铝合金升降机采用的都是液压的动力形式，液压油缸也是根据不同的机器进行定制的，所以不同的设备所使用的液压油缸大小和长度也不相同。决定液压缸大小的因素主要是载重量，一个合适的载重量配合着一个合适的液压动力，但因为他们是相互影响的，但有一些铝合金升降机的油缸的数量和长度根升降的高度也有关系。升降的高度越高，则油缸的数量越多，长度也会增加。
Aluminum Alloy lifts are used in the form of hydraulic power, the hydraulic cylinder is customized according to different machines, so the hydraulic cylinder size and length of use of different equipment is not the same. Factors that determine the size of the hydraulic cylinder is mainly carrying capacity, a suitable load with a suitable hydraulic power, but because they are mutual influence, but some aluminum alloy elevator cylinder number and length of root lifting height. The lifting height is, the more the number of the oil cylinder length will increase. 

铝合金升降机液压系统的压力不是随便设定的，主要是考虑到材质的问题，压制指数越高，说明制作的材料越好，越精致，不然差的材料非常容易发生爆裂的危险。不同的空间可以根据以下的公式：作用力=压力*面积，这里的面积就是因为铝合金升降机的空间限制跟控制住了，所以压力越大，作用力一般也就越大。而作用力是根据所要运送的货物重量计算的，铝合金升降机买之前你预估货物大概有多少重量，或者直接拉到地磅上直接称量一下都可以，然后再确定选用哪种液压缸。
Aluminum alloy elevator hydraulic system pressure not just set, mainly considering material and suppression index higher, making better the materials, more delicate, or poor materials very prone to danger of bursting. Different space can be based on the following formula: force = pressure * area, where the size of the area is because of the aluminum alloy elevator control space constraints, so the greater the pressure, the greater the force. And the force is calculated according to the weight of goods to be transported, aluminum alloy elevator before buying you anticipate about how much weight of goods, or directly to loadometer on direct weighing my, and then determine the selection of what kind of hydraulic cylinder.
