Dump Semi-Trailers
Dump semi-trailers are suitable for transporting bulk cargo such as coal, ore, and construction materials. Dump semi-trailers can be divided into two categories based on their use: heavy-duty and ultra-heavy-duty dump trailers for off-road transport primarily handle large-scale mining and construction operations and are typically used in conjunction with excavators. Light- to medium-duty dump trailers for on-road transport primarily transport loose cargo such as sand, gravel, soil, and coal and are typically used in conjunction with loaders. 1. The trailer features side- and rear-dump dumping, effectively improving the efficiency of loaders transporting bulk cargo. 2. The frame and longitudinal beams are welded from high-quality manganese plates. The cargo box is available in two sizes: dustpan and rectangular. They offer high strength, strong lifting capacity, excellent rigidity, and toughness, as well as a strong load-bearing capacity and resistance to permanent deformation. 3. Superior craftsmanship: Major components are manufactured using advanced equipment, longitudinal beams are welded using fully automatic submerged arc welding, and axles and leaf springs are precisely assembled using assembly machines. [1] Low-bed semi-trailer Low-bed semi-trailer has no sidewalls and is widely used, mainly for medium and long-distance freight transportation. The frame of the series semi-trailer is a through-beam structure, and the longitudinal beam adopts a straight gooseneck type. The web height ranges from 400mm to 550mm. The longitudinal beam is welded by automatic submerged arc welding, the frame is shot blasted, and the crossbeam is inserted into the longitudinal beam and welded as a whole. It is composed of a series of dry leaf springs and suspension supports. It has a reasonable structure, strong rigidity and strength, and is used to support loads and buffer impacts. Low-bed semi-trailers are usually used to transport heavy vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machinery, forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.) and other heavy-loaded goods. The lower the center of gravity, the better the stability and safety, and the stronger the ability to transport oversized goods and pass overhead obstacles. Lowbed Semi-trailers typically feature a concave beam (or well-shaped) frame, with a gooseneck at the front (the front traction pin connects to the tractor's saddle, and the rear end connects to the semi-trailer frame), a cargo platform (the lowest part of the frame) in the middle, and wheel carriers (including wheels) at the rear. When loading machinery onto a lowbed semi-trailer, it's typically done from the rear, either by moving the equipment from the rear wheel carrier or removing the wheels before securing it to the semi-trailer. The undercarriage of a lowbed semi-trailer is constructed of high-strength international steel, resulting in a lightweight vehicle with guaranteed resistance to torsional, vibration, and bumps, meeting the load requirements of various road surfaces.
Stake-type Semi-trailer

13-meter High-Stake-Type Semi-trailer
Stake-type semi-trailers feature a stake-type design for their cargo area. They are primarily used for transporting agricultural and sideline products and other light and bulky cargo. 1. The vehicle model and fence structure are designed based on the type of cargo being loaded. This allows for a minimal weight reduction under load conditions. The simple, adaptable structure allows for easy disassembly, reducing investment costs and increasing profitability for users. 2. Frame: A space frame structure is constructed by welding longitudinal beams and integral through-beam crossbeams. This provides balanced strength, rigidity, and toughness, ensuring a strong load-bearing capacity without permanent deformation. 3. All frames in this series of fence-type semi-trailers are through-beam structures, with longitudinal beams either straight or gooseneck. Web heights range from 400 to 500 mm. Longitudinal beams are welded using automatic submerged arc welding, and the frame is shot-blasted. Crossbeams are welded integrally to the longitudinal beams. 4. Suspension System: A new suspension system is employed, offering high strength and impact resistance. Loads are balanced across all axles, and the system's tie rod angles are optimally designed. This minimizes tire-to-ground friction during frequent bumpy rides, effectively reducing tire wear. Adjustable tie rods and wheelbase adjustability effectively prevent tire wear and tear. Container Semi-trailers
Container semi-trailers are semi-trailers with containerized cargo compartments. They are primarily used in logistics systems supporting ships, ports, shipping routes, highways, transit stations, bridges, tunnels, and intermodal transport. 1. They are specifically designed for transporting various containers. They are durable and durable. 2. Containers are used for transshipping cargo, allowing for direct loading at the shipper's warehouse and unloading at the consignee's warehouse. When changing vehicles or ships mid-transit, there's no need to remove the cargo from the container. 3. They offer rapid loading and unloading, allowing for convenient transfers from one mode of transport to another. 4. They facilitate loading and unloading, meeting individual customer needs. Customized tooling ensures consistent quality and reliable performance. Container semi-trailers are specialized trailers designed to transport containers. In the early days of container transportation, due to the small capacity and quantity of containers, conventional trucks were often used. Since the 1960s, with the rapid development of container transportation, various countries have developed specialized trucks specifically designed for transporting containers. The loading area of a container trailer is sized according to standard container dimensions, and twistlocks are installed at the four corners of the container's base to secure the container. These trailers are designed specifically for transporting containers. Twistlocks are installed at the four corners of the loading area to secure the container. They are commonly constructed in semi-trailer, full-trailer, and double-trailer configurations, with the semi-trailer being the most common. Semi-trailers are further divided into flatbed and skeletal types. The former has a flatbed platform and can also be used to transport ordinary, long, and bulky cargo. The latter lacks a platform, and the container is mounted on a chassis frame and secured with twistlocks, providing the semi-trailer's strength.
