Steps for Hanging up a Semi-trailer

1. Secure the semi-trailer to prevent it from sliding.

Use skids to fix the tires in the front and rear directions to prevent them from sliding. Do not hang up on a sloped place. It is best to hang up on a flat road.

2. Make sure the hitch is pre-hitched.

The handle is pulled out, the panel grease lubrication and other maintenance operations are completed, otherwise the traction seat is opened.

 

3. Check the height of the semi-trailer.

The ideal height of the skateboard must be the same as or not lower than 50mm of the height of the tow seat panel.

4. Drive the tractor back toward the semi-trailer, and stop when the towing seat touches the front end of the semi-trailer. In the case of air suspension, the airbags should be fully inflated. Then get off the vehicle and make sure that the tow bar is at a suitable height, i.e. the height that it can lift the semi-trailer slightly when the tow bar enters directly under the semi-trailer.

To achieve the proper lift height, lift or lower the trailer by adjusting the height of the outriggers. Finally, slowly reverse the tractor until the traction seat is connected with the traction pin, and the locking mechanism is automatically closed.

5. Check the locking mechanism.
