A safety roller is a device that both absorbs impact energy and converts it into rotational energy, thereby preventing fatal accidents for drivers and passengers. Also known as roller guardrail, rolling guardrail, roller guardrail, drum guardrail or road roller, widely used in sharp corners or curved areas. Effective shock absorption, guide the vehicle to the road direction, prevent major accidents.
The safety roller has a distinct color and self-lighting, which can effectively help the driver control the vehicle correctly. Safety drum guardrail is a new product. It is assembled by PU/EVA rollers and galvanized steel columns and beams. Roller guardrail and w beam guardrail function in a different way, it can absorb the impact, through the roller to guide the vehicle to the direction of the road, to prevent major accidents, while w beam does not. Roller guardrail is lighter than w beam guardrail, easier to install, easier to restore after installation, and easier to repair.
Applications:
Improve roadside visibility – SRB rollers are striped with high-intensity reflective sheeting that increases driver awareness and reduces accidents. Optional LED guide lamps can be added for even more exceptional visibility.
Safely redirects vehicles – Shock absorbing rollers convert impact energy into rotational energy, creating a smooth redirection. Occupant impact test results show SRB is the safest in its class.
Soften vehicle impacts – With 100% recyclable components, SRB is made of steel and flame-retardant, eco-friendly ethylene vinyl acetate (EVA) plastic, which softens vehicle impacts and reduces vehicle damage.
Modular system:
The Rolling Barrier Guardrail was built with maintenance as a
primary concern. A modular design comprised of D-shaped steel
rails, round steel-posts with EVA shock-absorbing barrels, and
frame rail lockers means that after incidents, individual parts can
be replaced without compromising the entire system thus reducing
maintenance costs.
Structural Design Of Each Part
Wear resistance is higher than 200% Wear resistance is higher than
200% to other anti-collision barrel materials in the market . Due
to its unique production process and process, Taicheng Rotary
Anti-collision Barrel has 3mm thick hard polyurethane protective
layer in the outer layer of the barrel. Its tensile strength and
bearing capacity are 2-3 times that of other anti-collision barrels
in the market.
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.
