Maintenance tips for low-bed semi-trailers

How to extend the service life of the car? This is a big problem for many drivers. The key is to maintain the excellent workmanship of the car, which is more conducive to extending the service life of the car. In fact, its information is broader, including professional knowledge such as car beauty and maintenance.

Low-bed semi-trailers are usually used to transport super-heavy vehicles (such as trucks, buses, special-purpose vehicles, etc.), rail vehicles, mine machinery and equipment, forestry machinery, and engineering machinery and equipment (such as excavators, excavators, assembly and cutting machines, paving machines) , lifting equipment, etc.) and other light-loaded goods, the lower the center of gravity, the better the stability and safety, and the stronger the ability to transport high-height goods and overcome overhead obstacles. Low-bed semi-trailers usually use a concave beam (or well-shaped) frame, which has a gooseneck in the front half of the frame (the traction belt pin in the front of the gooseneck is connected to the traction belt saddle on the truck, and the back of the gooseneck is connected to the half The trailer frame is connected), the middle area is the cargo platform (the lower part of the frame), and the back is the side frame (including the wheel).

When carrying equipment on a low-bed semi-trailer, the equipment is usually carried on the back of the semi-trailer, that is, by moving the equipment from the rear side frame or removing the wheel, and then fixing the equipment on the semi-trailer. On the trailer.

Low-bed semi-trailers are widely loaded and are suitable for transporting various industrial equipment, large and medium-sized items, highway construction equipment, heavy storage tanks, power equipment and various stainless steel plates.

1. The series of low-bed semi-trailers have platform type, concave beam type and tire leakage type structure, and the side beams adopt vertical type or gooseneck type. The frame is a stepped type, and the side beams have an I-shaped cross-section, which has the characteristics of high bending stiffness and high compressive strength. 2. The main plane of the frame cargo platform is low, which ensures the stability of the transportation industry and is suitable for transporting various engineering machinery, equipment and materials.

3. Use a three-axis balanced, two-axis balanced or steel suspension system, with quality weights between the front and rear left and right leaf springs, which can equalize the deflection values of the front and rear left and right leaf springs, so that the successive bearings are stressed. balance etc;

4. The low-bed semi-trailer product series can be used to transport various industrial equipment, large and medium-sized items, highway construction equipment, heavy storage tanks, power equipment and various stainless steel plates. It has a wide range of uses and is convenient. The entire vehicle uses professional auxiliary design and drawing software to carry out various reliability design forms. The load-bearing surface of the frame is designed according to user needs to achieve the transportation of various special products.

The main categories of low-bed semi-trailers are: two-axle high-low flat-bed semi-trailers, two-axle four-axle high-low flat-bed semi-trailers, three-axle high-low flat-bed semi-trailers, three-axle six-axle high-low flat-bed semi-trailers. The load capacity of low-flat semi-trailers depends on the axle load and tire size. The load capacity of low-flat semi-trailers is also different. The greater the axle load, the greater the load capacity, and the load range is between 20-150 tons. Depending on the axle load and tire size, the load capacity of low-flat semi-trailers is also different. The greater the axle load, the greater the load capacity, and the load capacity range is between 20-150 tons.

1. Car body maintenance

Vehicle body maintenance is also commonly called semi-trailer beauty care. The main purpose is to eliminate various oxidation and corrosion on the outside and inside of the vehicle body, and then perform maintenance to highlight the "beauty" of the vehicle as much as possible. It mainly includes: paint maintenance, seat cushion and blanket maintenance, bumper and skirt maintenance, dashboard maintenance, electroplating processing maintenance, leather products and plastic maintenance, tire and rim warranty, car windshield maintenance, car chassis maintenance, automobile Engine surface maintenance, etc.

2. Car maintenance

Car body maintenance is to keep the car youthful forever, and the purpose of car maintenance is to ensure that the car can be driven for hundreds of thousands of kilometers without major repairs, ensuring that the car is in the best working condition. It mainly includes: lubrication system, gasoline and diesel system, refrigeration system, braking system system, motorcycle carburetor (injector) maintenance, etc.

3. Car body renovation

Such as diagnosis and treatment of deep scratches, repair of multi-material bumpers, defect repair of wheel rims (covers), material renovation of leather products and fiber, color renovation of automobile engines, etc. How to extend the service life of light-weight low-bed semi-trailers with professional knowledge on maintenance.

Semi-trailer maintenance is divided into two categories: scheduled maintenance and non-scheduled maintenance. Scheduled maintenance includes: daily maintenance, first-level maintenance, and second-level maintenance; non-scheduled maintenance includes: running-in time maintenance and periodic maintenance. The main tasks of car maintenance include cleaning, inspection, tightening screws, adjustment and lubrication. However, with the development trend of science and technology and automobile industry production, various professional processes led by electronic computers are widely used in automobiles, which will gradually move toward intelligent systems in the future. Therefore, the specific content of semi-trailer maintenance has been given new meaning.

Semi-trailer maintenance is a highly professional and complicated work. It is very difficult for the driver to do it alone, and it must be carried out by an automobile maintenance company. Nowadays, there are also some automobile maintenance companies in China that cling to the traditional maintenance concept. Maintenance equipment and tools are old and outdated, and maintenance methods are still the same, which are not suitable for the needs of modern progress. In addition, the service level of some maintenance companies is worrying. In order to make huge profits through "black box work", the old ones are replaced with new ones and the inferior ones are replaced during maintenance. Maintenance fees and replacement parts fees are skyrocketing. Therefore, drivers are reminded to choose a maintenance company with strong technical strength, reliable service level and good reputation when maintaining their cars, and do not find it inconvenient or cost-effective to not maintain the semi-trailer, lest the gain outweighs the loss.
