driving member 222, and when the second positioning drive member 221 drives the second driving member 222 to rotate relative to the mounting body 10, the second clamping arm 32 is driven to rotate relative to the first clamping arm 31, so that the distance between the first clamping arm 31 and the second clamping arm 32 is adjusted, thereby adjusting the opening size of the clamping jaw 301.

[0034] In one embodiment, such as Figure 4 As shown, the first driving member 212 includes a first driving member 2121, a first passive member 2122, and a first supply block 2123. The first driving member 2121 is synchronously rotatably connected to the first adjusting driving member 211, and the other end of the first driving member 2121 away from the first adjusting driving member 211 is connected to the first passive member 2122, forming a predetermined angle with it. An L-shaped structure is formed between the first driving member 2121 and the first passive member 2122. The first supply block 2123 is connected to the other end of the first passive member 2122 away from the first driving member 2121. The first clamping arm 31 is mounted on the first supply block 2123.

[0035] It is understood that when the first adjustment drive member 211 drives the first driving member 2121 to rotate, the first passive member 2122 is driven synchronously and rotates around the predetermined position where the first driving member 2121 is connected to the first adjustment drive member 211. Since the first driving member 2121 and the first passive member 2122 form the L-shaped structure, the first transfer block 2123 connected to the first passive member 2122 also rotates around the predetermined position where the first driving member 2121 is connected to the first adjustment drive member 211, so that the first clamping arm 31 is driven to rotate. Then, when the first clamping arm 31 and the second clamping arm 32 are used for clamping operation, the first clamping arm 31 rotates relative to the second clamping arm 32 by the first adjustment drive member 211 driving the first driving member 212 to rotate, so that the opening size of the clamping jaw 301 is adjusted.

[0036] Preferably, the first driving member 2121 and the first passive member 2122 are each configured as a transmission shaft.

[0037] It is worth mentioning that, in a modified embodiment, the first driving member 2121 and the first passive member 2122 in the first driving member 212 are configured as an integrally formed L-shaped structure, wherein one end of the L-shaped structure is connected to the first adjusting driving member 211, and the other end of the L-shaped structure is connected to the first shifting block 2123 in the first driving member 212.

[0038] In one embodiment, such as Figure 4As shown, the second driving member 222 includes a second driving member 2221, a second passive member 2222, and a second supply block 2223. The second driving member 2221 is synchronously rotatably connected to the second adjusting driving member 221, and the other end of the second driving member 2221 away from the second adjusting driving member 221 is connected to the second passive member 2222, forming a predetermined angle with the second passive member 2222. An L-shaped structure is formed between the second driving member 2221 and the second passive member 2222. The second supply block 2223 is connected to the other end of the second passive member 2222 away from the second driving member 2221. The second clamping arm 32 is mounted on the second supply block 2223.

[0039] It is understood that when the second adjustment drive member 221 drives the second driving member 2221 to rotate, the second passive member 2222 is driven synchronously and rotates around the predetermined position where the second driving member 2221 and the second adjustment drive member 221 are connected. Since the second driving member 2221 and the second passive member 2222 form the L-shaped structure, the second transfer block 2223 connected to the second passive member 2222 also rotates around the predetermined position where the second driving member 2221 and the second adjustment drive member 221 are connected, so that the second clamping arm 32 is driven to rotate. Then, when the second clamping arm 32 is used for clamping operation, the second clamping arm 32 rotates relative to the second clamping arm 32 by the second adjustment drive member 221 driving the second driving member 222 to rotate, so that the opening size of the clamping jaw 301 is adjusted.

[0040] Preferably, the second driving member 2221 and the second passive member 2222 are each configured as a transmission shaft.

[0041] It is worth mentioning that, in a modified embodiment, the second driving member 2221 and the second passive member 2222 in the second driving member 222 are configured as an integrally formed L-shaped structure, wherein one end of the L-shaped structure is connected to the second adjustment driving member 221, and the other end of the L-shaped structure is connected to the second supply and transfer block 2223 in the second driving member 222.

