登車橋與液壓系統有著密切關系的裝置，那么登車橋油路是如何設計的呢？

登車橋液壓系統的油路走向主要是通過液壓泵實現的，它是整個系統的動力元件，也就是為系統提供壓力油的。液壓泵出口的壓力油通過油管直接到達控制閥的進油口，從而在系統中發揮作用，登車橋http://www.lilacred.com/液壓油通過電磁換向閥的口進油，并通過電磁鐵通電來控制換向，也就是實現液壓油的換向。
Ramps to the oil hydraulic system is mainly achieved through the pump, it is the dynamic components of the system, that is, the system provides the pressure of the oil. Pressure oil pump outlet tubing to reach through direct control of the inlet valve, and thus play a role in the system, Ramps hydraulic oil into the oil solenoid valve through the mouth and through the solenoid is energized to control the commutation, also is the realization of the hydraulic oil commutation.

為了能使登車橋http://www.lilacred.com/液壓油通過油路塊上的接出油管到達液壓缸的有桿腔和無桿腔上，所以油路塊上一般都會有有PTAB的話，并與執行器接管相接。當液壓油流入相應操作部件的時候，就可以啟動登車橋的液壓動力單元。
In order to make Ramps hydraulic oil to reach the cylinder through the tubing connected to a manifold on the rod chamber and has rodless cavity, so the manifold generally have had PTAB then, and with the actuator takeover phase. When the hydraulic oil into the corresponding parts of the operation, you can start a hydraulic dock leveler hydraulic power unit.
