The following table (C1) gives the recommended data for fixing the position of the operator mountings in relation to the center of rotation of
the gate leaf. The distances A and B will give:
-
The useful stroke length (C) of the piston
-
The peripheral speed of the gate leaf
-
The angle of maximum opening of the gate leaf
-
The holding capacity of the lock in relation to distance E (which must always be less than B when the operator is fitted with a hydraulic lock); the distance
E is obtained, in practice, by measuring the distance between the front attachment fulcrum to the gate hinge axis (see fig. C1)
•
The sum A+B corresponds to the useful stroke length of the piston (C) for a 90° opening of the gate leaf.
•
The minimum value of distances A and B is 70 mm, and the maximum is 130 and 140 mm respectively for operator type XT40,9
and 90 and 300 mm for type XT45.
•
If possible, distances and A and B must be equal, in order to have a uniform peripheral speed.
•
When A+B is greater than 270 mm, use operator type XT45; this avoids the necessity of having to cut insets in the posts.
•
If the gate leaf is to open by more than 90°, first of all find the best A and B measurements for mounting, and then reduce distance
B to the desired opening angle, making sure, by checking the distance Y, that the corner of the post doesn't interfere with the
operator action.
•
The greater the distance B in relation to E, the more efficient the holding capacity of the hydraulic lock (for all types of operator).
•
If the gate leaf is closed with an electric lock, then E must always be less than or equal to distance B (never greater).
