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.

Cap system for pallet jack

An electric pallet jack can be configured to include logic controllers that are connected to a drive system and a steering system of the electric pallet jack. The logic controllers can be in communication with one or more sensors that enable determinations of pallet jack velocity, pallet jack acceleration, and a rate of turning for the electric pallet jack. The logic controllers can be configured to provide maximum velocity, maximum acceleration, maximum deceleration, and maximum rate of turning limitations to maintain control over an object transported by the electric pallet jack. The logic controllers can determine whether the maximum thresholds of the electric pallet jack are exceeded by an operating variable and can modulate the amount of power provided by the drive system to reduce the operating variable below the associated threshold.
