Three axle low flatbed semi-trailer, excavator transport vehicle, hook plate ladder truck

Description :

　　Large equipment and steel, etc. Adopting three-axis balance, dual axis balance or rigid suspension, a mass balance block is installed between the front and rear steel plate springs, which can make the deflection of the front and rear steel plate springs change equally, and balance the force on the front and rear axles. Carbon trioxide gas shielded welding, the entire frame is shot blasted to make the vehicle more beautiful, sturdy, and durable. This hydraulic lift folding ladder includes a frame, and the tail end of the frame is hinged with a ladder. The ladder is composed of upper and lower sections hinged together; The rear end of the frame is hinged with a hydraulic cylinder, and the end of the hydraulic cylinder piston rod is hinged in the middle of the lower section of the ladder. There is a support rod hinged between the rear end of the upper section of the ladder and the rear end of the frame; The front end of the upper ladder is equipped with rollers. The utility model has a simple structure, which improves the original climbing ladder into a two section hinged climbing ladder structure, increases the length of the climbing ladder, and lifts the climbing ladder through the extension and contraction of the hydraulic cylinder piston rod, which facilitates the lifting and lowering of the climbing ladder and has good practical value. The 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 height of the belly plate ranges from 400mm to 550mm, and the longitudinal beam is welded by automatic submerged arc welding. The frame is shot blasted and penetrated into the longitudinal beam and 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 trailers are typically used to transport heavy vehicles (such as tractors, buses, specialized vehicles, etc.), rail vehicles, mining machinery, forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.), and other heavy cargo. The stronger the ability to transport high cargo and pass overhead, the better. The structure and loading of low flatbed semi trailers usually adopt a concave beam (or well type) frame, with the front section of the frame being a goose neck (the traction pin of the goose neck front section 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 section being the cargo platform, and the rear end being the wheel frame (including the wheels).
