INTRODUCTION

Fixed offshore cranes (also known as quay cranes) are heavy‑duty pedestal‑mounted cranes installed on offshore platforms, docks, or quaysides for marine cargo and equipment handling. They feature a fixed tower or column, a hydraulic or electric luffing jib, and slewing capability up to 360°. Lifting capacities typically range from 10t to 200t, with working radii up to 50m. Built to withstand harsh marine environments (salt spray, high winds, wave motion), these cranes are essential for ship supply, drilling rig operations, and port container/bulk cargo transfer.

APPLICATION SCENARIO

[1] Offshore Platforms – Lifting drilling equipment, pipes, and supplies to/from supply vessels.

[2] Container Quays – Loading/unloading containers from ships to shore with high‑speed operation.

[3] Bulk Cargo Terminals – Handling coal, ore, grain, and cement using grabs or hooks.

[4] Shipyards – Assembling ship sections, moving heavy blocks, and launching vessels.

[5] Offshore Wind Farms – Installing turbine components and servicing foundations.

ADVANTAGES

[1] Marine Environment Certified – Corrosion‑resistant coatings, stainless steel fasteners, and sealed electrical enclosures.

[2] High Lifting Capacity – Up to 200t for heavy offshore and quayside lifts.

[3] Full Slewing Capability – 360° rotation for flexible load positioning.

[4] Smooth Luffing and Hoisting – Hydraulic or frequency‑controlled drives for precise control in rough seas.

[5] Low Maintenance – Modular design and offshore‑proven components reduce downtime.

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.
