Semi-trailer

Dump Semi-trailer is suitable for the transportation of bulk and scattered goods such as coal, ores, and construction materials. Dump semi-trailers can be divided into two categories according to their uses: one is heavy-duty and super-heavy dump trailers for off-highway transportation, which mainly undertake transportation tasks such as large-scale mines and projects, and are usually used in conjunction with excavators. The other type of light and medium-sized ordinary dump trailers for road transportation are mainly responsible for the transportation of loose goods such as sand, soil, and coal, and are usually used in conjunction with loaders.
1. The carriage adopts rollover and self-unloading methods, which can effectively improve the transportation efficiency of bulk cargo transported by the loader. 2. The frame and the longitudinal beam of the carriage are welded with high-quality manganese plates, and the cargo box has two types: dustpan and rectangle. It has high strength, strong lifting force, good rigidity and toughness, strong bearing capacity and no permanent deformation. 3. Sophisticated craftsmanship: The main components are processed by advanced equipment, the longitudinal beams are fully automatic submerged arc welding, and the axles and leaf springs are precisely assembled by an assembly machine.

The low-bed semi-trailer has no fence in the on-board part and is widely used, mainly used 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 live gooseneck type. The height of the web is from 400mm to 550mm, the longitudinal beam is welded by automatic submerged arc welding, the frame is treated by shot peening, and the cross beam penetrates the longitudinal beam and is welded as a whole. It is composed of a series dry leaf spring and a suspension bearing, with a reasonable structure, strong rigidity and strength, and is used to support the load and buffer the shock. Low flatbed semi-trailers are usually used to transport heavy vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machines, forestry machines, agricultural machines (such as excavators, bulldozers, loaders, pavers, cranes, etc.) and other heavy loads, the lower the center of gravity, the better the stability and safety, the better the ability to transport super high loads and pass overhead obstacles. Low-bed semi-trailer structure and loading The low-bed semi-trailer usually adopts a concave beam (or well-type) frame, that is, the front section of the frame is a gooseneck (the traction pin in the front section of the gooseneck is connected to the traction saddle on the tractor, and the gooseneck is connected to the traction saddle on the tractor. The rear end is connected with the semi-trailer frame), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including wheels). When loading mechanical equipment on a low-bed semi-trailer, it is usually loaded from the rear end of the semi-trailer, that is, by moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fixing the mechanical equipment on the semi-trailer. superior. The walking structure of the low-plate semi-trailer is made of high-strength international steel material, and the whole vehicle is light in weight, and ensures its anti-torsion, anti-vibration, anti-bump ability, and meets the bearing capacity of different road surfaces.
