2) Whether the turbine pair and the coupling work normally.
3) Whether the guide rolling wheel and support rolling wheels work normally.
4) Whether pinion and the rack work normally.
5) Whether position limited structure on the safety device work normally (when
inspection the electric circuit should be switched off).
SAJ serials pinion and cone progressive safety device is the most important safety device in the pinion and rack builders hoist, which can prevent 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 presided 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 of Construction, and also won the Shanghai excellent new product prize.
