Introduction of the Elevator brake

    Elevator brake

    Brake is one of the frequent movement of the elevator security components, it can make the elevator motor to stop rotating, with no power supply, and bring the car to effectively stop the workstatus of the elevator, the safe operation is closely related withbrake. That a large number of incident cases, one of the main causes of casualty accident elevator is the brake faults or itsdesign flaws, resulting in the elevator is out of race to the top,bottom, Dun vehicle, even shear phenomena. Therefore, it is very important to strengthen the safety inspection of elevator brake.

    1.Brake mechanical parts of common problems, safetyrequirements and test

    The  brake mechanical parts of common problems

The elevator brake mechanical parts of common problems.

     a.Stroke indicator and the movable indicator together, some manufacturers of the designers of the uniqueness of the stroke indicator installed the ill considered.

    b.long-term use cause brake shoes off, adhesive glue (somebrake is stuck not riveting).

    c.Rubber seal aging rupture, fall into the foreign body caused bybrake block.

    d.The electromagnet core rust, caused by brake block.

    e.The elevator core guide mechanism design is not reasonable,copper and iron core connecting place fracture, resulting in brakeblock.

    f.The elevator repair maintenance personnel on the brake inspection, maintenance method is improper.
