Abstract
Systems and methods for installing a windmill are provided. The system has a hoisting platform and a carrier. The hoisting platform is operatively connectable to at least one platform leg extending a distance above a base. The hoisting platform is positionable along the platform leg(s). The carrier receives at least one component of the windmill, and is positionable about the hoisting platform and movable thereby whereby the component(s) of the windmill is/are positionable for installation.
Claims51
A system for installing a windmill, comprising:
- a hoisting platform receivingly engaging therein at least one platform leg extending a distance above a base, the hoisting platform slidably positionable along the at least one platform leg;
- a carrier to receive at least one component of the windmill, the carrier carried by the hoisting platform and movable thereby, the carrier slidably positionable along the hoisting platform whereby the at least one component of the windmill is positionable for installation;
- and
- a trolley carried by the carrier and slidably movable therealong, the trolley comprising a plunger extendable therefrom to selectively lift the at least one component.

A method for installing a windmill, comprising:
- providing a system to install the windmill, the system comprising:
- a hoisting platform receivingly engaging therein at least one platform leg extending a distance above a base, the hoisting platform slidably positionable along the at least one platform leg;
- a carrier to receive at least one component of the windmill, the carrier carried by the hoisting platform and movable thereby, the carrier slidably positionable along the hoisting platform whereby the at least one component of the windmill is positionable for installation;
- and
- a trolley carried by the carrier and slidably movable therealong, the trolley comprising a plunger extendable therefrom to selectively lift the at least one component
- transferring the at least one component of the windmill from the base to the carrier;
- transporting the at least one component of the windmill via the system to a desired position about the base;
- and
- operatively connecting the at least one component of the windmill to a foundation.
