Two section hydraulic ladder low flatbed trailer factory scene real shot engineering machinery flatbed truck manufacturer
The 13m 13.75m three axle low flatbed semi-trailer has no railing on the vehicle body and is widely used, mainly for medium and long-distance freight transportation. The series semi-trailer frame adopts a through beam structure, and the longitudinal beam adopts a straight movable goose neck 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 penetrates the longitudinal beam and is welded as a whole. Composed of a series of dry plate springs and suspension supports, the structure is reasonable, with strong rigidity and strength, used to support loads and mitigate impacts. Low flatbed semi-trailer is 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-duty goods. The structure and loading of low flatbed semi-trailer usually adopt a concave beam (or well type) frame, with the front part of the frame being a goose neck (the traction pin in the front part of the goose neck is connected to the traction saddle on the tractor, and the rear end of the goose neck is connected to the semi-trailer frame), the middle part being the cargo platform (the lower part of the frame), and the rear end being the wheel frame (including the wheels)
