1. Main beam adopts HG high strength steel, with high loading capacity, and
2. Main beaM adopts submerged arc welding technology, that ensure the smooth, sturdy welding seams and avoid welding-opening problems. And also improve the loading capacity.
3. Main beam height is 550-580mm. The front/down plate width is 220mm, and thickness is 22mm
That durable and stronger construction ensure the loading capacity, and also improve its capacity to twisting forces, shock, bump, and meet load requirements on bad road condition.
4. Side beam adopt “H” steel, height is 300mm, width is 140mm, and its thickness is 8/6/8mm. The durable design avoid the side beam to have the deformation.
