Abstract
A wind turbine blade and tower maintenance device, used for servicing, including cleaning, inspection, deicing and painting of wind turbine blades and tower. The device has: a plurality of balancing rods, a central hub, at least one tool arm adapted to releasably fix one or more tools adapted for surface maintenance; and a tool arm motor adapted to adjust the angle of the tool arm in respect a longitudinal axis of the central hub, wherein: the central rod and balancing rods are connected to the central hub; the tool arm is rotatably fixed to the central hub and the balancing rods and central hub are adapted to be connected to carrying and balancing ropes or cables. A system for lowering and raising of the arrangement is also disclosed.

1-10. (canceled)
Apparatus for wind turbine blade and tower maintenance comprising:
- a central hub;
- a plurality of balancing rods connected to the central hub, each one of the plurality of balancing rods extending radially outward and at an angle downward from the central hub and adapted to be coupled to a respective first end of a balancing rope or cable to stabilize the apparatus;
- a carrying rope or cable having a first end operatively coupled to the central hub, the carrying rope or cable configured to raise or lower the apparatus relative to a wind turbine blade;
- and
- at least one tool arm extending downward from the central hub and having a tool arm motor and a connector adapted to releasably fix a tool to the tool arm, the tool arm motor adapted to adjust an angle of the tool arm relative to a longitudinal axis of the central hub,
- wherein the tool is selected from amongst an inspection or testing head, a cleaning head, a high-pressure nozzle, a painting head, or a crack stitching head.
