Abstract:
1. A machine operator safety system for selectively providing hydraulic power to a boom assembly of an aerial device, the system comprising: a set of upper boom controls disposed in a utility platform that are operable to move the boom assembly via hydraulic power, wherein the utility platform is disposed at a distal end of said boom assembly; a lanyard anchor housing operable to be selectively positioned to a default first position and a second manually actuated position; a lanyard anchor housed within the lanyard anchor housing; an actuator configured to selectively position the lanyard anchor housing in either of the first or second positions, said default first position of the lanyard anchor housing concealing the anchor to prevent attachment of a lanyard by an operator, said second manually actuated position of the lanyard anchor housing exposing the anchor for attachment of the lanyard by the operator; and a hydraulic valve configured to selectively provide hydraulic power to the set of upper boom controls only while the lanyard anchor housing is in the second position.
