  • Safety mechanism for a paper stack cart system
    Patent number: 9022718
    Abstract: A safety feature prevents a two wheeled electric paper lift from raising a paper tray on uneven ground that includes a tilt switch positioned in parallel with an upper limit switch that controls the height in a vertical direction of the paper tray. When a tilt angle of the paper lift is greater than 5° the tilt switch will prevent the paper tray from being raised and thereby prevent the load on the paper tray from shifting or tipping over and causing injury to an operator.
