Continuous Hydraulic Supply
The CBW controller can be used to set and adjust a constant hydraulic feed to a tip-trailer. This
is not standard, it must be ordered as an extra option.
The hydraulic supply is not the same as tipping or lowering a trailer. When the trailer is simply
lowered or tipped, a hydraulic feed is provided only during the time the function is activated. In
contrast, the hydraulic supply is constantly fed to the tip-trailer and can be either increased or
decreased as required.
The hydraulic supply to a tip trailer is normally fed from the hook-lift's connector on the back of
the vehicle.
The CBW controller is used to control the flow of hydraulic fluid to the tip-trailer. The flow is ini-
tially set at 0L/min and must be set to the required value by the driver using the tip trailer icons.
Refer to Table 5.
Once a value for the hydraulic supply has been set, using the tip-trailer icons, it is saved. If the
unit or power supply is turned off, the value is still saved. It can be changed again, if desired, at
any time. To reset the value, activate the function and use the icons to reset it.
After setting the continuous-hydraulic-supply, it can be started by simply selecting its icon, as
shown below. The hydraulic supply will flow at the saved rate of flow.
There is no hydraulic flow sensor in the supply line to the tip trailer. Therefore, an external flow
sensor will be required if the hydraulic flow is to be measured.
To operate the hydraulic supply to the tip trailer use the functions listed below.
