HRR Series Barrier
If there is a threat of vehicle attack in addition to the control of vehicle access in high security applications , hydraulic roadblockers are the unique solutios.Even
though the attack is from high tonnage vehicles with high speeds, it is not possible for the vehicle to keep on moving more than a few meters because of the damage given to the front, wheels and
the bottom of the vehicle. Drive is hydraulic, therefore in case of power failure roadblocker can be lowered or lifted manually with the help of foot / hand pumps and valves. Typical raise/lower
time is 3 seconds.With the help of microprocessor controlles electronics,raise/lower function can be achieved by every kind of card readers, biometric readers like fingerprint or hand shape , radio
control , on/of switch or keyswitch etc.
