Abstract

1284803 Bucket loaders CATERPILLAR TRACTOR CO 10 March 1970 [2 April 1969] 11402/70 Heading E1F [Also in Division H1] A tilt control system for a bucket loader having a vehicle with a pivoted lift arm 14 and a bucket 12 pivotally supported on the arm 14 with jacks 15 interconnected between the arm and vehicle includes a hydraulic jack 16, 17 for rotating the bucket 12 about its pivotal connection with the arm 14, a valve 27 in communication with tilt jack 16, 17 and including detent means 37, 41 tending to maintain the valve 27 in one of its operating positions R, D and releasable on operation of electrically responsive means 46 controlled by a proximity switch responsive to the tilt jack position and comprising a reed contact unit 51 biased by a permanent magnet 52 having its magnetic axis parallel to the contact reeds and controlled a movable permanent 53 having its magnetic axis perpendicular to that of the other magnet. For an ejector bucket the magnet 53 may also operate a second magnetically biased contact unit (not shown).
