‘Hi-sec’—High Security Barriers

Based on the tremendously successful Series 410 design, the Series 420 has the added benefit of very strong, full height antipedestrian skirts both above and below the arm.

The side mounted arm allows the skirts to be fitted along the full length without any gaps, giving it the speed of operation of a barrier with the strength and security approaching that of a gate.

The Series 420 shares the same reliable hydro-electric operation and multi-layer protective coating as the Series 410 making it ideal for high-vandal, unsupervised applications and has the performance required for the highest usage industrial, commercial or military sites.

Full height, ‘double lattice’ aluminium construction skirt for high security applications. Powerful, electro-hydraulic design for years of trouble free service. Continuously rated, no limitations on number of operations per hour—can handle the highest throughput site. Reliability proven in high usage industrial, commercial and military sites over long periods with minimum maintenance.

Available in a wide range of operating voltages. Side mounted arm allows full height skirt along the entire length of the arm without gaps. Programmable solid state control unit provides total reliability and a complete choice of control; all available access control systems, local or remote pushbuttons, vehicle ID systems, remote transmitter units etc. Immensely strong cabinet for high vandal resistance in unsupervised locations.




10mm base plate takes 6 widely spaced fixings for security of mounting.


High grade aluminium arms of 3mm wall thickness; 100mm dia section up to 6m length.

Instantaneous reversal of arm movement anywhere in travel.

Side mounting arm is counter balanced for ease of manual operation in the event of power failure.

Arm pivots on massive continuous-line-duty bearings.

Heavy duty skirt to 1.9m above road level (standard kerb).

Operating speed adjusted to suit arm type and local conditions, rises full 90 degrees in 4 to 6 seconds.

Skirt entirely of aluminium construction with double lattice (i.e. lattice on both sides of the arm) for immense strength.



♦ ♦ ♦

Heavy duty motor, separate pump and continuously rated solenoids give high reliability under both very high and very low use.

Hydraulic damping and ‘final lowering’ provides smooth, controlled operation.

Modular, programmable, solid state, plug-in control unit in IP55 enclosure; easily changed for maintenance. Built-in cumulative counting facility.


Continuously welded casing of 10mm and 3mm mild steel provides immense strength and security.

Top and rear covers are readily removable by key providing easy access for maintenance personnel.

All available access etc, systems accommodated using plug-in programmer to change factory-set defaults for delays, time out, etc.

Standard operating range; -10 to +45 degrees centigrade.

High quality powder coating finishes, minimum 75 microns DFT over ‘kephos’ long life anticorrosion treatment.

Integral mains isolator. Typical single phase unit requires 15 amp supply at 240v a.c.



♦ ♦

Arm mounted warning lights, ‘Stop’/’Noentry’ signs (signs available on raised ‘apex’ brackets for HGV traffic). Radio transmitters/receiver facility to allow remote (e.g. in-car) operation. Card access/token reader/intercom


♦ ♦ ♦

mounting posts in complementary designs. Hydraulic locking of arm in any position prevents unauthorised access. Induction loop or infra-red safety. Auto close and free entry/exit. Fixed beam rest or beam mounted rest for maximum road clearance. Lower extension for raised/high kerb.
