1. Use

The equipment for the operation of a vehicle frame is called a group of carriage units. The full set of equipment consists of 6 sets of mobile rack cranes and 2 consoles, and the console can realize the function of 3 vehicles with synchronous racks.

2. Main functions

1) Synchronous lifting and racking operations for a single vehicle;

2) Perform synchronous lifting and racking operations on the vehicle (one unit) with the three-cart hook in the connected state;

3) The mobile rack crane should be equipped with running wheels, which can be manually moved on the ground in the workshop and can also be lifted by cranes.

4) It has functions such as running elevation display, automatic over-adjustment, and over-limit shutdown alarm.

5) Simultaneous lifting and lowering of the same group of carriages can be stopped at any height in the lifting and lowering process to carry out the work under the vehicle.

6) The control system has a perfect interlock control function to ensure the coordinated control of the synchronous lifting of the vehicle body.

3. Main structural composition

The mobile lifting jack consists of a frame, a driving device, a bracket, a walking device, and an electrical control and operating system.

4. Main Technical Parameters

1) Four sets of total lifting capacity: 64 tons

2) Single machine rated lifting capacity: 16 tons

3) Lifting speed:≤300mm/min

4) The supporting surface of the head from the rail surface (in the lowest position): no more than 700mm

5) Effective lifting stroke is not less than 1500mm

6) Working voltage AC 380V±10% 50Hz

7) The power of each carriage is not more than 4kw

8) Synchronization accuracy (per group)≤±4mm

    The same car height difference 4mm

    Height difference between any two cars 8mm

9) Noise level The noise of our equipment is≯65dB, which is in line with the requirements of labor insurance regulations in the national maintenance workshop.

10) The weight of single machine is about 3 tons

11) Dimensions (length×width×height) 1250*950*2950mm

12) Equipment service life 30 years
