Crane Travelling Limit Switches from China Manufacturer

Crane Travelling Limit Switches

The travel limit switch is an electrical appliance for the crane to control the motor according to the operation. According to different purposes, crane accessories-travel limiter can be divided into two types: terminal switch (limit switch) and switch (protection switch). The end switch is used to limit the operation of the mechanism within a certain range and is installed at the end of the stroke of the operating mechanism. The switch is used to protect the operator. For example, the switch from the cab to the hatch of the upper main beam platform is called a hatch switch, also known as a door interlock. Crane travelling limit switches have almost limitless applications in regulating the operation of a crane to prevent potential accidents. For example, when a rope comes out of a groove or when two trolleys are prevented from hitting the same bridge structure.

Crane Travelling Limit Switches introduction

The crane travelling limit switch is an important safety device used to prevent electric trams or bridges from hitting at high speeds. Limit switches also prevent overhead cranes from lifting loads heavier than their rated capacity. There are various types of limit switches that help prevent the hoist from overtraveling and some that help protect the hoist motor from overheating. There are usually several limit switches in a crane operation. While one switch can indicate that the crane is close to reaching the safe travel limit, another switch can indicate when the safe travel limit has been reached and stop the crane from moving further. Heavy-duty limit switches are an essential part of providing a safe environment in overhead crane applications.

Limit switches are operated by contact with the crane hook block. When activated, the limit switch interrupts power to the elevator motor. This prevents the hook block from colliding with the cable drum, which could cause a load drop or other unsafe condition. Limit switches can be remanufactured using existing specialty components.
The crane limit switches produced by our company are in strict accordance with European standards, modular production, easy to disassemble and install. If you need it, please contact us for a quotation as soon as possible!
