The car is supported in the hoistway so as to be movable up and down via first guide rails a and b fixed to the hoistway. The counterweight is supported in the hoistway so as to be movable up and down via second guide rails a and b fixed to the hoistway.

A support beam is provided at an upper end of the hoistway. Further, a hoisting machine having a traction sheave is fixed to the support beam.

The car and the counterweight are suspended in the hoistway via three main ropes a, b, and c, for example. As shown in the drawing, one end portion a of the main ropes a, b, and c is connected to a first rope hitch fixed to the upper end of the first guide rail b. The other end b of the main ropes a, b, and c is connected to a second rope hitch fixed to the support beam.

Intermediate portions c of the main ropes a, b, c are continuously wound around a pair of car upper sheaves a, b provided in the car, a traction sheave of the hoisting machine, and a pair of counter weight sheaves a, b provided in the counter weight. The intermediate portion c of each main rope a, b, c is guided in the running direction in the hoistway via the first guide sheave and the pair of second guide sheaves a, b.

In the vicinity of the traction sheave, the running direction of the main ropes a, b, c is guided by the rope grooves provided in the traction sheave. Therefore, the swing of the running main ropes a, b, c is small to a negligible extent, and the pitch P between the adjacent main ropes a, b, c is kept fixed.

According to the present embodiment, the protective cover is attached to the hoisting machine. The protection cover is an element for preventing foreign matters from being caught between the main ropes a, b, and c and the rope grooves provided on the outer circumferential surface of the traction sheave, and faces the main ropes a, b, and c wound around the traction sheave.

The protective cover has a seam a extending in the direction in which the main cords a, b, c are arranged. The slit a extends straight above the traction sheave in the direction in which the main ropes a, b, and c are juxtaposed.

Main ropes a, b, and c suspending the car and the counterweight in the hoistway are examples of elevator wire ropes. The main ropes a, b, and c have a common structure, and therefore, a single main rope a will be described as a representative.

The elevator is a Chinese utility model patent (application number: CN201821983857. X). Wherein the belt sheave that can be used in the present application can be mounted on the elevator of the above patent.

Of course, the embodiment can also be used for being installed on elevators with other structures. The description is omitted, and the pulley according to the embodiment of the present application will be described below.
