Where should shackles be installed on an elevator system?

Shackles should be installed on the car crosshead and counterweight frame because this is where they play a crucial role in connecting the hoisting mechanism to the elevator car and counterweight. The car crosshead provides a stable point for the shackles, ensuring that the load is distributed evenly and securely during operation. This location allows for proper alignment and smooth movement of the elevator system, minimizing the risk of wear and tear on components.

Positioning shackles at the car crosshead and counterweight frame ensures that they adequately support the dynamic loads encountered during travel, such as the weight of the car and passengers, as well as the counterbalance forces. This strategic placement is critical for maintaining safety and operational efficiency within the elevator system.
