Patent number: 10876913Abstract: A device, system, and method for testing and measuring the grip strength of tongs for a crane system is provided. The device may include a frame body carrying a testing assembly configured to measure the tong grip strength. The system may include the grip strength tester used in conjunction with a crane including an operator tower and a pulley assembly operatively connected to the tongs. The method of use associated with the tong grip strength tester may include the steps of expanding a distance between teeth on the tongs and positioning the teeth adjacent sides of the testing assembly, then closing the tongs thereby clamping teeth to the sides of the testing assembly. Then, the testing assembly measures the compressive force associated with the tongs and registers the compressive force in a computer system to determine whether the grip strength is sufficient to lift a weighted slab of material.Type: GrantFiled: July 24, 2018Date of Patent: December 29, 2020Assignee: Morgan Engineering Systems, Inc.Inventors: Mark Len Fedor, Nelson Elroy Baker, Kenneth Dean Maurer

Publication number: 20140112746Abstract: A system and method for automatically positioning a metal coil into a rail car using stereoscopic image processing is presented. A method begins by picking up the metal coil using a hoist of a crane. The metal coil is then moved to a position over a rail car to where the metal coil will be located. At least one stereoscopic photo is taken of a location in the rail car to where the metal coil will be located. The coil is accurately positioned as it is lowered based on data extracted from the stereoscopic photo(s) to determine where the coil is as it is lowered onto the rail car. The picking up the metal coil, the moving the metal coil to a position over a rail car and the lowering the metal coil into the rail car are performed automatically without human involvement.Type: ApplicationFiled: October 24, 2012Publication date: April 24, 2014Applicant: MORGAN ENGINEERING SYSTEMS, INC.Inventors: Mark Len Fedor, Mark Thomas Sharamitaro, John Junior Kost, Philip Anthony West
