MEH Double-Trolley Truss Gantry Crane
For wide outdoor work areas that need a truss gantry with two trolley positions and a segmented structure that can be transported through restricted site access.
Henan Mine Crane meh double-trolley truss gantry crane showing the primary gantry structure and lifting arrangement.
The MEH double-trolley truss gantry crane is a rail-mounted general gantry crane. The source lists working class A3–A5, optional cantilever arrangements and variable-frequency control for lifting and travel.
A key source feature is segmented construction: main girders and end structures can be transported through narrow areas and assembled by bolts on site. For a buyer, the double-trolley operating logic must be defined separately—maximum load per trolley, whether both are used together, lifting-point spacing and any synchronization requirement.

Product Overview
Product title identifies a double-trolley truss gantry crane.
Source working class A3–A5.
Optional cantilever on both sides, one side or no cantilever.
Any capacity, span, speed, synchronization accuracy, wind limit, temperature limit, throughput or other contractual value that is not explicitly published by the source should be engineered from the actual project and written into the technical agreement.
Why Choose MEH Double-Trolley Truss Gantry Crane?
Two-Trolley Process Flexibility
Two trolley positions can be engineered around separate or combined lifting tasks.
Transport-Friendly Segmentation
Useful where long crane structures cannot be delivered to site in one piece.
A3–A5 Source Duty
Provides a defined duty family for general outdoor operation.
VFD Motion
Supports smoother movement and positioning.
Flexible Span / Height
Source explicitly supports wide coverage and adjustable lifting-height design.

Two lifting points where the project requires them. |
| Equipment Installation |
Flexible lift height and trolley layout. |
How to Select the Right MEH Double-Trolley Truss Gantry Crane
1. Define Load Per Trolley
Provide each trolley's independent maximum load.
2. Define Combined-Lift Requirement
If both trolleys lift together, provide center of gravity and lifting-point spacing.
3. Define Synchronization
State any allowable hook-height difference; the source does not publish one universal value.
4. Confirm Transport Limits
Provide maximum module length / width / weight allowed to reach the site.
5. Confirm Outdoor Wind and Foundation
Truss geometry still requires project wind and rail / foundation data.
Double-Trolley Procurement Data
| Per-Trolley Load |
Do not assume equal load sharing. |
| Combined Lift |
Define whether both trolleys are ever used together. |
| Synchronization |
Project-specific; source does not publish a numerical tolerance. |
| Transport Modules |
Provide site access limits for segmented delivery. |
Safety & Control: What Buyers Should Confirm
• Rated capacity / overload protection and attachment weight
• Upper / lower hoisting limits and trolley / gantry travel limits
• Brake and emergency-stop requirements
• Rail-end stops, buffers, anti-collision and wind protection where applicable
• Attachment-specific safety: grab, magnet, metallurgical, gate, tipping or multi-trolley functions
• Operator visibility, remote-control or camera requirements
• Automation / linked-crane fallback and recovery procedures where applicable
• Factory and site load / functional acceptance tests
Installation & Maintenance
Before manufacture, confirm rail center distance, runway length, rail elevation, foundation or building-runway capacity, available lifting height, process clearances, power supply and erection access. Outdoor projects should include wind, rain, temperature, corrosion and anchoring conditions.
Maintenance should follow the final supplied crane manual and actual duty. In addition to hoisting, brakes, ropes, wheels, drives, rails, limits and electrical systems, inspect product-specific devices such as grabs, magnets, gantry hooks, gate equipment, tipping mechanisms, encoders, cameras or automation hardware.

Frequently Asked Questions
How is final crane capacity selected?
Use the complete suspended load, including the load plus grab, magnet, gantry hook, lifting beam, rigging or any other below-the-hook equipment.
Can span and lifting height be customized?
Yes. Unless the source publishes a range, these are project-specific and should be selected from the rail layout and working envelope.
What site drawing should I send?
Send a plan and cross-section showing rails, foundations or building runway, loading positions, obstacles, travel length and available clearances.
Can control or automation be customized?
Where the source supports VFD, PLC, linked operation, cameras, access control or other functions, the final scope should be defined from the buyer's process and acceptance requirements.
How should source-reported performance numbers be used?
Treat them as source product data. If a value is contract-critical for a new project, define the test conditions and acceptance method in the technical agreement.
