Product Introduction of Double-Girder Semi-Gantry Crane Manufactured by Henan Mine Machinery
Henan Mine Machinery's double-girder semi-gantry crane features a core asymmetric structure of “single/double-girder box-type main beam + single-side rigid support legs.” With a lifting capacity of 3-20 tons, customizable spans of 5-30 meters, lifting heights of 6-18 meters, and duty classes A3-A6, it operates reliably in complex environments including temperatures from -20°C to 40°C, high-dust conditions, and semi-open-air settings.
Core Features: Precisely tailored for heavy-duty requirements in small-to-medium confined spaces
- Flexible site adaptation: Utilizes a “single-end supported by factory crane beam track, single-end ground-mounted outrigger” design, eliminating the need for dual-side outriggers like full-gantry cranes, significantly saving lateral space
- Controlled foundation costs: Simple foundation work required only at the ground-supported end. Leveraging existing factory crane beams supports the other end, enabling “one crane covering both indoor and outdoor areas” and avoiding duplicate equipment purchases.
- Universal track compatibility: Factory-end tracks directly match existing bridge crane specifications. Ground-end tracks use standard light rail design for easy installation, drastically shortening site modification cycles.
