The arrangement of the single wheel of the first diversion sheave assembly can be used for two layouts of a ladder type with a machine room counterweight rear-mounted and a machine room counterweight side-mounted.

The second diverting pulley component is provided with two wheels and is arranged at two ends of the upper beam body, so that the second diverting pulley component can be used for a ladder type with a counterweight side arranged, and the two ladder type layouts with or without a machine room can be applicable.

When the second diversion sheave assembly is arranged on the upper beam body, namely the middle beam, the guide wheel does not need to be arranged when the elevator is arranged, the steel wire rope on the traction wheel directly winds the diversion sheave, the wrap angle of the traction wheel is increased, the traction force is increased, the energy consumption of the traction machine is reduced, the requirement on the wrap angle is avoided, the machine frame of the traction machine can be eliminated, and the material is saved. The second diversion sheave assembly is switched to the first diversion sheave assembly, so that the ladder type and the layout of the car frame can be easily changed without changing the design, and great cost saving and time saving are brought to the design and the manufacture.
