54、sm起升機(jī)構(gòu)對(duì)于不同的起吊重量有不同速度，以充分地滿足施工要求。The hoisting mechanism with the function of different speed for different hoisting weight, so that it is applied in different construction projects. QTZ125G(FS6016)塔式起重機(jī)采用了由YZRW225/30KW電機(jī)，通過柱銷聯(lián)軸器帶動(dòng)變速箱（此變速箱采用電磁離合器變檔，可達(dá)三種傳動(dòng)比）再驅(qū)動(dòng)卷筒，使卷筒獲得三種繩速。根據(jù)吊重可選擇不同的滑輪倍率，當(dāng)選用2繩時(shí)，速度可達(dá)到25

55、、50、100米/分三種。若選用4繩時(shí)，速度可達(dá)12.5、25、50米/分三種。為達(dá)到啟動(dòng)和制動(dòng)迅速又平穩(wěn)，在電動(dòng)機(jī)的另一端帶有渦流制動(dòng)器，在變速箱的軸的另一端裝有YWZ-300/45型液壓推桿制動(dòng)器，起升機(jī)構(gòu)不工作時(shí)，制動(dòng)機(jī)構(gòu)永遠(yuǎn)處在制動(dòng)位置。在卷筒軸另一端裝有高度限位器，高度限位器可根據(jù)實(shí)際的需要進(jìn)行調(diào)整。The QTZ125G (FS6016) tower crane adupted the 30Kw motor model YZRW225, through the coupling drive the reducer (the reducer adopts electromagneti

56、sm clutch change, it has three gear ratio) then drive the drum, make the drum gained three speed. It can choice different pulley fall as its hoist weight. When use the rope 2, its speed can reaches 25m/50m/100m per minite. If use the rope 4, its speed can reaches 12.5m/25m/50m per minite. In order to drive it rapidly and placidity, it has brake by eddying on the other side of the motor, the braking
