Product Introduction

Products Description

Polyurethane crane buffer is a type of safety protective collision device with wide adaptability. It can be used in equipment such as cranes, hoists, tower cranes, loaders, elevators, and mine cars. When the equipment reaches its limit position or encounters a collision, this safety collision device can quickly convert the impact energy into elastic potential energy. Crane buffer features good hardness, high strength, fast recovery, oil resistance, and resistance to weak acid and weak alkali, among others.

Products Advantages

crane buffer

1. Superb collision resistance: The crane buffer is made of polyurethane material, which can absorb a large amount of impact energy. It has high hardness, minimal rebound, excellent compressive recovery, greatly extending the service life of the crane buffer.
2. Excellent shock resistance: It has a good buffering effect and strong compressive performance.
3. Noiseless: During the buffering process, there are no sparks, and it has strong explosion-proof characteristics, ensuring safety and reliability.
4. Chemical stability: Excellent insulation, explosion-proof, corrosion resistance, heat resistance, cold resistance, oil resistance, and aging resistance.
5. Simple structure, easy installation and maintenance.

Products Application

There are several types of crane buffers. Here are some common types:

1. Hydraulic Buffer: It uses a hydraulic system to absorb and dissipate the impact force of the crane. It has a higher load-carrying capacity and good buffering effect.

2. Spring Buffer: It utilizes the elasticity of springs to cushion the impact of the crane. It is suitable for small cranes and low impact energy applications.

3. Air Buffer: It absorbs and reduces the impact of the crane using air pressure in cylinders. It offers good buffering effect and high durability.

4. Hydro-Pneumatic Buffer: It combines the characteristics of hydraulic and pneumatic buffers. It provides both the load-carrying capacity of a hydraulic system and the shock absorption effect of a cylinder.

5. Magnetic Buffer: It uses magnetic force to reduce the impact of the crane. It is suitable for special environments or applications requiring precise control.

These are some common types of crane buffers. There may also be other specialized or customized buffer types available based on specific requirements.
