Autonomous Mechanical Wind Turbine Blade Polisher
Fully-mechanical, electricity‑free polishing system adaptable to any blade.
A self-sufficient mechanical polisher: portable gantry, rotary base, and Geneva-indexed gearing working together to ensure safe, consistent blade maintenance.
/ Challenge
Maintain and polish large blades in the field without electricity, while ensuring operator safety and consistent coverage.
/ Solution
A modular gantry and rotary base driven by a pneumatic circuit. Spur gears and a Geneva wheel index and sequence the polishing passes with repeatable dwell times.
/ Outcome
Electricity‑free operation, precise indexing, and safe handling of varied blade profiles with adjustable fixtures.
