H-type Girder Assembly Tooling is suitable for assembly and welding of longitudinal beams and main cross beams, traction plates, suspensions and aileron plates of ordinary straight beam semi-trailers and ordinary gooseneck (within 300mm) semi-trailers; the tooling is equipped with longitudinal beam spacing positioning and longitudinal beam Front-end positioning device; pneumatic roller lifting and conveying device; one side of the longitudinal beam is the reference side, and the other side has a pneumatic clamping device for the longitudinal beam; the lower part is equipped with a pneumatic pressing device for the longitudinal beam, which is controlled by one valve and multiple cylinders; H-type girder assembly tooling other cylinders are controlled by one Cylinder one valve control; front-end gooseneck lifting mechanism pneumatic lifting + pad adjustment;
The H-type structure is stable and has strong load-bearing capacity, making it suitable for large-span bridges and buildings.
The manufacturing process of H-beams is mature and the cost is relatively low.
H-types have a long service life, good corrosion resistance, and relatively low maintenance costs.
Disadvantages:
The weight of H-type is relatively large, making installation and handling relatively difficult.
H-type may cause certain interference to existing traffic during the construction process.
HH-type require precise calculation and construction, making construction difficult.
