RIB K800 Mechanism - Dimensions

Choosing a sliding gate operator

• The weight of the sliding gate. The RIB K800 mechanism is suitable for a gate weighing up to 800kg.
• The frequency of gate use per day. The RIB K800 mechanism is suitable for up to 300 opening/closing cycles per day.
• The frequency of gate use per hour. The RIB K800 mechanism is suitable for up to 30 opening/closing cycles per hour.

The RIB K800 mechanism has an advantage over the competition due to its ability to operate intensively. Even large residential complexes during peak hours are unlikely to have more than 30 openings/closings per hour. (this corresponds to approximately one vehicle every two minutes). Also, 300 openings/closings per day are sufficient, so a sliding garage door is unlikely to exceed them.

Finally, the 800kg gate covers most gate cases, as an average fence gate weighs 50-60 kg/m. The point that requires particular attention is that the gate should operate smoothly in manual mode. This means testing the gate's movement without a mechanism or with the mechanism in manual operation. If the gate does not operate smoothly, it should be repaired. Otherwise, it will cause problems to the mechanism and lead to malfunctions. 

Sliding garage door - Checks before installing the mechanism

The most basic check that needs to be done even before ordering the mechanism is to check if the gate operates smoothly by hand. Open and close the gate at a steady speed, approximately the same as it would with the mechanism. If the movement is difficult at some point, there is a jolt, etc., the gate should be repaired before installing the mechanism.

The checks that need to be carried out in detail are:

• If the rail is straight without curves, dents, or rust. It must also be properly secured to the ground.
• The gate wheels must be in good condition. They should not show signs of deformation or rust. Their movement must be trouble-free.
• Just before the gate's closed position, check the gate's oscillation. If it moves excessively back and forth, intervention is required to repair the gate. Possible repair points include the gate's construction material (too flexible), the position where the rollers are installed (they have a large gap with the gate), or the rollers' support point is too flexible.
• The gate must enter smoothly into the receptacle at the closed position. It should "lock" so that it is not easy to lift it with a lever.
• The open and closed positions of the gate must be defined by mechanical stops. Under no circumstances should the gate leaf be free to pass the closed or open position.

Typical layout of a sliding garage door with an operator

In the sketch above, we observe a typical layout of a sliding garage door with an operator. Obviously, a basic element of the construction is the gate leaf, which can be made of aluminum, metal, or wood. The basic prerequisite is that it must be robust and sufficiently rigid so that it can move, while only resting on the wheels and rollers, without excessive 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 as to be in contact with the gate leaf throughout its entire travel (from the fully open to the fully closed position). Essentially, the rollers keep the gate perpendicular to the ground. A basic prerequisite is that they do not impede the gate's movement.

The gate rests on the wheels which allow it to move. The movement takes place on the rail which is shaped to work perfectly 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, straight, and without bumps or deformations.

The motor is also positioned so that it is always in contact with the door. The motion is transmitted to the door by the motor's gear. The rack, which is a toothed bar, is attached to the door. The rack is the point of contact between the door and the motor, and through it, the motion is transmitted. 

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

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

Installation of RIB K800 sliding mechanism

The rack spacers usually allow for minor adjustments of around 0.5cm. If the gate is hollow at the height where the rack needs to be installed, with no support point, we have two options: either reinforce the gate 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 gate leaf should be approximately 40cm longer than the opening so that the motor can be installed outside the opening. Otherwise, there is a risk that the motor will be hit by a passing vehicle.
• the base must be installed on a stable foundation. If there is no such thing (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 route the wiring. A detailed chapter on wiring will follow below. We simply mention that it should be done by a professional electrician and with adherence to all safety regulations.

When installing the base, ensure it is perfectly parallel to the door. Also, use a spirit level to check that it is perfectly horizontal. The large hole in the base is for routing cables. The base is installed with plugs (metal anchors) into the reinforced concrete.

Next, remove the cover of the mechanism. To remove it, unscrew the corresponding screws. Secure the mechanism to the two screws protruding from the base. Place it on the base and tighten the screws.

To operate the mechanism manually, lift the flap, insert the key into the lock, and turn it counter-clockwise 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: Before welding, disconnect the terminals from the control panel.

The metal rack consists of one-meter sections. Each section has three oval-shaped holes where the spacers are placed. 

It is advisable to screw the spacers in the middle of the holes so that micro-adjustments can be made later if necessary. As shown in the diagram above, there is a wide side of the spacer (shoulder) which is welded to 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 the door to function properly. If it is not there, the motor is forced to carry the door, so it will inevitably get tired and break down at some point. 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 with the motor. 

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

During the installation of the rack, we must not weld the rack pieces together and we 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.

Also, care must be taken to ensure that the gear engages with the rack throughout its entire travel. If necessary, we can loosen the mechanism's mounting and move it perpendicular to the door leaf to achieve the correct position. 

The necessary check for correct rack installation 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 motor mounting screws.

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

Next, the terminals, which are included in the mechanism kit, 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 rod of the mechanism in one direction or the other. Particular attention is required to ensure that the door stops 2cm before the final position in both the open and closed positions. This way, the door will not hit any of the fixed points at the end of its travel.
