MZ Grab Bucket Gantry Crane
For heavy bulk-material yards that need a double-girder grab gantry with repetitive cycles, automation functions and operator-access / camera monitoring.
Henan Mine Crane mz grab gantry crane showing the primary gantry structure and lifting arrangement.
The MZ grab gantry crane combines a double-main-girder gantry structure with a grab attachment for dedicated bulk-material loading and unloading. The source positions it for heavy repetitive bulk handling in demanding environments.
The source reports 3–5 seconds for a grab opening/closing action and also lists one-button automation, fingerprint authorization and a multi-camera image system. Buyers should define whether these automation and access-control functions are required as contractual scope.

Product Overview
Double-main-girder gantry combined with a grab attachment.
Dedicated to heavy bulk-material loading and unloading.
Grab opening/closing can use hydraulic or mechanical transmission.
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.

How to Select the Right MZ Grab Gantry Crane
1. Define the Bulk Material
Density, particle size, moisture and abrasiveness drive grab selection.
2. Define Throughput
Tonnes/hour and travel distances determine cycle requirements.
3. Define Grab Volume / Weight
Include grab self-weight in the suspended load.
4. Define Automation Boundary
State which movements are automatic and which remain manual.
5. Define Camera / Access Control
Specify required camera coverage and authorized-user procedure.

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.
