Anti Rust Crash Cushion Attenuator Truck Mounted Attenuator

Designed by HANAI CO.,LED in Japan, this truck-mounted attenuator serves as a critical safety device for freight vehicles, widely recognized in the industry as the "lifeline" for truck rear-end protection. The system addresses the critical height differential between standard passenger vehicles (70-80 cm front height) and large trucks (100+ cm rear height), which aligns precisely with the head and chest level of drivers in following vehicles.

While the attenuator provides impact buffering during rear-end collisions, its primary function is preventing passenger vehicles from sliding underneath the truck's rear section. The installation height is specifically calibrated to vehicle models, positioning it at the exact level of the following driver's head and chest area. This strategic placement creates a crucial safety barrier that can significantly reduce injury severity during collision events.

A: This is a Telescopic Rear Underrun Protection System (RUPS) designed for large vehicles such as pickups, vans, semi-trailers, and trailers. Its primary functions are to prevent a colliding car from underrunning the truck's rear in a rear-end collision, absorb impact energy, and enhance road safety.

A: It is suitable for vehicles with a weight of 2.0 to 4.0 tons, including:

• Pickups, Box Vans

• Semi-trailers, Trailers

• Other large freight vehicles

A: The main structure is made of channel steel and stainless steel, providing sturdiness and corrosion resistance. The energy-absorbing section utilizes aluminum alloy and patented crushable material. The surface is finished with electrostatic spray painting for rust prevention and a clean appearance.

A: It employs a suspension-type mounting system, fixed to the rear chassis of the vehicle. Installation by a qualified professional is recommended to ensure proper fitment and safety performance.

A: It provides three core safety functions:

1. Underrun Prevention: Its height is specifically designed to match the front profile of passenger cars, blocking them from sliding underneath the truck.

2. Energy Absorption: Features an internal patented honeycomb crash structure (Patent No.: ZL 2006 1 0057817.8) to absorb and dissipate collision forces.

3. Enhanced Warning: Red/white color scheme with high-intensity reflective sheeting significantly improves visibility at night and in low-light conditions.

A: The protection bar can be retracted or extended. When not in use, it retracts to save space. It can be quickly pulled out and deployed when needed (e.g., during prolonged parking, maintenance, or roadside work). Some models include a step, facilitating access to the cargo area.

A: Yes. The standard size is Width 1800mm × Length 850mm × Height 350mm. Custom sizes and colors are available (standard color is red/white).

A: It weighs approximately 98.3 kg (varies slightly depending on vehicle specifications). Its lightweight design has minimal impact on the vehicle's overall load capacity.

A: Yes, it has passed overseas safety test certifications. Collision tests conducted by a Japanese vehicle laboratory have verified its effectiveness in shortening braking distance during a rear-end impact.

A: Standard rear bumpers are often fixed and lack dedicated energy-absorbing design. This product offers:

• Telescopic structure for flexibility and space-saving

• Patented energy-absorbing material for superior impact mitigation

• Combined underrun prevention and reflective warning, integrating active and passive safety features.

A:

• Long-haul freight and logistics fleets

• Vehicles at construction sites

• Temporary parking, vehicle maintenance situations

• High-risk road transport (e.g., highways, night driving)

A: The structure is robust. Routine maintenance mainly involves checking the mounting bolts for tightness and keeping the reflective sheeting clean. The energy-absorbing material requires no maintenance.
