Metal highway guardrails or commonly known as guardrails – are used to prevent vehicles from entering oncoming traffic or going over cliffs. However, to achieve this, the barrier must be sturdy and firmly anchored to the ground. This means that conflicts with them are violent. If we remember high school physics, if the obstacle is immovable, it's like colliding with an oncoming vehicle, the same as your vehicle and moving at the same speed. To solve this problem, instead of metal beams, the new barrier uses a series of plastic cylinders that absorb some of the impact energy by converting it into rotational energy. When a vehicle hits a guardrail, even at an angle approaching 90 degrees, its cylinders change direction, returning it to its original trajectory and converting a high-impact collision into a less severe side impact.
The life cycle cost of a safety roller guardrail is better than that of a traditional guardrail system because it requires less repairs, replacements and maintenance. What's more, safety roller crash barriers reduce the risk of occupant injury.
The cost-effectiveness of the Safety Roller Crash Guardrail makes it an irrefutable crash barrier solution compared to other semi-ridged guardrail systems.
Product Features:
Shock absorbing system
Convert impact energy into rotational energy
Reduce speed impact
Redirect vehicle back to lane
Prevent driver and passenger deaths
Flame retardant and easy to install
Visually striking to alert drivers
The Taicheng Global Safety Roller Impact Barrier is a carefully designed barrier system that first absorbs impact energy and then converts the impact energy into rotational energy, thereby preventing fatal injuries.
Advantages:
The roller absorbs the initial impact of the collision and converts it into rotational energy
Front rail absorbs second impact
Rear rail absorbs third impact
Metal pipes inserted between the rails to strengthen the columns
Friction rotation stop plates mounted on the top and bottom of the drum act as clutch plates to reduce speed
Qingdao Taicheng focuses on the export business of transportation facilities and has rich experience in container packing and crating. The guardrail panels are packed with steel wire ropes, the columns are transported on pallets, and guardrail accessories such as gaskets are transported in ton bags. This assembly method ensures that the products arrive at the destination port and is convenient for loading and unloading.
1. The guardrail packaging adopts bundling method, which is convenient for loading and unloading. It also keeps the container balanced and facilitates transportation.
2. The guardrail columns are packaged in a tic-tac-toe bundling method, which is strong and easy for forklift loading and unloading.
3. Guardrail accessories are packed in large bags or simple wooden boxes for easy loading and unloading, and can be installed after arrival.
