Overhaul of 20.000 kg hook
De Haan Special Equipment B.V. finalized the complete overhaul of a Quadrex lifting hook for an offshore crane. For the re-use of the hook, a complete program should be fulfilled included all test and DNV approvals. The crosshead, shaft and threaded parts had to be re-machined and the bearing, hook-nut and seals are renewed. After a complete NDT test a special coating completed the hook for delivery. The complete unit has an own weight of approx. 20.000 kg
The delivery has been made at the end of 2015.
