The main shaft of the gate operator is filled with hydraulic fluid, and there is a stopper in the center which separates the fluid into 2 chambers within the shaft. The stopper is connected to the part of the operator that moves in and out, opening and closing the gate. The motor is next to a pump with 2 tubes - one reaching into one chamber of fluid and another reaching into the other chamber of fluid. When activated, the pumps take water out of one chamber and pump it into the other chamber, which forces the stopper and likewise the gate operator to move in and out depending on whether the gate is opening or closing. Because of this simple design, hydraulic gate operators are much more reliable than electromechanical gate operators.
Gate opener can operate in extreme temperatures. From 14 degrees Fahrenheit to 140 degrees Fahrenheit (-10 C to + 60 C). Strong, compact hydraulic piston, available in various versions depending on specific needs and field of use. There are models featuring hydraulic locking and non-locking (reversible) models that need a solenoid lock to keep them in position. Operating force is adjusted with extreme precision by means of the control unit’s electronic control. Operation at the end of travel is adjusted electronically in the control panel.
