What is a Gantry Crane and What is it Used For?
A gantry crane is an overhead crane with one or two legs that move on wheels, tracks, or rail systems. Smaller gantry systems run on wheels or casters that can move throughout a facility for light fabrication work or maintenance. Larger gantry systems travel on rail or track embedded in the ground, typically running in a straight line or a work area. Gantry cranes are mainly used in the construction industry and have several applications. They are also used in power generating and manufacturing facilities, HVAC applications, shipyards, scrap yards, railyards, special steel mills, mining, and anywhere else where heavy loads are required to move.
