Deck cranes include knuckle boom cranes, telescopic boom cranes, and stiff boom cranes. Knuckle boom cranes offer flexibility with articulated arms, while telescopic boom cranes provide adjustable reach. Stiff boom cranes are robust and ideal for heavy lifting operations.

Types of Deck Cranes: Hydraulic, Electric, Knuckle Boom, Telescopic, Stiff Boom.

Size: Ranges from 1-ton to 500-ton capacity, with boom lengths from 5m to 30m.

Grade: Typically complies with ISO 4301, FEM 1.001, or DNV/GL standards.

Viscosity: Hydraulic systems use ISO VG 32 to VG 68 hydraulic oil.

Buoyancy: Marine-grade cranes are designed for stability in water, with corrosion-resistant coatings.

Material: High-strength steel (ASTM A514, A572), aluminum alloys, and stainless steel components.

Rotation: 360-degree continuous or limited slewing, depending on design.

Power Source: Electric (400V-690V, 50/60Hz) or hydraulic (variable pressure systems).

Load Capacity: Varies by type, typically 1-ton to 500-ton SWL (Safe Working Load).

Corrosion Resistance: Marine-grade paint, galvanized, or stainless steel for saltwater use.

Control System: Manual, remote, or automated with PLC integration.
