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

Patent number: 7783003Abstract: In one example, a radiation scanning system and method rotates a cargo conveyance after removal from a ship for proper orientation with respect to a scanning source and detector, for scanning. A movable carriage may be provided on a crane system, to rotate the cargo conveyance. A rotating flywheel on the carriage rotates in a direction opposite the direction of rotation of the cargo conveyance, to counterbalance angular momentum generated by the rotating conveyance, to avoid or minimize twisting of the carriage. Feedback is provided to control the rotation of the flywheel. Once the cargo conveyance is in the predetermined position, the conveyance is moved between the radiation source and detector for scanning by a vertically extending radiation beam.Type: GrantFiled: September 24, 2007Date of Patent: August 24, 2010Assignee: Varian Medical Systems, Inc.Inventors: James E.

Patent number: 7410339Abstract: The invention relates to a transfer plant, especially for loading and unloading ISO containers from container ships at seaports, comprising a vertical support which is propped up on the land side and on which a horizontal extension arm is braced. Said horizontal extension arm, along which a horizontal conveying device can be displaced, protrudes across the ship that is to be unloaded on the sea side. The horizontal conveying device cooperates with hoisting and lowering devices which pick up and put down the containers. The aim of the invention is to create a redesigned transfer plant and a method for loading and unloading containers, preferably ISO containers, from container ships in seaports, which allow the transfer rate to be significantly increased and consequently the lay times of the container ships at the pier to be substantially reduced. Said aim is achieved by disposing at least two horizontal conveying devices (9, 10) on the horizontal extension arm (1.4, 1.5, 1.Type: GrantFiled: August 28, 2003Date of Patent: August 12, 2008Assignee: Gottwald Port Technology GmbHInventors: Hermann Franzen, Joachim Kröll

Patent number: 5706736Abstract: Disclosed is a polar crane supported by a rail and having a bridge and a bridge-supporting end truck at each end of the bridge. Each end truck has, for either direction of revolving bridge motion, a leading wheel contacting the rail. In the improvement, the leading wheel of each end truck has a single flange and the flange is inward of the rail. Skewed crane "lock-up" is thereby substantially prevented. A related method for modifying a polar crane includes raising the first end truck away from the rail, removing a two-flange wheel (the leading wheel) from the first end truck and installing a one-flange wheel in place thereof.Type: GrantFiled: January 11, 1996Date of Patent: January 13, 1998Assignee: Harnischfeger CorporationInventor: George E.
