Anti Fall Safety Brake for Construction Building Elevator

Construction hoist elevator safety devicesSAJ30 40 50 60

SAJ serials pinion and cone progressive safety device is the most important safety device in the pinion and rack builders hoist, which can pvent the cage running over speed, and effectively reduce the cage dropping accident.

The safety devices developed by Shanghai Research Institute of Building Sciences has passed through the evaluation psided by the Ministry of Construction in 1989. The specialists at the meeting made a high appraisal of reasonable compact structure, stable action speed, highly accurate calibration, safe and reliable, braking smoothly and light weight etc. features of the safety devices.

The devices was recommended as hightech products developed in National Eighth Five Year Plan by the Ministry ofConstruction, and also won the Shanghai excellent new product prize.
