Product Introduction
The Raico Wireless Anti-Overwind Limit Switch is a safety protection device specially designed for hoisting equipment such as truck cranes and mobile cranes. Adopting wireless transmission technology, it eliminates the need for complex wiring. When the hook rises to the preset limit height, it automatically cuts off power and triggers an alarm, effectively preventing hazards like steel wire rope overwinding and hook crashing. It is a core component to ensure the safety of hoisting operations.

Installation & Maintenance Tips
Before Installation: Be sure to remove the safety pin on the pull rod (see blue label prompt) to ensure the switch can be triggered normally.
Installation Position: It is recommended to install the transmitter on the crane jib head and fix the receiver in the cab or beside the equipment control box to ensure unobstructed signal transmission.
Regular Inspection: Check the wear condition of the steel wire rope monthly, replace the transmitter battery every 6 months, and perform a function test every 12 months.
Troubleshooting: If signal abnormality occurs, try replacing the battery or adjusting the relative position of the transmitter and receiver to avoid obstruction by metal obstacles.
