Road Blocker

Road Blockers:-


ESSI Road Blocker offers maximum security for highly sensitive, entry-exit point against unauthorized vehicles of all sizes and weights. Crash tests carried out under the supervision of the TV (Technical Inspection Agency) with an impact of a 7.5 ton truck traveling at 80 km/h certify the high reliability of the Road Blocker , heavy duty vehicles at highSpeed is also reliably stopped.

The Road Blockers "DSP" are designed to remain fully operational after the impact and consequently continue to guarantee the full level of security.


Key Features:


•  Compact hydraulic unit with motor, pump, solenoid valve and high pressure hydraulic cylinder.

•  Red flashing light in blocking element.

•  Emergency operation during power failure using hand pump.

•  Control in separate control box.

•  Blocking height: A-650mm/ B-800mm
•  Available impact/Cash strengths:  DSP1-450kN, DSP2-600kN, DSP3-900kN, DSP4-1250kN and DSP5-
   2500kN
•  Can be standard/ automatic control/ fully automatic operational with central command and control for
   multiple units- with video feeds/ 2-way voice communication and central operation control with data
   logging.
•  Long term corrosion protection through galvanizing and 3 layers of bonded plastic 4S.
•  DRDO- CCE (R&D) and Certified for confirming compliance with stated impact strength/ crash rating and
   equivalence to  ASTM f 2656 -07 / UK PAS / DOS K ratings.


Technology Used:


The Road Blocker is operated by high speed hydraulic cylinders. A power pack containing an electric motor – pump assembly and an accumulator/handle for manual operation (in case of power failure) is installed up to a distance of 20 meters from the barrier in all weatherproof lockable steel casing on a concrete Base. The operation time for moving the blocker up & down can be from 2 to 6 seconds. When activated, the extremely heavy blocking segment will extend and block the entry. The average blocking height is 650 mm. With a dynamic road blocker, the barrier is "lifted" and can therefore reach a blocking height of 850 mm. Due to the  eye-catching warning color and the warning lights the blocking segment is clearly visible to approaching vehicles which allows the vehicles to stop in good time. In the lowered position the Road Blocker is absolutely unobtrusive and flush with the road surface.
