Preparation before installation
Inspect components: Check the traction sheave and its accessories, including the wheel groove, wheel hub, key, bolt, etc., to ensure that there are no defects such as damage, deformation, cracks, etc. The surface should be smooth without obvious wear and scratches.
Prepare tools: Prepare the tools required for installation, such as wrenches, screwdrivers, vernier calipers, dial indicators, lifting equipment, etc.
Determine the installation position: Determine the installation position of the traction sheave according to the design requirements of the elevator and the hoistway layout. Usually, the traction sheave should be installed on the load-bearing beam in the machine room, and its position should be accurate, corresponding to the car and counterweight device in the hoistway.

Function:
Transmitting power: connected to the drive motor, the torque generated by the motor when running is transmitted to the traction rope through the traction wheel, and then driving the car and counterweight device to move up and down, realizing the elevator's function of carrying people or goods.
Generate traction: rely on the friction between the traction wheel and the traction rope to generate traction. This force is the key to enable the elevator car and counterweight to run smoothly in the predetermined direction. Its size is related to factors such as the shape and material of the rope groove of the traction wheel and the tension of the traction rope.
Change the direction of movement: through reasonable arrangement, the traction wheel can change the direction of movement of the traction rope, so that the car and counterweight can move up and down in the vertical direction in the hoistway to meet the traffic needs between different floors in the building.
Balance the car and counterweight: during the operation of the elevator, the traction wheel cooperates with the counterweight device to adjust the winding method and tension of the traction rope on the traction wheel to balance the weight of the car and counterweight, reduce the load of the motor, reduce energy consumption, and improve the stability and safety of the elevator operation.
Speed ​​limit and brake: In the elevator safety system, the traction sheave works together with the speed limiter, safety clamp and other components. When the elevator is in an abnormal situation such as overspeed, the speed limiter will be triggered, and the safety clamp will be activated through the traction sheave to stop the car or counterweight on the guide rail to prevent serious accidents such as falling or hitting the top of the elevator, and ensure the safety of passengers and equipment.
