limit stop

A limiter is a mechanical or electrical device primarily used to limit or control the position of moving parts in a machine, equipment, or system to prevent them from exceeding a predetermined safety range. It usually consists of one or more blocks and corresponding slots, which achieve limit control of moving parts through physical contact or signal detection.

1、 Definition

A limiter is a mechanical or electrical device primarily used to limit or control the position of moving parts in a machine, equipment, or system to prevent them from exceeding a predetermined safety range. It usually consists of one or more blocks and corresponding slots, which achieve limit control of moving parts through physical contact or signal detection.

2、 Working principle

The working principle of the limiter is mainly based on the principle of mechanical contact or non-contact signal detection. When the mechanical motion reaches or exceeds the set position, a signal will be sent or certain control measures will be taken to stop or change the direction of motion. The specific working principle depends on the type of product and the application scenario.

3、 Application Fields

Widely used in various industries, especially in scenarios where the position of moving parts needs to be controlled. Here are some of the main application areas:

1. Automotive industry: used to control the opening and closing angles of doors, engine covers, trunk, etc., to prevent damage or safety hazards caused by excessive opening. At the same time, it is also used to control the large steering angle of the steering wheel, preventing the driver from turning excessively and causing the vehicle to lose control.

2. Lifting machinery: It is an important safety device in large lifting equipment such as tower cranes and bridge cranes. They can limit the lifting height, rotation angle, and weight and amplitude of the lifting arm, ensuring the safe operation of lifting operations.

3. Industrial automation: Used in industrial robots, automated production lines, and other equipment to restrict the movement range of moving parts such as robotic arms and conveyor belts, preventing them from exceeding the work area or colliding with other equipment.

4. Elevator industry: The up and down operation of elevators cannot be separated from control. They can limit the operating range of the elevator car and prevent accidents such as roof jumping or squatting.

4. Summary

As an important safety device, limiters play an irreplaceable role in various fields. They effectively prevent accidents and protect the safety of equipment and personnel by restricting or controlling the position of moving parts. With the continuous development of technology, the variety and functions of products are also constantly enriched, providing more reliable and efficient security guarantees for various industries.
