登车桥与液压系统有着密切关系的装置，那么登车桥油路是如何设计的呢？

登车桥液压系统的油路走向主要是通过液压泵实现的，它是整个系统的动力元件，也就是为系统提供压力油的。液压泵出口的压力油通过油管直接到达控制阀的进油口，从而在系统中发挥作用，登车桥http://m.iyunsun.com/液压油通过电磁换向阀的口进油，并通过电磁铁通电来控制换向，也就是实现液压油的换向。
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.

为了能使登车桥http://m.iyunsun.com/液压油通过油路块上的接出油管到达液压缸的有杆腔和无杆腔上，所以油路块上一般都会有有PTAB的话，并与执行器接管相接。当液压油流入相应操作部件的时候，就可以启动登车桥的液压动力单元。
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.
