Which type of linear actuator swing gate operator extends and contracts the length of the actuator via hydraulic pressure?

• A. Hydraulic Piston
• B. Screw Drive
• C. In Ground Swing Gate Operator
• D. Belt and Pulley Drive

Answer: (A)

Hydraulic piston actuators use fluid pressure to move a piston inside a cylinder, creating linear extension and retraction. When hydraulic fluid is pumped into the cylinder, the piston pushes outward to extend the gate arm; releasing pressure or pulling fluid back lets it retract. This direct use of hydraulic pressure makes it a strong, smooth option for moving heavy gates and controlling the stroke precisely. Screw drive relies on rotating a threaded rod to move a nut along its length, converting rotary motion to linear but not through hydraulic pressure. Belt and pulley drive uses belts and pulleys to create linear motion, again without hydraulic fluid. In-ground swing gate operators refer to the installation style, not the actuation method, and can use different mechanisms, but the question specifically asks about hydraulic pressure, which is provided by the hydraulic piston.
