Mg Double Girder Gantry Crane Move Loads Rapidly and Smoothly
Part 1 Descriptations:
MG Gantry cranes are all types of cranes which lift objects by an open winch which is fitted in a trolley and can move horizontally on a rail or pair of rails fitted under a beam. Gantry cranes are an excellent alternative to permanent indoor overhead cranes, which minimal investment in any new building by eliminating the need for increased foundational and structural considerations. In addition, they can be disassembled and moved to a new location easily.
We designed MG Gantry cranes with different capacities and spans that will meet your requirements.
Our designed Gantry Crane is with heavy loads up to 700t and spans can be over 50 meters. For fabrication and freight-transfer applications, it can move loads rapidly and smoothly.
Double Girder Gantry cranes are widely used for moving objects within shipyards, ports, rail yards, factories, and warehouses.
