Lift Hydraulic Oil Buffer OH-10, OH-16, OH-20

Lift Hydraulic Oil Buffer OH-10 OH-16 OH-20

OH-10, OH-16, and OH-20 Elevator Hydraulic Oil Buffer series provides compact yet powerful safety solutions for vertical transportation. These energy-consuming elevator components are specifically engineered to manage terminal over-travel for an elevator car or counterweight, ensuring the smooth and safe transport of people in residential buildings and smaller commercial buildings.

By utilizing HL46 hydraulic oil, these buffers convert kinetic impact into thermal energy, meeting the strict elevator safety standards of EN 81-20/50 and GB 7588.

Technical Specification Summary

The OH-10 through OH-20 series is tailored for varying lift speeds, offering a reliable safety solution for low-to-medium rise high-rise buildings.

Core Performance Features

• Advanced Energy Consumption: Designed as an energy consumption type, these buffers utilize a precision-engineered internal piston that forces HL46 hydraulic oil through graduated orifices. This eliminates the “rebound” effect, providing a constant and controlled deceleration.

• High Weight Capacity: Despite their streamlined design, these buffers handle a substantial weight capacity of up to 4,545 kg, making them versatile enough for both standard passenger and heavy service lift systems.

• Integrated Safety Monitoring: Every unit features a factory-fitted electrical safety limit switch. If the buffer is engaged, the switch interrupts the elevator safety circuit to prevent further movement until a manual inspection is performed.

• Durable Engineering: The plunger is treated with hard chrome plating to resist the damp conditions often found in the pit of residential buildings, ensuring the seals remain leak-free and functional for years.
