A palletizer-depalletizer cell includes a bi-directional pallet transport system with more than one independently driven pallet transports, each with a different pallet holder independently movable relative to a cell frame. Placement of case units commissioning a pallet layer loading a pallet, and removal of case units decommissioning a pallet layer unloading another pallet are both effected at the common pallet layer interface at a predetermined level of the cell frame. The pallet transports independently index a first and a second of the different pallet holders, each independently holding the pallet loading at the common pallet layer interface.

A system and a method for remotely controlling a vehicle for safe loading and unloading of cargo, may include a vehicle, and a remote control device that performs data communication with the vehicle control device of the vehicle, and the vehicle sends a request to the remote control device for remote control when arriving at a destination, moves to a work location and performs work under control of the remote control device, requests the remote control device to deactivate the remote control when the work is completed, and performs exit of the destination through autonomous driving of the vehicle.

Disclosed is a payload lifting device capable of stably lifting a payload using one lift-driving unit. In the payload lifting device including a lift-driving portion configured to vertically lift a payload, the lift-driving portion includes lift-driving units configured to generate a driving force for vertically lifting the payload, a first power transmission portion including first power transmission members which vary in vertical positions and apply a vertically lifting force to one side of a bottom of the payload when a first rotational shaft rotated by the driving force of the lift-driving units rotates, and a second power transmission portion including second power transmission members which vary in vertical positions and apply a vertical lifting force to the other side of the bottom of the payload when a second rotational shaft rotated by the driving force of the lift-driving units rotates.

A computer-implemented process receives into memory, information designating a task to be performed on an industrial vehicle. The task has a metric associated therewith. The process also extracts vehicle operational data that is generated on the industrial vehicle in response to the industrial vehicle executing the task. The process further receives into memory, information identifying a set of target scores, each target score of the set of target scores defining a different measure of performance associated with the task. The process yet further computes a task evaluation score for each target score in the set of target scores based upon the corresponding measure of performance associated with the task, and creates an adjusted task evaluation indicative of industrial vehicle performance that takes into account an aggregation of the task evaluation score computed for each target score in the set of target scores.
