摘要
An elevator system comprising multiple elevator cabs operating independently in an elevator shaft. Each cab comprises a pair of underslung suspension cables, equally spaced apart from the center of the cab; a lift motor at a top surface of the shaft having an axle with a traction sheave at each end of the axle; each set of suspension cables connected at a first end to a hook at the top surface, engaging a pulley connected to a counterweight, engaging a first traction sheave, engaging a cab pulley, slung under the cab, engaging a second cab pulley and terminating at a second end connected to the top surface. Each set of four cab pulleys of each elevator cab is progressively and symmetrically located closer to the center of each cab, so that suspension cables, counterweights, pulleys, hooks, lift motors, axles, and traction sheaves will not horizontally or vertically conflict with each other.
