The invention involves a wind power plant for converting wind power into electric energy and a process for replacing machine parts of the housing of a wind power plant of this type using on-board mechanisms. According to the invention, the wind power plant has a tower, a housing that is mounted onto the tower and functions to receive machine parts that include at least one gear and one generator, whereby the housing also has a longitudinal axis oriented essentially crosswise to the tower axis, and, on the underside of a housing part that is set off at a distance from the tower in the direction of the longitudinal axis, has an opening that serves the purpose of allowing machine parts to be moved through it, and the wind power plant also has an on-board crane arranged in the housing in order to convey objects in the direction of the tower axis. Furthermore, the wind power plant has a container functioning to receive structural parts, whereby the container can be moved underneath the opening in the direction of the longitudinal axis from an operating position, in which an area of the opening near the tower is covered by the container, into a mounting position, in which this area of the opening is unblocked.

The wind power plant according to claim 1, wherein the area of the opening near the tower serves the purpose of allowing the gear or parts of the gear to be moved through it using a crane.3. The wind power plant according to one of the preceding claims, wherein, in the operating position of the container, an area that is located beneath the generator of the opening is unblocked. 4. The wind power plant according to one of the preceding claims, wherein the gear is arranged near the operating position of the container and is coupled to the generator by a drive connection that extends in the direction of the longitudinal axis. 5. The wind power plant according to one of the preceding claims, wherein objects are conveyed using the on-board crane in the direction of the longitudinal axis of the housing. 6. The wind power plant according to one of the preceding claims, wherein the container is suspended on the housing part using running wheels that are guided on rails. 7. The wind power plant according to one of the preceding claims, wherein the container functions for receiving electric components and power cables are provided extending between the container and the generator and the container and the tower, which are foldable into a loop to shorten their length when the container is moved between the operating position and the mounting position, and they can be extended to expand their length out of the looped form. 8. The wind power plant according to one of the preceding claims, wherein the operating position of the container is adjustable in a continuous manner in the direction of the longitudinal axis of the housing. 9. A process for mounting of a machine part of a wind power plant, in particular, a gear or gear part, in a housing that is mounted on a tower, which has a longitudinal axis that is oriented essentially transversally to the tower axis, an opening that is arranged on the underside of a housing part that is set off at a distance from the tower in the direction of the longitudinal axis, whereby the opening serves the purpose of allowing machine parts to be moved through it, and an on-board crane arranged in the housing for conveying objects, the process comprising moving a container functioning to receive the structural component beneath the opening in the direction of the longitudinal axis of the housing from an operating position, in which an area of the opening near the tower is covered by the container, into a mounting position at a larger distance from the tower, in which this area of the opening is unblocked, the on-board crane pulling the machine part along the tower and through the area of the opening near the tower, the on-board crane transporting the machine part in the direction of the longitudinal axis of the housing to a planned mounting position of the machine part, and moving the container from the mounting position back again into the operating position. 10. A process for dismounting a machine part of a wind power plant, in particular, a gear or gear part, in a housing that is mounted on a tower, which has a longitudinal axis that is oriented essentially transversally to the tower axis, an opening that is arranged on the underside of a housing part that is set off at a distance from the tower in the direction of the longitudinal axis, the opening serving the purpose of allowing machine parts to be moved through it, and an on-board crane arranged in the housing for conveying objects, the process comprising moving a container functioning to receive the structural components beneath the opening in the direction of the longitudinal axis of the housing from an operating position in which an area of the opening near the tower is covered by the container, into a mounting position at a larger distance from the tower, in which this area of the opening is unblocked, the on-board crane transporting the machine part in the direction of the longitudinal axis of the housing to a position above the area of the opening near the tower, the on-board crane letting the machine part down along the tower through the area of the opening near the tower, and moving the container from the mounting position back again into the operating position.
