Abstract
The present invention is directed to a ladder apparatus capable of being mounted to a vehicle. The ladder apparatus generally comprises a mounting support, a main ladder support for receiving an extension ladder, and a torsion support. The mounting support, the main ladder support and the torsion support are pivotally connected so that the apparatus can be raised from a retracted home position to an extended position. When the apparatus is in the extended position it can be set to a desired height and/or rotational position.
