NMF Boom Hinge Repair

Alatas Service: Field Service
Location: Singapore
Manufacturer: NMF
Model: DKII

For this NMF boom hinge repair project, a DKII Heavy Lift Crane had suffered from excessive bearing wear.

The bearing bushes had disintegrated and both boom hinge piece and boom hinge axle shaft were worn. Alatas Singapore mobilised it’s specialist Field Service Crane Repair team to carry out afloat repairs.

Our experts dressed up the damaged areas on the boom hinge bore and bolt and by manufacturing and installing oversized bearing bushes with additional grease grooves.

The job was carried out at anchorage without removing the crane boom. Instead, it was it temporarily suspended via chain blocks affixed to the crane slewing column via pad-eyes.

The job was carried out within four days, working 24 hours around the clock.
