Hydraulic Rising Bollards’ Power Unit

Image
  Hydraulic rising bollards are one of the physical security systems that control the entry / exit of vehicles. Hydraulic bollards are generally produced with hydraulic, pneumatic, electromechanical, semi-automatic or manual triggers. In the mechanical body of the bollards, mostly stainless steel is prefering. In this article, information about the power units of hydraulic bollards will be given. For more information, visit Optima Engineering.             The power unit of the hydraulic rising bollards consists of two main elements: hydraulic part and electrical&electronics part. Hydraulic unit includes electric motor, directional valve, hydraulic valve and hydraulic oil. The electric motor in the hydraulic unit is generally AC (Alternating Current) motors. This electric motor is directly triggered by the contactor, which is the switching hyrdaulic cyclinder. This electric motor, which is started with a contactor, is also...

What   is   tyre killer types ? -They  are mostly preferred as mechanical tyre killer. The spikes/teeth work mechanically.   - Electro mechanically tyre killers are also available which moves the spikes/teeth work via link mechanism  connected with a gear box and  an AC Motor.   - Hydraulic Tyre Killers spikes/teeth raise help of a hydraulic piston. These tyre killers have separate hydraulic power units. The tyre killer and power unit  are  connected  between each of them with hydraulic hoses.   -Flush Mounted Tyre  K illers are installed in a concrete pit. Its main body and mechanism are underground but teeth/spikes are above of road surface.   For more information, visit Optima Engineering How is a  tyre killer mechanism ?   -Tyre killers often use  counter weight mechanisms  to allow the teeth raise again after a car pass on it, but preventing passage in the other direction.   -Some of manufactu...