[0042] Preferably, such as Figure 3As shown, the mounting body 10 has an internal mounting space 101 and an arc-shaped opening 102 communicating with the mounting space 101. The arc-shaped opening 102 is formed at the front end of the mounting body 10 and is arc-shaped. The first adjustment drive member 211 and the second adjustment drive member 221 are both disposed in the mounting space 101, and the first adjustment drive member 211 and the second adjustment drive member 221 are evenly and spaced apart along the axial direction of the mounting body 10. The other end of the first passive member 2122, away from the first driving member 2121, is disposed extending from the mounting space 101 of the mounting body 10 towards the arc-shaped opening 102 until it passes through the arc-shaped opening 102 and is located outside the mounting body 10, so as to connect with the first moving block 2123. The other end of the second passive member 2222, away from the second driving member 2221, is provided to extend from the mounting space 101 of the mounting body 10 toward the arcuate opening 102 until it passes through the arcuate opening 102 and is located outside the mounting body 10, so as to connect with the second transfer block 2223.

[0043] More preferably, the rear end of the mounting body 10 also has a mounting part 11, and the mounting body 10 also has at least one connecting hole 103 on the mounting part 11 for connecting with the vehicle body.

[0044] As a further preferred embodiment, each of the connecting holes 103 is configured as a threaded hole.

[0045] In another embodiment, such as Figure 5 and Figure 6As shown, the mounting body 10 is provided with a rotating shaft 12 inside the mounting space 101, and the first driving component 212 includes a first driving component 2121, a first passive component 2122 and a first moving block 2123, wherein the first driving component 2121 is synchronously rotatably connected to the first adjusting driving component 211. The first passive member 2122 is configured as a semi-circle and is rotatably connected to the feed shaft 12. In a cross-section perpendicular to the axis of the feed shaft 12, the two perpendicular distances between any two points on the arc edge of the first passive member 2122 and the center of the feed shaft 12 are equal. The first driving member 2121 is rollably engaged with the toothed groove at the arc edge of the first passive member 2122. Therefore, when the first adjusting drive member 211 drives the first driving member 2121 to rotate, the first passive member 2122 is driven, which in turn drives the first feed block 2123 to rotate relative to the feed shaft 12. This causes the first clamping arm 31 to rotate about the feed shaft 12, moving closer to and further away from the second clamping arm 32, thereby adjusting the opening size of the clamping jaw 301. It is worth noting that in this embodiment, the first driving member 2121 is configured as a gear. The first passive member 2122 is configured as a semi-circular gear structure.

[0046] Furthermore, such as Figure 5 and Figure 6 As shown, the second driving member 222 includes a second driving member 2221, a second passive member 2222 and a second shifting block 2223, wherein the second driving member 2221 is synchronously rotatably connected to the second adjusting driving member 221. The second passive member 2222 is configured as a semi-circle and is rotatably connected to the feed shaft 12, maintaining a distance from the first passive member 2122. In a cross-section perpendicular to the axis of the feed shaft 12, the two perpendicular distances between any two points on the arc edge of the second passive member 2222 and the center of the feed shaft 12 are equal. The second driving member 2221 is rollably engaged with the toothed groove at the arc edge of the second passive member 2222. Therefore, when the second adjusting drive member 221 drives the second driving member 2221 to rotate, the second passive member 2222 is driven, causing the second feed block 2223 to rotate relative to the feed shaft 12. This causes the second clamping arm 32 to rotate about the feed shaft 12, moving closer to and further away from the first clamping arm 31, thereby adjusting the opening size of the clamping jaw 301. It is worth noting that in this embodiment, the second driving member 2221 is configured as a gear. The second passive element 2222 is configured as a semi-circular gear structure.

[0047] Preferably, the first adjustment drive 211 is implemented as a hydraulic motor, and the second adjustment drive 221 is also implemented as a hydraulic motor.

[0048] Thus, when activating the first adjustment drive 211 alone is insufficient to stably clamp the goods by the first clamping arm 31 and the second clamping arm 32, the first adjustment drive 211 and the second adjustment drive 221 can be activated simultaneously to drive the first driving member 212 and the second driving member 222 respectively. This causes the first clamping arm 31 and the second clamping arm 32 to move along the forming direction of the arc-shaped opening 102 to a predetermined position where the goods can be stably clamped.

