US 6,530,742 B2 · Telescopic boom routing assembly for transmission lines

Abstract

A telescopic boom arrangement of a vehicle is provided with a fixed, tubular outer boom and an inner boom which is mounted for sliding within the outer boom. Transmission lines for coupling various functions, carried at the end of the inner boom, with a power source/and or controls include an intermediate section mounted to the outer boom by a transmission line routing assembly which holds first ends of the intermediate section of the transmission lines at a fixed location and establishes a guide along which second ends of the section of transmission lines is moveable lengthwise of the outer boom. The intermediate section of the transmission lines is flexible and defines a bow which changes in length as the inner boom extends and retracts relative to the outer boom.
