A buffer stopper consists of a damping material and a supporting structure. The damping material generates the damping force, while the supporting structure transmits it to the moving object. Common types include hydraulic buffers, pneumatic buffers, and spring buffers. They function by generating damping forces and converting energy to slow down or eliminate impact forces.

Hydraulic Buffer

Hydraulic Buffer: Absorbs and mitigates impact forces and vibrations through hydraulic damping, preventing damage from hard collisions.   

Improved Stability: Converts impact forces into oil flow, enabling smooth stops and enhancing equipment stability and service life. 

Equipment Protection: Reduces vibration and impact effects, lowering failure rates, maintenance costs, and extending operational lifespan.    

No Rebound Effect: Generates no rebound forces after buffering, eliminating secondary impact risks.

Polyurethane Buffer

The polyurethane (PU) buffer utilizes its microporous bubble structure to absorb and dissipate impact energy, functioning like a spring with multiple airbag dampers to reduce vibration and shock.

Lightweight and easy to install

Maintenance-free, reducing operational costs

Excellent cushioning and impact resistance

Safe and reliable operation

Buffer Stop (Heavy-Duty Crane Rail Bumping Post)

The buffer stop is a heavy-duty safety device installed at the terminal ends of crane tracks to prevent overtravel and derailment. Constructed from high-strength steel, it serves as a robust physical barrier that absorbs kinetic energy and ensures safe operation.

Absorbs collision kinetic energy, minimizing damage to crane and rail systems.

Configurable to standard rail profiles (e.g., DIN536-1 A65, A75, A100, A150, or custom).

Pre-drilled base plates for easy installation with high-tensile bolts.

Weather-resistant materials for low maintenance.
