The electro-hydraulic B411/ B412/ B420 heavy duty barriers are suitable for vandal prone, unsupervised areas. These barriers have the performance required for high traffic sites.

Beam lengths are available up to 9 m as standard. Security options include: Lattice skirt, beam lights, warning xenon/ sounders, beam or raised 'apex' mounted traffic signs, pogo or fixed end supports.

A ‘Hi-Sec’ version (the B420 model), featuring full height anti-pedestrian skirts which are available in variable heights (1600, 1800 and 2000 mm), is also available. Multilayer protective coatings make these suitable for a wide range of commercial and industrial applications in the most demanding external environments. Programmable solid-state control combines simplicity, reliability and straightforward maintenance.

Features and benefits:

  • Powerful, electro-hydraulic design provides years of reliable service with minimum maintenance.
  • Durable cabinet design for high levels of vandal resistance in unsupervised locations.
  • Continuously rated, no limitations of number of operations per hour - can handle the highest throughput sites.
  • Available with side mounted arm and other configurations including bottom lattice, raised heavy goods vehicle (HGV) stop sign, safety edge, sounders.
  • A programmable solid state control unit provides total reliability and a complete choice of control; allavailable access control systems, local or remote push buttons, vehicle ID systems, remote transmitter units.

Applications:

Industrial, commercial and military applications including high usage sites.
