Lift-On/Lift-Off
Lift-On/Lift-Off (LO/LO) is a cargo handling method where containers are loaded onto and unloaded from vessels using cranes. This process is commonly used at ports and terminals equipped with ship-to-shore or mobile cranes. Containers are lifted vertically from the quay or vessel and carefully placed in designated positions. LO/LO is the standard handling method for container ships worldwide.
This method allows for precise and controlled movement of containers, making it suitable for both full and empty units. It supports efficient stacking in container yards and ensures proper placement on board vessels. LO/LO operations rely on trained crane operators and specialized lifting gear such as spreaders. This minimizes damage and maintains safety during handling.
LO/LO is especially effective in large container terminals where vessels carry thousands of containers. It enables fast turnaround times by allowing multiple cranes to operate simultaneously. The process also supports seamless transfer between vessels, trucks, and rail systems. This makes LO/LO essential for modern, high-volume port operations.
Overall, Lift-On/Lift-Off is a core component of containerized shipping. It ensures safe, efficient, and organized handling of containers at ports. By enabling reliable loading and unloading, LO/LO supports smooth vessel operations and global cargo movement.
Frequently Asked Questions about Lift-On/Lift-Off
Clear answers to the most common questions people have when learning about Lift-On/Lift-Off.
LO/LO is used at ports and terminals where cranes are available to lift containers directly onto or off vessels.
LO/LO uses cranes to lift containers, while RO/RO involves vehicles or cargo being driven on and off vessels.
It is mainly used for containerized cargo. Non-containerized or wheeled cargo usually requires different handling methods.
