Europen Type Electric Double Girder Overhead Bridge Crane
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.
1.high reliability, safety, free maintenance rate;
a) work duty: FEM2M, M5
b) Protection class: IP55
c) Insulation class: F
d) continuing rate: 60% ( for the high class motor)
e) Cooling rate: 30% than normal crane
f) Over temperature protection: 170ºC
2.ompact design, small size, low dead weight, low headroom
4.Investment-saved---the workshop's civil work cost, due to crane's light dead weight and low wheel pressure.
5.ower-saved. The total motor power is much lower than normal design.
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.
1. Material use Q235B, or Q345B.
2. It is made of rectangular steel-pipe or steel plate by welding, the finished end carriage get 1-time positioning process on numeral control machine in order to ensure dimension accuracy and fit tolerance.
3. Each end carriage is supplied with wheels with double-wheel rim, buffer and anti-derailing protection device.
