Field Hose Measurements for
HVG and HRG Operators
When field measuring for the necessary hose length to order, the following may be helpful:
There is little room in the base of the HRG or the HVG operators and limited room in the
control/power panel, therefore, your field measurements must be very accurate when
calculating the length of the necessary hydraulic hoses. If your dimensions are too little, you
will not reach the connections, if your measurements are too long, you will have trouble
finding space for the excess hose.
Remember that two hoses are needed for each motor or each cylinder. This means that you
need four hoses when you are dealing with a HVG operator and also when you are installing a
HRG 222 (pair) operator.

Be sure to measure accurately the following distances: (the best way is to pull a cord through
the conduit, mark it, and then measure it.)
1. The bottom of the pump/control panel to the bottom of the trench.
2. The total distance across the trench.
3. The distance back up to the bottom of the operator.
4. Add approximately 6" for the hoses to reach up into the operator.
5. Add approximately 24" for the hoses to reach up into the power/control panel.
The part numbers for the hoses are:
1/4" hose for
HRG: H SFHO 004 SW
3/8" hose for
HVG: H SFHO 006 4216
