What are the information of the crane installation?
The assembling and installing of the gantry crane should be done on a prepared foundation. Before starting the assembling and installing, you should read carefully the 
Operation Instructions of the MG Series Gantry Crane and the general layout drawings and electric diagrams, and check all the parts and their sizes.
(1) Rails for the gantry crane (rails for gantry)
i. The rails should be erected in a purpose to guarantee the safety operation of the gantry crane. This requires a solid soil foundation under the rails, providing the sufficient bearing capacity. There should not be any water accumulation softening the soil foundation. In case the gantry is used for long time with high load, it is recommended to make a concrete foundation and to pre-lay the bolts and cover and fix the steel plates on the concrete surface.
ii. The span of the rails shall be the same as that of the gantry crane. The maximum longitudinal slope is 1%. If higher than this value, the drive power of gantry and the stability of the whole machine should be inspected. In case the inspection results are not satisfied, the slope should be adjusted. The top surfaces of the rails of both sides should be in a same level. The connectors of the rails should be made smooth to enable a stable travel of the gantry. Travel spacing devices should be available on both ends of the rail.
