What component transfers the lifting force in a traction elevator?

In a traction elevator, the component that transfers the lifting force is the hoisting cable. This cable is connected to the elevator car and wraps around a pulley. When the motor drive operates, it rotates the pulley, causing the hoisting cable to either raise or lower the elevator car.

The hoisting cable is critically important because it directly interacts with the elevator car's movements. It is engineered to withstand significant tensile forces, enabling it to lift heavy loads safely and efficiently. The cable ensures that as the motor turns the pulley, the car is either lifted to a higher floor or lowered to a lower one, depending on the desired direction of movement.

The other components mentioned, such as the counterweight, motor drive, and pulley system, all play supportive roles in the operation of the elevator. The counterweight helps to balance the load, reducing the amount of energy required from the motor. The motor drive provides the necessary power to move the elevator, while the pulley system serves as a mechanism to guide and change the direction of the hoisting cable's movement. However, it is the hoisting cable that is responsible for transferring the lifting force.
