适用于煤矿岩巷掘进的PYZ3/2型凿装机组由煤炭科学研究总院上海分院与湖南湘潭风动机械厂共同开发研制成功。该机组于1990年12月初由湖南省煤炭厅和机械厅联合组织,在湖南白沙矿务局通过技术鉴定。机组是在原耙斗装岩机的基础上修改成液压耙斗装岩机。其泵站除作液压耙斗装岩机的动力源外,也作为两台支腿式液压凿岩机的动力源,同时还可作为其他液压设备的动力源使用,实现了一泵多功能。主机包括两台YYT30支腿式液压凿岩机、一台0.3m~3耙斗装岩机。其主要参数为;
PYZ3 / 2 type chisel unit suitable for coal rock roadway excavation was successfully developed jointly by Shanghai Branch of Coal Science Research Institute and Hunan Xiangtan Pneumatic Machinery Factory. The unit was jointly organized by Hunan Coal Office and Machinery Department in early December 1990 and passed the technical appraisal at Hunan Baisha Mining Bureau. The unit is modified into a hydraulic rake bucket rock loader on the basis of the original rake bucket rock loader. Besides being the power source of the hydraulic rake bucket rock loader, the pump station also serves as the power source of two leg hydraulic rock drills and can also be used as the power source of other hydraulic equipment to realize the multi-function of a pump. Host includes two YYT30 leg hydraulic drill, a 0.3m ~ 3 rake bucket rock loader. Its main parameters are;
