For shipyards that need a rail-mounted gantry crane for ship block lifting, turning and final assembly, with project-specific single- or double-girder structure and rigid/flexible leg support.

Henan Mine Crane MU shipbuilding gantry crane source image associated with shipyard block lifting, turning and assembly operations.
The MU shipbuilding gantry crane is a bridge-type crane installed on dock or slipway rails. The source states that the crane uses a portal frame with either double main girders or a single main girder and is supported by a combination of rigid and flexible legs.
Its core shipbuilding duties are lifting hull sections, turning ship blocks and completing block assembly. For procurement, the crane should therefore be selected from the actual ship-block weight, dimensions, center of gravity, lifting points, turning method, assembly tolerances, rail gauge, lifting height and shipyard wind environment rather than from crane tonnage alone.

The source defines the MU crane as a special shipbuilding gantry installed on shipyard rails. Its portal frame can use a single- or double-main-girder structure and is supported by rigid and flexible legs to accommodate the large-span gantry arrangement.
Unlike a general yard gantry crane, the purchasing decision is driven by hull-section handling. The crane must cover the full block envelope during pickup, travel, turning and final fit-up. The shipyard should provide the largest block, heaviest block, lifting-lug positions, center of gravity and the exact turning / erection sequence before detailed design.
The source does not publish one universal capacity, span, lifting height, travel speed, turning synchronization tolerance, wind limit or positioning accuracy. These values should be engineered from the actual shipyard process and written into the technical agreement.
The source specifically identifies hull-section lifting, turning and assembly as the core operating tasks.
This source-confirmed arrangement is appropriate for a large rail-mounted portal frame and helps accommodate the shipyard gantry structure.
The source allows either structural form, so the final layout can be selected around load, span, stiffness, equipment arrangement and transport / erection constraints.
The complete crane uses PLC and inverter communication control according to the source, supporting smoother motion.
The source confirms a complete-crane safety monitoring system using operating-data and video-monitoring functions.
Primary load-bearing structures are analyzed by finite-element methods according to the source.
Buffers plus optimized hoisting and braking are source-listed to absorb impact and reduce vibration effects.

Source-confirmed product facts:
Buyer-defined items:
| Hull Block Lifting | Lift large prefabricated ship sections from fabrication / storage positions. |
| Ship Block Turning | Support the defined turning or flipping process before final assembly. |
| Block Assembly / Erection | Position ship sections for alignment and joining. |
| Dock / Slipway Handling | Rail-mounted coverage over shipbuilding production areas. |
| Shipyard Heavy Lifting | Project-specific handling of large shipbuilding structures and equipment. |
Provide the maximum block weight plus all lifting frames, spreaders and rigging.
Length, width and height determine hook coverage, turning clearance and portal dimensions.
This data is critical when the block uses multiple lifting points or a turning process.
Show the starting orientation, final orientation, hook / attachment arrangement and the clearance required throughout the turn.
Provide dock / slipway drawings with rail gauge, rail elevation, travel length and assembly positions.
State blocks per shift, annual production plan, operating hours and typical load spectrum.
If the lifting arrangement requires multiple hooks or coordinated motion, state measurable allowable differences and acceptance tests.
Provide design wind, operating wind, corrosion class or coating requirements and storm anchoring philosophy.
| Block Weight | Include the full suspended system, not only the steel block. |
| Block Dimensions | Largest length, width and height across all block families. |
| Center of Gravity | Required to calculate hook / lifting-point reactions. |
| Lifting-Point Coordinates | Provide lug or spreader connection positions. |
| Turning Method | Define the exact sequence and which lifting points change load during the turn. |
| Clearance Envelope | Check block swing against ground, rails, legs, other blocks and shipyard equipment. |
| Allowable Tilt / Height Difference | Project-specific if coordinated hooks or lifting points are used. |
| Acceptance Method | Define how turning, alignment and synchronized motion will be tested. |
| Source Position | The official source states that the portal structure can use either a single main girder or double main girders. |
| Double-Girder Consideration | May be selected when the project needs a structural / equipment arrangement that favors two main girders; final selection must come from engineering analysis. |
| Single-Girder Consideration | May be selected when the project load, span, stiffness and equipment arrangement can be satisfied by a single-main-girder structure. |
| Buyer Decision | Do not choose only by initial price. Compare block load, span, stiffness, trolley / hoist arrangement, access, erection and lifecycle maintenance. |
| PLC + Inverter Control | Source-confirmed complete-crane communication control for smoother motion. |
| Safety Monitoring System | Source-confirmed complete-crane system. |
| Data Monitoring | Signal transmission, acquisition, processing, storage and display are source-listed. |
| Video Monitoring | Source-confirmed as part of the safety monitoring system. |
| Finite-Element Design | Main load-bearing components use FEA according to the source. |
| Impact / Vibration Reduction | Buffers plus optimized hoisting and braking are source-listed. |
| Buyer-Specified Safety | Overload, limits, emergency stop, anti-collision, wind / storm protection and any synchronization monitoring should be defined in the technical agreement where required. |
Before manufacture, confirm the dock or slipway rail gauge, rail elevation, runway length, foundation reactions, erection space, crane assembly method, electrical supply, block-handling zones and all shipyard obstacles. The largest block-turning envelope should be checked against the final gantry geometry before production.
Maintenance should follow the final supplied crane manual and the shipyard's lifting procedures. Routine attention should cover hoisting mechanisms, ropes, hooks / lifting frames, brakes, wheels, gantry travel, rails, structural connections, buffers, PLC/VFD equipment, safety-monitoring sensors and video-monitoring equipment.
