Henan Mine Crane · Industrial Rail-Mounted Gantry Cranes
Overhead Gantry Crane
Lift and transfer materials across a workshop or outdoor yard with an industrial overhead gantry crane. A travelling hoist or trolley carries the load beneath the bridge, while supporting legs transfer the crane loads to ground-level rails and their foundations.
Henan Mine Crane manufactures single-girder, double-girder and semi-gantry configurations for production, storage and equipment handling. Select the arrangement around the load, hook coverage, ground conditions and operating cycle, with the crane and site interfaces defined in the quotation.

Which Overhead Gantry Crane Arrangement Fits Your Site?
The term overhead gantry crane is used for different lifting arrangements. The industrial models on this page are gantry cranes with an overhead lifting mechanism and rail travel. A full gantry has supporting legs on both sides; a semi-gantry has legs on one side and an elevated runway on the other.
An overhead bridge crane travels on two elevated runways, which may be supported by the building or an independent engineered structure. A small portable gantry on castors is another arrangement, with different floor, movement and load requirements.
Workshops without Elevated Runways
A full gantry can serve a working bay without relying on the roof structure for crane support. Ground rails, foundations and the moving-leg envelope still require space and engineering review.
Outdoor Storage and Fabrication
Serve defined pickup, storage and loading positions along a rail route. Include drainage, vehicle crossings, weather exposure and parking arrangements in the layout.
Long or Bulky Components
Check the complete path of beams, machinery and fabricated assemblies. Load orientation, leg clearance and any cantilever reach affect whether the crane can serve each position.
Overhead Gantry Crane Technical Specifications
The following reference ranges correspond to the linked Henan Mine Crane configurations. They describe different product arrangements, rather than a single standard machine.
| Configuration | Rated Capacity | Span | Lifting Height |
|---|---|---|---|
| Single-Girder Electric-Hoist Gantry Crane | 1–32 t | 6–35 m | 4–20 m |
| Double-Girder Electric-Hoist Gantry Crane | 3–50 t | 7.5–35 m | 4–30 m |
| Single-Girder Semi-Gantry Crane | 1–32 t | 6–35 m | 4–20 m |
These ranges do not establish every possible load, span and lifting-height combination. Confirm the selected combination, crane duty, mechanism duty, wheel loads and dimensions in the project proposal. The unit t denotes a metric tonne.
Other Specifications to Define
- Runway length, rail level, required hook approaches and any cantilever working area.
- Hoisting and travel speeds, positioning needs, lifts per hour and operating shifts.
- Site voltage, frequency, phases, incoming supply and crane power distribution.
- Pendant, radio remote or cabin control, with any process functions identified separately.
- Indoor or outdoor conditions, temperature, dust, corrosion and applicable design requirements.
Selection Considerations
01 / LOAD
Load and Attachment
Use the maximum payload together with slings, lifting beams or other suspended devices to establish the required capacity. Describe the load shape and centre of gravity as well as its mass.
02 / WORKING AREA
Clearance and Coverage
Mark pickup and placement points on a site plan. Check clear width between the legs, hook approaches, overhead obstructions and the swept path of long loads.
03 / GROUND INTERFACE
Rails and Foundations
Provide existing rail and foundation information where available. The proposed crane reactions and wheel arrangement are needed to assess support suitability and any required civil work.
04 / OPERATING CONDITIONS
Duty and Environment
Describe the handling cycle and exposure conditions. Hoist duty, travel duty, wind-related provisions and environmental protection must match the intended operation.
Overhead Gantry Crane Compared with Other Crane Configurations
Start with the support arrangement. A rail-mounted industrial gantry, a bridge crane and a portable workshop gantry place different demands on the site, even when the requested lifting capacity is the same.
| Configuration | Support Arrangement | Application Fit | Main Selection Check |
|---|---|---|---|
| Single-Girder Full Gantry | One bridge girder supported by legs on both sides. | Workshop and yard handling where the selected hoist and structure meet the duty. | Check leg clearance, hoist headroom and the complete ground-rail footprint. |
| Double-Girder Full Gantry | Two girders carrying the selected hoist trolley or lifting arrangement. | Projects needing a different trolley layout, lifting envelope or structural arrangement. | Compare wheel loads, hook height and mechanism duty; two girders alone do not define heavy-duty capability. |
| Semi-Gantry Crane | Legs and a ground runway on one side; an elevated runway on the other. | A work area beside a suitable elevated runway or supporting structure. | Both support systems require assessment, together with their alignment and the moving-leg route. |
| Overhead Bridge Crane | A travelling bridge on two elevated runways. | A bay with suitable elevated supports and a need to keep travelling legs out of the floor area. | Check runway support capacity, roof clearances and hook approaches. |
| Portable Workshop Gantry | A separate gantry arrangement commonly supported on castors. | Tasks where portability and local floor access are central requirements. | Select for the specified floor and movement conditions; load-travel permission is model-specific. |
Leg Clearance, Lifting Height and Cantilever Reach
The crane must reach the load and place it while keeping the load, hook block and lifting accessories clear of the structure. Check the working envelope on the general arrangement drawing, including the position of the moving legs.
