Active Bollards

Active Bollard:-

ESSI Hydraulic Bollards crash Rated for A-40KN,B- 180KN,C- 350KN.Bollard System is equipped with Integrated Electro Hydraulic Drive Unit that can operate Single or Multiple bollards in various combinations. ( It is possible to have One Drive unit to operate 3 Bollards in each Road Lane for Up to SIX lanes).
The Hydraulic Fluid recommended to be used is Bio Degradable

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-
•  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
•  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.
