Swing Gates
Yes a manually operated Swing Gate can be automated so long as it is plumb, level and swings freely in both directions. The gate must move throughout its arc without binding in the hinges or dragging on the ground.
Note: gates over 100kg should have ball bearing hinges with grease fittings.
If the gate doesn't swing freely then the posts or hinges may need replacing. Grants Automation can do this for you. If you'd like to replace the posts or hinges yourself then see Swing Gate Hardware and Posts for Automatic Gates for more information.
The Gate Operator holds the gate firmly when closed but an electric lock is recommended for gates with a lot of flex wider than 2m or rigid framed gates wider than 3m. See Electric Locks for more information.
Sliding Gates
Yes an existing Sliding Gate can be automated so long as it is straight and slides freely throughout its entire length without any grabbing from the guides or track any where along the gate. The gate track must be in a straight line, any sudden dips or rises may prevent the gate operator from working properly. Repair or replace all worn or damaged gate hardware prior to installation.
Gate posts less than 150mm wide should be made from steel not timber. Replace posts where necessary. A freely moving gate will require less force to operate and will enhance the performance of the operator and give a long working life. The operator should be well drained and not be submersed in water or have water running past it in heavy rain.
If a guide post is used behind the gate it must have adequate clearance for rack, which is required by the gate operator.
