Standard Drop-Deck Semi-Trailer

Jinfeng China Standard Drop-Deck Semi-Trailer is a special vehicle designed for large-scale and ultra-high cargo transportation. With scientific design and strict craftsmanship, it has become a benchmark product in the industry. The core highlights of the product focus on three key characteristics: concave beam structure, sunken cargo platform, and height limit adaptation. The concave beam structure adopts an I-shaped longitudinal beam design and a stepped frame layout, which greatly improves the rigidity and strength of the vehicle body, effectively distributes the cargo weight, and avoids body deformation during transportation; the sunken cargo platform design makes the no-load ground clearance of the cargo platform more advantageous, significantly reducing the overall transportation height of the cargo. Combined with the reasonable force-bearing of the concave beam structure, it can not only easily carry heavy cargo but also flexibly adapt to various height-limited scenarios such as urban roads, rural roads, and highway sections, completely solving the problem that traditional semi-trailers cannot pass due to ultra-high height.

The entire product is made of high-strength steel, with key parts reinforced. It has excellent load-bearing performance and can adapt to the transportation of various heavy cargoes of 20-150 tons. The whole vehicle is optimized through advanced computer-aided design software, balancing light weight and load-bearing capacity, reducing fuel consumption while improving transportation safety. The vehicle body is equipped with a three-axle balanced suspension, and a mass balance block is installed between the front and rear leaf springs to ensure balanced force on the front and rear axles, improve driving stability, and reduce the risk of cargo damage due to jolting. At the same time, it is equipped with a complete braking and protection system, fully complying with relevant national standards to ensure the safety of the entire transportation process.

Application scenarios

In terms of application scenarios, Jinfeng China Standard Drop-Deck Semi-Trailer has a wide range of uses, mainly adapting to the large-scale cargo transportation field. It can be used to transport construction machinery and equipment such as excavators, bulldozers, and cranes, heavy objects such as large steel, bridge components, and power station equipment, as well as special cargoes such as highway construction equipment and large tanks. It is widely used in industries such as construction engineering, mining, power construction, and logistics transportation. Whether it is long-distance cross-regional transportation or short-distance construction site transfer, it can efficiently complete transportation tasks relying on the advantages of height limit adaptation and stable load-bearing performance, especially suitable for transportation scenarios with many height-limited road sections, greatly improving transportation efficiency and reducing transportation costs.

Product Manufacturing Process

The product manufacturing process strictly follows standardized production specifications to ensure the quality of each product meets the standards.

Step 1: Design and material preparation. The technical team completes the optimized design of drawings according to product standards and procurement needs, selects high-strength steel that meets the standards, and accurately cuts components such as main beams, side beams, and webs through CNC plasma cutting equipment to ensure that the dimensional error is controlled within a reasonable range;

Step 2: Girder welding and correction. After assembling the cut webs and flange plates, the I-shaped steel girders are welded by automatic submerged arc welding process. After welding, strict correction is carried out to calibrate the horizontal error of the double girders to avoid body skew;

Step 3: Frame assembly. Weld the side beams, traction pins, and suspension system, strictly control the suspension installation dimensions to ensure vertical accuracy, prevent later tire wear, and at the same time weld the gooseneck part and add reinforced steel plates to improve the overall strength;

Step 4: Cargo platform laying and welding. Lay the bottom plate flat and weld it to the frame as a whole to ensure that the cargo platform is firm and free from loosening hazards;

Step 5: Surface treatment and painting. Clean the welding slag and shot blast the vehicle body to remove rust and impurities, then spray anti-rust primer and topcoat to improve corrosion resistance and appearance texture; Step 6: Final assembly and inspection. Install and debug accessories such as axles, tires, and braking systems, conduct comprehensive inspections on vehicle performance, load-bearing capacity, braking effect, etc., and leave the factory only after passing the inspection. The production details are controlled throughout the process, demonstrating Jinfeng China's quality craftsmanship.
