Types of Cranes Used in Shipyards

Shipyards play a vital role in the maritime and construction sectors, being integral to shipbuilding, repair, and maintenance. Cranes used in shipyards are essential for lifting and assembling heavy loads. In this article, we will explore the common types of cranes used in shipyards.

1. Tower Cranes

Tower cranes are among the most commonly used types of cranes in shipbuilding and maintenance. Their height allows them to lift heavy loads with ease, making them an essential tool in large shipyards. Tower cranes are often used in large-scale ship construction or repair projects.

Features of Tower Cranes

• High lifting capacity.
• Can work in large areas.
• Offers precise load handling.
• Easy to assemble and disassemble.

2. Portal Cranes

Portal cranes are mobile cranes that are typically used in larger shipyards. These cranes are especially useful during the production and assembly of large ships. With their high carrying capacity, portal cranes are ideal for moving ship components and speeding up the assembly process.

Features of Portal Cranes

• Mobile and can be used in large spaces.
• High carrying capacity.
• Ideal for shipbuilding.
• Durable and long-lasting.

3. Gantry Cranes

Gantry cranes are widely used for transporting heavy loads and are preferred for large construction projects, both in shipyards and beyond. These cranes typically operate between two horizontal tracks, allowing them to carry large loads in expansive areas.

Features of Gantry Cranes

• Operates on a dual-track system.
• Capable of carrying heavy loads.
• Provides mobility.
• Resistant to harsh weather conditions.

4. Wire Rope Cranes

Wire rope cranes are typically used in the early stages of shipbuilding and for transporting large metal components. These cranes are often designed for use in smaller spaces, providing secure and precise lifting capabilities.

Features of Wire Rope Cranes

• Typically used for short-range lifting.
• Limited lifting capacity but high precision.
• Quick and efficient in short spaces.
• Often used for smaller shipbuilding components.

5. Floating Cranes

Floating cranes are used on water, typically for large ship repairs and construction. These cranes are located on platforms that can move across water and are designed to handle extremely heavy loads, such as lifting or lowering ships into the water.

Features of Floating Cranes

• Operates on water.
• Capable of carrying extremely heavy loads.
• Used for launching or removing ships from the water.
• Resistant to water conditions.

Conclusion

Shipyards require various types of cranes designed specifically for shipbuilding and maintenance. Tower cranes, portal cranes, gantry cranes, wire rope cranes, and floating cranes play vital roles in heavy load lifting operations. Each crane type is designed to meet different lifting needs, contributing to the efficiency of the shipyard. The correct selection of cranes can have a significant impact on labor and cost efficiency in a shipyard.
