Compensation Chains for traction elevators

As the elevator travels, the length of the hoisting cables (which support the car and the counterweight) changes. The compensation chain helps to offset the weight of these cables, ensuring that the load on the motor remains relatively constant.

By balancing the weight, the motor doesn't have to work as hard, which can lead to energy savings and reduced wear and tear on the system.

The chain itself is typically made of heavy-duty steel links. It is designed to be durable and able to withstand the constant tension and movement.

The chain is attached to both the bottom of the elevator car and the counterweight. This ensures that as the car moves, the chain adjusts accordingly to maintain balance.

When the elevator car moves up, the hoisting cables supporting the car become shorter, and the cables supporting the counterweight become longer. The compensation chain, being attached to both, helps to balance this weight shift.
