The crane superstructure provides the structural support for the lifting mechanism, boom, operator cabin, and control systems on a floating crane. It transfers lifting forces to the hull and maintains stability during operations.
High-strength steel, such as grade S355 per EN 10025, is commonly used. The structure is protected with a corrosion protection coating system conforming to ISO 12944 C5-M for marine environments.
Rated lifting capacity ranges from 50 to 200 tonnes, maximum lifting height 30-80 meters, working radius 15-50 meters, hoisting speed 0.5-15 m/min, slewing speed 0.1-1.5 rpm, and operating temperature -20°C to +45°C. These are reference ranges; confirm with manufacturer.
Verification involves regular inspections for cracks, corrosion, and deformation, especially after heavy use or extreme weather. Design life is based on fatigue class per ISO 20332, typically 20-30 years. Always follow manufacturer guidelines.
