 Safety protection system for 20/30t heavy duty bus lifting machine

1. The steel safety nut is set under the working screw nut(see operation nut safety mechanism diagram).When the operation nut is broken suddenly due to wear or other reasons, the safety nut under the operation nut will hold up it. With the steel ball rolling device, when the operation nut breaks down and falls on the safety nut, the operation nut and elevating screw nut body will run idle with the play of steel ball doesnt go up and down to give a safety lock and keep the lead screw free from damage.

2. At both the upper end and lower end of each upright post is set the lifting stroke stop device to ensure the automatic stop of the over travel when running.

3. The electromagnetic clutch is installed on the top of the motor shaft of the speed reducer to ensure the quick braking when the lifter shuts down in the rising or descending of the lifter.

4. The transport wheel has the hydraulic rising and lowering unit. When the lifter travels, pull the hydraulic jack pressure lever to make the undercarriage off the ground for easy traveling. When lifting, step the jack oil drain pedal to fall the undercarriage to the ground to ensure safe, steady and unshifted lifting.
