A ship with a crane on board that specializes in lifting and carrying huge goods is referred to as a floating crane, also known as a crane ship or crane vessel. They are perfect for port operations or on rivers with little wharf facilities and are primarily employed for offshore construction.

Ports and bridges are frequently built with HL-Kattor Industry Co.LTD floating cranes. They are particularly handy while loading and unloading bulky cargo onto and off of ships. They are also used to move equipment on the sea deck, recover or place equipment on the seabed, and move equipment from one vessel or platform to another.
