Insulated boom knuckle cover for high voltage line truck

1. An insulated boom knuckle cover for high voltage line truck comprising an insulated sheathing unit attachable overtop of a knuckle of an articulated boom arm used for extending a bucket lift for maintenance and repair of high voltage lines, said insulated sheathing unit comprising:

an upper section attachable to the boom arm, said upper section including a longitudinally disposed plurality of corrugations; and

an arched knuckle cover section disposed extended from the upper section to overlie and shield the knuckle of the boom arm from contact with high voltage lines during extension of the bucket lift;

whereby said upper section contacts the boom arm only along each of said plurality of corrugations.

2. The insulated boom knuckle cover for high voltage line truck of claim 1 wherein the upper section attaches overtop the boom arm proximal the knuckle by action of a plurality of strap members disposed to adjustably fasten together around the boom arm and secure the upper section in position shielding the boom arm from direct contact with high voltage lines during extension of the bucket lift.

3. The insulated boom knuckle cover for high voltage line truck of claim 2 wherein the arched knuckle cover includes a first portion, disposed extending the upper section to overhang the knuckle of the boom arm, and a lowermost portion disposed at an obtuse angle relative the first portion, said lowermost portion disposed to overlie and shield the knuckle of the boom arm when said boom arm is disposed in a lowered, folded position, and maintain shielding of said knuckle of the boom arm when the boom arm is extended away from the lowered, folded position.

4. The insulated boom knuckle cover for high voltage line truck of claim 3 wherein the plurality of strap members includes ratchet clamps usable to effect taut securement of the upper section at an appropriate location to depend the arched knuckle cover section overtop the knuckle of the boom arm.

5. The insulated boom knuckle cover for high voltage line truck of claim 4 wherein the upper section and arched knuckle cover are rendered of fiberglass.

6. The insulated boom knuckle cover for high voltage line truck of claim 4 wherein the upper section and arched knuckle cover are rendered of nonconductive polymer.

7. An insulated boom knuckle cover for high voltage line truck comprising:

an insulated sheathing unit attachable overtop a knuckle of an articulated boom arm used for extending a bucket lift to effect maintenance and repair to overhead high voltage lines, said insulated sheathing unit comprising:

an arched fluted upper section attachable to the articulated boom arm above the knuckle, said upper section having:

a convex exterior surface;

a concave interior surface;

a plurality of corrugations disposed longitudinally upon the interior surface, each of said plurality of corrugations disposed to contact atop the boom arm and maintain the upper section away from contact with the boom arm in between each of said plurality of corrugations;

a pair of side wall sections disposed sideway longitudinally bounding the upper section;

a plurality of strap members disposed interiorly upon the interior surface at an attachment point disposed thereon, each of said plurality of strap members having at least a first strap part and a second strap part securable together around the boom arm to effect taut attachment of the upper section thereto; and

an arched knuckle cover section disposed extended from the upper section and disposed to overlie the knuckle of the articulated boom arm, said knuckle cover section having:

a first portion disposed coplanar with the upper section; and

a lowermost section disposed at an obtuse angle relative the first portion;

wherein the upper section is securable to the boom arm proximal the knuckle and the knuckle cover section is maintainable in an appropriate position to shield the knuckle from contact with a high voltage line to which the bucket lift is oriented by a user, whereby arcing from proximity of the knuckle relative the high voltage line and direct contact with said high voltage line during orientation of the bucket lift is avoidable.
