过去,我们场的装卸桥都是卸、选、归一机多用,这给生产带来很大的不便:一是影响生产效率,装卸桥移动幅度大,且无法同时进行多种作业;二是驾驶室在主桁架上,司机视野不好,不利于操作;三是大材小用,机械磨损大等。自从制作了选材小龙吊,这些问题已基本解决。1 选材小龙吊结构选材小龙吊由主桁架、支腿、大车架起升和运行机构等组成。起升机构置于主桁架中部,操作人员站在地面或坐在大车
In the past, our field loading and unloading bridges were all unloaded, selected and returned to a multi-purpose machine, which brought great inconvenience to production. First, it affected the production efficiency, the moving range of the loading and unloading bridge was large, and it was impossible to carry out various operations at the same time. Second, Cab in the main truss, poor driver vision, is not conducive to operation; Third, overkill, large mechanical wear. These problems have basically been solved since the materialistic dragons were produced. A selection of materials, construction equipment, dragons hanging Dragon trusses by the main truss, outrigger, the framework of the lifting and running agencies and other components. Lifting mechanism placed in the middle of the main truss, the operator standing on the ground or sitting in a cart
