Construction Hoist Safety Devices
Construction hoist safety devices work together to control overspeed, travel limits, overload conditions and unsafe cage or landing-door operation. Each device has a separate function and should be inspected as part of the manufacturer’s maintenance program.

Application occasions:
SAJ serials pinion and cone progressive safety devices are used in wire rope hoist ,hydraulic
hoist and rack and pinion hoist. The following introduces the applications of all kinds of series of safety device :
SAJ02-1.2 and SAJ08-1.2 safety device mainly used in small rack and pinion hoist ,such as wind power tower hoist ;
SAJ30-0.5is used in ultra-low speed of hoist ,such as lifting platforms;Customers can choose the type of safety devices
according to hoist rated lifting speed and load.Tripping Speed of safety devices is no more than 0.4m/s of the hoist’s rated speed.
The production of this product conforms to EN12159, EN12158, EN1495, GB26557-2011, and JG121-2000.
