Overhead Crane Types
The correct overhead crane configuration depends on more than lifting capacity. Girder arrangement, runway position, hoisting mechanism, load-handling attachment, working environment and production cycle all affect the final design. The following products cover general industrial lifting and specialized material-handling requirements.
Compare Overhead Crane Configurations
This comparison narrows the starting configuration. Final crane selection requires the actual load spectrum, runway data, building clearances and operating environment.
| Configuration | Main Selection Advantage | Typical Applications | Important Design Input |
|---|---|---|---|
| Single Girder | Lower structural weight and compact arrangement | Workshop, warehouse, assembly and maintenance | Headroom, building load and required hook approach |
| Double Girder | Greater rigidity and more room for hoist or trolley systems | Heavy manufacturing, wide bays and higher-duty handling | Load spectrum, span, wheel loads and duty class |
| Underhung | Preserves floor space and can follow suspended runway layouts | Hangars, large-span plants and space-restricted workshops | Roof capacity, support spacing and runway geometry |
| Explosion-Proof | Equipment configuration matched to a defined hazardous area | Chemical, oil and gas, coal-processing and combustible-dust areas | Gas/dust group, zone, temperature class and local standard |
| Metallurgical | Safety and thermal design for hot, high-duty material handling | Smelting, foundry, casting, rolling and billet handling | Material temperature, radiant heat, duty and emergency requirements |
| Grab | Purpose-built bulk material pickup and discharge | Coal, ore, aggregate, biomass, waste and stockpiles | Bulk density, grab volume, throughput and material characteristics |
| Electromagnetic | Reduces manual rigging for magnetic steel products | Steel mills, metal yards, plate shops and scrap handling | Load profile, steel temperature, magnet arrangement and backup power |
How to Select an Overhead Crane
An accurate overhead crane quotation starts with the operating requirement rather than tonnage alone. Provide the following information so the crane, runway reaction, hoisting system and safety configuration can be evaluated together.
1. Load DetailsMaximum load, normal load, load dimensions, center of gravity, attachment weight and whether synchronized lifting is required.
2. Working AreaRunway span, required lifting height, building clear height, hook approaches, obstructions and available maintenance space.
3. Operating CycleLifts per hour, operating hours per day, percentage of lifts near rated capacity and required hoisting/travel speeds.
4. EnvironmentIndoor or outdoor location, temperature, humidity, dust, corrosion, hazardous media, radiant heat and cleanliness requirements.
5. Control & PositioningPendant, radio remote, cabin or automated control; speed regulation, anti-sway, positioning and production-line interface requirements.
6. Site StandardsProject country, electrical supply, applicable crane standard, inspection requirements, documentation language and installation scope.
Popular Overhead Crane Capacities
Henan Mine Crane supplies customized overhead crane solutions across light, medium and heavy industrial lifting requirements. Frequently requested configurations include 1 ton, 2 ton, 3 ton, 5 ton, 10 ton, 20 ton, 30 ton, 50 ton and 100 ton overhead cranes. Capacity alone does not determine the correct crane type.
1–5 Ton Overhead CranesCommon for light manufacturing, maintenance, component assembly and warehouse handling.
5–20 Ton Overhead CranesUsed across general workshops, machinery production, molds, equipment maintenance and material transfer.
20–50 Ton Overhead CranesOften require closer evaluation of girder design, trolley arrangement, runway loads and duty class.
50 Ton+ Overhead CranesTypically engineered for heavy manufacturing, energy, metallurgy, large equipment assembly and project-specific lifting.
The examples above are selection starting points, not universal limits. Final capacity, span, duty and mechanism must be confirmed for the selected model.

What Determines Overhead Crane Price?
An overhead crane price cannot be determined reliably from tonnage alone. Two 10 ton overhead cranes can have different costs when span, lifting height, duty class, trolley arrangement, speed control, runway scope or environmental protection changes.
- Rated capacity, span and lifting height
- Single-girder or double-girder structure
- Electric hoist or open-winch trolley
- Working class, operating hours and required speeds
- Control method, automation and positioning requirements
- Explosion-proof, metallurgical, corrosion-resistant or other special design
- Runway, electrical supply, installation, commissioning and testing scope

Overhead Crane FAQ
Are overhead cranes, bridge cranes and EOT cranes the same?
The terms frequently describe the same general crane family: a bridge travels along elevated runways while a hoist or trolley moves across the bridge. “EOT crane” emphasizes electrically operated overhead travelling motion, while “bridge crane” and “overhead crane” are common market terms.
Should I choose a single-girder or double-girder overhead crane?
Single-girder cranes are often selected where a lighter and more compact structure meets the load and duty requirement. Double-girder cranes provide more structural and configuration flexibility for heavier loads, wider spans, improved hook approaches or demanding duty. Building loads and headroom must be checked before selection.
Can Henan Mine Crane supply a 5 ton or 10 ton overhead crane?
Yes. Five ton and ten ton capacities can be configured in several overhead crane structures. The suitable option depends on span, lifting height, duty, building clearance, load type and working environment—not capacity alone.
What information is required for an overhead crane quotation?
Provide maximum and normal load, span, lifting height, runway/building information, operating cycles, control preference, power supply, project country, environment and the material being handled. Drawings and site photographs improve proposal accuracy.
How is the required overhead crane duty class selected?
Duty class is determined by expected operating time, starts per hour, load spectrum, lifting cycles, travel distance and production criticality. Selecting duty class only from rated capacity can lead to an oversized crane or insufficient service life.
Which overhead crane control method should I choose?
Pendant control suits local operation; radio remote control gives the operator more freedom to choose a safe viewing position; cabin control is considered for long travel, high-duty or visibility-critical work. Automated and remote-station control may be integrated when the production process requires it.
Can an overhead crane be installed in an existing workshop?
It may be possible after checking the building structure, runway alignment, column and bracket capacity, headroom, clearances, electrical supply and installation access. Existing runway data should be reviewed before confirming crane wheel loads and geometry.
What affects overhead crane delivery and installation planning?
Engineering approval, component configuration, special protection, inspection requirements, transport dimensions, runway readiness, lifting access and commissioning scope all affect the schedule. These items should be agreed in the technical and commercial proposal.
