VIDEO: Liebherr RL-K 7500 Subsea Crane Successfully Tested

The first LIEBHERR knuckle-boom-crane type “RL-K 7500 Subsea” has been tested successfully on Liebherr Rostock`s testbed on the 23rd of January 2013.

The RL-K 7500 with knuckle boom and AHC for underwater handling is able to lift 260 tonnes above the water surface and handle loads down to a depth of 3000 m.

As a heavy lift crane (without subsea functionality) lifting capacities of 300 tonnes are possible. Boom configurations are available for radii between 35 m to 50 m.

An advantage of the knuckle boom is that loads can be lowered to the water surface with a short rope length.
