Product Description:

The excavator semi trailer uses a concave beam frame with a very low center. Its center of gravity is low. A mass balance block is installed between the front and rear leaf springs inside, so that the body is evenly stressed, and it can transport ultra-high cargo stably and safely. The I-shaped longitudinal beams make the frame strong and stiff.

Due to the simple structure and easy disassembly, many large-scale equipment and steel, and various types of mechanical construction. Low-level trailers have a wide range of operations: such as tractors, rail lanes, various machinery such as excavator pavers.

Heavy load trailer generally have the following structure. Frame and axles The axles are mostly collinear with two axles, that is, there are two axles on the same axis, which are also called two axles. The common monolithic flatbed trailer has 2 to 7 axes.

There are 4 tires on one axle, and 8 tires on one axis. So 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 radial rim tires with small diameter and large load capacity are generally installed. Each tire can withstand a load of about 4 tons under low-speed operating conditions. The frame adopts a welded structure of high-strength alloy steel box section. It is widely used for large enterprises.
