An autonomous dock station system having an automated material lift truck (AMT), a pallet conveyor, and a facility guidance system can automatically load and/or unload a trailer at a dock station. The autonomous dock station system can coordinate these components according to a workflow procedure. In some embodiments, the workflow procedure can begin with the pallet conveyor supplying a loaded pallet to a specified position. The AMT, initially guided by fixed guidance elements of the facility guidance system, can lift the pallet off the conveyor and transport it to a trailer entrance where the AMT switches from the facility guidance system to a trailer guidance system. The AMT can then carry the pallet to an unloading position, move the pallet to one side of the trailer as needed, unload the pallet and return to the pallet conveyor. The workflow procedure can repeat until the trailer is full.

The present disclosure provides an end-to-end cargo handling system. The end-to-end cargo handling system comprises a transportation unit comprising a first sensing agent, a lift unit comprising a second sensing agent, and a control module in communication with the transportation unit and the lift unit via a network, wherein the transportation unit and the lift unit are configured to move a cargo unit from a first location to a second location autonomously.

In one embodiment, an inventory storage module has a plurality of conveyor segments that define a movement path that has a closed shape, and at least one actuator that can move inventory storage containers along the movement path. Each actuator has a roller having a cylindrical body that has a first end, a second end that are offset from the first end along a central axis, and a cylindrical outer surface that extends from the first end to the second end. Each actuator has a helical track disposed around the cylindrical outer surface in a helical pattern. Further, each actuator has at least one track follower that can ride along the helical track when the roller is rotated about the central axis so as to move the inventory storage containers along an axial direction that is substantially parallel to the central axis.

The Pallet Loading Height Limiter is a very simple, and yet effective, non-powered, adjustable device for helping warehouse workers keep a shipping pallet load within safe and proper limits for height (and, consequentially, also weight). The device rolls on locking casters for easy use and storage. The device's frame has reinforcing brackets that minimize damage from passing forklifts, etc. The device's design makes it easy to repair if it is ever damaged. Because there is no globally-accepted standard for pallet sizes, this device may be made in various sizes (usually determined by country of origin of the pallet). That said, the North American pallet size (40 by 48) is the standard used for this application. This device works equally well with stringer- or block-type pallets. Using this device should help minimize material-handling injuries to workers that handle loaded pallets.

A modular and impactable frame which includes an integrated dock leveler. The frame includes opposing front plates, opposing side members, opposing base members and an integral bracing structure which connects each side member to a respective base member, the base members each have a base plate and a pair of front and back supporting legs, each base plate is secured to the grade and is adjustable in a side-to-side direction as well as adjustable in a front-to-back direction so as to securely conform to and attach to the contour of the grade.

In one embodiment, an inventory storage module has a first conveyor segment, a second conveyor segment spaced below the first conveyor segment, a first vertical lift disposed at a first end of the module, and a second vertical lift disposed at a second end of the module. The first and second lifts each transfer inventory carriers between the first and second conveyor segments. The first conveyor segment, the second conveyor segment, the first vertical lift, and the second vertical lift together define a conveying loop in a vertical plane, and the storage module translates inventory carriers around the conveying loop until a desired one of the inventory carriers is presented at one of the first and second module ends. An inventory item can be retrieved from, or stowed in, the desired one of the inventory carriers at the one of the first and second module ends.
