Gantry crane erecting machine uphill bridge erection requirements

gantry crane Erecting Machine uphill bridge, bridge machine a good fight, according to the bridge slope adjustment in the front legs and leg height. Vertical shift before erecting machine, reducing the height of the front leg bridge machine, raise the height of the rear leg, so that the main stringer bridge machine slope <0.5%, and in the front of the hanging bridge hoist to prevent frame Traveling  bridge crane  in the process of decline. Guide beam walk the line in place, the front legs went cover beam, front legs in place, according to the leg height adjustment front leg height, leveling bridging machine, then erecting machine walk the line in place, then girder.

Erecting machine first cross beam erection Precautions
Erecting Machine first cross beam, usually in the legs of the bridge table, this time under the legs must be based on sliding tracks compacted to prevent bridging machine girder occurred during the sinking, causing the accident ; first leg vertical shift,bridge gantry crane you should adjust the leg height so that the front legs smooth place; erecting machine before the vertical shift, all the checks again, foolproof;
First cross beam erection, erecting machine has just started, everything not familiar with, not the pursuit of girder speed rather slow not fast, safety first.
