QPT型臺車(che)卷(juan)揚(yang)(yang)啟閉機,卷(juan)揚(yang)(yang)機（又叫絞車(che)）是由人力(li)(li)或(huo)機械動(dong)(dong)力(li)(li)驅(qu)動(dong)(dong)卷(juan)筒、卷(juan)繞(rao)繩(sheng)索來完成牽引工作的(de)裝置(zhi)。可以垂直提升(sheng)、水平或(huo)傾(qing)斜(xie)拽引重物。卷(juan)揚(yang)(yang)機分為手動(dong)(dong)卷(juan)揚(yang)(yang)機和(he)電動(dong)(dong)卷(juan)揚(yang)(yang)機兩種。現在以電動(dong)(dong)卷(juan)揚(yang)(yang)機為主。電動(dong)(dong)卷(juan)揚(yang)(yang)機由電動(dong)(dong)機、聯(lian)軸節、制動(dong)(dong)器(qi)、齒輪箱和(he)卷(juan)筒組成，共同安裝在機架(jia)上。對(dui)于起升(sheng)高(gao)度和(he)裝卸量大工作頻繁的(de)情(qing)況(kuang)，調(diao)速性能好，能令空鉤快速下(xia)降。對(dui)安裝就位或(huo)敏感的(de)物料，能用較小速度。
