How Ship Deck Cranes Work

Crane Preparation and Positioning

• The crane is activated and positioned to the area where the cargo will be lifted, with the operator controlling the boom to ensure proper positioning.
• Stabilizing systems or outriggers may be activated to maintain the crane’s stability during operation.

Cargo Lashing

• The cargo to be lifted is prepared using ropes, chains, or other suitable fastening devices.
• Lifting devices such as hooks or spreader bars are connected to the cargo carefully to ensure safety.

Cargo Lifting

• The crane operator activates the winch to lift the cargo from the ship’s deck or dock, using a hydraulic or electric system.
• The cargo is lifted vertically to the required height, ensuring there are no obstructions or safety risks.

Cargo Transfer

• The cargo is transferred to the desired location, whether it is from the ship to the dock or vice versa.

Safety and Stability Considerations

Vertical Height Limits

• The vertical height limit of the crane is critical, as it affects the stability of the ship. The limit is measured to the tip of the crane boom, considering the ship’s heel and the suspended load’s swing[4].

Incline Angles

• Cranes on vessels must be designed to handle larger incline angles compared to land cranes. Computer simulations are used to ensure the ship never heels past the crane’s incline limit.

Structural Integrity

• The ship’s structure must be reinforced to handle the concentrated loads created by the crane. A naval architect analyzes the ship’s structure to ensure it can safely transfer the forces from the crane to the hull.
