Dreggen said the DKF1250 cranes will be able to lift 100t at depths up to 3,000m. It is based on its established knuckleboom crane design but will be equipped with Bosch Rexroth’s secondary controlled winch drives. This drive manages and compensates the primary load and additional wave motions and oscillations.