| Layout Item | Practical Design Check |
|---|---|
| Span and clear leg width | Runway centreline spacing does not equal the unobstructed width between the legs. Leg shape and bracing can reduce the passage available for a load or vehicle. |
| Lifting height and rigging | Allow for the load dimensions and lifting accessories above the placement surface or obstruction. Overall crane height is different from usable hook height. |
| Cantilever and hook outreach | A girder extension beyond the legs can serve an outside loading position. Trolley end limits reduce usable outreach, and the permitted load at that position must be specified. |
| Runway length and end approach | The rail route must account for crane end limits, stops, parking space and the operating envelope. Full rail length is not the same as usable hook travel. |
For long material handling, an L-Type Offset Gantry Crane offers a different leg geometry to consider. A Truss Gantry Crane is another structural option; its joints, maintenance access and wind design still require evaluation.
Hoist, Travel Drives and Operating Duty
Hoisting and Cross Travel
The hoist lifts the load, while the travelling hoist or trolley moves it across the girder. Rope travel, hook configuration, braking and speed control must suit both lifting and placement.
Gantry Long Travel
The legs and bridge travel together along the ground rails. Wheel geometry, drives, frame alignment and rail condition affect tracking; a large gantry may need additional measures to manage skewing.
Controls and Attachments
Choose pendant, radio remote or cabin control around visibility and access. For grab-and-hook handling, confirm attachment mass, material properties and the required operating cycle.
A production crane used repeatedly near rated load needs a duty assessment based on load spectrum and operating cycles. Specify crane and mechanism classifications under the agreed standard; a capacity figure or a double-girder structure does not establish the required service duty.
Rails, Foundations and Power Supply
A ground-supported gantry still requires an engineered support system. Crane self-weight, lifted load, trolley position and operating conditions influence wheel loads and the reactions passed into the rails and foundations.
- Foundation and rail interface: establish the governing wheel loads, wheel spacing, rail section and connection details. Assess the ground, supporting structure and settlement conditions for the installation.
- Traffic and drainage: coordinate rails, cable routes, drains and vehicle crossings. Reserve clearance around moving legs and keep the agreed travel envelope available.
- Power distribution: evaluate cable reel, festoon or conductor arrangements against travel length, obstructions, weather exposure and electrical demand. Define the incoming supply boundary.
- Existing runways: check geometry, condition, level and support capacity against the proposed crane. Previous use by a crane of similar capacity does not establish compatibility.
Outdoor Protection and Safety Configuration
Outdoor use changes the design conditions. The crane specification must address the local environment and distinguish operating conditions from the parked, out-of-service condition.
Wind and Parking Provisions
Define the design wind conditions, operating limits, monitoring requirements and parking arrangements. Assess travel brakes, rail clamps and storm anchors as distinct functions with suitable load paths into the supporting structure.
Load and Motion Protection
Identify overload protection, hoisting and travel limits, emergency stops, braking and relevant electrical protections. Define control priority and the response to lost commands or interrupted power for the selected design.
Environment and Access
Specify rain, dust, temperature and corrosion exposure, including coastal conditions where relevant. Confirm enclosure protection, protective coating requirements and access for inspection and maintenance.
Wind limits and securing arrangements are specific to the engineered crane and site. Operating and parking procedures must follow the supplied instructions. Any hazardous-area or hot-material duty requires a separate specification review.

Overhead Gantry Crane FAQ
Is an overhead gantry crane the same as a bridge crane?
The terms are sometimes mixed in enquiries. A full gantry is supported by legs running at ground level, while a bridge crane runs on two elevated runways. Confirm the support arrangement on the layout drawing.
Does a self-supporting gantry crane still need foundations?
A full gantry carries its bridge through its own legs, but the resulting loads still pass into the rails and ground supports. Foundations or other suitable supporting structures must be assessed for the proposed crane.
Can a 5 ton or 10 ton gantry crane use a single girder?
These capacities fall within the reference range of the linked single-girder configuration. Suitability still depends on the selected span, lift, duty, hook coverage and site conditions; the exact combination requires confirmation.
Can the same gantry crane operate indoors and outdoors?
Only where its design covers the intended conditions. Outdoor use requires assessment of wind, weather exposure, corrosion, drainage and parking arrangements. Moving between indoor and outdoor areas also requires suitable clearances and travel infrastructure.
Can the crane lift its rated load on the cantilever?
The permitted load and working reach outside the legs must be stated for the selected design. Do not assume that every cantilever position has the same allowable load as the area within the span.
Can a gantry crane travel with a suspended load?
Powered rail-mounted gantries can be engineered for loaded travel within their specified operating limits. Permission and conditions for a portable gantry are model-specific. Follow the manufacturer’s instructions for the actual equipment and site.
How much does an overhead gantry crane cost, and when can it be delivered?
Request a quotation against the load, layout, duty and supply scope. Delivery should be confirmed against drawing approval, manufacture, inspection, transport and installation needs. A capacity-only enquiry cannot establish a reliable price or delivery date.
