INTRODUCTION

The shipbuilding gantry crane is a large-scale, heavy-lift gantry crane specifically designed for constructing ships and offshore structures. It features a double-girder bridge supported by two tall legs running on ground rails, with multiple trolleys and hooks for lifting and turning huge hull sections, engine blocks, and prefabricated modules. Lifting capacities typically range from 100t to 1,200t+, with spans over 100m and lift heights exceeding 60m. These cranes operate outdoors in coastal shipyards and are built to withstand harsh marine environments while providing precise, synchronized lifting for complex assembly tasks.

APPLICATION SCENARIO

[1] Hull Section Assembly – Lifting and mating prefabricated hull blocks in dry docks.

[2] Engine and Propeller Installation – Hoisting heavy marine engines, shafts, and propellers into position.

[3] Superstructure Fitting – Placing deckhouses, funnels, and masts onto the main hull.

[4] Block Turning – Using dual trolleys to rotate large hull sections for bottom welding.

[5] Launching Assistance – Cooperating with other cranes to slide a completed ship into water.

ADVANTAGES

[1] Ultra-High Capacity – Handles loads from 100t up to 1,200t+, essential for large vessels.

[2] Synchronized Lifting – Multi-trolley system allows precise control for lifting and turning heavy blocks.

[3] Long Span and High Lift – Wide span (>100m) covers entire dry dock; high lift height (>60m) accommodates tall ship sections.

[4] Marine Environment Durability – Corrosion-resistant coatings, sealed electricals, and anti-corrosion steel.

[5] High Duty Cycle – Designed for continuous, heavy-duty shipyard operations (A7-A8 duty class).

Six core advantages

Full Scenario Coverage

Nucleon covers over 20 product categories including ladle cranes, multi-purpose cranes, intelligent cranes, overhead/portal cranes, RTG, RMG, deck cranes, portal cranes, girder launchers, yacht cranes, KBK, and jib cranes. From steel smelting to port handling, bridge construction to ship equipment, Nucleon provides one-stop lifting solutions. Whether standard models or extreme-condition customizations, Nucleon possesses mature technical expertise and proven track records, saving customers from dealing with multiple suppliers.

Military-Grade Quality Standards

We use high-strength steel from Baosteel/Ansteel for key structural components, with 100% NDT inspection and one-clamp CNC gantry machining. Every machine undergoes 120% dynamic load and 125% static load tests before delivery, with continuous operation verification under extreme conditions. Even in 24/7 continuous casting plants, -40°C arctic ports, or high-temperature humid ship cabins, our cranes maintain millimeter-level precision and zero-drift stability—quality that stands the test of time.

Extended Longevity & Low Maintenance Cost

Our main girders are FEA-optimized and double-submerged arc welded, with a design life of ≥30 years. Key bearings are lifetime lubrication-free, and hardened travel wheels extend wear cycles by 3 times. Core components feature modular quick-change interfaces with spare parts commonality exceeding 80%. Annual maintenance costs are reduced by 40%~60%, saving millions in lifecycle operating expenses — truly "invest once, benefit long-term."

Energy Efficiency Leader

Our entire series comes standard with IE5 permanent magnet synchronous motors + energy feedback VFD drives, achieving 25%~35% comprehensive energy savings. Single-motor operation under light loads and adaptive speed control reduce electrical waste by over 30%. High-strength steel lightweight design cuts deadweight by 15%~20%, lowering workshop load requirements. A single ladle crane station saves over RMB 150,000 in electricity costs annually, helping customers achieve green and low-carbon production.

Ultimate Safety Redundancy Design

Our hoisting mechanism comes standard with dual brakes + mechanical overspeed switch + triple limit switches, featuring multiple redundant interlocks to prevent load dropping and over-traveling. Large products use box girder torsion-resistant structures, remaining stable even in level 8 gusty winds. Optional intelligent safety monitoring systems detect anomalies in load, skew, wind speed, etc., with automatic alarms and shutdowns. Overall safety redundancy coefficient > 2.0, maintaining zero crane safety incidents for many consecutive years.

Deep Customization & Full Lifecycle Service

We provide complete front-end support from site survey and mechanical simulation to civil review, delivering custom drawings within 2 weeks, with non-standard lead times only 5~7 days longer than standard products. We establish lifelong digital dossiers for customers, warning of end-of-life components 3 months in advance. Our full lifecycle services cover installation training, regular inspections, and remote O&M. With customer repeat purchase rates exceeding 85% for five consecutive years, we are a trustworthy long-term partner.
