Grab bridge bridge crane is running on the elevated track, the car driven by the lifting of materials crawl grab a bridge-crane. Bridge laying on both sides along the elevated track on the vertical run, lifting trolley along the bridge in laying the track on the horizontal run, a rectangular scope of work, you can make full use of space below the bridge lifting material from Ground equipment hindered. Grab bridge cranes widely used in power plants, Mei Chang, and other needs of bulk material handling of the occasion, because of the heavy equipment, transportation difficulties installation, testing the quality of their products in general need in the field. Therefore, control equipment requirements for wiring, small size and portability. And the use of fixed-site conditions, also called a random testing equipment manual control functions to ensure the safety of operation. With the lifting of the transport requirements of the mechanical control continuously improve, more and more advanced means of control. At present the domestic bridge crane control system requires people at the scene to control, control methods are backward. In small and medium-sized crane, the most direct control over the use of controllers, car running, Lord, vice hook upgrade, dropped weights and speed.
