A project funded by the Electric Power research Institute has produced a working prototype of a pantograph linkage supported, telescopic pole type tool with interchangeable cutting heads for trimming trees around electrical conductors. The tool is designed for mounting on the bucket of an aerial lift of the type commonly used for tree trimming. The three-section telescopic pole is constructed of non-conductive, filament wound, fiber-glass reinforced epoxy and is adjustable from an overall length of 7 feet to a fully extended length of 17 feet. The project goal was to obtain a 20% improvement in productivity of tree crews. Productivity gains are expected to result from fewer truck set-ups, faster tool positioning, and reduced user fatigue. The next phase of the project will involve test and evaluation of the prototype and will quantify actual productivity gains.
