  • Patent number: 8104809
    Abstract: A manually activated suction lifting device has a handle which rotates up to complete an active suction. The first stage of the suction is created by pushing firmly down on the convex top of the device. Upon creation of the final suction with the handle locked up, an alarm button is drawn into the housing, hiding an alarm ring. If the suction fails, then a vent tube transmits the lost vacuum to an alarm chamber, thereby allowing a spring to bias the alarm button outbound, exposing the alarm ring to a worker so he can grab the workpiece and prevent damage.
