LED Direction Arrow Retractable Mobile Vehicle Barrier With Patent Certification

LED direction arrow patent certification Absorb the impact force Mobile Vehicle Barrier

The tractor is installed in the rear of the road maintenance vehicle. When the driver accidentally bumps into the device, the internal special aluminum structure can absorb a large amount of impact force with its unique shock absorption design. The internal patented aluminum energy-absorption unit (Patent No.: ZL 2006 1 0057817.8) is specifically designed for high-speed impacts. It has passed overseas safety tests and can significantly reduce impact forces, thereby ensuring the safety of both personnel and vehicles.

Q&A for RMHs QYC Rear Impact Attenuator

Q1: What is the main purpose of this product?
A: This is a rear-mounted crash cushion trailer designed specifically for road construction. Installed behind the work vehicle, it provides powerful warning and traffic guidance under low-visibility conditions while effectively absorbing rear-end collision impact through its patented energy-absorbing structure, thereby protecting workers, the vehicle, and equipment ahead.

Q2: What is the core safety technology, and is it certified?
A: The core safety technology is the internally patented aluminum energy-absorption unit (Chinese Patent No.: ZL 2006 1 0057817.8). Its unique shock-absorbing design can dissipate a significant amount of impact energy. This technology has passed professional overseas safety tests and is formally adopted.

Q3: The product seems heavy. Is it easy to move and deploy?
A: Very convenient. Despite its robust construction and weight of approximately 129 kg, the product features integrated wheels at the bottom. Simply secure it to the rear of the construction vehicle using bolts, and it can be towed directly at speeds up to 70 km/h, enabling rapid relocation and deployment.

Q4: How effective are the LED arrow board and warning lights in adverse weather?
A: The product employs a multi-layered, redundant warning system: a high-brightness LED arrow board (direction-adjustable), a top-mounted yellow strobe beacon, an optional alarm, and high-grade red-and-white reflective sheeting. This combination ensures exceptionally high visibility and warning effectiveness even at night or in rainy/foggy conditions.

Q5: If the unit is hit in a collision, is it scrapped? Are repair costs high?
A: Not necessarily, which is a key economic advantage. The patented energy-absorption structure features a modular design. After a collision, if the external main frame is not severely deformed, typically only the internal, replaceable crushable energy-absorption module needs to be swapped out. This avoids scrapping the entire unit, making repairs straightforward and far less costly than purchasing new equipment.

Q6: Can the arrow board section be adjusted? How is it handled when not in use?
A: Yes. The arrow board section is designed with a manual lifting/lowering function, allowing adjustment of its display height. When not in use during transport or storage, it can be lowered to a stowed position, saving space and facilitating transportation.

Q7: Can the product dimensions and color be customized?
A: Yes. We offer flexible customization services. While the standard main body color is yellow/orange, dimensions and specifications can be tailored to specific customer requirements. We also support manufacturing based on provided drawings to meet the unique needs of different vehicles and projects.

Q8: Is installation complicated? Does it require professional tools or personnel?
A: Installation is straightforward. The main process involves securely fastening the unit's base to a suitable position at the vehicle's rear using the provided high-strength hardware (e.g., bolts). It is recommended that personnel with basic mechanical knowledge perform the installation to ensure it is firmly fixed and to conduct regular checks on the fasteners' tightness.

Q9: Which vehicles and scenarios is this product suitable for?
A: It is primarily suitable for various vehicles requiring temporary, mobile, or stationary work on open roads, such as road maintenance trucks, sweepers, and mobile construction vehicles. Common applications include routine maintenance, emergency response, accident management, and other work zones on highways, national, and provincial roads.

Q10: Compared to simple crash barrels, what is its greatest value?
A: Its greatest value lies in the dual safety assurance of "active protection + active warning" and high operational mobility. It not only absorbs impact like crash barrels but also proactively warns and helps prevent accidents through intense active lighting and audible alerts. Furthermore, its ability to be towed at high speed transforms safety protection from a "static zone" to a "dynamic follow" system, truly safeguarding mobile work operations.
