摘要： The load carrying platform shuttle has a static frame that defines a cam surface. A carriage is arranged to telescope into the static frame. A ramp has an outboard edge rotatably connected to the carriage. A cam follower is disposed on the ramp so as to engage with the cam surface. The cam surface and the cam follower cooperate such that an inboard edge of the ramp is automatically maintained at an elevated height whilst the carriage is disposed intermediate of an extended position and a retracted position and such that the inboard edge of the ramp is automatically maintained at a lowered height whilst the carriage is at the retracted position. The static frame is constructed from I-beams that are reinforced to increase their resistance to the bending moment applied by the carriage whilst it is in the extended position.

摘要： A load carrying platform shuttle (10) has a static frame (12) and a movable carriage (14). The frame is securable to a mounting location, such as a given working level of a multi-storey building under construction, and the carriage is arranged to telescope into the static frame between an extended position outboard of the mounting location and a retracted position inboard of the mounting location. The movable carriage can move between the extended position and the retracted position while carrying a load. The shuttle includes a motor (76) and gear assembly (72, 74, 78) for driving the movement of the carriage between the extended position and the retracted position while carrying the load.
