As professionals in the industry, United Renewables has set the bar with its unwavering commitment to quality, performance and exceptional customer care. Through our extensive industry knowledge, we go above and beyond to ensure your needs are not just met, but exceeded. United Renewables offers Craneless Large Component Replacements on Wind Turbines (Generators, Gearbox, Main-bearings, Blades, ext). The Self-Hoisting Crane eliminates the need for large mobile cranes when changing major components. The crane climbs from its container to the nacelle, suspended and guided by its own wires. Atop the turbine, the crane turns 180 degrees and installs on its base inside the nacelle, ready for operation.
