Application No. 09/347,695
Main support frame 16 has a transverse supporting beam 42 which includes an
integral collar 44 as shown particularly in Figures 2 and 3. Brackets 46 secured to
longitudinally extending arms 22 mount beam 42 for relative limited pivotal movement
with vibratory frame 18 about pivots 48. A lower support plate 50 is secured to cross
beam 42 and has a central opening 52 therein. Cross beam 42 has a pair of upwardly
extending extensions 54 thereon. A pair of parallel hydraulic cylinders 56 are pivotally
connected at 58 to extensions 54 and have upwardly extending piston rods 60. An
upper cross beam 62 is pivotally connected at 64 to the upper ends of piston rods 60
and has an integral collar 66 centrally of its length. Received within collar 66 is a push
member or tube generally indicated at 68. A pair of opposed chains 70 extend between
cross beam 62 and push tube 68 for raising and lowering push tube 68.
A pair of sleeves 72 are fixed to cylinders 56. A U-shaped arm 76 as shown
particularly in Figure 5 extends between and is secured to sleeves 72. Cylinder 36 is
pivotally connected at 40 to arm 76 and to the rear of tractor 14 at pivot 38 (see Figures
1 and 4). Lower cross beam 42, collar 44, plate 50, cylinders 56, upper cross beam 62,
and U-shaped arm 76 define an intermediate frame between support arms 22 of main
frame 16 and vibratory frame 18 supported on pivots 48 of main support arms 22 for
limited relative pivotal movement. This intermediate frame supports vibratory frame 18
and moves with vibratory frame 18 during tilting relative to main support arms 22 upon
