Electromechanical Barriers

About barriers and not only The dictionary Dahl appears: barriers – German. standpipe timber which is locked fare; , ochep, preponderance outpost. For many years the barrier has changed little, but still suffered a serious modernization. Barrier of 21 century – is a mechanical device operated manually or fully automatic assembly, controlled by buttons or by remote control. The design of an automatic barrier is simple. He consists of a rack placed inside a gear motor and control unit, as well as arrows. Depending on the actuator arm, automatic barrier may be hydraulic or electromechanical. Electromechanical barriers. Advantages: simple design, low cost and high maintainability. Disadvantages: slightly more than smaller compared with the hydraulics life. Some manufacturers: came, nice, ditec. Hydraulic barriers. Advantages: reduced in the construction of the barrier rubbing mechanical parts.

They are replaced by a hydraulic drive, which leads to some increase in service life. Disadvantages: Very low maintainability (if Fault is useful to replace the compressor and the hydraulic cylinders). Some manufacturers: faac. Opportunities barriers. Managing barrier may be implemented by remote keyfob transmitter (the remote control to the barrier) transmitting the encoded digital signal, or such control devices as a key-switch, magnetic card, push-post, or a single button control operating mode (open – stop – close), which facilitates the operation of the barrier. Equipment can be supplied with safety device – solar cells that block the work of the barrier, while in their zone vehicle or person, as well as indicator light (beacon), the flashing arrows on the move. Equipped with a barrier and unlock when power is off, the barrier can be switched to manual control. The electronic control board allows for features such as automatic closure of the barrier, the synchronization of the barrier, slowing down arrows at the bottom of the loop opening – closing. ! Personal experience. Our experience company barriers showed that the fault in the automatic barriers arise, as a rule, not the result of mtbf, as a result of some external mechanical damage. In this regard, we stopped on the Electromechanical barrier, repair period not exceeding five days, while the cost of repairs to the order of magnitude lower than that of hydraulic barriers. Design, reliability and cost barriers came, nice, ditec about identical, but the parts are always available from stock held only by the representatives of the firm came. ! Our choice. It is noteworthy that the ratio “price – quality – maintainability ‘we stopped at the barrier came, since logic this equipment is extremely simple, regularly supplied parts, remote all upgrades are compatible with each other, the requirements to the supply voltage 15%, which is close to the domestic state standard of 20%.
