What is Heavy Duty Low Bed Semi Trailers?

Heavy-duty low-bed semi-trailers are used for trailers for oversized and overweight shipments. The basic form of heavy trailer is a single flatbed trailer. It generally has the following structure. Frame and axles The axles are mostly collinear with two axes, that is, there are two left and right axles on one axis, which is also called a two-axis train. Common single-bed trailers have 2 to 7 axes. There are 4 tires on one axle, and 8 tires on one axis. Therefore, the width of the whole car can reach more than 3 meters. In order to reduce the center of gravity of the vehicle, steel radial wide rim tires (see automobile tires) with small diameter and large load capacity are generally installed, and each tire can bear a load of about 4 tons under low-speed running conditions. The frame uses a welded structure with a high-strength alloy steel box section. Generally, a single-axle trailer with five axes and two axes can carry more than 100 tons.

What is Gooseneck Semi Trailers?

Goose-neck semi-trailer truck cargoes are also very extensive, suitable for the transportation of various steels for various mechanical equipment, large objects, highway construction equipment, large tanks, and power station equipment. The series of semi-trailers have flat, concave beam and exposed tire structure. The longitudinal beam adopts straight or gooseneck type. Its frame is stepped and the longitudinal beam section is I-shaped. It has high rigidity and high strength. The main plane of the frame cargo platform is low, which ensures the stability of transportation and is suitable for carrying large-scale equipment and steel of various types of construction machinery. A three-axis balanced living rigid suspension is adopted, and mass balance blocks are installed between the front and rear leaf springs, so that the deflection of the front and rear leaf springs can be changed by an equal amount, and the rear axle force can be balanced. It has a wide range of uses, high efficiency and quickness. The entire vehicle adopts advanced computer-aided design software to optimize the design. It is flexible and diverse. The frame bearing surface is designed according to user requirements to meet the transportation of various special goods.

17.5m 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, road pavers, Cranes, etc.) and other heavy-duty goods, the lower the center of gravity, the better the stability and safety, the stronger the ability to transport ultra-high cargo and pass overhead obstacles. Low slab semi-trailer structure and loading. Low-floor semi-trailers usually use a recessed beam (or well) frame. The front section of the frame is a gooseneck (the traction pin at the front section of the goose neck is connected to the traction saddle on the tractor, and the back end of the goose neck is connected to the semi-trailer frame Connected), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including the wheel). When loading machinery and equipment on a low-bed semi-trailer, it is usually loaded from the rear end of the semi-trailer, that is, by moving the machinery from the rear wheel frame or removing the wheels, and then fixing the machinery to the semi-trailer on.
