由煤科院上海研究所设计、北京煤矿机械厂制造的HZY32/320型支撑掩护式液压支架,最近在北京通过技术鉴定。该支架是为与MG150和MLS3PH-170型采煤机的合理配套而研制的ZY系列液压支架新品种。适用于煤层厚度1.8～3m,倾角25°以下的Ⅱ级二类顶板的长壁式开采(大于15°时需配装防倒防滑装置)。支架初撑力2410kN,工作阻力3200kN,支架强度0.63
Designed by Shanghai Institute of Coal Science Research Institute, HZY32 / 320 type support shield type hydraulic support manufactured by Beijing Coal Mining Machinery Factory passed the technical appraisal in Beijing recently. The bracket is a new type of ZY series hydraulic support developed for reasonable cooperation with the MG150 and MLS3PH-170 shearer. It is suitable for the longwall mining of Grade II II roof with coal seam thickness of 1.8 ~ 3m and inclination less than 25 ° (it is required to be equipped with anti-skid device when it is more than 15 °). Bracket initial strength 2410kN, working resistance 3200kN, stent strength 0.63
