升降貨梯在園林、工廠、碼頭、商場應用廣泛，但是在使用過程中，往往會伴隨著升降晃動、不穩(wěn)等現(xiàn)象，下面有關技術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，液壓缸的質量變幅很小，不會對升降不穩(wěn)產生影響，忽略不計。
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，用4條支腿作支撐，而所有輪胎都完全離開地面，將工作平臺及其載荷看作一個集中載荷固結在上作業(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)臂為勻質桿狀結構，其質心在各臂的幾何中心位置將工作平臺及其載荷看作一個集中載荷固結在上作業(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.
