Highway Safety Roller Crash Barrier

Typical characteristics of rotary crash guardrail Rotary crash guardrail using a large size rotating drum as the contact medium between the out-of-control vehicle and the guardrail, the material of the rotating drum is EVA and polyethylene blend with elastic characteristics, which can slow down the transverse impact process of the out-of-control vehicle, and the rotating drum can rotate around the column under a certain impact, driving the out-of-control vehicle guidance to return to positive The exact direction of travel.

Transforming the impact force into rotational kinetic energy can greatly absorb the impact force and reduce the impact, thus effectively reducing the consequences of traffic accidents.

The rotating barrel is made of EVA and polyurethane composite material, which is elastic and crash-resistant and wear-resistant, which can avoid the crushing of the rotating barrel when it is impacted and has strong resilience.

Key Features

1, high wear resistance is 3-5 times of natural rubber.

2, good oil resistance is 4 times that of NBR.

3, high mechanical strength its tearing strength, tearing strength and load bearing capacity is many times higher than ordinary rubber.

4, acid and alkali resistance, low temperature resistance, radiation resistance, solvent resistance, excellent performance

5. High bonding strength with metal skeleton plate.

6, the service life is high, can be up to decades, cost-effective is very high.
