Alatas Singapore - Overload Test of NMF Heavy Lift Crane
 

The vessel carries project cargo and is equipped with two Heavy Lift cranes, make NMF, type DKII 180012/7033, with a SWL of 180T at 12m each. The cranes also can operate as twin cranes for tandem crane lifts of up 360 ton. Alatas was tasked to carry out the crane overload test using waterbags and certified loadcell and issue a crane condition report, load test protocol and load test certificates.

Alatas, as the worldwide leading marine crane specialist offers additional services during load testing that typically are not available from other load test providers.
