Offering safety boundaries and vehicle interception in road maintenance and construction areas
Product Overview
In road maintenance and municipal construction, safety is always the first line of defense. Tomarukun is built for exactly this purpose—a lightweight vehicle interception device standing at the perimeter of the work zone, using high-visibility engineering yellow to draw a clear safety boundary for oncoming traffic.
It is not just a warning sign, but a reliable physical barrier. Weighing only 25kg and made of high-strength aluminum alloy, it features a foldable design with built-in mobility wheels, allowing one person to easily handle transport and deployment. In daily use, its high-visibility color warns oncoming vehicles to slow down from a distance. When an out-of-control vehicle intrudes, the built-in lever mechanism lifts the front wheels at the moment of impact, redirecting horizontal impact force vertically into the ground, while the bottom rubber pad grips the road surface tightly to forcibly intercept the vehicle.

Product Advantages
Lightweight and Portable - Single-Person Operation: Weighing only 25kg with built-in mobility wheels and a foldable design, one person can independently handle transport, deployment, and storage from warehouse to site - no mechanical equipment assistance required.
Space-Saving - Reduced Transport and Storage Costs: Folded height reduces from 1080mm to 365mm, with volume decreased by nearly two-thirds. Increased transport loading capacity, reduced warehouse footprint, and lower logistics costs.
Warning and Interception in One: High-visibility engineering yellow provides long-distance visual warning, alerting oncoming vehicles to slow down in advance. If a vehicle ignores the warning and forcibly intrudes, physical interception is immediately activated. One device completes both early warning and braking functions.
Short Braking Distance - Stable Performance: Upon impact, the lever lifts the front wheels, redirecting horizontal kinetic energy vertically into the ground, combined with rubber pad friction energy dissipation. Stopping distance is only 8.7 meters at 60km/h and 3.0 meters at 40km/h - braking performance is predictable and consistent.
Safe and Eco-Friendly - No Secondary Hazards: The aluminum alloy body is impact-resistant and non-combustible, producing no sparks upon collision - eliminating fire hazards. Impact force is dissipated through ground conduction and friction, avoiding severe shock to vehicle occupants from rigid collisions. Material is 100% recyclable.
All-Scenario Adaptability - Minimal Maintenance: Outdoor electrostatic coating provides rust and weather resistance, unaffected by temperature or humidity. Optional LED indicator board available for nighttime construction needs. Daily maintenance only requires checking rubber pad wear - no professional servicing needed.

Stopping Principle
Upon vehicle impact, the device lifts the front wheels to redirect impact force to the ground, combined with rubber pad friction to bring the vehicle to a stop.
Three Steps:
Impact trigger: The vehicle's front wheels strike the front support arm, activating the mechanical structure.
Lift and redirect: The lever lifts the front wheels, redirecting horizontal forward impact force vertically downward into the ground - significantly reducing the vehicle's forward momentum.
Friction braking: The remaining force is transferred to the bottom rubber pad. The pad presses firmly against the ground, generating friction that converts kinetic energy into thermal energy, gradually decelerating the vehicle until it stops.
Usage Steps
Deployment: Push to position → Face oncoming traffic → Unlock buckle and lower arm → Rubber pad contacts ground → Ready
Storage: Lift arm → Fasten lock buckle → Push away
Key points: Face oncoming traffic / Rubber pad must contact ground - not suspended / Use LED board at night
Product Q&A
Q: What is Tomarukun?
A: A lightweight vehicle interception device for road construction, combining warning and braking functions.
Q: How heavy is it? Can one person operate it?
A: 25kg, with built-in wheels and foldable design - one person can easily push, deploy, and store it.
Q: What is the braking principle?
A: Purely mechanical. Upon impact, the lever lifts the front wheels, directing impact force to the ground, while the rubber pad brakes through friction energy dissipation.
Q: What is the stopping distance?
A: Approximately 8.7 meters at 60km/h and 3.0 meters at 40km/h (on dry asphalt roads).
Q: What are the advantages over traffic cones?
A: Cones only warn; Tomarukun both warns and intercepts.
Q: What about compared to concrete barriers?
A: Concrete barriers weigh hundreds of kilograms and require a crane. Tomarukun weighs only 25kg - one person can push and deploy it in 1 minute.
Q: Can it be used at night?
A: Yes. It features high-visibility yellow and an optional LED indicator board is available.
Q: What scenarios is it suitable for?
A: Road construction, maintenance, power repairs, lane closures, parking lot control, and other low-speed scenarios.
Q: What daily maintenance is required?
A: Check rubber pad wear and lock buckle flexibility monthly; check surface coating quarterly and touch up paint if damaged.
