On February 10, 2022, the rotary lock flatbed trailer
A full trailer generally consists of a frame, body, traction device, steering device, suspension, walking system, braking system, signal system, etc.? The upper wing surface of the longitudinal beam of the straight beam frame is straight. Its advantages lie in the flat bottom plate of the trailer cargo platform, simple manufacturing process, generally high ground clearance, and good longitudinal passability. Heavy duty flatbed trailers are designed to meet their structural and operational requirements. The frame is mainly composed of main beams, cross beams, support beams, and side beams. The load of the entire vehicle is transmitted to the ground through the support beams between the crossbeams, suspension, wheel axles, and wheels. The main beam, support beam, and side beam of the frame are welded components with box sections, which have high torsional stiffness. The crossbeam connecting the main beam extends to both sides and is a variable cross-section I-shaped welded structure with high lateral bending strength.
