Traffic Safety Driveway EVA Roller System Guardrail Crash Rolling
Barrier
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.
Applications:
This product can be widely used in the curve sections of highway.
the ramps of highway and continuous downhill sections.
Fan-shaped middle section of curved belt
Cliff or high drop slope section
Bridge terminals
area affected by crosswind
Tunnel entrance
And road sections where accidents occur frequently.
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.
