Marine Deck Crane Supplier - Deck Cranes

Marine deck cranes are versatile lifting devices installed on ships for loading and unloading cargo. They are designed to withstand harsh marine environments and ensure operational efficiency. These cranes come in various types, including knuckle boom, telescopic, and stiff boom models.

Marine Deck Crane Specifications:

Size: Typically ranges from 1-ton to 100-ton lifting capacity, with boom lengths from 5m to 30m.

Grade: Constructed to meet ISO, DNV, ABS, or Lloyd’s Register standards.

Viscosity: Hydraulic systems use ISO VG 32 to VG 68 oils, depending on operating temperature.

Buoyancy: Designed to withstand marine conditions but not inherently buoyant; requires proper mounting.

Material: High-tensile steel (ASTM A514 or equivalent) for structural parts; stainless steel or galvanized components for corrosion resistance.

Deck Crane Specifications:

Size: Common capacities range from 0.5-ton to 50-ton, with boom lengths of 4m to 25m.

Grade: Complies with international maritime standards like IMO, SOLAS, or class society rules.

Viscosity: Hydraulic fluids typically ISO VG 46 for moderate climates, VG 68 for colder regions.

Buoyancy: Non-buoyant; relies on vessel stability and proper installation.

Material: Carbon steel (ASTM A36) or alloy steel (ASTM A572) with protective coatings (epoxy or zinc).
