JHQ Series Polyurethane buffer

The polyurethane buffer used in elevator

The polyurethane buffer used in the elevator may exert great flexibility of the chain of the high polymers under the impact.This will guarantee gentle and stable landing of the operator's cabin without noise or vibration to ensure the safety of equipment and life as the high flexibility and defensibility of the chain of the high polymers.

The polyurethane buffer used in JHQ elevator is one of the non-linear buffers as per the updated international standard En81-1 in 1998. It is designed in terms of modern moving load experiment that takes lead in domestic market.As thorough analyses are performed to deformation,velocity,deceleration,absorption,buffering time under the moving load impact of the non-lincar clastomer,it is guaranteed that the production will be realistic in practice.The polyurethane buffer has been pass the teat set by the National Elevator Quality Surveillance Center.

How do you choose a buffer? First,you should determine the rated speed of requirement in the elevator design and it in the cushion stroke,as the two performances are key omportant to safeyt and effects.As soon as the reted speed and cushion stroke have been determined,the number of buffers will be decided in accordance with requirement of design and the loading bearing quality.
