Overhead Crane Practice Test

Question: 1 / 400

What is the role of the trolley in an overhead crane system?

It allows the hoist to move vertically.

It controls the weight of the load.

It allows the hoist to move horizontally along the bridge.

The correct answer emphasizes the trolley's function in enabling the hoist to move horizontally along the bridge of the overhead crane system. This horizontal movement is crucial for positioning loads accurately over designated areas, which is essential for effective material handling. The trolley is typically mounted on the bridge and equipped with wheels, allowing it to traverse the length of the crane's structure.

This movement capability is vital because it allows operators to transfer loads across different points in a work area without needing to relocate the entire crane. The integration of the trolley enhances the crane's versatility and efficiency, facilitating smooth and precise operations while minimizing risk and enhancing safety within the workspace.
