Buffers | Elevator Wiki | Fandom

A buffer is a device designed to stop a descending car or counterweight beyond its normal limit and to soften the force with which the elevator runs into the pit during an emergency. They may be of polyurethane or oil type in respect of the rated speed. There are two principal types of buffers in existence: Energy accumulation: accumulate the kinetic energy of the car or

ELEVATOR IMPACT PROTECTION

The requirement for elevator buffers fall into two categories depending on the type of buffer. 1.

What Are Elevator Buffers

An elevator buffer is a mechanical accessory placed at the base of an elevator shaft. Its main intended use is safety. They are to act as shock absorbers. They counteract the effect of the energy produced by a falling elevator car. They serve the purpose of ensuring that the occupants of the elevator car or the car are safe from any potential harm.

When the elevator car or counterweight hits the spring buffer, the spring will be compressed and deformed, converting the impact energy into elastic potential energy for storage. As the spring is gradually compressed, the reaction force it generates will gradually increase, thereby slowing down the impact speed of the elevator.

What Is an Elevator Buffer?

What is an elevator buffer?

Elevator buffers are mechanical devices installed at the bottom of elevator shafts. Their primary function is to absorb the kinetic energy generated during emergency situations, such as an overspeed condition or a sudden stop. By absorbing this energy, elevator buffers protect the elevator car and its occupants from potential harm.

What are the requirements for elevator buffers?

The requirement for elevator buffers fall into two categories depending on the type of buffer. Energy accumulation buffers: These can take the form of simple mechanical springs or polymer buffers which store the absorbed energy of the impact in the form of strain energy.

What are the different types of elevator buffers?

According to different working principles and design characteristics, elevator buffers can be divided into several main types. Elevator buffers types mainly include energy-storage buffers and energy-consuming buffers. Polyurethane and spring buffers are energy-storage buffers, and hydraulic buffers are energy-consuming buffers.

What is a oleo elevator buffer?

Oleo elevator buffers are designed to protect people and equipment from forces generated from an impact resulting from equipment failure or operator error. Oleo has achieved this on most buffer types using hydraulic energy absorption systems combined with a gas return spring to give unsurpassed energy dissipation and recovery.

Why do elevators use polyurethane buffers?

Polyurethane has excellent energy absorption capacity and elasticity. It can quickly return to its original state when the elevator stops, releasing stored elastic potential energy, thereby reducing impact force. Polyurethane buffers are typically used for elevators with speeds less than or equal to 1 meter per second.
