Abstract
An improved fork lift truck having a scissor-actuated horizontal carriage motion system mounted on a horizontal frame. The carriage motion system providing for selectable positioning in a compact space of a lift assembly between a position forward of and behind the front wheels. The lift assembly provides downward pressure and is vertically moveable from and to a position which is below ground level and a further position above the level of the fork lift truck. The fork lift truck also provides a pair of outriggers which discontinue movement and remain stationary if they contact an obstruction, while the other outriggers continue to extend, the outriggers being moveable both horizontally and vertically relative to the remainder of the lift truck.
