MHS Double-Main-Girder Electric Hoist Gantry Crane
For buyers needing more load-carrying stability than a single-girder electric-hoist gantry while retaining the lower complexity of an electric-hoist lifting mechanism.
Henan Mine Crane mhs double-main-girder gantry crane showing the primary gantry structure and electric-hoist lifting arrangement.
The MHS double-main-girder electric hoist gantry crane uses two main girders with an electric-hoist lifting system. The source positions it between a lighter single-girder hoist gantry and a more complex double-girder gantry using a wire-rope winch trolley.
The source states that a seated electric-hoist trolley can provide greater lifting height than a directly suspended hoist arrangement. Buyers should evaluate the value of this hook-height improvement against capacity, span and total gantry height.

Product Overview
Electric hoist is the lifting mechanism.
Double-main-girder gantry structure.
Source states higher load capacity and stability than a single-girder electric-hoist gantry.
Any capacity, span, speed, wheel load, energy saving, duty or other guaranteed value that is not explicitly published on the source page should be engineered from the actual project and written into the technical agreement rather than assumed from a similar crane.
Why Choose MHS Double-Main-Girder Gantry Crane?
Double-Girder Stability
Useful when the project needs a more stable bridge platform than a single-girder hoist gantry.
Improved Hook Height
The seated hoist trolley can increase usable lifting height.
Electric-Hoist Simplicity
Retains a simpler lifting mechanism than a full winch-trolley double-girder gantry.
Lower Maintenance Complexity
Source highlights simpler maintenance versus winch-type double-girder gantries.
Optional Cantilever
Can extend hook coverage beyond the clear span.

| Storage / Loading |
Rail-mounted handling with optional cantilever transfer. |
How to Select the Right MHS Double-Main-Girder Gantry Crane
1. Compare Single vs Double Girder
Choose MHS when stability, load, span or hook-height needs justify the second girder.
2. Compare Electric Hoist vs Winch Trolley
If very high duty or special performance is required, confirm whether electric hoist remains the right lifting mechanism.
3. Define Hook Height
Provide total crane height and highest required hook position.
4. Define Cantilever
Provide outside loading positions if needed.
5. Confirm Foundation Loads
Double-main-girder structure changes crane self-weight and wheel loads.
MHS vs Other Gantry Layouts
| Single-Girder Hoist Gantry |
Lower structural complexity where load / span requirements allow. |
| MHS Double-Girder Hoist Gantry |
More stability plus seated-hoist hook-height advantage. |
| Winch-Trolley Double-Girder Gantry |
Consider when duty or process performance exceeds practical electric-hoist requirements. |
| Buyer Decision |
Use real duty, hook height, span and lifecycle maintenance—not only initial price. |
Safety & Control: What Buyers Should Confirm
• Rated capacity, overload protection and below-the-hook attachment weight
• Upper / lower hoisting limits and gantry / trolley travel limits
• Brake and emergency-stop requirements
• Rail-end stops, buffers and anti-collision requirements
• Outdoor wind protection / anchoring or rail clamps where required
• Operator visibility and control method
• Attachment changeover interlocks where grab / electromagnetic equipment is used
• Factory and site load / functional acceptance tests
Installation & Maintenance
Before manufacture and installation, confirm rail center distance, runway length, rail elevation, foundation or building-runway capacity, available lifting height, cantilever clearance, power supply and erection access. Outdoor projects should also define wind, rain, dust and temperature conditions.
Maintenance should follow the supplied crane manual and actual duty. Routine work should cover the electric hoist, ropes, hooks / attachments, brakes, wheels, three-in-one drives where fitted, rail alignment, fasteners, limits and electrical protection. Semi-gantry cranes also require coordinated inspection of both the elevated runway and ground rail.

Frequently Asked Questions
How do I choose between a full gantry and a semi-gantry crane?
Use a full gantry when both sides should be ground-supported. A semi-gantry is relevant when one side can safely use an elevated building runway and the site benefits from a smaller floor footprint.
Should I add a cantilever?
Only when the hook must reach outside the clear span, such as a truck loading or storage position. Cantilever length changes structural reactions and should be defined from the site layout.
Are capacity and span fixed for these products?
Unless the source page explicitly publishes a value, capacity, span and lifting height should be engineered from the actual project.
What site information is most important?
A plan and cross-section showing rails, foundations or elevated runway, building / equipment clearances, loading positions and travel length will significantly improve quotation accuracy.
Can the crane be used outdoors?
Many gantry applications are outdoors, but wind, rain, temperature, corrosion and anchoring requirements must be specified for the actual site.
