重慶升降機在上貨時，會產生下沉，下沉量受載重、產品加工精度、油缸質量和金屬主體承載結構等因素影響。
剪叉式液壓升降貨梯是目前使用非常廣泛的一種貨物垂直運輸設備，它價格低，載重量大、安裝簡單，受到用戶喜愛，單剪叉式液壓升降貨梯有一個很大的缺點：載貨后下沉量很大，影響貨物進出。影響剪叉式液壓升降貨梯下沉量的因素主要有載重量、設備主體金屬結構、油缸質量、設備加工精度等原因。
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.
剪叉式液壓升降貨梯的特殊結構，決定了載貨后設備必然會下降，一般來說，金屬都有彈性伸縮特點，載貨后，受重力影響，設備的金屬結構會產生彈性變形，表現就是升降貨梯下沉，載貨量越大，下沉量越大，為了降低下沉量，在產品設計時，適當增加安全余量，能有效減小下沉量。
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. 
油缸質量是影響下沉量的一個主要因素，載貨后，油缸內壓力很大，如果油缸的加工精度低或油缸的密封質量差，造成油缸內泄或外泄，會加大剪叉式液壓升降貨梯的下沉量，為了減小油缸的影響，在選擇油缸時，盡量選擇大廠的產品，密封件盡量選擇進口產品，把油缸的影響降到最小。
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. 
加工精度也是影響剪叉式液壓升降貨梯下沉量的一個重要因素，相同的配置，不同的廠商，生產出來的產品，下沉量不一樣，為什么，加工精度不一樣。軸銷和軸承間間隙過大，會加大設備的下沉量；不同的工藝，不同的工人制作出來的設備，焊接變形程度不一樣，下沉量自然不一樣。
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.
