  • Vacuum-operated vehicle glass handling system
    Patent number: 7628434
    Abstract: A vacuum-operated vehicle glass handling system includes a plurality of suction cups movably disposed on a frame. A powered vacuum source is fluidly connected to the plurality of suction cups for providing a vacuum at each of the plurality of suction cups. A powered vacuum source includes a pair of vacuum pumps both fluidly connected to the plurality of suction cups for redundantly providing the vacuum to the plurality of suction cups. A power source is selectively electrically connected to the powered vacuum source. A pair of vacuum actuators is on the frame for selectively electrically connecting the power source to the powered vacuum source so the powered vacuum source can provide the vacuum at the plurality of suction cups. The power source is electrically connected to the powered vacuum source upon actuation of one or both of the pair of vacuum actuators. A pair of release actuators is on the frame for selectively releasing the vacuum provided at the plurality of suction cups.
