32 Ton Stone Field Use European Type Double Beam Electric Gantry
Crane
Product Description
32 Ton stone field use european type double beam electric gantry
crane is of foldable legs; easy assembly, easy installation,
labor-saving. It is of advanced technology, whose design is based
on international standard: FEM (Europe), DIN (Germany),
ISO(International), equipped with many advantages such as: strong
rigidity, light dead weight, low power, outstanding structure
design etc.
The configurations are very advanced, such as Schneider
electricals, ABM/Nord / SEW triple gear motor (three in one: motor,
gear box, brake), galvanized high strength wire rope, self-adjusted
disk brake, hard tooth reducer, programmable lifting limit switch,
and so on.
Girder Details
1. Main girder uses bias-rail box type structure, with optimized
design and light dead weight.
2. Steel material. Q235B, or, Q345B.
3. The cover and web plate should get surface rust removal by
roller-way conveyor blasting machine before welding; this blasting
machine can perform blanking, sandblasting, painting and drying,
after that they get to Sa2 level.
4. The welding work of main girder should be performed on work
platform (welding assembly unit). In order to avoid distortion of
main beam, we adopts U-shaped welding assembly unit to assure that
vertical deflection degree between the top cover plate and joint
edge of stiffened plate and web plate is no more than H/200, and
also effectively reduce the partial wave of web plate.
