The promotion way:

1、機械提升

1, mechanical lifting

該提升機構由電動機、減速器、齒輪付、絲桿和固定螺母組成。提升時，電動機正轉，帶動減速器、齒輪，使絲桿在固定絲母中轉動，推動提升。

The lifting mechanism is composed of motor, reducer, gear, screw and a fixing nut. When lifting, motor forward rotation, drive reducer, gear, the screw rod to rotate on the fixed screw, promote.

2、液壓提升

2, hydraulic lifting

液壓提升機構的組成由液壓站、油缸、活塞、活塞桿以及活塞桿與提升板連接的哈夫蘭卡片。液壓提升機械提升時，由液壓站供高壓油，當壓力大于提升板運行的摩擦阻力時，提升板緩慢地提升這時，切斷電機電源，提升動作完成。

The hydraulic lifting mechanism is composed of a hydraulic station, hydraulic cylinder, piston, piston rod and the piston rod and the lifting plate connected havran card. Hydraulic lifting machinery lifting, a hydraulic station for high pressure oil, when the pressure is greater than the friction plate lifting operation, lifting plates slowly ascension at this time, cut off the motor power supply, enhance the action completion.

3、手動提升：是以螺旋式機械千斤頂推動提升板將濾板提升。

3, manual lifting: in a spiral type mechanical jack promote plate filter plate lifting.

卷揚機的結構構造中，提升結構是其生產和發展的主要動力，在其工作過程中表現出了極為重要的特點，上面的三種提升方式主要是根據其工作方式的不同而進行劃分的。不同的劃分方式可以劃分為不同的類型

The structure of hoist, lifting structure is the main power of its production and development, in the course of their work shown extremely important characteristics, three kinds of ways to enhance the above is classified according to its different ways of working. Division in different ways can be divided into different types