[0049] It should be added that when the first clamping arm 31 and the second clamping arm 32 have clamped the goods, by synchronously activating the two first adjustment drive units 211, the first clamping arm 31 and the second clamping arm 32 move simultaneously along the forming direction of the arc-shaped opening 102, so that the goods clamped by the first clamping arm 31 and the second clamping arm 32 also move along the forming direction of the arc-shaped opening 102 and gradually adjust their position, thereby facilitating the subsequent release operation of the goods.

[0050] Furthermore, the clamping assembly 30 also includes a first clamping drive unit 33, the first clamping arm 31 is driven and movably connected to the first clamping drive unit 33, and when the first clamping drive unit 33 drives the first clamping arm 31 to move, the first clamping arm 31 is configured to move relatively closer to and further away from the second clamping arm 32, so as to further adjust the opening size of the clamping jaw 301 between the first clamping arm 31 and the second clamping arm 32.

[0051] In one embodiment, the first clamping drive unit 33 is configured as a hydraulic cylinder, which is connected to the first transfer block 2123 and has a telescopic end. The first clamping arm 31 is connected to the telescopic end of the hydraulic cylinder. When the hydraulic cylinder is activated to extend or retract the telescopic end, the first clamping arm 31 moves with the telescopic end to move closer to and away from the second clamping arm 32.

[0052] In another embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the first clamping drive unit 33 includes a first clamping drive member 331 and a first transmission member 332. The first clamping drive member 331 is mounted on the first transfer block 2123 and is used to drive the first transmission member 332. The first clamping arm 31 is connected to the first transmission member 332, and the first transmission member 332 is driven by the first clamping drive member 331 to move the first clamping arm 31 relatively closer to and away from the second clamping arm 32, thereby adjusting the opening size of the clamping jaw 301.

[0053] Preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, the first transmission component 332 includes a first screw 3321 and a first slider 3322. The first screw 3321 is rotatably connected to the first clamping drive 331, and the first screw 3321 passes through the first slider 3322 and is threadedly connected to the first slider 3322. The first slider 3322 is movably connected to one side of the first transfer block 2123, and the first clamping arm 31 is connected to the first slider 3322. When the first clamping drive 331 drives the first screw 3321 to rotate, the first slider 3322 is driven to move to one side of the first transfer block 2123 due to the abutment action of the first transfer block 2123, so that the first clamping arm 31 is relatively moved closer to and away from the second clamping arm 32, thereby adjusting the opening size of the clamping jaw 301.

[0054] Therefore, when it is necessary to further clamp a cargo by the clamping assembly 30, the first clamping arm 31 is moved by driving the first transmission member 332 through the first clamping drive member 331 to adjust the opening size of the clamping jaw 301 until the opening size of the clamping jaw 301 is adapted to the size of the cargo.

[0055] Furthermore, the clamping assembly 30 also includes a second clamping drive unit 34. The second clamping arm 32 is driven and movably connected to the second clamping drive unit 34. When the second clamping drive unit 34 drives the second clamping arm 32 to move, the second clamping arm 32 is configured to move relatively closer to and further away from the first clamping arm 31, so as to further adjust the opening size of the clamping jaw 301 between the first clamping arm 31 and the second clamping arm 32, and at the same time, further shorten the time required for the goods to be clamped.

[0056] In one embodiment, the second clamping drive unit 34 is configured as a hydraulic cylinder connected to the second feed block 2223, and the hydraulic cylinder has a telescopic end. The second clamping arm 32 is connected to the telescopic end of the hydraulic cylinder. When the hydraulic cylinder is activated to extend or retract the telescopic end, the second clamping arm 32 moves with the telescopic end to move closer to and away from the first clamping arm 31.

[0057] In another embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the second clamping drive unit 34 includes a second clamping drive member 341 and a second transmission member 342. The second clamping drive member 341 is mounted on the second transfer block 2223 and is used to drive the second transmission member 342. The second clamping arm 32 is connected to the second transmission member 342, and the second transmission member 342 is driven by the second clamping drive member 341 to move the second clamping arm 32 relatively closer to and away from the first clamping arm 31, thereby adjusting the opening size of the clamping jaw 301.

