Polyurethane Buffers

Polyurethane buffers are polyurethane buffer elastomer product. After more than 20 years of use, it has been proven that this product is an ideal buffer device. It is installed on various mechanical equipment with frequent collisions, thereby ensuring the normal operation of the equipment and reducing equipment and personnel accidents caused by collisions. Safe production is guaranteed.

The polyurethane buffer uses the special microporous bubble structure of the polyurethane material to absorb energy and buffer. During the impact, it is equivalent to a spring with multiple air bags for damping.

It is light in weight, cheap in price, easy to repair and replace, has good impact and pressure resistance, good corrosion resistance, no noise and no sparks during the buffering process, and is especially suitable for explosion-proof occasions.

A. Conduct regular inspections (at least once per quarter);

B. Use should be avoided under environmental conditions such as low temperature (below 40°C) or high temperature (above 80°C) and humidity (above 85°C);

C. It should not be used under strong acid or alkali environmental conditions;

D. When installing and replacing the buffer, refer to the instruction manual and icons;

E. The end face of the buffer installed on the crane should be vertical if the collision object is consistent with the center of the buffer in the direction of movement and should not be placed at an angle;

F. When the buffer is configured such that when the buffer collides with the buffer, buffers with the same diameter should be used, and the longitudinal length of the buffer should be kept as consistent as possible;

G. When installing the buffer, there should be a certain amount of space around it to avoid collisions, extrusion and other accidents with other components;

H. The buffer should be stored at normal temperature and placed in a ventilated and dry place;

l. If the polyurethane is found to be cracked or falling off, it should be replaced in time.

1. Only by using the buffer correctly can the service life of the buffer be ensured and extended. Make sure the buffer is correctly selected.

2. It is prohibited to paint or weld on the buffer.

3. It is prohibited to paint or mark the piston rod. (To prevent oil leakage and reduce the life of the buffer)

4. The buffer is filled with hydraulic oil, which is flammable. Never use near open flames and do not throw into fire. Check the strength of the installation position before use. If the buffer is installed in a place that lacks strength, it will be easily damaged.

5. The following table shows the installation torque of the lock nut. Due to vibration, too loose or too tight locking nut will cause the buffer to be unstable during use.

6. It is forbidden to put the buffer together with corrosive materials such as acids, solvents, emulsified cutting oils, etc., and package them well to avoid contact with dust, steam, etc.

7. Make sure to use the buffer within the applicable temperature (-10C 80C. If used under special temperatures, please contact us.

8. When installing the buffer, the impact object should be perpendicular to the axis of the buffer. If the degree deviation is greater than 1, the piston rod will bend to varying degrees due to the large lateral load, which will cause the piston rod to recover and accelerate the failure of the seal, resulting in oil leakage and shortening the life of the buffer.

Why Use Polyurethane Buffer for Bridge Crane?

Energy Absorption

Polyurethane buffers are designed to absorb the energy of impact and cushion the collision, which helps to reduce the damage caused to the crane and surrounding structures.

Durability

Polyurethane is a very durable material that can withstand frequent use and heavy loads, making it an ideal choice for bridge cranes that are constantly in operation.

Versatility

Polyurethane buffers can be customized to fit a variety of bridge crane configurations and requirements, making them a flexible and versatile option.

Noise Reduction

Polyurethane buffers can help to reduce noise levels during crane operations, which can be particularly important in busy industrial environments where noise pollution is a concern.

Safety

By reducing the impact of collisions and minimizing the risk of damage to the crane and surrounding structures, polyurethane buffers can help to improve the safety of bridge crane operations and reduce the likelihood of accidents or injuries.

Applications of Polyurethane Buffers

Polyurethane Buffers are safety protection devices that can be applied to a wide range of material handling applications such as:

• Industrial
• Construction Cranes
• Elevators
• All corners around automobiles
• All kinds of transmission devices

This buffer also can absorb the impact energy and transform it into elastic potential energy because of its micro-cellular structures. This is provided through the damping effect in the micro-cellular 'gas' spring.
