Elevator Hydraulic Buffer

The H6 - H15 lift buffers are energy-absorbing buffers compliant with EN81-20 and EN81-50 5.5 standards, making them suitable for all lift construction applications. Their universal applicability allows for use in both passenger and freight elevators, whether installed beneath the car or beneath the counterweight. These buffers are approved for installation exclusively in vertically moving lifts with the piston rod oriented upwards.

Hydraulic buffers are critical components in elevator systems, designed to ensure safe and controlled movement between the elevator car and the shaft. These buffers function as a safety measure to absorb energy and minimize impact in case of sudden stops or emergency situations.

Operating on the principle of hydraulic resistance, these buffers consist of a piston within a cylinder filled with hydraulic fluid. During normal operation, as the elevator approaches the terminal floors or in the event of an emergency stop, the hydraulic buffer slows down the car's movement gradually and safely.

When the elevator nears the end of its travel, the hydraulic fluid in the buffer cylinder encounters resistance, which absorbs the kinetic energy of the moving elevator. This controlled resistance helps decelerate the car smoothly, preventing sudden jolts or impacts. In the case of an emergency, such as a brake failure or overspeed situation, the hydraulic buffer plays a crucial role in absorbing the excess energy and minimizing the impact on the elevator car and passengers.

Hydraulic buffers are essential safety devices in elevators, ensuring a gradual and secure stopping mechanism that contributes significantly to passenger safety and the overall reliability of the elevator system. Their design and functionality are paramount in preventing potential accidents and ensuring a safe transportation experience for passengers.
