ME New-Type Double-Trolley Gantry Crane
For modern yards that need two trolley systems with independent or joint operation, efficient integrated drives and operator positioning guidance.
Henan Mine Crane me new-type double-trolley gantry crane showing the primary gantry structure and lifting arrangement.
The ME new-type double-trolley gantry crane is a general rail-mounted gantry crane with two trolleys. The source lists working class A3–A8 and states that the two trolleys can be used independently or in combined operation.
The source confirms encoder and CI-card inverter technology for double-trolley control, three-in-one direct drives for trolley and gantry travel, and an optional crane projection light to warn operators or guide load positioning.

Product Overview
Source working class A3–A8.
Trolley and gantry travel mechanisms use three-in-one direct drives.
Double-trolley control uses encoder and CI-card inverter technology.
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 ME New-Type Double-Trolley Gantry Crane?
Independent or Joint Trolley Use
Source explicitly supports separate and combined operation.
Encoder / Inverter Coordination
Supports more structured two-trolley control.
Three-in-One Drives
Integrated travel drives reduce transmission interfaces.
Projection Guidance
Can help operators align the load or define a warning area.
A3–A8 Source Duty
Broad duty range supports project-specific selection.

How to Select the Right ME New-Type Double-Trolley Gantry Crane
1. Define Total and Per-Trolley Load
Center of gravity may create unequal trolley loads.
2. Define Lifting-Point Spacing
Required for long or large loads.
3. Define Synchronization
State allowable height difference / tilt for joint operation.
4. Define Projection-Light Use
Specify warning or positioning purpose and required reference location.
5. Select Duty A3–A8
Use real cycles / load spectrum.

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.
