A forklift truck includes a linkage system for movement of a load carrier; and a base frame. The linkage system includes a moveable bearing contained within a channel; a first link arm pivotally connected to the moveable bearing; a second link arm pivotally connected substantially near a midpoint of the first link arm and at a fixed point substantially near a centerline of the channel; and a third link pivotally connected to the second link arm and to the connecting link at a pivot point at the opposite end. When the linkage system is moved between a retracted and extended position, a pivot point has a travel path that remains substantially perpendicular to the channel, and the angle through that pivot point and another pivot point remains substantially constant in relation to the channel.
