Applications
Wallace Tri-Adjustable aluminum gantry cranes have a wide variety of indoor-outdoor, commercial and industrial applications where quick assembly and heavy lifting are required, when there is limited space, or when you need an economical way to lift and move heavy loads inside your facility and traditional cranes just don’t work. Our completely portable gantry cranes are often used in shipyards, scrap yards, construction, warehousing, manufacturing, and plant facilities, in repair shops, for HVAC applications, and more.
Below is a sampling of some of these applications.
