Patent number: 10423134Abstract: An intermediate sump warning system having a sensor associated with a gate of an intermediate sump. The sensor is connected to a controller that activates a warning signal when the sensor detects that the gate is in an open position. The controller also deactivates the unloading system when the gate is open.Type: GrantFiled: January 2, 2018Date of Patent: September 24, 2019Assignee: Sukup Manufacturing Co.Inventors: Eugene G. Sukup, Graham Giddings, Elizabeth Brinkman, Randal L. Marcks, Charles E. Sukup

Patent number: 10302177Abstract: A friction driven beltless grain spreader system is presented that includes a spreader cone having a pulley and a grain deflector configured to disperse the flow of grain. A motor having a driven wheel and an idler wheel are pivotally connected to the spreader cone in operative engagement with the pulley such that the idler wheel is positioned between the driven wheel and the pulley. A tension member applies a force that pulls the driven wheel and intermediary wheel into the pulley. As the motor rotates the driven wheel rotates the idler wheel which rotates the pulley. When forces spike, such as when the motor is turned on or a heavy flow of grain hits the system, one or more of the driven wheel, intermediary wheel and/or pulley slip with respect to the other wheels thereby preventing breakage of the system.Type: GrantFiled: November 3, 2017Date of Patent: May 28, 2019Assignee: SUKUP MANUFACTURING CO.Inventors: Matthew Koenen Koehler, Randal L. Marcks

Publication number: 20120163947Abstract: A sweep control system having a sweep auger rotationally mounted about a central axis of a center sump and operatively connected to pusher motor(s). A sensor measures the load on the sweep auger and sends a signal to the controller. The controller compares the detected load to a predetermined load and sends a signal to a variable speed drive based on the comparison. The variable speed drive is connected to the pusher motor(s) and adjusts the speed of the pusher motor(s) based upon the received signal.Type: ApplicationFiled: December 22, 2010Publication date: June 28, 2012Applicant: SUKUP MANUFACTURING COMPANYInventors: Matthew R. Koch, Randal L. Marcks, Charles E. Sukup

Patent number: 8123260Abstract: A latch apparatus for releasably securing a cover member over an access opening in a bulk storage structure. The latch apparatus is pivotally mounted to a cover member and includes a pair of latch members and a latch bar connected to and extending between the latch members. The latch members have a receptacle that receives a catch member and an extension that extends away from the latch member opposite the receptacle. The extension engages the cover member when the latch member is moved from a locked position to an unlocked position to prevent injury to a user.Type: GrantFiled: March 13, 2009Date of Patent: February 28, 2012Assignee: Sukup Manufacturing Co.Inventors: Randal L. Marcks, John A. Hanig, Charles E. Sukup
