    摘要: A long-span structure engaged with a plurality of first and second transportation devices for moving the long span structure. The transportation devices travel along parallel, longitudinally-oriented first and second tracks; moving the structure between a first position and a second position. A first region of the structure is fixed to each first transportation device. A second region of the structure is secured to each second transportation device via a bearing assembly. The first and second regions of the structure are laterally spaced apart. When the long-span structure thermally expands or contracts, a slider plate of each bearing assembly moves laterally relative to the rest of the bearing assembly. Growth of the structure in a predictable direction is forced by keeping the first region thereof fixed against lateral movement with the first transportation devices and allowing movement of the second region thereof via the bearing assemblies on the second transportation devices.

    摘要: 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.

    摘要: 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.
