由陕西省建筑科学研究所研究设计,经哈尔滨国营建成机械厂试制成功的QTS60型塔式起重机,一九八三年五月通过省级技术鉴定。一、QTS60型塔机的主要特点 1.性能良好 (1)采用升降式司机室,可使驾驶人员视野宽广、上下方便。 (2)起升机构采用本所在国内首次研制成功的起重用绕线式双速电机和鸟啄式涡流制动器调速,使起升操作具有六种不同速度,性能好、功效高。 (3)回转和行走机构采用阀控延充式液力联轴器,使塔机回转和行走的起动和停车安全、平稳。
The QTS60 tower crane was successfully designed and manufactured by the Shaanxi Institute of Construction Science and Technology, successfully completed by the Harbin State Construction Machinery Plant. In May 1983, it passed the provincial technical appraisal. First, the main features of the QTS60 type tower crane 1. Performance is good (1) The use of lift-type driver’s cab, allowing drivers to have a wide field of vision, convenient up and down. (2) The hoisting mechanism adopts the winding speed type two-speed motor and bird-winding eddy current brake which were developed for the first time in the country. The hoisting operation has six different speeds, good performance and high efficiency. (3) Swing and running mechanism adopts valve-controlled delay-filled hydraulic coupling, which makes the tower crane’s rotation and walking start and stop safe and stable.
