Description :

　　The new GB7258 "Technical Conditions for Safety of Motor Vehicle Operation" officially implemented on January 1, 2018 states that "the rear axle of dangerous goods transport trucks with a total mass greater than or equal to 12000kg, all dangerous goods transport semi trailers, as well as three axle rail type and compartment type semi trailers, should be equipped with air suspension. ”What are the advantages of air suspension in obtaining clear policy support? The advantages of using air suspension for semi-trailer have been summarized for everyone's reference. The advantage of air suspension is that it reduces the impact of liquid flow on the tank during turbulence, protecting the safety of freight transportation; Reduce tire wear, lower fuel consumption, etc. The use of air suspension in China has accumulated rich practical experience. With the development of technology, air suspension for dangerous goods skeleton semi trailers has become an indispensable standard for high-end heavy-duty trucks and special vehicles. Small amplitude of turbulence: By adjusting the air spring, the height of the cargo box can be ensured to be constant, and the liquid shaking caused by turbulence can be reduced, reducing the impact on the tank, protecting the safety of freight transportation, and improving the service life of tank trucks.

　　The Shandong Liangshan Trailer Series lightweight semi-trailer products have been on the market since 2013, continuously optimizing their design and gaining recognition from customers, leading the trend of lightweight design in the industry. The lightweight 13 meter semi-trailer model is known as a classic product in the vehicle industry. Shandong Liangshan Semi trailer Manufacturing Co., Ltd. has been focusing on the design and manufacturing of commercial vehicles and special vehicles for more than 20 years. It is a specialized semi-trailer and special vehicle production enterprise, a qualified semi-trailer export enterprise, and uses submerged arc welding for welding. The entire vehicle body is made of imported lightweight steel, which has the advantages of high strength, good resistance, and good fatigue resistance. The CO2 shielded welding process ensures that the welding is beautiful, firm, and durable. The CO2 gas inverter welding is used, and the entire frame is shot blasted to make the vehicle more beautiful.

　　The low flatbed semi-trailer has dimensions ranging from 9.6 meters to 10 meters, 11 meters to 12 meters, 13 meters to 13.75 meters, 16 meters, and 3 meters. It can be equipped with hydraulic ladders and is mainly used for transporting large items. Low flatbed semi-trailer type editing: The main types of low flatbed semi-trailer include: two axle high and low height, two line four axle high and low height, three axle high and low height, three line six axle high and low height. Low flatbed semi-trailer is also widely used for cargo transportation, suitable for various mechanical equipment, large objects, highway construction equipment, large tank bodies, power plant equipment, and various steel materials.

　　Air suspension transportation is smoother, with almost no change in the vehicle's center of gravity during operation, good axial and radial stability, and safer and more reliable driving. Adopting a squat braking system effectively avoids the forward leaning impact of the vehicle during emergency braking. Brakes and their operating devices: The semi-trailer adopts a dual tube pneumatic braking system and is equipped with an anti lock braking system (ABS). The driving brake system mainly consists of air joints, inflation pipelines, operating pipelines, emergency relay valves, air reservoirs, brake chambers, and wheel brakes. The parking brake is controlled by an energy storage spring brake system, and the wheel brake also serves as the parking brake. Use this device when parking or on a slope. 3. Axle and wheel: The suspension system is equipped with three identical axle assemblies. The axle is a square tube axle, with a platform for installing steel plate spring suspension and a bracket for installing brake chambers on the axle body. The axle head is used to install wheels, hubs, brakes, etc. 4. Supporting device: In order to ensure reliable parking of the semi-trailer after it leaves the index vehicle, two supporting devices with left and right linkage or left and right single action are installed at the front end of the frame. It consists of a screw transmission mechanism, a bevel gear transmission mechanism, a dual speed gearbox, a transmission rod, an operating handle, etc. When the handle is pushed in, rotating it can achieve high-speed lifting, and when the handle is pulled out, rotating it can achieve low-speed lifting. After the base touches the ground, only low-speed gear can be used for lifting. The air joint of the inflation pipeline is connected to the tractor air reservoir, and the air joint of the operation pipeline is connected to the brake valve of the tractor. When the semi-trailer brakes, all brake chambers act simultaneously. When the driver steps on the brake pedal, the various brake chambers of the semi-trailer are activated to achieve normal foot braking. When the charging pipe leaks or bursts, or when the tractor suddenly disengages from the semi-trailer while driving, causing the pipeline to detach, the semi-trailer can automatically brake. When the car train stops and the tractor and semi-trailer are separated, the semi-trailer can brake on its own. If the parking time is short, the parking brake does not need to be used. To prevent accidents from happening.
