Disadvantages of this crane type are the higher power demand and increased maintenance requirement due to the increased number of moving parts. Knuckle boom crane arms are much lighter than boom truck cranes, and they are designed to allow for more payloads to be carried on the back of the truck that it is mounted on.
Lodbrok is a floating crane, in the harbor of Ystad 2020. A crane vessel, crane ship, crane barge, or floating crane is a ship with a crane specialized in lifting heavy loads, typically exceeding 1,500 t (1,476 long tons; 1,653 short tons) for modern ships.
