Abstract (en)
Altimeter for fork truck comprising a wire (5) with one end (6) fastened to the upper side of a fork carrier (4). The wire then extends upward and runs over a first pulley (7) in top of a first (top) mast section (1). From the first pulley the wire extends down to a second pulley (8) arranged in the bottom of the first mast section (1), under this upward and upward to a third pulley (9) in top of an intermediate mast section (2), over this and then down to a fourth pulley (10) in the bottom of the intermediate second mast section and further up to a fifth pulley (11) in top of a third mast (3) fastened in the truck. From the top of the third mast (3) the wire continues down to a sixth pulley (12) and from this up to the bottom of the fork carrier (4). The fifth pulley (11) is provided with a bearing of known type that measures the rotation thereof, for instance by a toothed disc, the teeth on rotation passing a led and a light sensor delivering a pulse for each tooth. The number of pulses can then be counted by an on board computer or by a separate display device calculating the fork height from the pulses.
