The New Type of Double-Girder Electric Hoist Semi-Gantry Crane is an advanced, high-capacity lifting solution manufactured by Henan Mine, engineered 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 an overhead gantry rail while the opposite leg travels on a floor-mounted rail, combining the load-handling strength of double-girder construction with the space-saving adaptability of semi-gantry design . The crane adopts lightweight, modular, and customized design principles, utilizing a new type electric hoist (NRT crab mode) as the hoisting mechanism, which offers superior performance, safety, reliability, energy savings, and environmental protection .

The double-girder box-type structure provides exceptional rigidity, reduced deflection under heavy loads, and excellent stability for both indoor and outdoor operations . Typical specifications include lifting capacity from 3.2 to 500 tons, spans from 3 to 60 meters, lifting heights from 6 to 25 meters, working duty class A5 to A7, ambient temperature range up to 50°C, and full variable frequency speed regulation for smooth, energy-efficient operation . Intelligent features include inching movement for precise positioning, dead slow function for stable loading, zero-speed hover to prevent slip hook, electronic anti-sway reducing load swing up to 95%, multi-hook coordination, multi-trolley synchronization, and wireless expansion for full lifecycle management via industrial internet platform .

It is widely used for intermittent cargo loading & handling in workshops, warehouses where one side is adjacent to factory building

Core Applications – New Type of Double-Girder Electric Hoist Semi-Gantry Crane
1.Tool Rooms & Machine Shops – Handles heavy tooling, dies, molds, and equipment in facilities where part utilization of the bay is required and full runway support is available on only one side .
2.Outdoor Steel Stockyards & Metal Service Centers – Transfers steel coils, plates, billets, structural beams, and pipe bundles in open-air storage yards where factory support structure exists on one side .
3.Ports & Terminal Back-Up Areas – Loads and unloads heavy containers, industrial equipment, and bulk cargo from trucks and rail cars in port facilities with asymmetrical building support .
4.Precast Concrete & Construction Yards – Moves heavy precast concrete beams, bridge segments, pipe piles, and construction materials in open-air fabrication yards requiring high-capacity outdoor cranes .
5.Heavy Manufacturing Workshops – Performs assembly and material handling for large machinery, ship sections, and industrial equipment in facilities where a full gantry crane cannot be accommodated .
6.Power Plants & Heavy Industrial Facilities – Handles equipment installation, turbine maintenance, and heavy component lifting for generators and transformers where partial building support is available for rail mounting .
