Low Noise For Test Spring And Passenger Hydraulic Oil Elevator Buffer

The hydraulic oil buffer is a critical safety device installed at the bottom of elevator pits, designed to absorb and dissipate kinetic energy in the event of an uncontrolled descent or over-speed condition. It provides a controlled deceleration to safely stop the elevator car or counterweight, preventing structural damage and ensuring passenger safety.

Working Principle

• When the descending car or counterweight strikes the buffer, a piston compresses hydraulic oil through precisely calibrated orifices.

• The oil's resistance converts kinetic energy into heat, ensuring smooth, gradual stopping without rebound.

• Once activated, the buffer requires manual resetting and inspection before the elevator can resume operation.

FAQ
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.
