Abstract:
1. An arm system comprising an arm having a proximal end coupled to a support structure to pivot about a first axis, a first electrically-actuated brake having (i) a braking position to impede pivoting movement of the arm about the first axis, and (ii) a release position to permit pivoting movement of the arm about the first axis, wherein the first electrically-actuated brake is urged to the braking position when the first electrically actuated brake is de-energized, and a service head coupled to a distal end of the arm to pivot about a second axis, the service head including at least one service outlet, a switch operable to energize the first electrically-actuated brake to move the first electrically-actuated brake to the release position.
