The opening mode depends, as we have already noted, on the available space, the car size and the possibility on the floor and on the roof of the garage to install the accessories required by each of these automatic doors.

How to install an automatic door: the motor


Without a doubt, the engine is the soul of a portal automation. Before we talk about the step by step installation of an automatic door, let’s take a look at the types of motors available in the market.

Industrial roller

As the name suggests, this type of engine is suitable for large doors. They have been designed for opening doors of over 20 square meters, which incorporate gear bars.

The industrial roller motor has a microprocessor that allows it to be operated with a remote control. Too support the use of sensors, detectors and even barriers.

Rotation motor

Used on swing doors, of course. Its main feature is that its operation is hydraulic. They are quiet motors, with an elegant appearance and can be operated manually as well as remotely.

Motors to be used in doors of the same system: swinging arm. It is a motor that adapts very easily to any type of door, so it can be used in small businesses.

Sliding motor

Sliding gates require a sliding motor. For its installation the use of zippers along the entire length of the door.

How to install an automatic door step by step


Before moving on to the step-by-step description of a typical engine installation for Automatic doorLet’s see the tools we will need:

  • Fixed key
  • Drill
  • level
  • Small flat screwdriver.

Now let’s take a step by step of a typical installation of a automatic sliding door:

Let’s start by establishing an electrical pre-installation. This is essential to obtain the the energy the system needs. Next, we place the cables: We will find two 4 x 0.25 mm squares (they go to the sides) and one 3 x 1.5 mm square which is the one that receives the electrical energy.

We continue with the installation of the base, at a door safety distance, which can be 4 to 5 cm. We need to fix the base very firmly, for which we will use a drill, with bits of at least 10 mm.

Let’s continue by introducing the cables that we placed in the first step, through a hole that the base has in its lower part, as well as through the base that the motor must fix to the metal base.

Before mounting the rack, the motor must be unlocked. To do this, we insert the key in a lock provided for this purpose at the front of the engine, we turn it and the window will open

At this time of installation, the door must be closed. If so, we can now place a first piece of the rack at the end of the portal.

Making sure it’s level is very easy using the level we had from the start. A space of about two millimeters is left between the rack and the pinion.

Once we have placed the zipper, we must check that the gate opens and closes easily, without any difficulty. Another important point is to make sure that at the end of the spring it does not come into contact with the rack. If this is the case, it is very likely that the gate will stop anywhere on the route.

Now we can put the final anchoring of the engine. We install the limit switches at both ends, so that when the gate reaches one of them, the system is activated and the electric current is cut off, causing the motor to stop.

We lock the engine again, close the window by turning the key and the installation will be completed.
