Anti Collision Highway Crash Barrier Traffic Safety EVA Roller Barrier
Features of Safety Roller Barrier:
1. Reduce speed by stopper board
2. Guide reflective leads a driver to drive safely
3. Recyclable material (eco-friendly)
4. Help a vehicle turn back to the road by its spinning when the
car crashed the rollers laterally
5. Minimize fatal damage of people and vehicles by absorbing
collision shock
6. Reduce costs in repairing and maintenance due to Roller’s
resilience.
7. Stopper boards help prevent larger accidents by slowing down
Roller’s spin
8. Can be used for many years, less cost.
How safety roller barrier works?
1. The rotating barrel converts great shock from vehicle collision
to rotational energy to absorb shock.
2. Upper and lower frames adjust tires of large and small vehicles
to prevent the steering system function loss.
3. The three-dimensional structure of D-shaped frame and buffering
bracket distribute and absorb the 2nd shock.
4. Props at an interval of 0.7 m increase bearing power to prevent
accident vehicles from going over the guardrail and turning over
into a dangerous area.
5. The product has a rotating barrel made of EVA with excellent
shock absorption power, three-dimensional buffering frames and
dense props supporting the frames.
The rotary drum is made of EVA (ethylene-vinyl acetate copolymer)
as the main material, and more than 30 kinds of auxiliary materials
such as PE (polyethylene) and related chemical auxiliaries are
added at a certain temperature and pressure. It has high
flexibility and resilience, and also has high temperature
resistance, and continuous working temperature is between -30℃ and
70℃.
The reflective strip is attached to the rotating cylinder. When
driving at night, through the lighting of the headlights, the
outline of the route can be better reflected, and the vehicle can
play a better induction role to improve driving safety.
Application field:
The product can be widely used in highway curves.
Highway ramps and continuous downhill sections.
Midsection of curved belt.
Part of a cliff or high drop slope.
Bridge the dock.