[0058] Preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, the second transmission component 342 includes a second screw 3421 and a second slider 3422. The second screw 3421 is rotatably connected to the second clamping drive 341, and the second screw 3421 passes through the second slider 3422 and is threadedly connected to the second slider 3422. The second slider 3422 is movably connected to one side of the second transfer block 2223, and the second clamping arm 32 is connected to the second slider 3422. When the second clamping drive 341 drives the second screw 3421 to rotate, the second slider 3422 is driven to move to one side of the second transfer block 2223 due to the abutment action of the second transfer block 2223. This causes the second clamping arm 32 to move relatively closer to and away from the first clamping arm 31, thereby adjusting the opening size of the clamping jaw 301.

[0059] More preferably, such as Figure 1 , Figure 2 and Figure 4As shown, the first transfer block 2123 forms at least one first guide rail 21231, and the first clamping arm 31 forms at least one first guide channel 3101 on the side near the first transfer block 2123. One first guide rail 21231 is correspondingly disposed in one first guide channel 3101, and the first clamping arm 31 is slidably mounted on at least one first guide rail 21231 of the first transfer block 2123 via at least one first guide channel 3101. Thus, when the first clamping arm 31 is driven by the first clamping drive unit 33, the first clamping arm 31 moves closer to and away from the second clamping arm 32 along the extension direction of at least one first guide rail 21231, so that the opening size of the clamping jaw 301 is adjusted. At the same time, since one first guide rail 21231 is correspondingly disposed in one first guide channel 3101, the first clamping arm 31 is less likely to deviate during movement.

[0060] More preferably, the first clamping arm 31 is provided with at least one first guide portion 311, and a first guide channel 3101 is provided on one side of the first guide portion 311.

[0061] It is worth mentioning that, as a variation, the first supply block 2123 is configured to form at least one limiting groove, and the first clamping arm 31 forms at least one limiting protrusion, and one limiting protrusion is correspondingly provided with one limiting groove. The first clamping arm 31 is slidably mounted on at least one limiting groove of the first supply block 2123 through at least one limiting protrusion. That is, the first clamping arm 31 can also move relatively closer to and away from the second clamping arm 32 under the driving action of the first clamping drive unit 33 to adjust the opening size of the clamping jaw 301.

[0062] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the first transfer block 2123 forms two first guide rails 21231, and the two first guide rails 21231 are arranged opposite to each other and spaced apart. The first clamping arm 31 correspondingly forms two first guide channels 3101. That is, the first clamping arm 31 is slidably mounted on the two first guide rails 21231 of the first transfer block 2123 through the two first guide channels 3101.

[0063] It is understandable that as the number of the first guide rails 21231 on the first feed block 2123 and the number of the first guide channels 3101 on the first clamping arm 31 increase accordingly, the first clamping arm 31 moves more and more stably relative to the first feed block 2123 by means of the driving action of the first clamping drive unit 33.

[0064] More preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, the second transfer block 2223 forms at least one second guide rail 22231, and the second clamping arm 32 forms at least one second guide channel 3201 on the side near the second transfer block 2223. One second guide rail 22231 is correspondingly disposed in one second guide channel 3201, and the second clamping arm 32 is slidably mounted on at least one second guide rail 22231 of the second transfer block 2223 via at least one second guide channel 3201. Thus, when the second clamping arm 32 is driven by the second clamping drive unit 34, the second clamping arm 32 moves closer to and away from the second clamping arm 32 along the extension direction of at least one second guide rail 22231, so that the opening size of the clamping jaw 301 is adjusted. At the same time, since one second guide rail 22231 is correspondingly disposed in one second guide channel 3201, the second clamping arm 32 is less likely to deviate during movement.

[0065] More preferably, the second clamping arm 32 is provided with at least one second guide portion 321, and a second guide channel 3201 is provided formed on one side of the second guide portion 321.

[0066] It is worth mentioning that, as a variation, the second feed block 2223 is configured to form at least one limiting channel, and the second clamping arm 32 forms at least one of the limiting protrusions, with one limiting protrusion corresponding to one limiting channel. The second clamping arm 32 is slidably mounted on at least one limiting channel of the second feed block 2223 via at least one of the limiting protrusions. That is, the second clamping arm 32 can also move relatively closer to and away from the second clamping arm 32 under the driving action of the second clamping drive unit 34 to adjust the opening size of the clamping jaw 301.

