The DASSAULT manufacturing site in Biard (86) wanted to limit intrusions by reinforcing its vehicle control system. Prior to our intervention, it was managing flows using a rising barrier. Noting damage to the barrier, it wanted to add a retractable harrow with spikes. The aim is to improve site safety without impacting on the existing vehicle flow. The Bolloré BR 500 harrow provides an effective solution to filtering and anti-intrusion problems.

The Herse BR solution
The BR Harrow is part of our perimeter protection category, enabling you to control vehicle access to a sensitive area in one direction only. The harrow is made up of spikes whose orientation (inwards or outwards) can be chosen as required. It lowers and lifts on command, allowing vehicle access.
Choosing the BR harrow means choosing :
1 – A preventive access control gate
This type of perimeter protection allows you to reduce the number of intrusions by guaranteeing optimum security from the moment you enter the site:
- Deterring attempts to cross by force
- Immobilising a vehicle by puncturing tyres during an unauthorised transit attempt
- Smooth management of incoming and outgoing vehicles
2 – A compact solution
The Harrow incorporates a series of puncture points and a barrier to manage the flow of traffic.
3 – Simple installation
Thanks to its modular design in a 1-metre box, the harrow is easy to install in a specially designed civil engineering recess.
4 – Customise your BR Harrow
Depending on a number of factors, such as the space available and the level of security required, you can choose :
- Harrow size: from the BR 300 harrow (3 metre passage) to the BR 600 harrow (6 metre passage)
- The height of the spikes: long (200 mm) or short (130 mm)
- Optional equipment: Automatic barrier (recommended), two-colour warning lights (recommended), remote control panel with 3 buttons (raise, lower, emergency stop of harrow), and much more…
