- Feb 02, 2018 -

Main girder Section

1, the main girder using square box-shaped ankang H-beam structure design, and the traditional first simple type of driving similar, heavy weight;

2, the main weld are nondestructive testing;

3, steel plate material for domestic general steel (Q235B);

4, vertical winding degree according to China's national standards;

5, with China's traditional cranes like all steel plate for shot peening pretreatment, to achieve Sa2.5 level standardization;

6, before welding carefully inspect and clean steel plate, usually by automatic welding machine line welding (MIG or semi-automatic welding);

End Beam Section

1. The end beam is rectangular steel pipe or steel plate welding molding, after forming the end beam in the numerical Control machine tool localization processing, achieves the allowable deviation scope, guarantees the national dimension precision and the match tolerance;

2. Each end beam is equipped with a wheel, bumper and anti derailment protection device with a double flange;

3, double girder crane in the direction of the main beam drive side layout maintenance platform (maintenance aisle);

4. The main beam and end beam are connected by high-strength bolts to ensure the precision and smooth running of the whole machine.
