Product Description

Product Description

ME shipbuilding gantry crane, a type of gantry crane of heavy lifting load, large span and high lifting altitude, is special for fragmented transport,end-to-end joint and turning operation of large ship hulls. Ship gantry crane task is to put all the parts required for the manufacture of the ship (ribs, steel, steel, etc.) from the ground transportation to manufacturing place. this transport work must be able to complete the task in a very long journey in transportation quickly. therefore, the number of cranes decided, enough to reach the dock area of the entire foundation, and each crane mutually interfere with each other in principle.

Application Scenarios

1. Heavy Industry & Manufacturing
Steel plants - Handling coils, plates, and structural steel.
Heavy machinery - Assembling and transporting large equipment (e.g., pressure vessels, wind turbine components).
Shipbuilding - Moving and turning ship hull sections.

2. Logistics & Warehousing
Ports & terminals - Container and bulk cargo handling.
Rail freight - Loading/unloading locomotives and railcars.
Large warehouses - Heavy-duty storage operations.

3. Energy & Infrastructure
Power plants - Installing/maintaining generators and turbines.
Bridge construction - Lifting prefabricated beams and steel girders.
Wind energy - Transporting turbine blades and towers.

4. Special Operations
Wide-span lifting - Ideal for workshops and open yards.
Dual-hook coordination - Efficient for long/oversized loads (e.g., pipes, trusses).
Precision control - Suitable for automated or high-accuracy tasks.

Our Advantages

1:Heavy Lifting Capacity
Dual winches provide higher load capacity (typically 5-500 tons) and better balance for heavy/oversized loads.

2:Precise & Stable Operation
Dual-girder design enhances structural rigidity, minimizing deflection during lifting.
Variable frequency control enables smooth acceleration/deceleration for millimeter-level precision.

Efficient Dual-Hook Coordination
Two winches work independently or synchronously, ideal for long/wide loads (e.g., pipes, ship sections).

Wide Coverage
Large span (10-50m) suits workshops, shipyards, and open yards.
Long travel distance along rails for continuous material flow.

Durability & Safety
Robust steel construction with anti-sway & overload protection.
Enclosed cabin offers safe, ergonomic control in harsh environments.

Low Maintenance
Modular design with easy-access components reduces downtime.

Packaging & Shipping

Bridge Crane packaging and shipping involves disassembling main/end beams exceeding 12m into match-marked sections protected by structural steel frames and VCI anti-corrosion coating, with critical I-beam flanges guarded by reinforced edge protectors; electric hoists and precision components are oil-immersed, foam-cradled in ISPM15-compliant wooden crates with silica gel desiccants (RH≤40%), while runway rails undergo zinc-plating and palletization; all cargo is secured using certified 5-ton lashing systems with shock-absorbing EPE foam (≥80mm) and rubber isolators (Shore A 60±5), complying with width/height limits (≤3.5m non-escorted; ≤4.8m vehicle height); mandatory documentation includes bilingual packing lists, lifting point schematics, HS Code 84261990, EN 10204 3.1 material certificates, and GPS/shock-logger transit reports; final on-site verification requires laser-alignment checks (≤3mm/m beam straightness) and 500MΩ insulation testing, with Institute Cargo Clauses A insurance covering transport risks.
