What are automatic gate components?

Automatic gate systems offer convenience, security, and controlled access to a property. They consist of several key components that work together to automate the opening and closing of the gate. Here’s a breakdown of the essential parts:

1. The Gate Itself:

  • This is the physical barrier that controls access.
  • Types: Can be swing gates (single or double leaf), sliding gates (single or bi-parting, track or cantilever), bi-folding gates, or even vertical lift gates.
  • Materials: Common materials include wood, steel, wrought iron, and aluminium. The material and design affect the weight and wind resistance, which in turn influence the type of operator needed.

2. Gate Operator (Motor):

  • This is the “heart” of the system, responsible for physically moving the gate.
  • Types of Operators (depending on gate type):
    • Swing Gate Operators:
      • Articulated Arm Motors: Have a hinged arm that connects the motor to the gate. Suitable for gates with large pillars.
      • Ram (Linear Screw or Hydraulic) Motors: Use a straight arm that extends and retracts to push or pull the gate open/closed. Can be electromechanical (linear screw) or hydraulic.
      • Underground Gate Motors: Discreetly installed in foundation boxes beneath the gate, with only the motor arm visible.
    • Sliding Gate Operators: Use a motor with a cog that engages with a toothed rack attached to the gate, moving it along a track.

3. Control Board (Control Unit/Panel):

  • The “brain” of the automatic gate system.
  • Receives signals from access control devices and safety sensors.
  • Processes these signals and sends commands to the gate operator to open or close the gate.
  • Often includes programmable logic controllers (PLCs) for advanced functions and customization.

4. Power Supply:

  • Provides the necessary electricity to power the gate motor, control board, and other components.
  • Can be connected to the main electrical grid or powered by alternative sources like solar panels.
  • Battery Backup: Crucial for ensuring the gate can operate during power outages.

5. Access Control Systems:

  • Determine who can enter or exit the property.
  • Common types:
    • Remote Controls (Transmitters): Handheld devices to open/close the gate from a distance.
    • Keypads: Numeric keypads where users enter a PIN for access.
    • Intercom Systems: Allow visitors to communicate with occupants to request entry. Can be audio-only or video. For more about intercoms, read our Guide >>HERE<<
    • Card Readers: RFID or proximity card systems for secure access.
    • Vehicle Detection Systems (Loop Detectors, Photoelectric Sensors, Infrared Sensors): Detect vehicles approaching the gate and trigger opening automatically.
    • Smartphone Apps: Allow remote control of the gate via Wi-Fi or cellular networks.
    • Push Buttons/Switches: Manual controls, typically for exiting or for specific authorized personnel.

6. Safety Devices:

  • Crucial for preventing accidents and damage to vehicles or people. Always make sure you use DHF or GateSafe accredited contractors.
  • Photocells (Photoelectric Sensors): Installed in pairs on either side of the gate, they emit an infrared beam. If the beam is broken by an obstruction, the gate will stop or reverse.
  • Safety Edges (Pressure-Sensitive Strips): Installed on the leading edges of gates. When compressed, they signal the operator to stop and reverse.
  • Obstruction Sensors: Detect any obstacles in the path of the gate and prevent it from closing.
  • Flashing Lights: Alert users when the gate is in motion.

7. Emergency Release:

  • A manual mechanism that allows the gate to be opened in case of a power outage or system malfunction. This is a vital safety feature.

8. Accessories & Supporting Components:

  • Hinges or Latches: Essential for the proper operation and security of swing gates.
  • Tracks: For sliding gates, these are essential for the gate to move smoothly.
  • Limit Switches: Sensors that define the fully open and closed positions of the gate, telling the control board when to stop the motor.
  • Receivers: Devices that receive signals from remote controls.
  • Electric Locks: Provide additional security, ensuring the gate remains closed when not in use.

The specific combination of components will vary depending on the type of gate, its size and weight, the desired level of security, and the traffic volume.
