ABSTRACT:
A system for loading, off-loading and/or transferring conventional international shipping containers with respect to transport vehicles which system includes a plurality of powered jacks each of which includes upper and lower container attachment members which are selectively engageable with upper and lower corner lock castings of the containers. Each attachment member is carried by a guide sleeve slideably mounted relative to a vertical standard with an upper guide sleeve being drivingly engaged with a power driven member such that, with the attachment members engaged with the corner locks of the container, the simultaneous activation of four jacks allows the elevation and/or lowering of a shipping container relative to a vehicle.
