Field Hose Measurements for HRG Operators
Note: HRG operators are usually shipped without the hoses needed to complete the system.
HySecurity will make these hoses in custom lengths as required, attach the quick disconnect fittings and
pre-charge the hoses with hydraulic fluid. The use of pre-charged hoses is important to avoid the
introduction of air into the system.
When field measuring for the necessary hose length to order, the following may be helpful:
1. There is little room in the base of the HRG operator post 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 short, you will not reach the connections, if
your measurements are too long, you will have trouble finding space for the excess hose.
2. Remember that two hoses are needed for each cylinder. This means that you need four hoses 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.)
a. The bottom of the pump/control panel to the bottom of the trench, plus 24" (61cm)
b. The total distance across the trench.
c. The distance back up to the bottom of the operator, plus 6" (15cm)
d. The hose length inside the access panel. About 6 to 12" (15 to 30cm) is required for connections.
Check the HySecurity Price Book for the appropriate part number for the hoses.
The HRG 220 includes up to 5 0’ total length for the two hoses required.
The HRG 222 includes up to 150’ total length for the four hoses required.
