Overview
Heavy Duty Gantry Crane
Our heavy duty gantry crane is designed to deliver strong lifting performance in both indoor and outdoor environments. Built for strength and adaptability, it handles oversized or heavy loads with smooth, precise motion. Whether used in shipyards, construction sites, logistics hubs or industrial yards, it keeps material moving with minimal downtime, and its rugged structure and modern control technology give safe, reliable and flexible operation in demanding conditions.
The range covers single girder gantry cranes of 1–20 t (span 5–30 m, lifting height 6–20 m, working duty A3–A5) and double girder gantry cranes of 5–100 t (span 10–50 m, lifting height 6–30 m, working duty A5–A6). Full figures are in the parameter table.
Key features
-
01
