How to Choose an Industrial Gantry Crane: Load Capacity, Span & Application Guide
An industrial gantry crane is a self-supporting overhead lifting system carried on freestanding legs rather than building-mounted runways, typically covering 0.5 to 800 tons of capacity and spans from about 6 to 50 meters depending on structure type. Because it doesn’t rely on the building structure to carry the load, it’s the default choice for outdoor yards, precast plants, shipyards, and any site where installing overhead runway rails isn’t practical. Most buyers start this decision by asking “what tonnage do I need?” — but tonnage is the third question, not the first. The two variables that actually determine whether a crane fits your operation are the application environment and the structural type, and getting those wrong is what turns a straightforward purchase into a re-engineering project six months later. This guide walks through a five-step selection framework — application, structure type, capacity/span/duty class, height and ground conditions, then certification — so you can walk into a supplier conversation with a complete specification instead of a single number.
