What is the purpose of overhoist and over lower switches?

Overhoist and overlower switches are safety devices used in cranes and hoisting equipment to prevent the load from being lifted too high or lowered too far. The overhoist switch stops the hoisting mechanism when the load reaches a predetermined upper limit, while the overlower switch does the same for the lower limit. These switches help protect both the equipment and the load, ensuring safe operation by preventing accidents and potential damage. They are critical components in maintaining the safety and reliability of lifting operations.
