Deck cranes are versatile lifting devices mounted on ships for loading and unloading cargo. They are designed to withstand harsh marine environments and ensure efficient operations. These cranes come in various types, including knuckle boom, telescopic, and stiff boom models.

Size: Typically ranges from 5 to 30 meters in boom length.

Grade: Commonly complies with ISO 4301, FEM 1.001, or DNV standards.

Viscosity: Hydraulic systems use oils with viscosity grades like ISO VG 32 or 46.

Buoyancy: Not applicable unless mounted on floating structures; stability depends on vessel design.

Material: Boom and structure made of high-strength steel (ASTM A572 or equivalent).

Load Capacity: Varies from 1 to 50 tons, depending on model.

Rotation: 360-degree continuous rotation with slewing bearings.

Power Source: Electric or hydraulic drive systems.

Operating Temperature: -20°C to +50°C (standard range).

Corrosion Resistance: Marine-grade coatings or stainless steel components.
