Transports the large-scale components or the heavy installment bridge-type hoist crane in the factory workshop may not attain lacks. along with the modern science technologys rapidly expand, the industrial production scales expansion and automaticitys enhancement, the hoist crane applies in the modernization production process is getting more and more broad, the function is getting bigger and bigger, is also getting higher and higher to hoist cranes request. Especially computer technologys widespread application, many interdisciplines advanced design methods appear, these urge hoist cranes technology to enter the brand-new development phase. the in coor with progress of production proposed actually the hoist crane large cart movement organization as well as king posts several kind of plans, have carried on the design notes through the analysis designation plan and to the large cart movement organization and the king post, simultaneously, also set the request to hoist cranes security check.
