  • Patent number: 7915752
    Abstract: The present invention provides a control circuit for enabling an aerial boom on an aerial lift truck having stabilizing members. The control circuit includes a selector switch to enable the auxiliary member and an interlock portion preventing the auxiliary member from being enabled if each of the stabilizing members is not in an operative position. The control circuit further includes an interlock over ride. The interlock over ride may be activated when the selector switch is attempting to enable the auxiliary member and remains activated until the selector switch disables the auxiliary member. Thus, the interlock over ride permits an operator to bypass the interlock during a single operation of the auxiliary member and prevents bypass from remaining active during subsequent operations of the auxiliary member.
