The mechanics behind automatic gates
Automatic gates are a convenient and efficient way to control access to a property. These gates use various mechanisms to open and close, providing security and convenience to homeowners and businesses. Understanding the mechanics behind automatic gates can help users make informed decisions about their installation and maintenance.
There are different types of automatic gates available, but most of them operate on similar principles. They typically consist of a gate leaf or door that is attached to a motorized mechanism. This mechanism can be hydraulic, electromechanical, or electro-hydraulic, depending on the specific gate.
In hydraulic systems, a hydraulic pump is used to generate pressure that moves the gate. This pump is typically powered by an electric motor. When the gate needs to open or close, the motor activates the pump, which pressurizes the hydraulic fluid. The pressurized fluid then moves a piston or cylinder, which in turn, moves the gate. By controlling the direction and flow of the fluid, the gate can be opened or closed smoothly and accurately.
Electromechanical systems, on the other hand, use an electric motor to directly move the gate. The motor is connected to a gearbox that converts the rotational motion into linear motion. This linear motion is then used to operate the gate. Electromechanical systems are commonly used for lighter gates, as they are generally more compact and cost-effective compared to hydraulic systems.
