Portable Blade Truck Mounted Attenuator
High-strength reflective film portable Blade Truck Mounted Attenuator designed for superior rear-end collision protection on trucks and trailers and installed at the rear of trucks and trailers.
A "retractable safety shield" designed for the rear of trucks—deployed when parked to prevent underride in rear-end collisions, retracted when driving to avoid obstruction. It is both a compliant equipment and a lifeline.
Constructed using channel steel, stainless steel, and other durable materials for long-lasting performance.

Core Product Knowledge Q&A
Q1: What is this product and what is it used for?
A1: This is an anti-collision device designed for the rear of trucks and vans, commonly known as an "underride guard."
Core Functions:- Prevent Underride: Prevents smaller vehicles from sliding under the truck during rear-end collisions.
- Reduce Damage: Absorbs impact energy through its built-in buffer structure.
- Enhance Warning: High-visibility reflective film alerts following vehicles.
Q2: Can it really prevent underride? How does it work?
A2: Yes, it works through a three-part mechanism:- Height Matching: Installation height is about 100 cm, effectively blocking the front end of smaller vehicles (70-80 cm tall).
- Rigid Barrier: The main channel steel frame forms a sturdy barrier.
- Energy Absorption: The patented honeycomb aluminum structure absorbs impact force.
Q3: Is it convenient for daily use? Does it require frequent operation?
A3: Very convenient -- use it only when needed:- While driving normally: Fully retracted, taking up no extra space.
- During extended parking (e.g., loading/unloading, maintenance): Pull out and deploy (about 15 seconds).
- No daily operation required; use only when protection is needed.
Q4: Is installation complicated? Are professional tools required?
A4:- Professional installation recommended: Requires drilling and fixing to the rear chassis frame.
- Self-installation possible: Those with professional repair skills can refer to the installation guide.
- Tool requirements: Professional tools such as a torque wrench are needed.
Q5: Will it fit my vehicle?
A5:- Compatible vehicles: Various trucks with a total weight of 2-4 tons.
- Customizable dimensions: Can be tailored to your vehicle's specific measurements.
- Model options: Available with or without a step plate.
Q6: Is the quality reliable? Are there certifications?
A6:- Material certification: The buffer aluminum material has passed safety testing in Italy.
- Patent protection: The honeycomb structure holds a national invention patent.
- Process assurance: Stainless steel for rust prevention + electrostatic spray coating.
Q7: Is maintenance complicated?
A7: Essentially maintenance-free:- Monthly: Check that locks and latches are secure.
- Every six months: Lubricate the guide rails.
- Annual inspection: Check bolt tightness.
Q8: What happens if it gets damaged in a collision?
A8:- Minor collision: Normal deformation of the buffer structure, still usable.
- Severe damage: The buffer module or guide rails can be replaced individually.
Q9: Besides safety, what other benefits does it offer?
A9: Three additional values:- Reduces accident costs: Avoids high compensation payouts.
- Enhances corporate image: Demonstrates a commitment to safety.
Q10: What is the purchasing process?
A10: Four simple steps:- Provide vehicle information.
- Confirm customization requirements.
- Place order for production (7-10 days for standard models).
- Install and use.
