Model QJJ30-4C mechanical type automobile lifter adopts motor driven mode and is operated under the electric control. When it’s operating, the star cycloid pin gear slows down and the lead supporting fork holds up the car wheels along with the upanddown movement of bracket to elevate the automobile. The machine has rational design,novelty structure and big lifting capacity and it is also firm and endurable and flexible in motion and can be fit for wide range of car models. The maintenance is also convenient for it. Since it adopts traveling operation, it can be used both indoors and outdoors and is the ideal automobile lifting device for the automobile manufacturing, repair and maintenance to increase production efficiency, enhance guarantee repair quality and improve the working environment.
This machine is mainly used for the lifting of all classes of passenger car and freight car below 20 tons in automobile manufacture and automobile repair. It can lift the automobile to appropriate height for the easy access to the bottom of automobile, which substitutes the traditional trench operation mode.
QJ: Automobile lifter

Basic structure and working principle
This machine adopts motor driven mode and mobile supporting roller elevation.The
Machine is composed of under carriage, upright post, reduction drive, lead screw nut,
bracket, fork support, supporting fork, electromagnetic clutch and electric control
Cabinet,etc.When the lifter operates under the electric control, the reduction drive
drives the lead screw turn and the screw nut drives the bracket and the supporting
roller on the fork support going up and down. As the diameters of the car wheels
vary, the supporting fork can be adjusted according to the size of the car wheel to fit
for the lifting of different car models.
Safety protection system
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 doesn’t 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.
