Overhead Crane Practice Test 2025 – Complete Prep Guide

Limit switches are critical components in crane operation that function as safety devices, ensuring that the crane does not exceed its designed movement limits. These switches are strategically positioned to detect the position of the crane's moving parts, such as the hoist, trolley, or boom. When activated, limit switches stop the movement of the crane or its components when they reach a predetermined point, thereby preventing potential hazards or mechanical failures that could result from over-travel.

By preventing the crane from going beyond its specified range of motion, limit switches help maintain operational safety, protect the equipment from damage, and ensure that the crane operates within its intended parameters. This is particularly important in preventing accidents that could harm personnel or damage surrounding structures and equipment. Overall, the inclusion of limit switches in crane design is a key part of a comprehensive safety strategy in overhead crane operations.
