1.施力的合力盡可能通過(guò)液壓升降貨梯軸承的軸線，這就要求施力點(diǎn)均勻?qū)ΨQ(chēng)而平穩(wěn)，通過(guò)球面或平行于軸線施力。As possible to force the axis hydraulic cargo lift bearing, which requires the application point of symmetrical and stable, with spherical or parallel to the axis force.

2.施力的大小宜平穩(wěn)均勻，不宜有沖擊，這就要求采用油壓或用能施加平穩(wěn)拉力或壓力的工具，實(shí)在不得不采用錘擊時(shí)，也要通過(guò)銅套筒等較軟而不落屑金屬加以緩沖，敲擊力盡可能輕緩。最好使用銅棒或銅錘進(jìn)行錘擊。The size of the force should be smooth and uniform, not a shock, which requires the use of oil pressure or tension or pressure can exert a stable tool, we have to use the hammer, but also through the copper sleeve soft scrap metal does not fall into the buffer, strike force as gentle as possible. It is best to use copper or copper hammer.

3.避免通過(guò)滾動(dòng)體施力，這就要求裝拆液壓升降貨梯內(nèi)圈(軸圈)時(shí)通過(guò)內(nèi)圈施力，裝拆外圈時(shí))通過(guò)外圈施力。Through the rolling body to avoid the force, which requires the installation of hydraulic lift cargo ladder inner ring (shaft) when the force through the inner ring, the outer ring of the outer ring.

4.拖力要持續(xù)到應(yīng)有的程度，例如在安裝液壓升降貨梯軸承時(shí)要在軸承剛好裝到正確位置時(shí)停止施力，保證套圈(墊圈)的端面抵靠座孔或軸的擋肩端面，既不能擠得太緊，又不能裝不到位。Drag to continue to the extent, such as the installation of hydraulic lifting elevator bearing when the stop force in the bearing is installed at the correct position, ensure the ring (washer) end against the abutment face hole or shaft, can not packed tightly, they can not be installed in place.
