随着露天采矿工作的发展,主要采矿机械——剥离和采矿作业电铲的作用日益增大,因而促进了矿山电铲制造业的迅速发展。改进电铲结构的主要方向是,用增大铲斗容积和臂长以及提高工作机构的灵活性来增大单机功率和生产能力。同时,对大型电铲的控制自动化也予以重视。 With the development of open pit mining, the role of power shovels, the major mining machinery - stripping and mining operations, has been increasingly enhanced, thus contributing to the rapid development of the mining shovel manufacturing industry. The main direction to improve shovel structure is to increase stand-alone power and throughput by increasing bucket volume and arm length and increasing work mechanism flexibility. At the same time, the control of large power shovels also take the automation.
