Roller Barrier is a simple but highly effective anti climb barrier which uses fire resistant, self-extinguishing rotating plastic cups, threaded onto a central shaft, supported by brackets at regular intervals. The diameter of the plastic cups is large enough to prevent even the biggest hands from getting a grip.
Energy Absorption: Roller barriers are designed to absorb the kinetic energy of a colliding vehicle gradually, reducing the severity of the impact. The rolling motion of the barrels dissipates the energy over a longer distance, thus reducing the deceleration forces on the vehicle and its occupants.
Directional Control: When a vehicle impacts a roller barrier, the rollers rotate, which helps redirect the vehicle back onto the road, preventing it from crossing into oncoming traffic or colliding with fixed objects like trees or poles.
Versatility: Roller barriers can be used in various road and highway configurations, including straight sections, curves, and bridges. They can also be installed in both permanent and temporary settings.
Reduced Maintenance: Roller barriers are typically low-maintenance because the rollers rotate upon impact, minimizing damage to the barrier itself. This can result in cost savings over time compared to traditional rigid barriers that may require frequent repairs or replacement.
Improved Safety: Roller barriers are designed to enhance road safety by reducing the severity of crashes and preventing vehicles from leaving the road. They are often used in areas with a high risk of run-off-road accidents.
Compatibility: Roller barriers are compatible with other safety measures and technologies, such as guardrails, crash cushions, and electronic warning systems.
It’s important to note that roller barriers are just one type of road safety barrier system, and their effectiveness depends on various factors, including proper installation, maintenance, and adherence to safety standards and guidelines. Different regions and countries may have their own specifications and guidelines for the use of roller barriers in road safety applications.
Advantages:
Low cost
High flexibility to install and repair
Cable tension and post space can be adjusted.
Prevent vehicles from running off the road effectively
Absorb most sudden impact energy during collision
Good looking for the usage in open scenic spots
Anti-rust, anti-corrosion and anti-aging
Reflective strips can be pasted on the rotating barrel to warn drivers at night. When the driver drives to an area without lights or the lights are too dark, the reflective strip can refract the light, thereby reminding the driver to drive safely.
