What Is a Shipyard Gantry Crane?
A shipyard gantry crane, also called a shipbuilding gantry crane or shipyard Goliath crane, is a large rail-mounted crane that spans a fabrication area, slipway or dry dock. Unlike a general yard crane, it is engineered to lift long and flexible hull blocks, coordinate several lifting points, turn sections in the air when required, and place modules at controlled assembly positions.
The crane structure commonly combines a double-girder bridge with one rigid leg and one flexible leg. This arrangement accommodates large spans while controlling structural restraint. The lifting system may use upper and lower trolleys, two coordinated trolleys or several hooks, depending on the block-turning method and required lifting capacity.
Hull Block Assembly
Lift decks, bulkheads, side shells and preassembled hull sections between fabrication, alignment and welding positions.
Dry Dock Erection
Position bow, stern, engine-room and superstructure modules during final hull erection and pre-launch construction.
Ship Repair and Conversion
Remove or install propulsion equipment, rudders, propellers, deck machinery and conversion modules during major dock work.
Offshore Module Handling
Handle selected vessel, platform, FPSO and offshore wind modules within a defined fabrication and assembly corridor.
Selection Considerations
01 / LOAD CASE
Block Mass and Load Distribution
Define maximum and typical block mass, dimensions, centre of gravity, lifting lugs, rigging mass and allowable local loads. Individual hook, trolley, combined and turning capacities must remain distinct.
02 / TURNING PLAN
Section Rotation Method
Establish pickup points, hook spacing, required rotation angle, load transfer between hooks, control sequence and permitted forces at every stage of the turn.
03 / GEOMETRY
Span, Lift and Hook Coverage
Map rail centres, dry-dock width, highest module, lowest hook position, side approaches, cantilever needs and all interference zones.
04 / DUTY
Operating Cycle and Design Life
State lifts and turns per shift, load spectrum, travel distances, operating hours, planned vessel program and future block-size changes.
05 / CIVIL WORK
Runways and Foundations
Coordinate wheel loads, wheel spacing, horizontal forces, storm anchoring, rail tolerances, drainage and geotechnical information with the civil design.
06 / COASTAL SITE
Wind and Corrosion Basis
Provide site wind data, storm procedures, temperature, salt exposure, humidity, rainfall and coating-life requirements.
07 / CONTROL
Power and Operating Philosophy
Define site supply, cable route, control stations, variable-speed motions, synchronized lifting, communications and data interfaces.
08 / DELIVERY
Transport and Erection Strategy
Confirm shipment segmentation, route limits, unloading method, erection cranes, temporary works, assembly space and site test responsibilities.
The lifting-capacity schedule must identify the permissible load for every operating case. The arithmetic sum of several hook or trolley ratings does not automatically establish the crane’s combined lifting or section-turning capacity.
Shipyard Gantry Cranes Compared with Other Gantry and Port Cranes
Crane type should follow the handled object and operating process. A shipyard Goliath crane is selected for large hull blocks and dock assembly; container and harbor cranes use different handling systems, motion requirements and acceptance criteria.
| Crane Configuration | Primary Load | Operating Area | Principal Selection Difference |
|---|---|---|---|
| Shipyard Gantry Crane | Hull blocks, superstructures and large marine modules | Shipyard fabrication area, slipway or dry dock | Very large span, coordinated hooks and engineered section-turning cases |
| Double-Girder Gantry Crane | Machinery, steel structures and general heavy cargo | Industrial yard or assembly bay | General hook handling without the complete ship-block turning system |
| Rail-Mounted Container Gantry Crane | ISO containers under a dedicated spreader | Container terminal or intermodal yard | Container stacking geometry, anti-sway and terminal operating cycle |
| Rubber-Tyred Gantry Crane | Containers or defined industrial loads | Paved yard with block-to-block mobility | Tyre travel and steering replace fixed shipyard rails |
| Container Straddle Carrier | Individual containers or compatible unit loads | Terminal transfer route | Mobile pickup and transport rather than full dock-span coverage |
| Portal Harbor Crane | Ship cargo, grabs, hooks or project cargo | Quay or terminal apron | Slewing and luffing cargo transfer instead of hull-block assembly |
Hull Block Lifting, Turning and Positioning
1. Establish Every Load Case
Engineering starts with the block in its fabrication position and follows it through pickup, initial suspension, rotation, load transfer, final orientation and landing. Hook forces can change substantially as the centre of gravity moves relative to the lifting points.
2. Select the Trolley and Hook Arrangement
Upper-and-lower trolleys can pass or work at different elevations. Two trolleys can distribute a long block across separated lifting points. Multi-hook systems require defined individual capacities, combined capacity, hook spacing and permitted simultaneous movements.
