Main girder structure1, main girder used European box beam mechanism design, light weight, reasonable structure;2, the whole plate production, no butt weld, compete by girder more solid.3, vertical deflection is 1/800, web camber by nc cutting plate blanking, high precision.4, the use of automatic submerged arc welding, NDT.After welding the whole blasting, eliminate stress, derusting, achieve Sa2.5 level 5, for Q235B steel material;Epoxy zinc-rich paint, the thickness of 120 microns,
Beam section1, beam for rectangular steel tube production,2, the beam in the form of boring, a positioning processing using CNC boring and milling machine, ensure dimensional accuracy and tolerance;3, each beam is equipped with a double flange wheels, buffer and anti cheat protection device, safety guarantee.4, main girder and end beam with magnitude 10.9 high strength bolt connection, make sure the whole machine structure strength and precision. 5, beam material: S355J2G3 / EN10025 (Fe52D, equivalent to the Chinese standard 16 mn);
Lifting mechanism1, the unique C type low headroom structure, effectively improve the lifting space up to 1 m.2, the motor + reducer + + brake limit switch four unity integration design, compact structure3, lateral hung flexible drive system4, all transmission mechanism adopts direct input and output model of no coupling, high transmission efficiency, high assembly accuracy and free of maintenance. Level 5 and level of work for the A5, IP55 protection grade, class H insulation.Dustproof, waterproof, improve safety level.
