What’re the technical stand and documents of gantry crane?
1.1 MGHZ80/10-27-15 gantry crane drawings, layout of construction field.
1.2《GB50278-2010 Lifting equipment installation engineering code for construction and acceptance 》；
1.3 《QJ/GJ.026—D.006—01～006.02—93 Port machinery parts assembly, parts assembly, the general assembly general technical conditions and acceptance》；
2 when lifting the big parts which distance from the ground about 100mm, stop for 10 minutes to check the safety of every link, after making sure safety and then continue to lift. If the actual centre of gravity is different from the theoretical centre of gravity greatly, we should adjust the lifting steel ropes’length.
3 when welding the lifting eye, the main board of lifting eye and main girder reinforcement plate must keep alignment.
4 the tensile strength of steel is 1700Mpa
5 preparation work for installation: marking lifting steel rope, lifting mechanism, trolley, bend pulley block, electric hoist, handrail, ladder, platform , structure and electrical part etc.
