2.0 Actuators assembly to “K” plate Fig.4
ssemble the adjustable “K” plate and fix it to the wall. This operation is extremely important as it shall determine the following parameters:
1. Gate opening speed
2. Actuator thrust strength
Fundamental elements to make this choice are the following:
3. The gate size (weight/length)
4. Pillar size
You will find a series of sizes to determine the positioning of K plate with respect to the gate “V” rotation axis (hinge pivot). Fig.6-7-8
- F7 300mm STROKE ACTUATORS
- F8 400mm STROKE ACTUATORS
- For gates whose length is longer than cm 150, consider “B” measures higher than 10 cm.
- The “A” measure is actually ininfluent in the choice therefore it can be determined only by the size of the pillar.
- Some standard advised measures are (for 300 mm stroke actuators):
Gates not exceeding 150 cm: A=10 cm / B= 10 cm
Gates exceeding 150 cm: A= 14 cm / B= 12 cm
- Remind the higher is “B” measure, the slower the gate will open.
Caution: :maximum thrust strength allowed: 150 N
In order to be sure not to exceed 15 Kg of thrust strength, do not use measures shown in the blackened boxes of Fig. 7. In case it were necessary to use those measures, it is mandatory
to install a double pair of safety photocells. Fig.16 (Ref. 7012)
2.1 Front support assembly
After the “K” plate fixation, install the actuator through the pivot. ( Fig.1/a element F).
IMPORTANT: Then provide for the “STOPS” installation on the ground.
