Stopping the Gate
All models employ a time delay Soft Stop system.
Additionally, brake valves (shown at right) are used to control
the smooth stopping of the gate. These valves are exclusive
to Hy-Security’s operators. They are independently adjustable
to allow the gate to stop predictably without banging.
Starting the Gate
When starting very heavy barrier arms, it is necessary to Soft
Start the load gently, in addition to stopping it smoothly. Hy-
Security accomplishes Soft Start with another exclusive
feature we call an AWOG, which diverts some of the start-up
hydraulic flow and thereby allows the gate to gently
accelerate. This is much like letting your foot slowly off a car
clutch – no lurching when the gate starts. The AWOG
improves the life and performance of a gate system and never
needs adjustment.
NOTE: This feature is standard on the HTG 320-8 only.
