Double girder gantry crane notice:
The workplace of the gantry crane is usually in the open air environment such as seaside wharf, next to the railway or other large factories of heavy industry, and the temperature in the open environment changes drastically. During the working process, factors such as vibration and shock are unfavorable to it. More seriously, when the capacity of the power supply transformer becomes smaller and the cross-section of the power supply cable is reduced, it often causes instantaneous voltage shortage.
Selection of gantry crane:
1. Double girder gantry crane Lifting capacity.
2. Span length.(rail center to rail center)
3. Lifting height.(hook center to ground)
