Abstract:
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.

Claim (Index 1):
An elevator system comprising a plurality of elevator cabs operating independently of each other in an elevator shaft of a structure, the elevator system comprising:\n at least two elevator cabs positioned vertically in the elevator shaft, each cab comprising:\n a first set of suspension cables and a second set of suspension cables, equally spaced apart from a center of each cab and substantially parallel to a front wall and a rear wall of each cab, \n wherein for at least one elevator cab of the at least two cabs, each set of cables connected to each cab by two sets of cab pulleys located at a bottom of the cab such that each set of cables is slung under the bottom of the cab, wherein the two sets of cab pulleys for each set of suspension cables are symmetrically positioned at the bottom of the cab; \n wherein for at least one other elevator cab of the at least two cabs, each set of cables connected to each cab by two sets of cab pulleys located at a top of the at least one other cab such that the at least one other elevator cab is suspended from suspension cables that engage cab pulleys above the at least one other elevator cab; \n a lift motor at a top surface of the shaft comprising an axle and a first traction sheave at a first end of the axle and a second traction sheave at a second end of the axle, wherein the first traction sheave engages the first set of suspension cables and the second traction sheave engages the second set of suspension cables; \n a counterweight for each set of suspension cables connected to a counterweight pulley, the first set of suspension cables connected at a first end to the top surface of the shaft, engaging a first counterweight pulley connected to a first counterweight, engaging the first traction sheave, engaging two opposing cab pulleys at the bottom of the at least one elevator cab or at the top of the at least one other elevator cab, and connected at a second end to the top surface of the shaft; the second set of suspension cables connected at a first end to the top surface of the shaft, engaging a second counterweight pulley connected to a second counterweight, engaging the second traction sheave, engaging another two opposing cab pulleys at the bottom of the at least one elevator cab or at the top of the at least one other elevator cab, and connected at a second end to the top surface of the shaft; \n wherein each lift motor of each cab moves its corresponding two sets of suspension cables in unison with equal force and each cab is moveable rectilinearly within the elevator shaft independently of each cab; and wherein the two opposing cab pulleys for each set of suspension cables of each cab, from each cab to a next cab of the at least two cabs, are progressively and symmetrically located closer to the center of each cab with respect to the front wall and the rear wall, such that for each cab, suspension cables, counterweights, pulleys, lift motors, axles, and traction sheaves will not horizontally or vertically conflict with each other.
