Shandong Hongsheng Automobile Semitrailer Manufacturing Factory is a regular Liangshan Trailer Factory specializing in the production of all types of trailers and semi-trailers. Our technical staff taught us how to correctly connect the electric roads of tractors and semi-trailers. .
1. First, connect the two trachea joints (commonly known as handshakes) on the tractor to the two trachea joints on the semi-trailer. At this moment, the air supply pipe of the tractor is connected with the air supply pipe of the semi-trailer, and the control line of the tractor is connected with the control pipe of the semi-trailer (note the color of the connector: install with the same color, do not install it reversely).
2. After the gas connections are connected to each other, the semi-trailer air circuit on the tow truck must be uncoupled and disconnected to make it in a ventilated state. Otherwise, the gas supply to the semi-trailer brake system cannot be performed, and the brake system cannot work.
The main types of low-profile semi-trailer are: two-axis high and low flat semi-trailer, two-axis four-axis high and low flat semi-trailer, three-axis high and low flat semi-trailer, three-line six-axis high and low flat semi-trailer. The low plate load depends on the number of axes, the size of the tire, and the load of the low-profile semi-trailer. The greater the number of shafts, the greater the load, and the load range of 20 to 150 tons. According to the number of axles, the size of the tire and the load of the low-profile semi-trailer are also different. The greater the number of axles, the greater the load, and how the semi-mounted excavator transporter can complete the electrical connection . The load range is between 20-150 tons. Shandong Hongsheng Vehicle Special Purpose Manufacturing Co., Ltd. provides professional, comprehensive special car prices, semi-trailer pictures. Hongsheng Specialist sells all over the country, with professional direct sales centers, sales departments and online sales centers in major provinces and cities. The sales personnel cover all major provinces and cities in the country and provide door-to-door service for customers. Mainly produces 13-meter light low-profile semi-trailer, light weight low-level trailer, heavy-duty trailer, high and low high-low bridge flat semi-trailer, two-axis low flat semi-trailer, tire exposed excavator transporter, bulldozer transport semi-trailer, goose Neck-type low flat semi-trailer, 13-meter trailer tray, concave beam low flat semi-trailer, construction machinery transport semi-trailer .
3. Start the engine, observe the barometer of the cab, and increase the pressure in the air tank of the tractor and semi-trailer to the specified pressure.
4. Check for gas leaks and check that the brake system is working properly.
5. Insert the cable connector of the tractor into the seven-hole socket on the front of the semi-trailer until the card is seated on the seven-hole plug.
6. Check if the electrodes are well connected and confirm that the lights such as the taillights are working properly.
