The Double Girder Tyre Gantry Crane, also known as Double Girder RTG, is a heavy-duty gantry lifting solution equipped with rubber tires for mobility without the need for fixed ground rails. Featuring a double-box girder structure, it offers superior load-bearing capacity and enhanced overall rigidity compared to single girder models, making it ideal for ports, rail freight stations, logistics hubs, and industrial facilities. The crane delivers exceptional maneuverability and site adaptability, supporting multiple travel modes including straight, oblique, crab steering, and 90° to 360° on-the-spot rotation for flexible movement on level ground. Lifting capacities range from 10 to 200 tons, with lifting heights of 6 to 15 meters, spans of 10 to 20 meters, and work duty classes of A6 to A7, accommodating medium to heavy operational demands. The crane is certified to CCS, CE, ABS, and BV international standards.
