暗桿式(shi)啟(qi)閉機(ji)(ji)(ji)又稱為暗桿啟(qi)閉機(ji)(ji)(ji)、暗桿式(shi)螺桿啟(qi)閉機(ji)(ji)(ji)，按(an)吊(diao)點(dian)(dian)數(shu)分為單吊(diao)點(dian)(dian)和雙吊(diao)點(dian)(dian)兩種(zhong)(zhong)型號，按(an)驅動方(fang)式(shi)分為手(shou)(shou)動、 電動和手(shou)(shou)電兩用三種(zhong)(zhong)形式(shi)，一般(ban)噸(dun)位超過(guo)60T(單機(ji)(ji)(ji))時不再配置(zhi)手(shou)(shou)動部分。我(wo)公司(si)生(sheng) 產的QL型系列啟(qi)閉機(ji)(ji)(ji)啟(qi)門(men)力(li)為0.3T-65T，超過(guo)65T(單機(ji)(ji)(ji))時可特殊設(she)計。

暗桿啟閉機廣泛用于各(ge)類給排水和水利(li)、水電(dian)(dian)工(gong)程中(zhong)，主要用來控(kong) 制(zhi)各(ge)類閘門的升降(jiang)，實現(xian)閘門的開啟和關閉。形(xing)式(shi)有手(shou)推式(shi)、側搖式(shi)、 全封閉式(shi)、手(shou)搖手(shou)電(dian)(dian)兩(liang)用式(shi)，平原山區(qu)、有電(dian)(dian)無電(dian)(dian)均可使用。
