Matters should be hanging in the box girder cranes note
When using a crane hanging girder, be sure to follow the process, in order to successfully complete the box girder lifting work, Huazhong Construction Machinery installation based on years of experience, as we work to mention lifting few notes:
1 before the crane ready to lift, first check the various agencies, the appropriateness of the installation components, link is solid and so, only in the state to ensure that everything is safe, we can carry out lifting work.
2 in the process of decentralization spreader, spreader box girder connection point just, we use the rope flexible link, connect it between the spreader and the lifting point is a very convenient thing.
3 in the lifting of the process, we use to measure the level of detection of the lifting process just hanging box girder whether by force, torque each lifting point are equal, which once hung discontinuity points, the first discovery by crane hoist rope to adjust, if the adjustment is unsuccessful, we will immediately stop lifting work, good can only be adjusted again after lifting.
4 in the lifting of the process, in order to prevent the steel box girder in the process of lifting the swing is excessive, we generally use the chain hoist in its beams above to control it.
5 the crane outrigger deviation we set wind cable rope, in order to reinforce the lateral braking gantry.
6 lifting the work looks a hanging together, in fact, this work at all sloppy, our lifting steel box girder to the air, we must again carefully check whether there is loose among all the spreader and lifting points , slip hazards, check whether the crane track subsidence situation and so on.
7 from beginning to end, the operating speed of the crane we must control at 8m / min or so, cannot appear speeding.
8 box girder lifting just the process, in order to prevent wind, vibration force adversely affect their steel box girder swing, we have limited control over them, can not appear in any improper protected areas.
