A drive arrangement for an elevator car and a machine roomless elevator incorporates a machine having a drive sheave, a pair of right and left car side sheaves disposed beneath the car, a counterweight with a pair of top mounted sheaves, and a hoist cable including a plurality of ropes. The car is shifted to one side of the hoistway and the car guide rails are shifted forward in the hoistway in order to create a large pocket in a rear corner of the hoistway for the counterweight. In this manner, the elevator car can nest beside the machine in the top of the hoistway limiting the required top hoistway space and creating a minimal hoistway footprint. |
