Boom Hinge Repair on 120T Deck Crane

Alatas Service

Equipment Type
120T Heavy Lift Deck Crane
CranesNMF, type DK II 120T


The vessel is equipped with two DKII 120016 / 55033 heavy lift cranes, each with a capability of 120 tons and a combined lift capacity of 240 tons. Crane 1 began to generate noise as it moved the boom. Our Engineer concluded that the boom foot has been damaged, and the bearing on the shaft has seized. A new boom hinge assembly must be purchased and installed.


As the NMF deck crane specialist, ALATAS sourced and supplied a new boom hinge piece complete with assembled bearing and heel pin. This was transported from Alatas Shanghai to the Australian ships. 
In collaboration with a local contractor, we then deployed our professional engineer to monitor the boom hinge pin and bearing repair, including function testing and proof load testing.
