Protect your site and people with SOSEC®

Safeguard your entrance and cut HSE interventions - instantly

Mobile traffic and pedestrian management

SOSEC is a revolutionary, award winning approach to securing work sites and is the UK’s first mobile barrier/gate system. It harnesses the sun’s energy, combining SOlar power and SECurity in a simple, rugged, visible and mobile platform. It is ideal for use within the UK’s construction, highways, mining, retail, event and emergency markets.

The concept, developed by Kent-based Green Gate Access Systems, was designed to answer the growing need to provide public safety and temporary site security where power provision is not practical, but security demands are high.

As staffing and security costs rise, SOSEC offers a security solution with no running costs, saving money and the environment.

Instant work area demarcation

SOSEC combines a five-metre automatic traffic barrier with optional full-length drop skirt and LED lights to control vehicles with a rugged, locked and self-closing gate for pedestrians. Designed around a rugged, galvanised, 8mm steel platform with a compact footprint, it can easily be positioned with a forklift or telehandler and is instantly ready to provide site security.

Solar powered public safety

Solar power and power storage are unique elements of the SOSEC system. A high-capacity solar panel allows the barrier to operate up to 900 times per day – even in an average British winter. For short term sites and ultimate flexibility, SOSEC can be delivered with a battery store for up to one-month’s use.

Choose our combined barrier and gate, solo barrier or solo gate, to suit your site. Access control can be customised to site needs with a variety of state of the art controls. Supplied with simple key code and radio remotes as standard, additional options include 700m remotes, mobile phone opener, swipe cards, key codes, open/close timer or simple entry/exit on approach to name a few.

Each unit arrives fully tested to BS EN13241-1, force tested to BS EN 12445 and complies with the gate safety standards as defined in DHF TS011.
