About barriers and not only … The dictionary Dahl appears: BARRIERS – German. standpipe timber which is locked passage; zheravets, ochep, overweight, outpost. For many years the barrier has changed little, but still suffered a serious modernization. The barrier of the 21st century – a mechanical device operated manually or fully automatic unit, controlled by buttons or by remote control. The 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 a hydraulic or electromechanical.
Electromechanical barriers. Advantages: simple design, low cost, high maintainability. Disadvantages: slightly more than less than hydraulics life. Some manufacturers: CAME, NICE, DITEC. Hydraulic barriers. Advantages: reduced friction in the construction of the barrier to mechanical parts. They have been replaced by a hydraulic drive, which leads to some increase in service life.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. Features barriers. Managing barrier may be accomplished by remote keyfob transmitter (the remote control to the barrier) transmitting the encoded digital signal, or by means of such control devices as the key-switch, magnetic card, push button or position of a single button control operating mode (open – stop – close), which facilitates the operation of the barrier. The equipment can be equipped with safety devices – solar cells that block the work of the barrier, while in their area vehicle or person, as well as the warning light (flashing light) blinks during the boom. The barrier is equipped with an unlock when power is off, the barrier can be placed in manual mode. 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 tinning barriers showed that the fault in the automatic barriers arise, as a rule, not as a result of time between failures, and as a result of some external mechanical damage. In this regard, we Electromechanical barrier to stop, repair period not exceeding five days and repair costs are much lower than that of hydraulic barriers. Design, reliability and cost barriers CAME, NICE, DITEC about the same, but the parts are always available from stock holding only representatives of the company CAME. Our choice. It is noteworthy that the ratio of “price – quality – maintainability ‘, we stopped at the barrier CAME, since the logic of this equipment is extremely simple, regularly supplied parts, remote control of all upgrades are compatible with each other, the demands to the supply voltage 15%, which is close to the domestic state standard of 20%.
