Movable Portable Vehicle Barricades
Tomarukun is a lightweight vehicle interception device designed for road maintenance and municipal construction scenarios, with "warning + braking" as its core function, providing a movable physical safety barrier for work zones.
The main body is made of high-strength aluminum alloy, weighing only 25kg, equipped with bottom mobility wheels and a foldable support arm. It can be pushed by hand for relocation in daily use, and forms a stable triangular support structure when deployed. A single person can complete the entire operation process without any mechanical assistance.
The warning function is achieved through high-visibility engineering yellow, providing visual alerts to oncoming vehicles from a distance. The interception function is based on a purely mechanical lever principle—upon impact, the front wheels are lifted, horizontal impact force is redirected vertically into the ground, and the bottom rubber pad dissipates remaining kinetic energy through friction.

Structure and Functional Features
Structural Composition
The main frame is manufactured from high-strength aluminum alloy, providing overall support while combining lightweight properties with impact resistance. The front support arm is foldable and forms an interception posture when deployed. A specially designed wear-resistant rubber pad is installed at the bottom for ground contact to generate braking force. Two industrial-grade mobility wheels are provided for short-distance pushing - when stored, the wheels contact the ground; when deployed, the wheels are off the ground and the rubber pad bears the load.
Functional Features
- Lever Lifting Mechanism: Upon impact, the front wheels are lifted, redirecting horizontal impact force vertically into the ground, significantly reducing the vehicle's forward momentum.
- Purely Mechanical Structure: No external power supply or electronic components required - automatically triggers upon impact, eliminating concerns about circuit failure or signal delay.
- Stable Triangular Support: When deployed, the main body and support arm form a triangular structure, ensuring the device does not shift or tip over upon impact.
- Self-Conforming Rubber Pad: The device's own weight ensures the rubber pad naturally conforms to the ground without additional adjustment, achieving smooth braking through friction energy dissipation.

Application Scenarios & Usage Methods
Applicable Scenarios
Road construction • Maintenance operations • Power repairs • Landscaping and pruning • Lane closures • Parking lot control • School surroundings
Usage Methods
Standalone Use
Place one unit at a single work point, providing both warning and interception functions.
Combined Use (Recommended)
Place cones 20 meters ahead for early warning → Place Tomarukun in the middle for interception → Work zone behind.
Lined Use
For wider work areas, arrange multiple units side by side.
Product Q&A
Q: Why use Tomarukun instead of ordinary traffic cones?
A: Cones only provide warning and are useless upon impact. Tomarukun adds physical interception on top of warning - an extra layer of protection, providing construction personnel with additional safety assurance.
Q: Concrete barriers can also stop vehicles - why not use them?
A: Concrete barriers are too heavy - moving them requires a crane, which is time-consuming and labor-intensive. Tomarukun can be pushed by one person and deployed in 1 minute, making it more suitable for temporary operations that require frequent relocation.
Q: Can one person really push 25kg?
A: 25kg is about the weight of a bag of rice. With wheels at the bottom, it's easy to push on flat ground - no heavy lifting required.
Q: Is deployment and storage complicated?
A: Not at all. Deployment is three steps - push to position, unlock the buckle, lower the support arm. Storage is the reverse - lift the arm, fasten the buckle, push away. Once you're familiar with it, it takes less than a minute.
Q: Can it still be used after a collision?
A: Minor impacts don't affect it. After a severe collision, check the structure for deformation - if it's intact, it can continue to be used. No need to discard it after a single hit.
Q: Can the product be used in salt spray environments?
A: Yes. The surface is treated with rust-proof coating, making it suitable for coastal areas, ports, and docks. Rinse off salt residue with clean water regularly.
Q: Can it stop a large truck?
A: The product is primarily designed for sedans and medium to small vehicles. Large trucks have greater weight, so stopping distance will increase - assess based on on-site vehicle types before use.
