Frequently Asked Questions
1. What is this product?
A telescopic crash guard installed at the rear of trucks and commercial vehicles to prevent smaller cars from underriding in rear-end collisions, protecting following vehicle drivers.
2. Which vehicles is it suitable for?
Primarily used for pickup trucks, box trucks, semi-trailers, and trailers. Standard models fit 2-4 ton vehicles with customization available.
3. How does it protect smaller car drivers?
Truck rears are high while car fronts are low, creating underride risk. The beam blocks this gap and absorbs impact force, protecting the driver's head and chest area.
4. What is the purpose of the telescopic function?
- Retracted while driving: Maintains ground clearance, visibility, and regulatory compliance
- Extended while parked: Forms active safety barrier during maintenance or work operations
5. Where is it installed?
Mounted via suspension system, fixed to the rear chassis or frame of the vehicle.
6. What types are available?
- With step plate: Provides access to cargo area
- Without step plate: Simplified collision protection design
7. Can the color be customized?
Yes. Standard high-visibility red and white available, plus custom colors upon request.
8. Why is it considered safer?
- Durable materials: Channel steel/stainless steel structure with aluminum alloy buffering
- Energy-absorbing design: Effectively disperses impact force
- Flexible telescopic function: Balances daily convenience with parked protection
9. What are its main advantages?
Resolves the conflict between protection and convenience: unobtrusive while driving, transforms into life-saving guard when parked.
10. Does it require professional installation?
Yes, professional installation is recommended to ensure secure mounting without compromising vehicle structure and safety.
