Abstract
A conveyance system having an overhead guide rail above a surface and one or more vehicles which are guided by the rail and partially supported on the surface by a wheel structure. Preferably, the guide rail includes the stator of a linear induction motor which cooperates with a rotor element in a propulsion member for the vehicle. A handpole on the vehicle connects the propulsion member to a passenger-carrying platform on the wheel structure. The handpole is sufficiently vertical to be readily grasped by a passenger for support while riding and assistance in getting on and off the vehicle, and yet the pole is sufficiently inclined to partially support the vehicle and permit its movement in response to the propulsion member. The preferred system uses simple, lightweight vehicles which can be readily installed over a pre-existing surface such as a sidewalk or corridor and are arranged to move continuously therealong at a slow passenger-transfer speed and a faster speed between transfer points.
