The quickly erected mobile barrier "PEREKAT 750" refers to the transported barriers Features of the transported road blocker - quick deployment, no power supply, installation by one person. NOT REQUIRED for installation; foundation, concreting, additional fasteners to the roadbed. The road blocker is designed to work in two directions ENTRANCE and EXIT. In terms of its functional characteristics, the ROLLER road blocker is comparable to stationary road blockers. The ROLLER road blocker can act as an independent means of holding the car, and supplement the existing stationary anti-ram systems. In places where it is impossible to install stationary road bollards (for example, there is no electricity), transported mobile road bollards are installed. ROLLS are installed over the entire width of the road at a distance of up to 0.5 meters relative to each other. The anti-terrorist obstacle ROLLING with its toothed base is located in the direction of a possible "breakthrough" of the obstacle, the car, hitting an obstacle, raises the base of the road blocker and it rests against the bridge or the bottom of the car, blocking its further passage.... Additionally, the barriers can be connected with a chain. All ROLL bollards have wheels for transportation and a removable handle for transportation, which allows one person to install road bollards. When installed in the intended place, the wheels are unfastened, the handle is removed and the road bollard goes into working condition. Reflective stripes are applied on the working side of the road bollard.
