Abstract
A dolly-like device and associated operational procedure facilitate the transporting and setting of utility poles at locations inaccessible to motor vehicles. The dolly-like device includes a power winch that is utilized to provide the power to raise the pole in the pole setting operation.
Claims10
A device useful for transporting and setting a utility pole at a location inaccessible to a motor vehicle, said device comprising:
- a frame;
- a pair of wheels mounted at the bottom of said frame for (i) supplying rolling support for the frame and a utility pole loaded thereon in pole transporting operations and (ii) providing a horizontal axis of rotation for the frame during pole setting operations;
- front-to-rear spaced apart pole bearing surfaces located at the top of said frame for continuously engaging and supporting a utility pole thereon during both the pole transporting and the pole setting operations, said pole bearing surfaces defining a pole support plane that is inclined to match the inclination of the pole being raised during pole setting operations;
- a power winch with associated cable mounted on said frame at an elevation between said pole support plane and said wheels, said winch cable having a sufficient length so that during the pole setting operations the cable may engage to an anchor point opposite a hole into which the pole is to be set, thereby permitting the power winch to pull said device toward the hole;
- and
- said frame, wheels, pole bearing surfaces and winch being so positioned as to permit inclination of said pole support plane up to approximately 70 to 80 degrees during the pole setting operations while maintaining the pole bearing surfaces in pushing engagement with the pole and maintaining an unimpeded path for the winch cable from the winch to the opposite anchor point.
An operational procedure for transporting and setting a utility pole at a location inaccessible to a motor vehicle, said operational procedure comprising:
- loading a utility pole onto a pole support structure of a dolly-like device having a frame, wheels mounted to the bottom of the frame and a power winch and associated cable for supplying power to raise the pole at a pole setting location;
- transporting the pole to the inaccessible location by pushing the device and pole loaded thereon along the terrain encountered;
- digging a hole at the inaccessible location;
- as a first step in the pole setting operation, positioning the bottom end of the pole in the hole while rotating the frame of the dolly-like device about the rotational axis of the wheels to maintain the pole bearing structure in contact with the pole;
- securing the winch cable to an anchor point located on the opposite side of the hole from the dolly-like device and actuating the winch to pull the device toward the hole and the anchor point while continuing to rotate the frame of the dolly-like device to maintain continuous pushing engagement between the device pole bearing structure and the pole as the pole is raised;
- and
- raising the pole to an angle of approximately of 70 to 80 degrees from horizontal and permitting the pole to then fall into the hole and assume a vertical position.
A system for setting a utility pole in a hole comprising:
- (a) a hole in the ground for receiving a utility pole set therein;
- (b) an anchor point on the side of the hole opposite the side from which the pole enters the hole;
- (c) a cart device comprising:
- a frame;
- a pair of wheels mounted at the bottom of said frame for (i) supplying rolling support for the frame and a utility pole loaded thereon in pole transporting operations and (ii) providing a horizontal axis of rotation for the frame during pole setting operations;
- front-to-rear spaced apart pole bearing surfaces located at the top of said frame for continuously engaging and supporting a utility pole thereon during both the pole transporting and the pole setting operations, said pole bearing surfaces defining a pole support plane that is inclined to match the inclination of the pole being raised during the pole setting operations;
- a power winch with associated cable mounted on said frame at an elevation between said pole support plane and said wheels, said winch cable having a sufficient length so that during the pole setting operations the cable may engage to said anchor point, thereby permitting the power winch to pull said device toward said hole;
- and
- said frame, wheels, pole bearing surfaces and winch being so positioned as to permit the inclination of said pole support plane up to approximately 70 to 80 degrees during the pole setting operations while maintaining the pole bearing surfaces in pushing engagement with the pole and maintaining an unimpeded path for the winch cable from the winch to said opposite anchor point.
