重庆升降机在上货时，会产生下沉，下沉量受载重、产品加工精度、油缸质量和金属主体承载结构等因素影响。
剪叉式液压升降货梯是目前使用非常广泛的一种货物垂直运输设备，它价格低，载重量大、安装简单，受到用户喜爱，单剪叉式液压升降货梯有一个很大的缺点：载货后下沉量很大，影响货物进出。影响剪叉式液压升降货梯下沉量的因素主要有载重量、设备主体金属结构、油缸质量、设备加工精度等原因。
Scissor hydraulic cargo lift is very widely used as a cargo vertical transportation equipment, its low price, carrying capacity, easy installation by the user favorite, single scissor hydraulic cargo lift has a big drawback: Cargo after sinking a large amount, the impact of goods in and out. Hydraulic Scissor Lift affect freight subsidence of the main factors that have deadweight,equipment main metal structure, fuel tanks quality, precision machining equipment and other reasons.
剪叉式液压升降货梯的特殊结构，决定了载货后设备必然会下降，一般来说，金属都有弹性伸缩特点，载货后，受重力影响，设备的金属结构会产生弹性变形，表现就是升降货梯下沉，载货量越大，下沉量越大，为了降低下沉量，在产品设计时，适当增加安全余量，能有效减小下沉量。
Scissor hydraulic lift freight special structure, the decision is bound to decline after the loading equipment, in general, metals have elastic stretch characteristics, the cargo, subject to the influence of gravity, metal structures and equipment will produce elastic deformation, the performance is Huoti sink, the greater cargo capacity, the greater the amount of subsidence, in order to reduce the amount of subsidence in product design, appropriate to increase the safety margin, can effectively reduce the amount of subsidence. 
油缸质量是影响下沉量的一个主要因素，载货后，油缸内压力很大，如果油缸的加工精度低或油缸的密封质量差，造成油缸内泄或外泄，会加大剪叉式液压升降货梯的下沉量，为了减小油缸的影响，在选择油缸时，尽量选择大厂的产品，密封件尽量选择进口产品，把油缸的影响降到最小。
Cylinder quality is a major factor affecting the amount of sinking, after loading, the fuel tank pressure, if the fuel tank is low or poor precision sealing quality cylinder, causing the fuel tank vent or leakage will increase Scissor Huoti of subsidence, in order to reduce the impact of the fuel tank, in the choice of the cylinder, try to choose products manufacturers, seals try to choose imported products, to minimize the impact of the fuel tank. 
加工精度也是影响剪叉式液压升降货梯下沉量的一个重要因素，相同的配置，不同的厂商，生产出来的产品，下沉量不一样，为什么，加工精度不一样。轴销和轴承间间隙过大，会加大设备的下沉量；不同的工艺，不同的工人制作出来的设备，焊接变形程度不一样，下沉量自然不一样。
Machining accuracy is also an important factor in hydraulic cargo lift Scissor subsidence effects, the same configuration, different vendors, products produced, subsidence is not the same, why is not the same precision. Axle pin and the bearing clearance is too large, it will increase the amount of subsidence equipment; different processes, different workers produced equipment, welding deformation degree is not the same, not the same as natural subsidence.
