Why are photocells needed in the automatic system for sliding cantilever gates?

Why are photocells needed in automatic sliding cantilever gates? Photocells in automatic sliding cantilever gates are used as a core component of the safety system. Their purpose is to monitor the driveway and instantly respond to any obstacles in the path of the gate leaf. These obstacles can include cars, people, animals, or any objects that enter the danger zone while the gate is closing.

How photocells work

The system consists of two devices: an infrared beam transmitter and a receiver. They are installed opposite each other on both sides of the driveway. The operating principle is simple:

• as long as the beam between the elements is uninterrupted, the gate operates normally;
• if the beam is broken, the automatiс system receives a signal and either stops or reverses the gate.

This creates an invisible "control zone" that prevents accidents.

Benefits of using photocells

Photocells significantly increase the safety and convenience of operating automatic gates. They reduce the risk of vehicle damage and personal injury, while also protecting the gate mechanism itself from overload. Key benefits:

• preventing collisions between the gate and vehicles or people;
• protecting the electric drive and mechanical components from damage;
• increasing the overall safety level of the system;
• ensuring stable automation performance even under heavy use.

The economic benefit is also worth noting: installing photocells costs much less than repairing the drive or restoring damaged property.

Where installing photocells is especially critical

While photocells are recommended for all automatic gates, there are locations where their use is virtually mandatory:

• private properties with active traffic and children;
• industrial facilities and warehouses;
• parking lots and commercial properties with high traffic density;
• sites with limited visibility of the driveway area.

Photocells are not an optional accessory, but an essential safety feature for automatic sliding cantilever gate systems. They provide motion control, prevent accidents, protect people and equipment, and significantly improve the reliability of the entire automatic system.
