Lightweight Aluminum Alloy Portable Vehicle Barricades with Foldable Design and

Tomarukun is a lightweight vehicle interception device specifically designed for road construction. Its main body is made of high-strength aluminum alloy, weighing only 25kg. With a foldable design and built-in wheels, a single person can easily handle transport and deployment.

The product integrates high-visibility engineering yellow warning with physical interception functions—it alerts oncoming vehicles to slow down from a distance during daily use; when a vehicle loses control and strikes the device, the lever mechanism lifts the front wheels, redirecting impact force vertically to the ground, while the bottom rubber pad brakes through friction energy dissipation.

Featuring a purely mechanical structure with no external power supply required, it can also be optionally equipped with an LED indicator board to meet nighttime usage needs.

• High-Strength Aluminum Alloy Main Body: The main frame is manufactured from high-strength aluminum alloy, combining lightweight properties with high strength. The material is inherently non-combustible and corrosion-resistant, suitable for long-term outdoor use.
• Foldable Support Arm: The front support arm is connected to the main body via threaded rods. When deployed, it folds down to form an interception posture; when stored, it folds up, reducing the overall volume by nearly two-thirds for convenient transport and storage.
• Stable Triangular Support Structure: When deployed, the main body and support arm form a stable triangular structure with strong impact resistance, ensuring that the device does not shift or tip over upon collision.
• Rubber Pad Friction Braking: The specially designed wear-resistant rubber pad at the bottom naturally conforms to the ground under the device's own weight. Upon impact, residual kinetic energy is converted into thermal energy through high-strength friction, achieving smooth braking.
• Bottom Mobility Wheels: Equipped with two industrial-grade mobility wheels for short-distance pushing. When deployed, the wheels are off the ground and the rubber pad bears the load, ensuring stability during braking; when stored, the wheels contact the ground for easy push-and-go transport.
• Lever Lifting Mechanism: At the moment of impact, the support arm lifts the front wheels through the lever principle, redirecting horizontal impact force vertically into the ground and significantly reducing the vehicle's forward momentum.
• Purely Mechanical Structure: The entire device features a purely mechanical design with no external power supply or electronic components required. It automatically triggers upon impact, eliminating concerns about circuit failure or signal delay.

Push to position, face oncoming traffic → Unlock buckle, lower the support arm → Rubber pad contacts ground, ready for use

Lift the support arm → Fasten the lock buckle → Push back to storage location

• Face traffic: Device front must face oncoming traffic
• Ground contact: Bottom rubber pad fully contacts the ground - do not leave it suspended
• Nighttime: LED indicator board recommended
• Positioning: Personnel must not stand directly behind the device
• Post-collision: Inspect structure for deformation or damage

A: It uses a purely mechanical structure. Upon impact, the lever lifts the front wheels, redirecting horizontal impact force vertically into the ground, while the remaining kinetic energy is dissipated as thermal energy through friction by the bottom rubber pad, achieving smooth braking.

A: Suitable for dry, level asphalt or concrete surfaces. Uneven surfaces such as potholes or cracks will affect rubber pad contact. Soft surfaces such as gravel or mud are not recommended.

A: No. After the front wheels are lifted, the rear wheels remain in contact with the ground at all times. The device is designed for braking, not overturning.

A: Yes. Weighing only 25kg with built-in mobility wheels and a compact folded size, one person can easily handle pushing, deployment, and storage.

A: Operating dimensions are 830*860*1080mm; folded dimensions are 830*1090*365mm. Height reduces from 1080mm to 365mm, with volume reduced by nearly two-thirds.

A: Yes. The product itself is high-visibility engineering yellow, and an optional LED indicator board is available for nighttime and low-visibility conditions.

A: Cones only provide warning and collapse upon impact. Tomarukun provides both long-distance warning and physical interception braking - dual protection in one device.

A: Concrete barriers weigh hundreds of kilograms and require a crane to move. Tomarukun weighs only 25kg - one person can push and deploy it in 1 minute, making it more suitable for temporary operations and rapid relocation.

A: No. It features a purely mechanical structure with no external power supply or electronic components required. It automatically triggers upon impact with no risk of circuit failure.

A: Check rubber pad wear and lock buckle flexibility monthly; check the surface coating quarterly and touch up paint if damaged. After any collision, inspect the structure for deformation.

A: Municipal road construction, road maintenance, power repairs, landscaping and pruning, lane closures, parking lot control, traffic guidance around schools, and other low-speed operation scenarios.
