Welding process :
1) The main steel structure (main beam, end beam) materials are all Q235-B, the materials
used have material reports and corresponding certificates of conformity.
2) The manufacture, welding and inspection of steel structures are carried out in accordance
with national standards. The important force butt welds adopt double-sided groove
welding process, and visual inspection and non-destructive testing are carried out according
to regulations. All welders hold corresponding grade certificates.
3) All the main girder of the crane adopts the whole board without docking process, eliminating
the butt weld of the main beam steel plate, eliminating the hidden danger of the butt welding
of the steel plate. (Steel butt welding is the most important welding, and it is the most
dangerous part)
4) All the plates are automatically cut by CNC cutting machine, and the main beam crown is
preset to avoid the problem of the traditional fire-baked main beam arching.
5) The surface of the steel is shot blasted, and the surface roughness is hit to the Sa2.5 level
in GB8923 “Registration and Descaling Degree of Steel Surface Treatment before Painting”
to improve the adhesion of the paint and not to remove the paint to ensure the single
beam crane. Long-term beauty
6) The longitudinal girth weld of the main beam is ambushed by domestic advanced
automatic special plane, which is beautiful in appearance and ensures the welding quality.
7) The beam of the cart is made of rectangular tube. It has no splicing and no weld seams.
It has beautiful appearance and is durable.
8) The wheel installation is all boring, so that the wheel tread is not at the same level and the
wheel running accuracy is improved.
