Our main products are Pessenger hoist and spare parts like the motor reducer , mast section , safety device , 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.Safety Device for Construction Building Hoist,Anti- fall safety device.The reason can be safely lift construction manned loading operation, mainly due to its anti-fall safety device is equipped, greatly improving the safety factor. At present, the construction site is widely used rack and pinion construction hoist people generally equipped with dual-use goods is tapered drum gear progressive anti-fall safety device.

SAJ type anti-falling safety device is one typical model of building hoist , which can prevent the cage running overspeed, and effectively reduce the cage dropping accident. , and is designed for prevent building hoist cages or counterweight from falling. It is made up of gear, centrifugal speed limiter device, cone drum and brake device.
 
Feautures:
1. Reasonable structure
2. High precision machining
3. Good interchangeability
4. Open speed is stable
5. Speed calibration error is small
6. Smooth braking and light weight
7. Internal system drum and centrifugal speed limiting device adopt forging die processing, which can prevent the hidden danger brought by traditional pouring process.
8. Using domestic leading enterprises of sliding bearings and the Great Wall high-quality grease, The gear shaft increases the oil groove, and increasing silencing shock absorber, so greatly reducing the incidence of noise
9. It adopts the spring parts and friction pieces professionally produced in China to ensure the stable braking moment and opening speed of the products.

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.
