The disclosure provides pallet trucks having a selective turning radius. The pallet trucks include load wheel systems having at least two load wheel assemblies below each fork. A forward load wheel assembly is located near the forward end of the fork and a central load wheel assembly is located near the center of a central portion of the fork. A first turning radius is defined by the distance between the forward load wheel assembly and a directionally adjustable rear wheel when the forward load wheel assembly supports the fork. The central load wheel assembly may be selectively deployed to lift and support the fork to yield a second, shorter turning radius defined by the distance between the central load wheel assembly and the directionally adjustable rear wheel.

In one example, a pallet jack cap system includes a stabilization outrigger secured around steer wheels of a pallet jack, a bonnet in an elevated position over forks of the pallet jack, an anchor base for attachment to the pallet jack, and a vertical extension system between the anchor base and the bonnet. The vertical extension system supports the bonnet in the elevated position over the forks of the pallet jack. The vertical extension system can include an elevating vertical support assembly, an elastic counterpoise to assist with positioning the bonnet at a particular elevation based on an extension of the vertical support assembly, and an extension lock to secure the vertical support assembly at the particular elevation. The bonnet can be lowered down over a unit load on a pallet transported by the pallet jack, to secure the unit load and items in transport by the pallet jack.

A paint cart having a base having wheels and a lifting mechanism to hold and raise a bucket of paint thereon off the floor. The paint cart may include a top platform attached to the base for holding tools and other materials and a hydraulic cylinder which prevents the lifting mechanism from lowering too abruptly.

A drive belt assembly for a load handling device includes a drive belt; a drive wheel; and one or more driven wheels. A first tensioning arm, having a fixed end above an elbow and a rotatable distal end pivotally attached at the elbow, is horizontally displaceable relative to the drive wheel and driven wheels. A second tensioning arm is provided wherein the drive belt is routed around the first and second tensioning arms, and the first and second tensioning arms are arranged to put pressure on the drive belt to tension the drive belt.

A pallet sled includes a lower frame and a plurality of wheels supporting the lower frame. An upper frame is configured to support a pallet thereon. A ratchet is configured to lift the upper frame relative to the lower frame. A handle is configured to operate the ratchet to lift the upper frame relative to the lower frame. The handle may be pivotable relative to the lower frame. The ratchet may include a gear and a pawl. The ratchet may also be configured to selectively lower the upper frame. As another option, one or more of the handle, the upper frame or the plurality of wheels are reconfigurable between an extended position and a retracted position.

A load handling device is disclosed for lifting and moving storage containers stacked in a grid framework structure having first and second sets of parallel rails or tracks. The load handling device includes: a body mounted on first and second sets of wheels arranged to engage with the tracks. A direction-change assembly is arranged to raise or lower the first set of wheels and or lower or raise the second set of wheels with respect to the body to engage and disengage the wheels with the tracks. The direction-change assembly includes a linkage-set having a series of members arranged between a traveller and a fixed brace, wherein the traveller is arranged to move under an applied force to cause the wheels to raise or lower.

A modular fork assembly for a pallet truck includes a discrete elongate body, a discrete load wheel module, and a discrete fork tip that may be detachably connected by the same or different types of interlocking mechanisms that are adapted to inhibit sheer forces. The load wheel module includes a frame and a load wheel assembly that includes a load wheel that is operatively connected to the frame.

A pallet sled includes a pair of tines extending forward from a base. A load wheel supports each of the pair of tines. The load wheels are each configured to move away from the respective tine to lift the respective tine upward relative to a support surface on which the load wheel is supported. A processor on the pallet sled records usage of the sled, such as lift cycles, location over time, battery condition, lift height, weight lifted, distance traveled, and the like. A communication circuit may be configured to send data from the pallet sled to a remote server. An identification reader may be configured to read an identification tag of an object supported on the pair of tines, such as an rfid tag on a pallet.

A vehicle system includes a first vehicle and a second vehicle. The first vehicle includes a first drive motor configured to drive one or more of a first plurality of tractive elements to propel the first vehicle, and a first cradle configured to support a product at a first end thereof for movement. The second vehicle includes a second drive motor configured to drive one or more of a second plurality of tractive elements to propel the second vehicle, and a second cradle configured to support the product at a second end thereof for movement. The first vehicle and the second vehicle move the product via at least one of the first drive motor or the second drive motor.

A vehicle coupling system includes a first vehicle, a second vehicle, and a tow bar. The first vehicle includes a drive motor configured to propel the first vehicle and a lifting implement configured to support a product for movement. The second vehicle includes a lifting implement configured to support the product for movement. The tow bar is coupled to the first vehicle at a first end of the tow bar and coupled to the second vehicle at a second end of the tow bar opposite the first end. Responsive to the drive motor propelling the first vehicle, the tow bar exerts a force on the second vehicle to maintain a space between the second vehicle and the first vehicle.
