What does the front of the trailer depend on the container?


When the tractor is retrograde, the tractor and the semi trailer center line strive to be consistent, and the deviation of the two car center line is limited to 40 mm. Tractor saddle mouth aligned traction pin after slowly reversing until you hear a "click" sound, the locking block back, then the tractor and semi trailer traction success.
1, adjust the support leg, so that the semi-trailer traction slide and traction saddle height to adapt, generally in the semi trailer traction slide plate than tractor traction saddle upper plane center position is 1-3 cm low, be careful not too high. Otherwise, not only can not connect, but also damage the traction seat, traction pin and related parts.2. Control the locking mechanism of the traction seat so that the locking block opens and becomes free.
The front and the trunk of the trailer are connected by the saddle and the traction pin. Before connecting, carefully check whether there is enough grease on the surface of the saddle of the tractor, whether there is any foreign body on the traction pin of the semi-trailer or the traction slide board, and ensure the cleanness of the traction slide plate.
Check whether the locking block of the traction seat locks the traction pin and whether the locking is firm.Connection of traction head and Trailer1. The two trachea joints on the traction head (commonly known as handshaking) are attached to the two tracheal couplings on the trailer. At this time, the air supply pipeline of the tractor is connected with the air supply pipeline of the semi-trailer, and the control pipe of the tractor is connected with the control pipe of the semi-trailer (attention to the color of the joint: to install with the hue, not to install the reverse).2, after the gas connections are connected, the semi-trailer on the tractor shall be unscrewed, and the gas path shall be connected with the separation switch so as to be in a ventilation state. Otherwise, the gas supply system of the semi-trailer can not be supplied, and the braking system can not work.3. Start the engine, observe the pressure gauge in the cab, and increase the pressure in the storage tank of the tractor and semi trailer to the required pressure. Check the gas path for leaks and check that the brake system is functioning properly.4, seven tractor connection socket cable plug is inserted into the front end of the semi-trailer until seven in the clamping block on the bolt.5, check whether the electrode joint well, confirm the side lights, taillights and other lights are working properly. Hang up and confirm again after the half of the instruments. After the work is normal, you can start.
