Key:
A-B: dimensions used to determine where to fi t the post mounting bracket P
C: distance between mounts (recommended value: 993 mm)
X: distance from the gate centreline to the post edge
Z: distance between the post edge and the motor rotation centreline
α°: gate opening angle
P: post mounting bracket
D: gate section length
F: gate section mounting bracket

Fitting the post mounting bracket

• Defi ne the desired opening angle
• Measure the X dimension on the gate.
• Calculate B = Z + X given that Z = 110 mm
• From the table, choose A and B dimensions that are close to identical so as to match
the opening speed and ensure proper motor drive operation. If the chosen dimensions
are too far apart, gate section motion will not be constant and the push or pull torque
applied will vary during motion.
The table shows the optimum A and B values for an opening of α° = 90° at constant speed.
