RIB K1400 Mechanism - Dimensions

Selecting a sliding garage door mechanism

• The weight of the sliding garage door. The RIB K1400 mechanism is suitable for doors weighing up to 1400kg.
• The frequency of door use per day. The RIB K1400 mechanism is suitable for up to 400 openings/closings per day.
• The frequency of door use per hour. The RIB K1400 mechanism is suitable for up to 50 openings/closings per hour.

The RIB K1400 mechanism excels over the competition due to its ability to operate intensively. Even large residential complexes during peak hours rarely experience more than 50 openings/closings per hour (this corresponds to approximately one vehicle every two minutes). Also, 400 openings/closings per day are sufficient so that a sliding garage door is unlikely to exceed them even in a commercial setting.

Finally, the 1400kg door capacity covers most door cases, as an average metal gate weighs 50-60 kg/m. The point where particular attention should be paid is that the door must operate smoothly in manual mode. This means testing the door's rolling without a mechanism or with the mechanism in manual operation. If the door does not operate smoothly, it must be repaired. Otherwise, it will cause problems to the mechanism and lead to malfunctions. 

Sliding garage door - Checks before mechanism installation

The most important check to be made even before ordering the mechanism is to ensure that the door operates smoothly by hand. We open and close the door at a constant speed, roughly the same as it would have with the mechanism. If at any point the movement presents difficulty, there is a jolt, etc., the door must be repaired before the mechanism is installed.

The checks that must be carried out in detail are:

• If the rail is straight without curves, dents, and rust. It must also be properly secured to the ground.
• The door rollers must be in good condition. They must not show signs of deformation or rust. Their rolling must be problem-free.
• Just before the closed position of the door, we check the door's oscillation. If it moves intensely back and forth, we must intervene and repair the door. Possible repair points are the door's construction material (excessively flexible), the position where the rollers are placed (they have a large gap with the door), or the roller support point is quite flexible.
• The door must enter smoothly into the receptacle at the closed position. It must "lock" so that it is not easy to lift with a crowbar.
• The open and closed positions of the door must be defined by mechanical stops. In no case should the door leaf be free to pass the closed or open position.

Typical sliding garage door arrangement with mechanism

 In the sketch above, we observe a typical arrangement of a sliding garage door with a mechanism. Obviously, a key element of the construction is the door leaf, which can be made of aluminum, metal, or wood. A basic prerequisite is that it must be sturdy and rigid enough to be able to move, while only touching the rollers and guides, without significant oscillation.

The door must have mechanical stops to define the closed and open positions. The mechanical stops define the door's travel. 

The rollers are placed at such a point that they are in contact with the door leaf throughout its entire travel (from the fully open to the fully closed position). Essentially, the rollers keep the door perpendicular to the ground. A basic prerequisite is that they must not hinder the door's movement.

The door rests on the wheels which allow it to move. The movement takes place on the rail, which has a shape that allows it to perfectly cooperate with the wheels. The wheels must be in good condition without signs of deformation or rust. The rail must be properly supported on the ground, be straight and not show any bumps or deformations.

The motor is also placed at a point where it is always in contact with the door. The movement is transmitted to the door by the motor's gear. The rack, which is a toothed bar, is placed on the door. The rack is the point of contact between the door and the motor and through which the movement is transmitted. 

Photocells are the most important accessory of a motorized sliding garage door. They prevent accidents and protect both users and their vehicles. They are installed at the door opening and prevent the sliding door from closing when there is an obstacle in its path. 

Another accessory for a sliding garage door (not shown in the diagram) is the warning light. It is placed in a conspicuous position to warn passing vehicles and pedestrians that the garage door is in operation. This is a particularly useful device when the garage door is adjacent to a busy road or when visibility is not optimal. 

Installation of RIB K1400 sliding mechanism

The rack spacers typically allow for minor adjustments of around 0.5cm. If, at the height where the rack needs to be installed, the door is empty without any support point, we have two options: either reinforce the door at that point or change the installation height of the mechanism (with a base) to reach the point where the rack can be installed.

In addition to the above limits for the installation of the mechanism, we must take into account that:

• it should not be installed in an area where water accumulates. If there is such a suspicion, a base should be created so that the motor is higher.
• the door leaf should be approximately 40cm larger than the opening so that the motor can be installed outside the opening. Otherwise, there is a risk of the motor being hit by a passing vehicle.
• the base must be placed on a stable foundation. If there is no such foundation (e.g., a reinforced concrete slab), a concrete base must be created.

Next, we define the position of the accessories. If there are photocells, a flashing light, etc., we define their position and then proceed with the wiring. There will be a detailed chapter below on wiring. We simply mention that it should be done by a professional electrician and with adherence to all safety rules.

When installing the base, we check that it is perfectly parallel to the door. We also check with a spirit level that it is perfectly horizontal. The large hole in the base is for the passage of cables. The base is installed with plugs (metal wall plugs) into the reinforced concrete.

Then we remove the cover of the mechanism. To remove it, we unscrew the corresponding screws. We secure the mechanism to the two screws protruding from the base. We place it on the base and tighten the screws.

To operate the mechanism manually, lift the small door, insert the key into the lock, and turn it counterclockwise as many turns as needed until the key stops. In this position, the motor has been disengaged, and we leave it in this state until the rack installation is complete.

Important note: Before welding, disconnect the terminals from the control panel.

 The metal rack consists of one-meter pieces. Each piece has three oval holes in which the spacers are placed. 

It is good practice to screw the spacers in the middle of the holes so that there is potential for fine adjustments later if needed. As shown in the diagram above, there is a wide side of the spacer (shoulder) which is welded onto the door. The main point of attention during rack installation is the small gap that must exist between the gear and the rack. 

 This gap helps in the proper operation of the door. If it is not present, the motor is forced to carry the door, and at some point, it will inevitably break down. If the gap is too large, the gear may "kick" and the door's movement may not be correct. In both cases, it is likely to cause a problem either with the door or the motor. 

 The correct gap is around 1.5 mm. To achieve this, we can place the mechanism on a surface of this thickness and proceed with the installation of the rack with contact to the gear. Then, after removing this surface, the motor will move down by 1.5mm, so we will have the necessary gap.

During the installation of the rack, we must not weld the pieces of the rack together and must maintain its pitch. Also, the rack must not be welded to the spacers. The following diagram shows exactly the procedure that must be followed.

We must also ensure that the gear meshes with the rack throughout its entire travel. If necessary, we can loosen the mechanism's support and move it perpendicular to the door leaf to achieve the correct position. 

The necessary check for the correct installation of the rack is performed by opening and closing the door at a constant speed. If the door moves smoothly without jolts, noises, etc., then the rack installation is correct. Then we can tighten the screws of the spacers as well as the mounting screws of the motor.

Important note: Before operating the mechanism electrically, we must first confirm the opening direction (it must be correct) and install the limit switches.

Next, the terminals included in the mechanism set are installed. Under no circumstances should makeshift terminals be used or their shape modified, as this will cause the mechanism to malfunction. The terminals are positioned to activate the mechanism's limit switches. This is done by pushing the spring-loaded plunger of the mechanism in one direction or the other. Particular attention is required to ensure that the door stops 2cm before its final position, both in the open and closed positions. In this way, the door will not hit any fixed points at the end of its travel.
