摘要

The trolley for running on gutter shaped track has a chassis (2) supporting a seat (3) and a pair of foot locks. There are two non-steering side wheels (7) and a central steering wheel (16). The central pivot (13) of the latter is staggered relative to the wheel shaft (11). Movement of the pivot moves the vehicle in the same direction. There is also a brake, operated by the driver. The non-steering wheels are at the back and the pivot of the front wheel is in front of its shaft. The track may be laid up the side of a mountain.
