我国首台WKC—6(原名WP—6)大型齿条推压长臂挖掘机,于1988年底在太原重型机器厂总装负荷试车表明,达到了设计要求。该机的工作重量为501t、理论生产率为640m~3/h、铲斗容积为6m~3、起重臂长22m(倾角55°)、斗杆长度为13.2m、工作循环时间为34s、最大卸载高度为17.7m、最大挖掘深度为3.6m、最大挖掘高度为23.4m、最大挖掘半径为24.25m。 China’s first large WKC-6 (formerly WP-6) large-scale rack-and-pinion long-arm excavator, at the end of 1988 in Taiyuan heavy machinery plant assembly load test showed that the design requirements. The machine has a working weight of 501t, a theoretical productivity of 640m ~ 3 / h, a bucket capacity of 6m ~ 3, a boom length of 22m (inclination angle of 55 °), an arm length of 13.2m and a working cycle time of 34s, Unloading height of 17.7m, the maximum excavation depth of 3.6m, the maximum excavation height of 23.4m, the maximum excavation radius of 24.25m.
