Service Without a Crane

The Tilt-Down Advantage

Conventional turbines need cranes and tower climbs for every inspection. The Carter tilt-down tower changes the economics of ownership entirely.

01

Release & Winch

The hinged tower base is released and a ground-level winch takes the load, lowering the tower under controlled tension.

Service at Ground Level

Nacelle, generator, and rotor arrive safely at the ground where technicians work without climbing or lifting equipment.

Raise & Run

Once work is complete, the winch raises the tower back to vertical and the turbine returns to production — often in a single visit.
