RIB K800 Mechanism - Dimensions

Selection of a sliding gate operator

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

The RIB K800 mechanism excels over the competition due to its ability to operate intensively. Even large residential complexes during peak hours are unlikely to experience more than 30 cycles per hour (this corresponds to approximately one vehicle every two minutes). Also, 300 cycles per day are enough that a sliding gate will hardly exceed them.

Finally, the 800kg gate covers most gate cases, as an average wrought iron gate weighs 50-60 kg/m. The point where special attention should be paid is that the gate should operate smoothly in manual mode. This means that we test the gate's movement without a mechanism or with the mechanism in manual operation. If the gate does not operate smoothly, it must be repaired. Otherwise, it will cause problems to the mechanism and malfunctions will occur.

Sliding gate - Checks before installing the mechanism

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

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

• If the rail is straight without bends, bumps, 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 rolling must be trouble-free.
• Shortly before the closed position of the gate, check the oscillation of the gate. If it moves strongly back and forth, intervention is required to repair the gate. Possible repair points are the gate's construction material (excessively flexible), the position of the rollers (they have a large gap with the gate), or the roller support point is quite flexible.
• The gate must enter smoothly into the receptacle at the closed position. It should "lock" so that it is not easy to lift with a crowbar.
• The open and closed positions of the gate must be defined by mechanical stops. In no case should the gate leaf be free to pass the closed or open position.

Typical sliding gate arrangement with mechanism

In the sketch above, we observe a typical arrangement of a sliding gate with a mechanism. Obviously, a basic element of the construction is the gate 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 touching only the wheels and rollers without significant oscillation.

The gate must have mechanical stops to define the closed and open positions. The mechanical stops define the travel of the gate.

The rollers are positioned in such a way that they maintain 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 hinder the gate's movement.

The gate rests on 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, 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 gate. The movement is transmitted to the gate by the motor's gear. The rack, which is a toothed bar, is mounted on the gate. The rack is the point of contact between the gate and the motor, and through it, the movement is transmitted.

Photocells are the most important accessory for a sliding gate with a mechanism. They prevent accidents and protect both users and their vehicles. They are installed at the gate opening and prevent the sliding gate from closing when there is an obstacle in its path.

Another accessory for a sliding gate (not shown in the sketch) is the warning light. It is placed in a prominent position to warn passing vehicles and pedestrians that the gate is in operation. It is a particularly useful device when the gate is adjacent to a busy road or when visibility is not the best possible.

Installation of RIB K800 sliding mechanism

The rack spacers usually allow fine adjustments of around 0.5cm. In case the gate is hollow at the height where the rack needs to be installed, without any 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 stagnates. 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 of the motor being hit by a passing vehicle.
• the base must be installed 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 photocells, a beacon, etc. are present, we define their position and then proceed with the cable routing. A detailed chapter on wiring will follow below. We simply state that it should be done by a professional electrician and in compliance with all safety rules.

When installing the base, we check that it is perfectly parallel to the gate. We also check with a spirit level that it is perfectly horizontal. The large hole in the base is for the cables to pass through. The base is installed with plugs (metal anchors) in the reinforced concrete.

Next, remove the mechanism cover. 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.

Point of caution: Before welding, disconnect the terminals from the control panel.

The metal rack consists of one-meter pieces. Each piece 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 figure above, there is the wide side of the spacer (shoulder) which is welded onto the gate. The main point of attention during the installation of the rack is the small gap that must exist between the gear and the rack.

This gap helps the gate operate correctly. If it is not there, the motor is forced to carry the gate, so eventually it will tire and develop a fault. If the gap is too large, the gear may "kick" and the gate's movement may not be correct. In both cases, there is a possibility of an issue with either the gate or the motor.

The correct gap is approximately 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 in contact with the gear. Then, after removing this surface, the motor will lower 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 to be followed.

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

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

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

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 mechanism's spring-loaded stem in one direction or the other. Particular attention is required so that the gate stops 2cm before the final position, both in the open and closed positions. In this way, the gate will not hit any fixed points at the end of its travel.
