In heavy equipment manufacturing, wind power, large-scale warehousing, and logistics, a double girder semi gantry crane can serve as a flexible material-handling hub in complex workshop environments. Its hybrid travelling structure combines a ground rail on one side with an elevated workshop runway on the other, helping facilities handle medium- and heavy-duty loads without the civil engineering cost of a full gantry crane.
Core Structure and Performance Advantages
The Henan Mine double girder semi gantry crane is structurally similar to an MG-type gantry crane. One supporting leg travels on a ground rail, while the leg-free end travels on an overhead runway attached to the workshop. This arrangement reduces the need for a second ground runway, makes better use of existing factory structures, and provides strong torsional resistance for frequent material handling.
The double-girder structure is suitable for medium- and heavy-duty workpieces and can be adapted to different lifting capacities, spans, lifting heights, working duties, and control requirements. For a broader overview of available configurations, see our heavy double girder semi-gantry crane guide.
Intelligent Safety and Energy-Efficient Operation
Supported by the Henan Mine technology research and development center, the hoisting mechanism uses a lightweight design and can support automatic high- and low-speed adjustment to reduce unnecessary energy consumption. The crane can be equipped with digital monitoring, video monitoring, and protection functions.
Optional intelligent systems include electronic anti-sway and automatic centering. Laser anti-collision and automatic deviation correction can also be configured according to the operating environment. Combined with reliable electrical components, including Schneider components, these functions help maintain stable operation in ambient temperatures from -20°C to +40°C.
Full-Life-Cycle Service
Henan Mine provides one-stop support from on-site surveying and drawing design to manufacturing, installation, and commissioning. A quality assurance system and more than 480 service outlets support domestic and overseas projects throughout the equipment life cycle.
How a Semi-Gantry Crane Reduces Civil Engineering Costs
Many industrial facilities face the same problem: a full gantry crane needs ground rails and foundations on both sides, while a conventional overhead crane may require expensive reinforcement of the workshop columns and steel structure. A double girder semi gantry crane offers a practical middle route.
One end runs directly on a ground track, while the other end uses an elevated runway supported by the existing workshop columns or crane beams. This configuration can avoid ground obstacles, reduce the load imposed on the building, and lower the amount of new civil construction required for a workshop lifting renovation.

FAQs
How can I get the most accurate price quote?
Cranes are non-standard customized equipment. The price depends on factors such as lifting capacity, span, lifting height, working duty, operating environment, and control method. Provide your workshop drawings and operating requirements so our engineers can prepare a free selection plan and an accurate factory quotation.
Can I install a double girder semi gantry crane if one side of my workshop is already built?
Yes. This is one of the main advantages of a semi-gantry crane. One leg can travel on a ground rail while the other end travels on an elevated runway connected to existing workshop columns or crane beams. The supporting structure must be checked by engineers before final design.
How does Henan Mine support overseas customers after delivery?
Henan Mine provides a 24-hour online response and full-life-cycle technical support. Optional intelligent functions, including laser anti-collision and automatic deviation correction, can also improve operating stability and reduce future maintenance requirements.
