Single hydraulic prop
DW型外注式单体液压 支柱是一种外供液恒阳式支柱，5HDJA或HDIC金属顶梁配合，用于煤矿井下回采工作面顶板支护，亦可用于综采综放工作面端头支护或临时支护。
DW型外注式单体液压支柱己形成Φ100和Φ110mm两大系列。
DW type external injection single hydraulic prop is a kind of external liquid supply constant sun prop, 5HDJA or HDIC metal roof beam matching, used for coal mine stoping face roof support, can also be used for fully mechanized caving face end support or temporary support.
DW type external injection single hydraulic prop has formed Φ100 and Φ110mm two series.
