Powerpack frame Sennebogen 6180 piling crane.
Hakkers owns a 180 ton crawler crane (Sennebogen 6180 HD) onboard of the working vessel ‘MS Noordzee’. This crane is utilised for amongst others heavy lifting up to 200 ton. Furthermore they can perform piling activities whereby the machine is extended with a leader mast and sliding table. In normal use, the powerpack of the vibrating block is positioned next to the crane what limits the slewing and traveling capacity.

Powerpackframe design
In order to increase the efficiency and to improve the safety of the operations, Vroegh-edc has developed a powerpack frame which is located on the aft of the ballast. The frame can be attached easily and together with the 15 ton weighing powerpack it ensures for a compensated ballast whereby the existing ballast is reduced. The total stability of the machine remained the same by this method.
Close consultation with the crane driver
Vroegh-edc has performed a concept design after measurements have been taken. In close consultation with amongst other the crane driver an optimised design was founded. After this, strength calculations have been performed as well as a detailed design including workshop drawings. Furthermore a stability analysis was performed to compare the original and new ballast configuration and to define the reduced ballast for an equal stability of the machine.
The machine including new powerpack frame is utilized on the Quarles quay in Flushing. Besides this assignment, Vroegh-edc also developed a lifting block specially designed for this project. See for more information: ‘Double lifting block SWL 60 ton‘.
