Cargo Handling Crane Types

A number of different types of cranes are found on merchant ships, each designed to handle specific cargo and operational requirements :

Manifold Cranes

    • Primarily used on tankers to handle hoses and pipes during loading and discharging operations.
    • Designed to withstand the harsh marine environment and the weight of heavy hoses.
    • Often hydraulically powered, offering precise control over hose movements.

Slewing Cranes

    • Highly versatile cranes capable of rotating 360 degrees.
    • Used for a wide range of cargo handling tasks, including general cargo, containers, and bulk materials.
    • Commonly found on multipurpose vessels and general cargo ships.
    • Can be hydraulically or electrically powered.

Deck Cranes

    • Smaller cranes mounted on the ship's deck.
    • Used for handling smaller loads, such as provisions, spare parts, and smaller pieces of cargo.
    • Often hydraulically powered and can be manually operated.
    • Essential for day-to-day operations on board the ship.

Bulk Cranes

    • Specialized cranes designed to handle bulk cargo, such as grains, coal, and ore.
    • Typically large and powerful, capable of lifting heavy loads at high speeds.
    • Often equipped with grabbers or clamshell buckets to efficiently load and unload bulk materials.
    • Common on bulk carriers.

Heavy Lift Cranes

    • Extremely powerful cranes capable of lifting heavy and oversized cargo.
    • Used for specialized tasks, such as transporting heavy machinery, construction equipment, and large project cargo.
    • Often installed on specialized heavy lift vessels or can be temporarily installed on other ships.
    • Require advanced engineering and precise operation.

Gantry Cranes

  • Large, overhead cranes that run on tracks along the quayside or on the ship's deck.
  • Primarily used in container terminals to efficiently load and unload containers onto and from ships.
  • Can be shore-based or ship-mounted.
  • Offer high lifting capacities and rapid transfer rates.

 

Portal Cranes

  • Similar to gantry cranes but with a single, rigid frame.
  • Often used in shipyards for lifting heavy components, such as engine blocks and propeller shafts.
  • Can also be used in container terminals, especially in smaller ports.

 

Mobile Harbor Cranes

  • Highly mobile cranes mounted on rubber tires or crawler tracks.
  • Used for a variety of tasks, including container handling, general cargo, and bulk cargo.
  • Offer flexibility and can be easily moved around the port area.

 

Floating Cranes

  • Large cranes mounted on barges or ships.
  • Used for heavy lift operations, such as installing offshore platforms and lifting large sections of ships.
  • Highly versatile and can be deployed in various water depths.
