Building Hoist Parts SAJ Anti Drop Device 65kN for High Speed Building Hoist/Construction Elevator
Safety Device for Buidling Hoist/Conctruction Elevator
SAJ safety device is compulsory part on the building hoist/construction in China. When the building hoist/construction elevator descends over the rated speed, the micro-switch inside the safety device will be activated to cut off the power of the building hoist/construction elevator. Together with the brake of the motors, the safety device's pinion stops the cart of building hoist/construction elevator's cart onto the mast section gradually, which is very critical to the safety system of the building hoist.
The life span of the SAJ series safety device is five (5) years, and it has to be tested every six (6) months after the first test during the installation of building hoist/construction elevator.
