Hydraulic Elevator Oil Buffer with 150mm Stroke Carbon Steel Construction for ≤1600kg Cabins

The Hydraulic Elevator Oil Buffer is a critical safety component designed for traction and hydraulic elevator systems, providing reliable end-stop protection and smooth deceleration during emergency or terminal stopping conditions. Engineered with a precision-machined carbon steel cylinder and high-grade piston assembly, this buffer operates on the principle of fluid displacement, converting kinetic energy into thermal energy through controlled oil flow, thereby ensuring a cushioned, jerk-free stop even at rated impact speeds.

Constructed with a corrosion-resistant epoxy coating, the buffer withstands harsh environmental conditions, including high humidity and temperature variations from –10°C to +80°C, making it suitable for both indoor and outdoor elevator installations. The unit is available in standard stroke lengths of 150mm, 200mm, and 250mm, with custom options upon request to accommodate varying car weights and travel heights. With a maximum impact capacity of up to 150 kN and a reset time of less than 120 seconds, it complies with EN 81-20 and ASME A17.1 safety standards.

Maintenance is simplified through a top-fill oil port and visible level indicator, allowing for quick fluid checks and refills without disassembly. Whether applied in high-rise commercial buildings or low-speed freight elevators, this hydraulic buffer delivers consistent damping performance, extends equipment service life, and enhances passenger comfort. Backed by rigorous factory testing and a two-year warranty, it offers a durable, cost-effective solution for modern vertical transportation safety systems.

1. Are the elevator wire ropes durable?

   The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won’t break at the same time.

2. Is it dangerous for power failure suddenly during the elevator running?

   If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.

3. Will us be hurt when it closed suddenly?

   In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.

4. How the elevator running?

   Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.

5. Is the escalator installation complicated?

   We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.

6. Do you have any cerifications?

   Yes, we do with ISO9001 / CCC / CE Certificates for u.
