升降貨梯在園林、工廠、碼頭、商場(chǎng)應(yīng)用廣泛，但是在使用過(guò)程中，往往會(huì)伴隨著升降晃動(dòng)、不穩(wěn)等現(xiàn)象，下面有關(guān)技術(shù)人員給大家介紹一下貨梯的忽略因素有哪些？

1、上、下作業(yè)臂、支腿、輪胎等都具有足夠的剛度，不考慮升降貨梯的柔性，液壓缸的質(zhì)量變幅很小，不會(huì)對(duì)升降不穩(wěn)產(chǎn)生影響，忽略不計(jì)。
Zhejiang freight elevators, under the working arm, leg, tires and so has sufficient rigidity, without regard to cargo lifter flexibility, quality luffing cylinder is small, does not affect the lifting instability, is negligible.
 
2、作業(yè)時(shí)，用4條支腿作支撐，而所有輪胎都完全離開(kāi)地面，將工作平臺(tái)及其載荷看作一個(gè)集中載荷固結(jié)在上作業(yè)臂末端。
Zhejiang, freight operations, with four legs for support, and all the tires are completely off the ground, the work load of the platform and its consolidation as a concentrated load on the working arm ends.
 
3、上、下作業(yè)臂為勻質(zhì)桿狀結(jié)構(gòu)，其質(zhì)心在各臂的幾何中心位置將工作平臺(tái)及其載荷看作一個(gè)集中載荷固結(jié)在上作業(yè)臂末端。
Upper and lower operating arm of homogeneous rod-shaped structure, its center of mass at the geometric center of each arm will work platform and its load as a concentrated load consolidation in the working arm ends.
