Elevator Safety Parts Lift PU Buffer Elevator Polyurethane Buffer Bumper

Working principle: Polyurethane buffers utilize the special micro-porous bubble structure of polyurethane material to absorb energy and cushion. During impact, it acts like a spring with multiple air cushions for damping When the elevator cabin or counterweight is impacted for various reasons, the polyurethane buffer absorbs and dissipates the impact energy through its compression deformation, converting impact potential energy into elastic potential energy, thus acting as a decelerator, buffer, and energy absorber, reducing harm to passengers or goods inside the cabin. 

 Performance features 
 Light weight: Compared to other types of shock absorbers, such as metal spring shock absorbers, polyurethane shock absorbers are significantly lighter, making them easier to install and maintain. 
 Easy to install: no complex installation equipment or technology required, can be directly installed on the side of the counterweight and directly below the side of the cabin in the elevator pit. 
 No maintenance: Under normal use, the polyurethane buffer does not require regular maintenance, reducing the elevator's maintenance cost. 
 Good cushioning effect: It can effectively absorb and dissipate the impact energy generated by the elevator cabin or counter weight collision, making the elevator's deceleration process smoother and reducing the impact on the elevator and passengers. 
 Good shock and compression resistance: can withstand multiple high-intensity impacts and quickly recover to its original state after compression, maintaining excellent cushioning performance. 
 Good explosion resistance: no noise or sparks during cushioning, suitable for places with explosion requirements. 
 Applicable range: According to relevant standards, when the elevator speed is 1m/s, the elevator buffer can choose energy storage type buffers, which include polyurethane buffers. Due to the generally lower speed of home elevators, they usually use polyurethane buffers.
