Product Description

Elevator Safety Components Oil Buffers for Safe and Controlled Deceleration in Overspeed

An elevator oil buffer is a critical safety device designed to absorb and dissipate the kinetic energy of a descending elevator car or counterweight in the event of an overspeed or free-fall scenario. Installed at the bottom of the elevator pit, it ensures a controlled deceleration, preventing abrupt stops that could endanger passengers or damage the elevator system.

Working Principle
The oil buffer operates based on hydraulic principles. When the elevator car or counterweight strikes the buffer's piston, it compresses, forcing oil through small orifices inside the cylinder. The restricted flow of oil creates resistance, converting kinetic energy into heat and gradually slowing the descending mass. Unlike spring buffers, which rebound, oil buffers are non-rebound types, meaning they remain compressed after impact and require resetting by maintenance personnel.

Types of Oil Buffers
Non-Energy Accumulation Type: Relies solely on hydraulic resistance to decelerate the elevator.
Energy Accumulation Type: Combines hydraulic resistance with a spring mechanism for additional energy absorption, suitable for higher speeds.
Key Features
Speed Compatibility: Typically used for elevators with speeds exceeding 1 m/s.
Load Capacity: Designed to handle specific weight ranges, ensuring optimal performance.
Durability: Constructed from high-strength materials to withstand repeated impacts and harsh conditions.
Maintenance: Requires regular inspection of oil levels, seals, and piston movement to ensure reliability.

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.
