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.

Descripción 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.

Features Inner brake drum and Centrifugal speed limiter replace the original casting processing which may cause the security risks. We use the forging die process. 2. We use the sliding bearing of the leading enterprises and the preferred Great wall high quality grease. We use the special oil groove in the pinion shaft and add the silencing anti-vibration mounting In the inner structure, which can reduce the incidence of noise greatly. 3. We use the specialized production of spring pieces and friction plates in China, which can ensure the products’ stable retarding torque and open speed, quick reaction and smooth brake.

Ordering information Indicating the model and calibrated tripping speed when placing order, the calibrated tripping speed (m/s) will be fixed according to the elevator’s running speed and the customers’ need.
