Pole-setting apparatus

A pole-setting apparatus comprising, a boom assembly connectable at one end to a ground-engaging dolly, a cradle support structure having a pair of spaced-apart side plates and interconnecting members and rotatably mounting a pair of tires, means defining a first connection of said side plates to another end of said boom assembly, a cradle assembly including a cradle frame pivotally mounted intermediate its ends to said side plates at a distance from said first connection, a hydraulic cylinder positioned between said side plates and pivotally connected at one end to said side plates at a location generally beneath said first connection, said cylinder extending upwardly toward said cradle assembly in the space between said first connection and the pivotal mounting of the cradle frame to the cradle-support structure and having a piston rod pivotally connected to the underside of the cradle frame, said boom assembly including a boom and a torsion bar extended between said boom at said one end of the boom assembly and to a connection to said cradle-support structure, and a tension-setting bolt rotatably attached to said boom and engageable with a bolt step on the cradle-support structure intermediate the connections of the boom and the torsion bar to the cradle-support structure for applying tension to said torsion bar.

A pole-setting apparatus comprising, a boom assembly having a boom connectable at one end to a cradle-support structure, a cradle frame for supporting a pole pivotally-mounted on said cradle frame structure, motor means connected between said cradle-support structure and the cradle frame for causing pivotal movement of the cradle frame to raise a pole carried thereby, a dolly with tires associated with the boom at an end thereof remote from the cradle-support structure, and quick-connection means between said boom and dolly including a pair of spaced-apart plates on said dolly, a connecting plate extended from said boom and of a thickness to fit between said spaced-apart plates, a fixed pin extended between said spaced-apart plates, aligned openings in said spaced-apart plates above said pin, a hook formed on said connecting plate to engage over said pin, an opening in said connecting plate to align with said aligned openings, and a removable pin extended through said openings, at least one of said openings being elongate in a direction generally normal to a radian from said fixed pin to facilitate alignment of the openings for receipt of the removable pin and permit slight pivoting of the dolly relative to the boom.
