Turbine handling
02 October 2015
Four employees of Gerritsen On- & Offshore Services BV have handled routine turbine maintenance on an offshore location in the Southern North Sea, utilising an air operated hoist unit manufactured by J D Neuhaus for safe and effective lift and manoeuvre procedures for a turbine lift load of 12000kg.
The JDN Profi TI hoist was combined with an overhead rail mounted trolley, also air powered, to provide horizontal movements of the load. For maximum safety of operation in offshore conditions, a rack and pinion drive was incorporated into the trolley mechanism, with the whole lifting package also incorporating a spark resistant finish for operation within potentially explosive atmospheres.
Control operations for the hoist mechanism were incorporated into a JDN E-type pendant controller providing single speed control of the raise/lower/traverse load movements.
