Q1: What is this product used for?

A: It is a large vehicle crash attenuation device. It is mainly placed behind construction zones on expressways. If a driver accidentally enters the construction area, it can absorb impact and forcibly stop the out-of-control large truck, protecting the safety of construction workers ahead.

Q2: How is it different from plastic water barriers on the roadside?

A: The principle is completely different.

• Water barriers are static obstacles; they get knocked away upon impact by a large truck and are essentially useless.

• TOMARUZO does not "rigidly block." Instead, it uses the lever principle. Upon impact, it lifts the vehicle's wheels, directing the impact force to the ground for friction, using the vehicle's own weight to stop it. It has been verified through actual testing by the Japan Automobile Research Institute with a 10-ton truck impacting at 80 km/h.

Q3: Can it really stop a large truck?

A: Yes. According to authoritative test data, when a 10-ton truck impacts at 80 km/h, it can reduce the braking distance by nearly 5 meters. These 5 meters at an accident scene can mean the difference between life and death, effectively preventing the errant vehicle from hitting workers.

Q4: Will it catch fire after a crash?

A: The risk of fire is extremely low. Its core material is a patented aluminum alloy, which is flame-retardant and resists sparking upon impact. Compared to standard steel or some plastics, it effectively reduces the risk of secondary fires caused by fuel leaks.

Q5: Is this product heavy? Is it easy to transport?

A: Although a single unit weighs 132kg, it features a modular design.

• The entire system can be disassembled into 8 small components.

• On-site assembly requires only 2 people, with no need for heavy machinery.

• It is also equipped with rubber wheels at the bottom, making it easy to move short distances on the road.

Q6: How many units are in one set? How is it used?

A: One set includes 2 main buffer bodies. When in use, they need to be connected in series using 2 high-strength stainless steel connecting pipes and placed at the rear of the construction area. The top can also be equipped with an LED guide arrow board, ensuring high visibility even at night or in rainy/foggy weather.

Q7: Can it withstand sun and rain? How long does it last?

A: Its surface features a plastic-sprayed anti-rust treatment, making it highly weather-resistant and not prone to rust. The main body is made of aluminum alloy, which is also corrosion-resistant. As long as it is not involved in a severe impact accident, it can be reused for many years, making it a highly durable safety device.
