Abstract: A motorized extension ladder comprising a stationary first section, a moveable second section which is reversibly moveable from a proximate location to a distal location, a first cable pulley system with a first cable and first pulley to reversably move said moveable section from said proximate location to said distal location, and back, by a motor. The motor can be permanently affixed to the ladder, or operatively connected as required. A series of pulleys is provided which are moveable by rotation of a threaded rod, in order to cause the moveable section of the ladder to extend or retract. A motorized method for extending or retracting an extension ladder is provided.
