== Automatic Barrier in gates == Aryaz97 (talk) 08:02, 18 September 2018 (UTC)Barriers are the equipment in busy places, which are mainly the entry routes of factories, large complexes, tolls and public parking lots. The overall division of the barriers is from two perspectives. The first method of operation and functionality and the second method of internal drive system. In terms of the type of operation, or in a better language, the shape of opening and blocking the path are divided into two types of barriers and columnar barriers.

Lever locks are the most common and also the cheapest type of barrier, and operate in such a way that a rig of approximately 1 meter height is installed vertically on the ground and a lever of varying lengths, for example, from two meters to eight Meters limit the traffic flow. A columnary barrier called Bullard is also identified. This kind of barrel is in the form of cylinders that fall into the ground and when they leave the ground they block the path, which are of course the most expensive type, but they are targeted by the environmental factors or architectures of each location. In terms of durability, they are considered the most unique type of barrier. The locomotives are divided into two types of electromechanical and electromechanical transmission lines for the type of propulsion system. Electromechanics have less traffic per hour than electro-hydraulic
