Drives for garage doors

Rail drives for sectional doors. We match the power to the area of the leaf and to how many times a day the door runs.

The parameters shown with the models come from the manufacturer data sheets and are indicative. We pick the right drive once the leaf weight, the dimensions and the expected number of cycles are known.

Overview

Every model by parameter

The list above is arranged by brand. Here the brand takes second place - the most powerful drives are at the top. A dash marks a parameter the manufacturer does not give for that model.

Selection

Four things that decide

  • Power matched to leaf weight

    A drive working at the limit of its capacity is noisy and wears out faster. A margin of power costs little and extends the life of the whole set.

  • Chain or belt

    A belt runs more quietly and suits a garage under a bedroom. A chain is cheaper and less sensitive to heavy loads.

  • Obstacle detection

    The drive stops and reverses the door when it meets resistance. That is a requirement, not an extra - in domestic doors too.

  • Emergency opening

    In a power cut the door is released by hand. If the garage has no second entrance, a battery is worth considering.

Not sure which drive to pick?

Tell us the size of the door and the expected number of openings a day. We will point to a model with the right margin of power.

Garage door drives - rail, belt or chain

In a garage attached to a house you hear the drive every day. So beyond power, what counts is how the motor transmits movement to the leaf.

A rail drive is a motor fixed under the ceiling and a rail along which a carriage pulls the door leaf. Transmission is by toothed belt or by chain. A belt runs more quietly, needs no lubrication and is the natural choice for garages adjoining the living space or sitting under a bedroom. A chain is cheaper, louder and less sensitive to heavy loads - it copes well with heavier leaves and detached garages.

Pulling force is matched to the area and weight of the leaf. Manufacturers give it in newtons, but the figure alone says little without the size of the door: the same 600 N is enough for a 2.5 by 2 metre door and too little for one twice that size. Then come the rail length, matched to the height of the opening, and the number of remotes in the set - a four-channel remote handles the door, the gate and the driveway lights, and adding one later means programming all over again.

A garage drive should have obstacle detection and a manual release. The first stops and reverses the door when it meets resistance - required by the standards, in domestic doors too. The second lets you open the door by hand in a power cut. If the garage has no second entrance, a backup battery is worth considering: releasing the door from outside is awkward, and the car stays shut inside.

What to check before buying

Room under the ceiling
The drive rail needs clear space above the door tracks. Services there call for a different solution.
What is above the garage
A room above the garage argues for a belt. A chain on a detached building bothers nobody.
A margin of pulling force
A drive at the limit of its capacity is noisy and wears out faster. The margin costs little.
A second way to open it
A code keypad or key switch works when the remote runs flat or stays in the other car.
