1.1 - Basic Hinge Geometry
Before beginning your installation of your KRONO system, check the following:
• Your gate piers or posts are sufficiently strong enough to support the gates and operators and the
gates swing freely and there is no friction between the moving parts.
• Measurement C must not be greater than the value shown below. If this is the case, it is necessary
to modify the pillar so that this measurement corresponds.
Dimension C must be no greater than 60mm for 90° opening and no greater than 50mm for a 120°
opening.
• Ensure that a centre stop is securely cemented into the ground. As a guide ensure that the centre
stop protrudes no more than 65mm. Any higher and it might catch the underside of a car.
