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. The rotor can be secured to protect it against hurricanes or typhoons
for example.
Most components of the in board crane are stored under the hood of the nacelle. It takes about 8 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 in-board-hoisting-crane feature combined with the unique wind-diesel behavior of WES turbines make WES turbines the ideal fit islands.
