Gantry Crane 101: The Basics Of Gantry Cranes
In the world of material handling and heavy lifting, gantry cranes are indispensable workhorses. These robust and versatile material handling cranes are commonly found in various industries, ranging from shipping ports and construction sites to warehouses and manufacturing facilities. This guide will help you understand the basics of gantry cranes – their applications, how they work, different types, and their essential features.
Understanding Gantry Cranes
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.
