What is a “dummy” in elevator terminology?

In elevator terminology, a "dummy" refers to a non-operational car that serves as a counterweight. This component is crucial for the balanced operation of the elevator system. By having a dummy car positioned opposite to the working car in the hoistway, the overall weight distribution is stabilized. This helps reduce the amount of energy needed to lift the operational car and enhances the efficiency of the system.

The dummy car contributes to the proper functioning of the elevator by ensuring that there is a consistent counterbalance, which minimizes wear and tear on the motor and other mechanical elements while ensuring a smoother ride for passengers. Understanding this concept is essential for anyone studying elevator systems, as it highlights the importance of balance and counterweight in elevator design and operation.
