Gantry cranes are an ideal solution for applications where lifting is needed without the cost of a building or supporting steelwork. Similar to an overhead crane (or bridge crane),Website:http://www.dowellcranes.com, the runway is located on the floor rather than the ceiling for full gantry and semi gantry cranes. Portable gantry cranes use polyurethane wheels as it is used for light lifting.
Gantry cranes can be placed indoors or outdoors and cost less than an overhead crane system.
