Product Description
The safety devices 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.
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.