3. Control Motion and Synchronization
PLC supervision and variable-frequency drives can coordinate selected motions, limit speed during critical stages and monitor deviations. The allowable synchronization tolerance and response to a sensor, drive or communication fault must be stated in the technical agreement.
4. Verify the Lifting Attachment
Spreader beams, equalizing devices, slings, shackles and block lifting lugs form part of the load path. Their masses reduce available payload, and their geometry affects headroom, hook approach and section stability.
Shipyard Gantry Crane Specifications
The current Henan Mine Crane product data identifies the following available ranges. These values describe configurable equipment, not one automatic model combination. Final dimensions, speeds, duty, wind criteria, power supply, wheel loads and acceptance tolerances are established in the approved project documents.
| Parameter | Available Product Data | Project Definition |
|---|---|---|
| Lifting capacity | 100 t, 200 t, 250 t, 450 t or custom | Individual hook, trolley, combined-lifting and turning ratings |
| Span | 40–97 m in the principal family; separate listed configurations extend to 185 m | Rail centre distance, leg clearances, cantilevers and structural restraint |
| Lifting height | 35–70 m in the principal family; larger listed configurations use project-specific upper and lower hook travel | Highest and lowest hook positions including rigging and load depth |
| Working class | A7–A8 in the principal family; separate listed large configurations identify A5 | Selected from load spectrum, cycles, travel and required design basis |
| Hoisting speed | Main hoist 0.5–10 m/min; auxiliary hoist 1–20 m/min in the principal data | Full-load, no-load, positioning and turning-stage speeds |
| Travel speed | Trolley 5–30 m/min; crane long travel 10–40 m/min in the principal data | Loaded and unloaded speeds, acceleration, skew control and stopping distance |
| Operating temperature | −20°C to +40°C in the principal product data | Site minimum, maximum, humidity, salt exposure and solar heating |
| Power supply | 3-phase 380 V, 50 Hz; 400 V or 415 V available; listed very large configurations use 10 kV, 50 Hz | Site voltage, fault level, feeder, cable reel or conductor interface |
| Control modes | Cab, remote console and wireless remote operation | Permitted operating stations, authority transfer, emergency control and communications |
Separate listed configurations include two-trolley combined lifting capacities from 150 t to 1,000 t and section-turning capacities from 100 t to 800 t. These are independent engineered configurations and must not be treated as additions to the principal 100–450 t family.
Structure, Runways and Coastal-Site Design
Rigid and Flexible Leg Arrangement
A rigid leg transmits longitudinal and transverse forces while the flexible leg accommodates the deformation behavior of a very wide bridge. Girder geometry, leg stiffness, wheel groups and connections are evaluated as one structural system.
Runway and Foundation Interface
The crane proposal must provide wheel loads, wheel spacing, longitudinal and transverse actions, rail requirements and anchoring loads. Civil design must address soil conditions, differential settlement, rail alignment, drainage and access for inspection.
Wind Protection and Storm Parking
Anemometers, alarms, service brakes, rail clamps, storm anchors and tie-down provisions are selected around the governing wind basis. Current product data identifies 20 m/s operating and 55 m/s non-operating values for a specified configuration; contractual thresholds require confirmation against site wind data and the applicable design standard.
Marine Corrosion Protection
Surface preparation, coating system, dry-film thickness, edge treatment, enclosed-space protection, fastener materials and electrical enclosures must match the coastal exposure category and required coating life. Inspection access and touch-up procedures form part of lifecycle planning.
Control, Monitoring and Safety Functions
Coordinated Motion Control
PLC and variable-frequency control can coordinate selected hooks, trolleys and long-travel drives. The control narrative should define permissible simultaneous motions, speed limits and recovery from a failed device.
Load and Position Monitoring
Load values, hook positions, trolley positions, crane travel, wind speed and selected drive conditions can be displayed and recorded. Alarm and shutdown limits require defined acceptance tests.
Hoisting and Travel Protection
Overload protection, hoisting limits, travel limits, brakes, buffers, emergency stops, anti-collision and overspeed protection are specified for the selected mechanisms and applicable requirements.
Skew Control and Rail Protection
Long-span crane travel requires coordinated drives, rail-position monitoring where specified, wheel-flange protection and clear maintenance criteria for alignment and skew trends.
Current product data lists synchronization accuracy up to ≤3 mm for a specified coordinated-lifting configuration. The final tolerance, measuring method, load condition, permitted duration and response to deviation must be defined contractually before this value becomes an acceptance requirement.
Engineering, Manufacturing and Documentation
A shipbuilding crane purchase requires an agreed design basis and inspection plan before fabrication. Henan Mine Crane can establish the equipment scope around the shipyard layout, lift cases, local regulations and required project documents.
