1. A truck loading system comprising support;

  • a bin carried by said support in an elevated position at a truck loading station for discharging flowable material into a truck disposed under the bin, said bin having a gate openable and closable to control flow of said material out of the bin and into the truck;

    electromechanical means arranged to open and close the gate;

    electrically operated signal means connected in circuit with said electromechanical means to signal when the gate is closed upon filling the truck to a predetermined level at any loading position;

    a tilt switch loading probe suspended below the bin to sense when the truck is filled to said predetermined level, said probe containing switch means responsive to tilt of said probe at an angle in a vertical plane through a horizontal range of 360*; and

    circuit means interconnecting the probe signal means and electromagnetic means, so that the gate is closed and the signal means is actuated when the probe is tilted by said mAterial rising to said level in the truck, said truck having a rear wall, and further comprising another tilt switch probe suspended below the bin to contact said wall and sense when the truck has moved in to a final fully loaded position;

    other signal means connected in circuit with the other probe to signal that the truck is fully loaded; and

    other circuit means interconnecting said other tilt switch probe, other signal means, and first named circuit means to actuate said other signal means and to lock said gate closed, while the loaded truck is driven away from said loading station.
