WES30 In
Board Hoisting Crane
WES turbines can be equipped with an
in-board-hoisting-crane. The in-board-hoisting-crane makes it possible
to lower the rotor without an external crane. This is handy when a rotor
has to be lowered on short notice or when it is complex and takes too
long for a external crane to arrive.
Most components of the in board crane
are stored under the hood of the nacelle. It takes about 6 hours to
assemble the crane and to lower the rotor. The rotor is lowered with an
electrical winch, placed near the turbine. When the winch is not used it
can be stored in a shed, for example in the same shed where the control
cabinet is placed. Supports are placed at the base of the tower and
hold the rotor once it is on the ground. The rotor can be secured to
protect it against hurricanes or typhoons for example.
The
in-board-hoisting-crane feature combined with the unique wind-diesel behavior
of WES turbines make WES turbines the ideal fit islands.
