Sep 4,2023
Note: Because the boom cylinder is extended and retracted in place before oil is discharged, only one chamber of all boom cylinders is filled with oil; the other chamber is filled with oil due to the expansion and contraction of the oil cylinder, so the volume of oil contained in the other chamber is very small and can be ignored. . For example: the boom cylinder is extended in place before oil discharge, so when draining oil, you only need to consider removing the oil contained in the rodless cavity of the pump truck's boom cylinder.
â–ºDrain oil from other boom cylinders

If the space is limited, after the rotation and boom are drained, the oil in the outrigger pipeline can be drained directly, and then the pump truck can be driven to an open space to continue draining oil;

To drain oil from other boom cylinders, please refer to the oil draining method of one arm cylinder.
