Abstract: An illustrative example elevator system includes a frame, a first elevator cab, a second elevator cab, and a plurality of sheaves associated with the first and second elevator cabs, respectively. A suspension assembly suspends the first and second elevator cabs within the frame. The suspension assembly has two ends in a fixed position relative to the frame. The suspension assembly includes a positive drive load bearing member along a first portion of a length of the suspension assembly and at least one other second load bearing member. A machine includes a drive sprocket that moves the positive drive load bearing member to cause movement of the first and second elevator cabs relative to the frame.

Abstract: An illustrative example elevator system includes a first vertical pathway, a second vertical pathway, and a transfer space situated to allow movement between the vertical pathways. An elevator car is selectively moveable along the respective vertical pathways and through the transfer space. At least one blocker has a passage condition and a blocking condition. The passage condition allows the elevator car to move from one of the vertical pathways into the transfer space when the transfer space is configured to receive the elevator car from the one of the vertical pathways. The blocking condition prevents the elevator car from moving from the one of the vertical pathways into the transfer space when the transfer space is not configured to receive the elevator car from the one of the vertical pathways.

Abstract: A support member configured for use in a machine room of an elevator system is provided including a base having a car end and a counterweight end. The counterweight end is arranged substantially parallel to a wall of the machine room, and the counterweight end is arranged at an angle relative to the car end. An idler sheave having a plurality of grooves is mounted to the base in an orientation generally parallel to the car end. The idler sheave is configured to rotate about a first axis of rotation. A plurality of individual sheaves is mounted to the based in a staggered configuration substantially complementary to the angle of the counterweight end relative to the car end. Each individual sheave is configured to rotate about a second axis of rotation parallel to the first axis of rotation.

IPC: B66B7/04
Abstract: A guidance mechanism for an elevator car is constructed and arranged to move along a lane defined at least in-part between two opposing first and second lane structures of a stationary structure. The guidance mechanism includes a first support structure supported by the first lane structure. The first support structure includes a first retainer face disposed between the elevator car and the first lane structure that substantially faces the first lane structure, and is spaced from the first lane structure. A first retention device of the mechanism is disposed, at least in part, between the first retainer face and the first lane structure. The first retention device is supported by the elevator car and is constructed and arranged to contact the first retainer face for limiting lateral movement of the elevator car away from the first lane structure and toward the second lane structure.
