Drive to the sliding gate

[Vermes]

All the elements of the fence were heated up in a heating stove and bended in a garage on benders and own made templates. It took about a year of work.
Things needed to the drive:

• racks
• controller “Bramster”

The intention was to build an engine of 12V tension. Because of the fence weight (400kg), the engine should be strong. An engine with support from Opel Corsa was used. It had to be transformed a little, the whole steering column was cut off. The axle repulse was made on that side. The socket for the bearing was made by a turner. It was welded centrally to the seat made of plate, which was left from the cut off column.
When the whole mechanism was ready, the housing and engine mount could be made. Then it's time to make an opening time test. The result was positive and 15s time was quite satisfying.
The next problem was the controlling. Firstly, the power supply was to be placed in the garage, and only 12V was to be led to the engine. The 2,5mm wire occurred not to be proper, because of the huge drop of tension (50%). Everything had to be placed in the box close to the gate. The lack of tension is solved by reels in the left side bottom. With a screw, it can be tilted left and everything falls, causing the sliding gear rack. Then the gate is moved manually. An UPS would be needed with an accumulator to reach a bigger capacity.
The opening and closing is protected by limit switches. A thermal protection should also be made in order to avoid engine damage.
The infrared barrier is placed on bars. That would prevent the gate from squeezing anyone who comes there by an accident.
The gate opens and closes properly. It's used from several months, often few times a day. It is also resistant to frost -24 Celsius degrees.
