Overview
A Rotary Gear Limit Switch is a crucial safety and control device used in cranes, hoists, and material handling equipment. It is designed to monitor and control the movement limits of crane mechanisms, preventing over-travel and ensuring safe operation. By providing precise position feedback, it safeguards equipment and operators from mechanical overload, collisions, or accidents.

Key Features
- Precise Position Control: Accurately monitors crane travel limits.
- Safety Enhancement: Prevents over-travel and mechanical damage.
- Durable Construction: Built to withstand heavy-duty industrial conditions.
- Easy Integration: Can be used with various electrical and control systems.
- Reliable Performance: Maintains functionality in dust, vibration, and temperature variations.
How It Works
The Rotary Gear Limit Switch operates using a mechanical rotary gear system connected to the crane’s moving parts:
-
As the crane hook, trolley, or bridge moves, the rotary gear rotates proportionally.
-
When the movement reaches the preset limit, the switch activates an electrical contact that stops the crane motor or triggers an alarm.
-
This ensures that the crane does not exceed safe operational limits, protecting both the load and the crane structure.
Some models also feature adjustable cams and multiple contacts for fine-tuned control and automation integration
