A gangway comprising a fixed platform. A support structure is connected to the fixed platform in a manner that allows the support structure to rotate with respect to the fixed platform. A releasable position locking assembly that inhibits rotation of the support structure in a raising direction is also provided. The releasable locking assembly includes a closed-loop fluid arrangement.

In some embodiments, apparatuses and methods are provided herein useful to loading totes. In some embodiments, there is provided a system for loading totes on shelves of racks secured inside a delivery truck including: a plurality of hydraulic lifts. Each of the plurality of hydraulic lifts comprises: a hydraulic system; a top surface; a stop mechanism; and at least one lift-to-rack alignment sensor; and a control circuit configured to: access a multi-dimensional positional matrix; determine a physical location associated with a tote based at least on the multi-dimensional positional matrix and a tote identifier; determine a particular hydraulic lift of the plurality of hydraulic lifts based on the physical location; activate the stop mechanism to position the tote on the top surface of the particular hydraulic lift; and operate the hydraulic system to move the tote to a height of a shelf of a rack based on the physical location.

The present invention relates to a hydraulic height adjusting device for installing a heavy-weight structure to secure stable horizontal bearing power against a horizontal load of a heavy-weight upper structure. The present invention includes a lower frame which is installed on a top surface of the carrier and is provided with a plurality of receiving portions formed in an upwardly opened shape; and a hydraulic cylinder which is disposed in and engaged to the respective receiving portions of the lower frame, the hydraulic cylinder being moved in a vertical direction to adjust the height of the upper structure, in a state in which an upper end thereof supports the upper structure. The receiving portion is provided with a support guide which is interposed between an inner wall of the receiving portion and the hydraulic cylinder to annually enclose the hydraulic cylinder and thus prevent the hydraulic cylinder from being tilted.

A portable lift assembly that is temporarily mountable to the ends of standardized shipping containers, that allows cargo to be loaded and unloaded without a raised loading dock. The assembly includes a frame having pin members that engage standard corner castings on the access end of a shipping container so that the weight of the lift assembly and cargo are borne by the end of the container. Cargo is raised and lowered on a platform, with power being supplied from onboard the portable assembly. The portable assembly may be transported between containers and installed using a forklift or similar machine.
