Abstract:
An arrangement for determining the relative angular orientation of an excavator bucket with respect to a dipper stick of an excavator, comprising:an excavator with a dipper stick;an excavator bucket being mounted on a bucket linkage pivotally secured to an end of the dipper stick, the excavator including an hydraulic actuator having an hydraulic cylinder pivotally connected to said dipper stick and a piston rod pivotally connected to said bucket linkage, whereby extension or contraction of said hydraulic actuator causes said excavator bucket to be pivoted by said bucket linkage with respects to said dipper stick,a cable extension linear position transducer having a transducer casing, a sheath extending from said casing, and an extensible cable including a first cable portion extending from said transducer casing, an a second cable portion extending from said sheath, said first and second cable portion being attached together within said sheath by clips, said transducer providing an electrical output related to the extension of said cable from said sheath,a transducer mounting for securing said casing of said extension linear position transducer in fixed relationship to said hydraulic cylinder, anda clip for securing said extensible cable to said piston rod of said hydraulic actuator, whereby extension or contraction of said hydraulic actuator causes the electrical output of said transducer to vary, thus providing an electrical output indicating the relative angular orientation of said excavator bucket with respect to said dipper stick.
