太原重型机器厂自行设计制造的WQ80/45履带起重机于1985年1月31日在厂内进行了总装负荷试车、证明性能达到了设计要求。该厂是我国生产大型挖掘机的主要厂家,迄今已生产了五百多台。为了进一步提高挖掘机的整机性能,该厂在整顿WK-4型挖掘机的基础上,改型为WK-4A型。同时,为了满足水电站和矿山等用户的需要,扩大该设备的使用范围,设计制造了WQ80/45履带起重机。这种设备适用于起重工程较为集中的工地现场。尤其对于大型水电建筑工地,该机在第一期土方工程中可作为采掘机械使用,在第二期和第三期工程中,可作为起重机械来 Taiyuan Heavy Machinery Factory designed and manufactured WQ80 / 45 crawler cranes on January 31, 1985 in the factory assembly load test run to prove that the performance has reached the design requirements. The plant is a major manufacturer of large excavators in China, so far produced more than 500 units. In order to further improve the overall performance of excavators, the plant in the rectification of WK-4 excavators based on the modified WK-4A type. At the same time, in order to meet the needs of hydropower stations and mines and other users, to expand the scope of the equipment used to design and manufacture of WQ80 / 45 crawler cranes. This equipment is suitable for lifting work is more concentrated site site. Especially for large hydropower construction sites, the aircraft can be used as mining machinery in the first phase of earthworks, in the second and third phase of the project, can be used as lifting machinery
