Yellow Painted Crane Buffer

The part of Crane - Buffer

The aim of adding a Overhead Crane buffer to the contact area between the end stop and trolley or crane is to absorb the majority of energy produced in an impact shock. Following is a list of two buffer forms most commonly in use today.

Polyurethane Buffer

Advantages of Crane Parts:

• Lightweight design available at a competitive price;
• Ease of maintenance and repair;
• Resistant to corrosion, impact and stress;
• Generate neither noise nor sparks during operation, thus suitable for use in explosive atmosphere.

Technical Features:

• Crane buffer density:0.55~0.65
•  Shore hardness:50-65
• Compressive Strength(50% compression):12~15kg/cm²
  
• Operating Temperature:-30℃~60℃

Hydraulic Buffer

Advantages:

• With the increase in the extent of compression, the number of holes that allow fluid to pass through will be reduced to ensure a uniform speed at which the buffering process is carried out;
• Despite its compact design, this series of crane buffer is able to absorb a large amount of energy;
• This hydraulic buffer enables a maximum deceleration of the running crane or trolley while coming in a minimum size. For cranes with high mass or speed exceeding 2m/s, the buffer just provides a most suitable solution.

Gantry Crane Technical Features:

• Absorb 80% to 100% of energy produced in impact shock;
• Angle of deflection after collision is controlled within the range between 0 and 1;
• Operating temperature:-25℃~80℃;
• Suitable for use on heavy-duty cranes or in special applications.
