What is Ship Cargo Handling Equipment?

Ship cargo handling equipment refers to all devices and machinery used for loading and unloading goods on vessels. The type of equipment depends on the cargo. Liquid cargo is moved using pumps, bulk cargo may use conveyors, cranes, or derricks, while packaged or large items are usually handled by cranes or derricks. Container ships often use dedicated port equipment.

Most general cargo ships are equipped with their own loading/unloading devices. This is because not all ports have enough equipment, and ships may need to transfer goods at sea or load supplies. On-board cranes help reduce port time, lower costs, and improve efficiency.

Types of Marine Cranes

Marine cranes can be divided into derrick cranes and slewing cranes. Based on power type, they can be steam, electric, or hydraulic. Today, most ships use electric or hydraulic cranes. Steam cranes are rare except on some tankers (for safety).




A good marine crane should:

• Lift rated loads at rated speed.

• Allow easy and flexible lifting/lowering.

• Hold and stop cargo safely at any time.

• Offer variable speed with smooth control.

• Be durable, efficient, and reliable.




It should also be simple to operate, easy to maintain, water-resistant, and use common spare parts.

How Deck Cranes Work

Deck cranes can be hydraulic or electric. Hydraulic systems are widely used because they:

• Transfer power over long distances easily.

• Allow full speed control with stable slow-speed operation.

• Provide high force/torque that stays constant over time.

• Are safe and reliable even in tough conditions. Safety valves prevent overload.




Many cranes use low-speed high-torque motors to drive the winch directly. This avoids the need for gearboxes. Some also use two-speed motors for light/heavy loads. Alternatively, high-speed motors with gearboxes are common in smaller cranes.

Variable displacement piston motors allow light loads to be lifted at higher speeds.




In hydraulic cranes:

• The hoist winch is driven by a hydraulic motor with constant torque in both directions.

• A mechanical brake is released by oil pressure during operation.

• The luffing winch adjusts the crane’s arm.

• A radial piston pump driven by an electric motor controls oil flow.

• The slewing system uses a hydraulic motor and pinion gear.

• Oil is cooled or warmed as needed.

• Temperature sensors and safety valves protect the system.

• All moving parts are lubricated by the hydraulic oil.




The crane structure is welded and mounted on a base. It contains mechanical, hydraulic, and electrical parts. Pulleys with ball bearings are used for lifting. Both luffing and slewing motions are controlled by one lever. Small movements release the brake, and further movement controls speed and direction. Safety devices include relief valves and overload protection.
