Claims
- 1. An apparatus for pulling a cable comprising:
a) a boom assembly having a boom with a cable guiding device positioned thereon, said boom movable between a generally horizontal position and a generally vertical position; b) a movable base adapted to be mounted upon a vehicle so as to rotate relative to the vehicle about a vertical axis; c) a link mounted to the base at a first end so as to pivot relative to the base about an axis that is perpendicular to a longitudinal axis of the boom; d) a frame connected to a second end of the link that is opposite of the first end so as to pivot relative to the link about an axis that is perpendicular to the longitudinal axis of the boom; e) said boom assembly mounted to said frame so as to pivot relative to the frame about a horizontal axis that is parallel to the longitudinal axis of the boom; f) a cylinder attached between the base and a side of the boom assembly so that the boom assembly may be pivoted with respect to the frame; and g) a cylinder attached between the base and the boom assembly so that the link may be pivoted relative to the base and the boom assembly may be pivoted relative to the base and link.
- 2. The apparatus of claim 1 further comprising at least one swivel cylinder connected to said base and adapted to be connected to the vehicle so that when said swivel cylinder is activated, said base is rotated.
- 3. The apparatus of claim 2 further comprising a cam valve in communication with the swivel cylinder, said cam valve activating said swivel cylinder when actuated and said cam valve actuated when said base is rotated to a predetermined position.
- 4. The apparatus of claim 1 wherein said cylinder attached between the base and a side of the boom assembly includes aligned yaw and raise cylinders.
- 5. The apparatus of claim 1 wherein said boom is extensible along its longitudinal axis.
- 6. The apparatus of claim 1 wherein said frame is an A-frame.
- 7. The apparatus of claim 1 wherein in said link is a rectangular framework.
- 8. The apparatus of claim 1 wherein said boom assembly includes downward extending ears and a tube is mounted to said frame so that said boom assembly is pivotally mounted to said frame by a pin passing through the ears and tube.
- 9. The apparatus of claim 1 wherein said boom assembly includes a load beam that is pivotally mounted to said frame with the boom pivotally mounted to the load beam so that the boom pivots relative to the load beam about an axis that is perpendicular to the axis of the boom.
- 10. An apparatus for pulling a cable comprising:
a) a boom assembly having a boom with a cable guiding device positioned thereon, said boom movable between a generally horizontal position and a generally vertical position; b) a movable base adapted to be mounted upon a vehicle so as to rotate relative to the vehicle about a vertical axis; c) a link mounted to the base at a first end so as to pivot relative to the base about a first horizontal axis; d) a frame connected to a second end of the link that is opposite of the first end so as to pivot relative to the link about a second horizontal axis that is parallel to the first horizontal axis; e) said boom assembly mounted to said frame so as to pivot relative to the frame about a third horizontal axis that is perpendicular to the first and second horizontal axes; f) a cylinder attached between the base and a side of the boom assembly so that the boom assembly may be pivoted with respect to the frame; and g) a cylinder attached between the base and the boom assembly so that the link may be pivoted relative to the base and the boom assembly may be pivoted relative to the base and link.
- 11. The apparatus of claim 10 further comprising at least one swivel cylinder connected to said base and adapted to be connected to the vehicle so that when said swivel cylinder is activated, said base is rotated.
- 12. The apparatus of claim 11 further comprising a cam valve in communication with the swivel cylinder, said cam valve activating said swivel cylinder when actuated and said cam valve actuated when said base is rotated to a predetermined position.
- 13. The apparatus of claim 10 wherein said cylinder attached between the base and a side of the boom assembly includes aligned yaw and raise cylinders.
- 14. The apparatus of claim 10 wherein said boom is extensible along its longitudinal axis.
- 15. The apparatus of claim 10 wherein said frame is an A-frame.
- 16. The apparatus of claim 10 wherein in said link is a rectangular framework.
- 17. The apparatus of claim 10 wherein said boom assembly includes downward extending ears and a tube is mounted to said frame so that said boom assembly is pivotally mounted to said frame by a pin passing through the ears and tube.
- 18. The apparatus of claim 10 wherein said boom assembly includes a load beam that is pivotally mounted to said frame with the boom pivotally mounted to the load beam so that the boom pivots relative to the load beam about an axis that is perpendicular to the axis of the boom.
- 19. An apparatus for mounting a boom assembly to a vehicle comprising:
a) a movable base adapted to be mounted upon a vehicle so as to rotate relative to the vehicle about a vertical axis; b) a link mounted to the base at a first end so as to pivot relative to the base about a first horizontal axis; c) a frame connected to a second end of the link that is opposite of the first end so as to pivot relative to the link about a second horizontal axis that is parallel to the first horizontal axis; d) means for mounting the boom assembly to the frame so that the boom assembly pivots relative to the frame about a third horizontal axis that is perpendicular to the first and second horizontal axes; e) a cylinder attached between the base and adapted to be attached to a side of the boom assembly so that the boom assembly may be pivoted with respect to the frame; and f) a cylinder attached between the base and the frame so that the link may be pivoted relative to the base and the frame may be pivoted relative to the base and link.
- 20. The apparatus of claim 19 further comprising at least one swivel cylinder connected to said base and adapted to be connected to the vehicle so that when said swivel cylinder is activated, said base is rotated.
