Engineered for demanding industrial environments, the Hydraulic Elevator Damper delivers exceptional vibration control and safety for heavy-duty vertical transportation systems. With its high load-bearing architecture and corrosion-resistant construction, this critical component extends equipment lifespan while ensuring smooth elevator operation. Manufactured by Hengshui Haogu, a certified supplier since 2025, our dampers meet rigorous international standards for industrial lifting applications worldwide.
The patented hydraulic absorption mechanism effectively dissipates kinetic energy during elevator deceleration, preventing structural stress and mechanical wear. Precision-engineered tolerances guarantee consistent performance across temperature variations from -20°C to 80°C. Below are key technical specifications for standard models:
| Parameter | Specification |
|---|---|
| Operating Principle | Double-acting hydraulic compression |
| Standard Stroke Length | 150-300mm (customizable) |
| Maximum Impact Force | Up to 150 kN |
| Rebound Control | Adjustable damping coefficient |
Key performance advantages include:
- • Corrosion Protection - Specialized surface treatment withstands humidity, chemicals, and salt spray environments
- • Maintenance Efficiency - Sealed cartridge design eliminates lubrication requirements
- • Installation Flexibility - Multiple mounting configurations available for retrofit applications
Our manufacturing facility utilizes automated CNC machining centers to maintain dimensional accuracy within ±0.05mm. Each unit undergoes pressure testing at 1.5x rated capacity before shipment. Compatible with freight elevator systems from major OEMs including Otis, KONE, and Schindler.
