Gate Automation: Drive Types and How to Choose

Automation turns a gate into part of the vehicle entrance: the leaf opens from a remote, from a phone, or by itself once a license plate is recognized. What follows is a reference guide rather than a sales pitch: how drives for sliding, swing, sectional and roller gates differ, which numbers they are sized by, which safety automation is mandatory, and what to ask a contractor in advance. SAT Solutions neither fits nor services gate automation — this material is written for people choosing a solution on their own.

The site dictates the gate type, not the catalog. A sliding gate needs a straight run along the fence roughly one and a half times the opening width — in exchange, you can park in front of it and a snowdrift by the leaf does not matter. Swing gates are cheaper and simpler, but they need clearance to open inward or outward and cope worse with wind. Sectional doors fold up under the garage ceiling, freeing space both in front of the opening and inside. Roller gates coil into a compact box and save the day where there is neither ceiling for tracks nor room along the fence.

A drive is sized by numbers, not by eye. For sliding gates you count the leaf mass and the travel distance, adding the gear rack and support rollers: typical residential series are rated for 500–800 kg, mid-range ones for 1000–1200 kg, and heavier leaves move into the industrial class. For swing gates the deciding factors are leaf length and how much it catches the wind: a solid panel wider than two meters creates a wind load that an entry-level linear drive cannot handle, so an articulated arm or an underground drive with more torque is needed. Sectional doors are sized by panel area and lift height, roller gates by mass and shaft diameter.

Safety is a mandatory part of the kit, not an accessory. Photocells across the opening stop the leaf and send it back when a car drives in or a person walks through; a flashing lamp warns of movement and matters most where the gate opens onto a sidewalk. Force adjustment and obstacle reversal protect against crushing, and limit switches fix the end positions. A mechanical lock or key release is needed for power outages: it must be possible to open the gate by hand without dismantling the drive. One more element is the mechanical stop that keeps a sliding leaf from running off its rail.

Duty cycle separates a residential drive from a commercial one more sharply than raw power does. Home series are rated for a few dozen cycles a day and have a limited working period: after a run of operations the motor needs to rest, or thermal protection cuts in. The entrance of a housing estate, a warehouse or a plant means hundreds and thousands of cycles, and that calls for intensive-duty series with forced cooling and a gearbox built for continuous work. A margin is also needed for climate: in frost the grease thickens, the guides ice up and starting torque grows, while in summer sun the motor overheats. A drive sized to the exact minimum fails precisely in heat and frost — that is, exactly when you most need to drive in.

Control modes follow the scenario. Remotes and fobs are the minimum; a guard's button belongs where there is a manned post; a GSM module opens the gate with an ordinary phone call and no subscription fee; a smartphone app is convenient when access has to be granted and revoked. Gates are linked to an intercom so the entrance can be opened from the apartment, and to license plate recognition when vehicles should enter without stopping. Five things are worth asking a contractor: what leaf mass and duty cycle the drive is rated for, whether photocells and a lamp are included in the kit, how the gate opens without electricity, what ingress protection rating the housing and control board carry, and whether spare boards and remotes for that series are in stock.

How we help. SAT Solutions supplies gate automation equipment and helps size the drive to the leaf: the catalog carries the ZKTeco ZK-SW300DC swing-gate automation kit at 6,186,900 UZS, the ZKTeco ZK-SW400DC drive at 5,939,900 UZS and the Tuya PST-WD400A Wi-Fi module for garage doors at 231,900 UZS; catalog prices change, so the product page is always the current source. If the task is wider than the gate itself — organizing entry to a site, letting your own vehicles through without stopping, keeping a log of arrivals — that is our own field: barriers, license plate recognition and access control, in the Barriers & automation section (/solutions/barrier).
