The SAJ 50/40 Safety Device for construction hoist anti-fall is important to ensure the safe operation of the construction elevator safety components. Construction elevator is running, when the cage due to failure caused by stall falling, anti-fall safety device start action and the brake torque is gradually increased, at a certain distance within the cage will stop smoothly on the rail frame,so as to ensure the safety of construction hoist or passenger hoist.
The SAJ 50/40 Safety Device is the most important safety device in the pinion and rack builder’s hoist, which can prevent the cage running over speed, and effectively reduce the cage dropping accident.
