Question: 1 / 400

What does the hoist limit switch prevent against?

Overloading

Excessive height

The hoist limit switch is designed to prevent excessive height by stopping the hoisting operation when the load reaches a predetermined upper limit. This functionality is crucial for ensuring safety during crane operations, as it helps to avoid situations where the load could rise too high, potentially causing collisions with overhead structures or endangering personnel working nearby. By effectively controlling the maximum height that the load can reach, the limit switch contributes to the safe and efficient operation of the overhead crane system.

While aspects like overloading, damage to the hook, and chain slippage are important considerations in crane safety, the specific role of the hoist limit switch is to monitor and manage the vertical movement of the load, making sure it does not exceed safe operating conditions.