Design Deliverables
- Design criteria and load-case schedule
- General arrangement and hook-coverage drawings

- Inspection records and spare-parts schedule
Manufacturing capability and production facilities are presented in the Henan Mine Crane Factory Scene Display. The contract should identify which inspections are witnessed, which records are supplied and which criteria govern acceptance.
Delivery, Installation and Commissioning
Segmented Delivery Planning
Girder and leg segmentation must match road, port, vessel and site lifting limits. Packing, lifting points, temporary supports and storage conditions are agreed before dispatch.
Erection and Rail Verification
Site work includes rail survey, temporary stability, structural assembly, drive alignment, electrical installation and storm-restraint commissioning under the approved erection method.
Functional and Load Testing
Commissioning verifies individual mechanisms, coordinated movements, limits, brakes, alarms, emergency functions and applicable load cases. A section-turning demonstration requires an agreed test method.
Lifecycle Access and Spares
Platforms, access routes, isolation points and component-removal paths should be reviewed during design. Initial spares and long-term critical spares follow the operating and maintenance strategy.
Shipyard Gantry Crane Price and Project Cost
An early equipment budget of approximately US$200,000–US$1,000,000+ may be used for initial screening of new heavy shipbuilding gantry cranes. This range is not a fixed Henan Mine Crane selling price and does not represent an installed 450–1,000 t long-span Goliath system.
Large shipyard cranes are individually engineered. Very high capacity, dual-trolley lifting, section-turning systems, long spans, high lifting heights, high-voltage power and extensive coastal protection can move the project into a multi-million-dollar budget before foundations, rails, international transport, erection and commissioning are complete.
| Cost Package | Typical Inclusions | Principal Cost Drivers |
|---|---|---|
| Crane Equipment | Bridge, legs, wheel groups, trolleys, hoists, controls and specified safety functions | Capacity, span, height, duty, trolley layout, wind and corrosion requirements |
| Lifting and Turning System | Multiple hooks, spreader beams, equalizing equipment, sensors and coordinated controls | Block geometry, hook spacing, turning load cases and acceptance tolerance |
| Civil and Electrical Interfaces | Foundations, rails, storm anchors, drainage, substation, feeder and power distribution | Soil, wheel loads, runway length, voltage and site construction conditions |
| Delivery and Site Work | Packing, inland transport, ocean freight, unloading, erection, tests, training and handover | Shipment size, route, installation cranes, labor, schedule and test scope |
A valid quotation comparison uses the same capacity definitions, lift cases, span, height, working class, wind basis, coating system, control scope, power interface, documentation, delivery term and site-service boundary. Equipment-only pricing is not directly comparable with a complete installed-system proposal.
Shipyard Gantry Crane FAQ
What is the difference between a shipyard gantry crane and a general gantry crane?
A shipyard crane is designed around hull blocks, very large spans, coordinated lifting points and possible section turning. A general gantry crane normally performs single-hook or main-and-auxiliary-hook handling without the complete shipbuilding process package.
How much does a shipyard gantry crane cost?
An initial new-equipment screening range is approximately US$200,000–US$1,000,000+. Large 450–1,000 t long-span cranes with coordinated lifting and complete site works require individual engineering and can become multi-million-dollar projects.
Can one crane lift and turn a complete hull block?
Yes, where the crane, trolley arrangement, hooks, lifting attachments and control system are engineered for every stage of the turning operation. The turning capacity can be lower than the combined straight-lifting capacity.
Why are rigid and flexible legs used?
The rigid leg provides lateral restraint, while the flexible leg accommodates the deformation behavior of a very long bridge and reduces unwanted restraint. Final geometry follows the structural analysis and site layout.
What information is required for hull-block turning design?
Required data includes block mass, dimensions, centre of gravity, lifting-lug positions, allowable forces, rigging arrangement, initial and final orientations, turning sequence, landing supports and environmental limits.
Can the crane operate in coastal wind and salt spray?
It can be configured for the specified coastal environment. The design must state operating and storm wind criteria, parking procedure, clamps and anchors, coating system, enclosure ratings, materials and inspection intervals.
Are rails and foundations included in the crane price?
Only when expressly stated. The commercial schedule should separate crane equipment, rails, civil works, storm anchors, electrical infrastructure, transport, erection, commissioning and tests.
What power supply is required?
Power depends on crane size and site infrastructure. Current product data includes low-voltage three-phase supplies for selected models and 10 kV, 50 Hz for very large listed configurations. The final electrical design must match the destination grid and operating demand.
How is synchronized lifting accepted?
The technical agreement should state the measured variable, tolerance, load condition, travel distance, sampling method, alarm threshold and shutdown response. Factory and site tests then verify the agreed control performance.
What information is required for a formal quotation?
Provide maximum and typical loads, turning cases, block drawings, span, lifting height, runway length, dock cross-section, duty, wind and corrosion data, power supply, project location, required standards, inspection plan and delivery and installation scope.
