A pallet sled includes a lower frame and an upper frame. A plurality of pivot arms pivotably connect the upper frame to the lower frame. The upper frame is movable between a lowered position and raised position. The upper frame is spaced further from the lower frame in the raised position than in the lowered position. The upper frame is rotated slightly relative to the lower frame when moved from the lowered position to the raised position. In the example embodiment, the upper frame is rotated approximately 1.5 degrees to approximately 2.0 degrees toward the upright handle of the pallet sled.

A pallet jack assembly for use with a pallet jack is provided. The pallet jack assembly includes a tug assembly configured for attachment to a towing vehicle and a frame assembly configured to support the tug assembly. A plurality of caster assemblies is supported by the frame assembly. Each of the caster assemblies is configured to support a wheel. The pallet jack assembly facilitates use of the pallet jack as a hand-powered pallet jack or for towing by a towing vehicle.

A drive unit includes a drive wheel, a prime mover, a coupling mechanism and a support frame. The coupling mechanism includes first and second coupling members. The first coupling member includes a first opposed surface. The second coupling member includes a second opposed surface opposed to the first opposed surface. The second coupling member is attached to the first coupling member in a detachable manner. The support frame is attached to the coupling mechanism. The support frame supports the drive wheel and the prime mover. The first coupling member includes a first vertical groove and a first transverse groove on the first opposed surface. The second coupling member includes a second vertical groove and a second transverse groove on the second opposed surface. The second vertical groove is opposed to the first vertical groove. The second transverse groove is opposed to the first transverse groove.

A drive unit includes a support frame, a drive wheel and a prime mover. The support frame is disposed to be pivotable about a pivot axis. The drive wheel is supported by the support frame. The prime mover is supported by the support frame. The prime mover drives the drive wheel. The support frame and at least one member form a pivot unit. The at least one member pivots together with the support frame. The pivot unit has a center of gravity disposed on the opposite side of the pivot axis with respect to the drive wheel.

A pallet truck comprises a rolling frame (10) and at least one force sensor (51, 52) for registering and generating as electronic output signal a loading of a load platform (20). The force sensor is coupled to electronic processing means for receiving and processing the output signal, and display means (65) are provided for generating a visual weight indication. At least a part of the processing means is accommodated together with a first electronic power supply in a first housing (50) forming part of the frame (10). The display means (65) are arranged together with a second electronic power supply in a second housing (60) on or close to a handle (45) of an operating arm. A wired first connection (56) is provided between the force sensor (51, 52) and the processing means. Telecommunication means are provided for establishing and maintaining a wireless second connection (57) between the first housing (50) and the second housing (60).

A pneumatic cylinder actuated pallet jack assembly for mechanically lifting and lower a pallet includes a pallet jack, a plurality of pneumatic cylinders, and a compressor. The forks of the pallet jack are slidably coupled to a frame of the pallet jack. Each of a pair of rear rollers that is coupled to a respective fork distal from the frame and a roller module that is slidably coupled to the frame are selectively vertically positionable. A tow bar is pivotally coupled to the frame proximate to the roller module. Pneumatic cylinders are operationally coupled singly to each of the forks, the pair of rear rollers, and to the roller module, and the compressor. The compressor is positioned to selectively actuate respective pneumatic cylinders to size a gap between the forks and to raise the forks and the frame to lift a load that is positioned on the pallet.

The present disclosure is related to an electric pallet truck. The electric pallet truck includes a frame, a lifting unit, and a walking unit. The lifting unit is configured to adjust a height of the frame. The walking unit is configured to drive the frame to move. The lifting unit includes a lifting mechanism fixedly connected to the frame and a hydraulic mechanism configured to control a lifting of the lifting mechanism. The walking unit includes a driving mechanism configured at a bottom of the lifting mechanism.

A pallet truck has a pressed and non-welded fork structure. The fork structure includes an elongate body portion and an outboard end portion integrally formed with the body portion. The body portion has a top wall and opposing sidewalls integrally formed with the top wall. The outboard end portion projects from the body portion and includes a tip sidewall defining a tip region for guiding entry of a fork assembly beneath a pallet.

Disclosed is an industrial vehicle, which includes a handle (32), a main vehicle frame (2), and a drive wheel assembly (33), a vertical column (1) being mounted on the main vehicle frame (2), the vertical column (1) comprising an upper top plate (11) and a back plate (13) connected to the upper top plate (11); the industrial vehicle also includes a controller (52), a pump station (53), and a jacking device (51) that abuts against the upper top plate (11); in the horizontal direction, the jacking device (51) is farther from the handle (32) than the drive wheel assembly (33). The foregoing industrial vehicle has high stability and stable lifting, optimizes the positional relationships of each component of the vehicle, and has a shorter vehicle body, such that a smaller turning radius is thus obtained.

A pallet truck includes a front frame having at least one fork and being connected to a drive unit through a lift cylinder, a plug-in battery assembly, a hydraulic supply system and a plug-in controller assembly connected to the front frame, and an operator handle connected to the drive unit. The pallet truck may include a rear frame having caster wheel assemblies that are mounted from above, and where the rear frame is connected to the drive unit.
