The Double-Girder Electric Hoist Semi-Gantry Crane is a versatile, high-capacity lifting solution manufactured by Henan Mine, designed for applications where full runway support is available on only one side of the work area. This hybrid crane configuration features one leg running on a conventional overhead gantry rail, while the opposite leg travels on a floor-mounted or low-elevation rail, combining the load-handling strength of double-girder construction with the space-saving adaptability of semi-gantry design .

The crane is equipped with an electric hoist (CD1/MD1 type or European-style hoist) as the lifting mechanism, with the hoist trolley running along rails on top of the two parallel box-section or truss main girders, providing exceptional stability and reduced deflection under heavy loads. Typical specifications include lifting capacity from 5 to 50 tons (standard, with special designs up to 500 tons), spans from 6 to 35 meters, lifting heights from 6 to 25 meters, working duty class A5 to A7, ambient temperature range from -20°C to +50°C, and optional features including variable frequency drive for smooth operation, anti-sway technology, wireless remote control, weatherproof covers for outdoor use, and full safety protection systems including overload protection, dual limit switches, and emergency stop .

Core Applications – Double-Girder Electric Hoist Semi-Gantry Crane
1.Steel Stockyards & Metal Service Centers – Handles heavy steel coils, plates, billets, structural beams, and pipe bundles in outdoor storage yards where a full gantry crane is not required and factory support structure is available on only one side .
2.Ports & Outdoor Terminals – Loads and unloads heavy containers, industrial equipment, and bulk cargo from trucks and rail cars in port back-up areas, with rail-mounted configuration enabling stable operation and optional cantilever extending reach beyond rail centers .
3.Precast Concrete & Construction Yards – Transports heavy precast concrete beams, bridge segments, pipe piles, and construction materials in open-air fabrication and storage yards, with strong wind resistance and optional weatherproofing for outdoor operation.
4.Machine Shops & Tool Rooms – Performs heavy material handling in workshops where only one side of the building has structural support for runway rails, allowing efficient use of limited floor space without interfering with existing EOT crane operations .
5.Power Plants & Heavy Industrial Facilities – Handles equipment installation, turbine maintenance, and heavy component lifting for large generators, transformers, and boilers in power generation plants requiring outdoor-capable heavy-lift cranes.
6.Mining & Quarry Operations – Moves extracted ore, heavy mining equipment, and large components in open-pit mines and processing yards where partial building support is available on one side for rail mounting .