[0067] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the second transfer block 2223 forms two second guide rails 22231, and the two second guide rails 22231 are arranged opposite to each other and spaced apart. The second clamping arm 32 correspondingly forms two second guide channels 3201. That is, the second clamping arm 32 is slidably mounted on the two second guide rails 22231 of the second transfer block 2223 through the two second guide channels 3201.

[0068] It is understood that as the number of the second guide rails 22231 on a second feed block 2223 and the number of the second guide channels 3201 on the second clamping arm 32 increase accordingly, the second clamping arm 32 moves more and more stably relative to the second feed block 2223 by means of the driving action of the second clamping drive unit 34.

[0069] Preferably, the first clamping arm 31 has a first vertical portion 312 and a first horizontal portion 313 formed at one end of the first vertical portion 312. Preferably, the first vertical portion 312 extends vertically, and the first horizontal portion 313 extends horizontally, such that the first vertical portion 312 and the first horizontal portion 313 form an included angle of a predetermined size. The first guide portion 311 is uniformly formed on the first vertical portion 312.

[0070] Preferably, the second clamping arm 32 has a second vertical portion 322 and a second horizontal portion 323 formed at one end of the second vertical portion 322. Preferably, the second vertical portion 322 extends vertically, and the second horizontal portion 323 extends horizontally, such that the second vertical portion 322 and the second horizontal portion 323 form an included angle of a predetermined size. The second guide portion 321 is uniformly formed on the second vertical portion 322.

[0071] The clamping opening 301 is formed between the first horizontal portion 313 and the second horizontal portion 323. That is, when the first clamping drive 331 and the second clamping drive 341 are activated simultaneously, the first horizontal portion 313 and the second horizontal portion 323 move closer and further apart relative to each other to adjust the size of the clamping opening 301 for clamping goods.

[0072] More preferably, the first clamping arm 31 also forms a first anti-slip structure 314, which is disposed on the periphery of the first horizontal portion 313 and located in the clamping opening 301.

[0073] Correspondingly, the second clamping arm 32 also forms a second anti-slip structure 324. The second anti-slip structure 324 is disposed on the periphery of the second horizontal portion 323 and located in the clamping opening 301. Thus, when the first horizontal portion 313 and the second horizontal portion 323 are used to clamp the goods, the first anti-slip structure 314 and the second anti-slip structure 324 act on the surface of the goods to prevent the goods from sliding during the clamping process.

[0074] It is understood that the first anti-slip structure 314 is configured to consist of multiple fine lines, and the second anti-slip structure 324 is also configured to consist of multiple fine lines.

[0075] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the first clamping arm 31 forms a first guide slope 315 near the end of the first horizontal portion 313 away from the first vertical portion 312. The first guide slope 315 has a first inclined surface facing upward, and the vertical height of the first inclined surface gradually increases from the direction close to the first vertical portion 312.

[0076] Correspondingly, the second clamping arm 32 forms a second guide slope 325 near the end of the second horizontal portion 323 away from the second vertical portion 322. The second guide slope 325 has a second inclined surface facing upward, and the vertical height of the second inclined surface gradually increases from the direction close to the second vertical portion 322.

[0077] It should be noted that by simultaneously activating the first adjustment drive 211 and the second adjustment drive 221, the positions of the first clamping arm 31 and the second clamping arm 32 are gradually adjusted until the first horizontal portion 313 of the first clamping arm 31 and the second horizontal portion 323 of the second clamping arm 32 are kept spaced apart and parallel on the same plane. In this way, the first guide slope 315 of the first clamping arm 31 and the second guide slope 325 of the second clamping arm 32 are used to guide the goods to be synchronously transferred to the top surface of the first horizontal portion 313 and the top surface of the second horizontal portion 323, so that the goods are transported in a supported manner.

[0078] In other words, the forklift rotating clamp can be used for cargo handling operations not only by clamping the cargo, but also by supporting the cargo.
