ABSTRACT:
A magnetically damped fork level indicating device comprises a housing having a gauge section; an elongate indicator arm pivotally coupled to the housing, the arm having first and second sections disposed on opposite sides of the axis; a weight coupled to the indicator arm so as to cause the first section to assume a predetermined orientation with respect to level ground; wherein the indicator arm at least partially overlies the gauge section and wherein the relative position of the indicator arm and the gauge section indicate the relative angular relationship between the orientation of the forks and level ground; a dampening means comprising a first magnet associated with the arm and moveable therewith and a second magnet associated with the housing and spaced from the first magnet, the second magnet magnetically coupled to the first magnet so as to dampen oscillations of the arm.
