Travel bridge between fixed ramp and lorry - comprises hinging plates mounted on vertical ram in front of ramp to swing out into common plane for use

摘要

The travel bridge rests at opposite ends on a fixed ramp and the platform of a lorry etc to be loaded. In front of the ramp(4) is a vertical jack, typically a ram(1), to whose top end two bridge plates (2, 3), parallel to each other, are attached. These swing out into a common plane for use, one resting on the ramp and the other on the platform. Lips (8, 9) can be mounted on the plate free edges, hinging out into the same plane, and folding under them when not in use.
