Install your own automatic sliding gate easily in just one weekend! If you are constructing your own gate please download the Gate Construction Guide and DIY Plans at: www.alldayfencing.com/adfshopdiy.php.
Sliding gates require a base for the track to sit on. The base can be constructed out of concrete. Excavate a footing for the concrete 200mm deep and 150mm wide. Lay some reinforcement steel in the trench and concrete to the level required. As concrete shrinks when it sets it is advisable to let the concrete set then bed you track down using a wet mix of sand and cement. Fix the track with concrete approval bolts.
The track must run for the full length of the gate plus the opening length. Sliding gates that are going to be automated should be 16″ (400mm) longer than the opening. This is to allow room for the motor.
When construction your gate frame you will need to recess two rollers at the bottom of the frame about 18″ (450mm) in from each end. Inch and a half (40mm) square steel section is advised for the frame with a 6″ x 1.5″ (140mm x 40mm) bottom rail to allow for the rollers and gear rack. If you intend to fix vertical wood pickets or panels than your frame will need a midrail. If you are fixing horizontal wood slats or boards, you will need vertical members in the frame at around 2′ (600mm) centers. To hold the top of the gate you will require a double roller and bracket setup as shown. Fix the roller bracket to the side fence post above the motor.

Several gate motor kits are available. Fix the motor to a concrete pad and position it so the gear wheel faces the gate. Screw the gear rack to the bottom rail of the gate so the gears interlock. Most auto gate systems come with self programming features which enable the motor to learn the start and stop points.
There is no need for a stop or lock a the electric gate motor will hold the gate firmly in position. Most systems are suitable for heavy and light gates up to 350kg and 4.5m wide without a lock or up to 6m with the use of a lock, the gates will slow down at the end of opening/closing operation avoiding loud noises and maximising durability, and, once the gate is closed it can’t be pushed open by intruders!
Most gate motors come with accessories such as movement sensors, external aerials, keypads etc. To view a common automatic sliding gate setup and wiring options view here: http://www.adfautomation.com.au/mhouseslidinggate.pdf
