<p>A dual rotary actuator includes a housing having an interior cavity that defines a first tubular chamber having a first axis and a second tubular chamber having a second axis. The second axis is perpendicular to the first axis. A first rotating inner core is provided that is concentrically disposed within the first tubular chamber and has a first rotational axis that coaxial with the first axis. A second rotating inner core is provided that is concentrically disposed within the second tubular chamber and has a second rotational axis that coaxial with the second axis. The housing is mounted to an excavator mounting bracket of the excavator boom with the first rotational axis of the first rotating inner core in an orientation which is transverse to a longitudinal axis of the excavator boom. The second rotating inner core provides a mounting for a working tool.</p> |
