Traffic Control Solutions with Portable Vehicle Barricades for Road Maintenance and Municipal Construction Safety
On road maintenance and municipal construction sites, safety is always the top priority. Tomarukun is a lightweight vehicle interception device built for exactly this purpose—it stands at the perimeter of the work zone, using its striking engineering yellow to send a clear signal to oncoming traffic: construction ahead, please slow down.
When an accident occurs, it doesn't just collapse upon impact like ordinary traffic cones. Its built-in purely mechanical lever mechanism lifts the front wheels the moment of collision, redirecting impact force vertically into the ground, while the bottom rubber pad grips the road surface tightly, converting residual kinetic energy into thermal energy through friction. At 60km/h, it brings the intruding vehicle to a firm stop in just 8.7 meters—a distance sufficient to hold the safety line for construction personnel.

Product Advantages
1. Lightweight and Flexible - Single-Person Operation
Weighing only 25kg with built-in mobility wheels, one person can easily handle pushing, deployment, and storage - no mechanical assistance required.
2. Foldable Storage - Efficient Transport and Storage
Folded height reduces from 1080mm to 365mm - volume reduced by nearly two-thirds. Increased transport loading capacity and reduced warehouse footprint.
3. Warning and Interception Integrated - Dual Defense
High-visibility engineering yellow warns oncoming vehicles to slow down from a distance; when a vehicle ignores the warning and intrudes, physical interception is automatically triggered. One device completes both functions.
4. Purely Mechanical Braking - Stable and Reliable
Designed on lever principle - no external power supply or electronic components required. Automatically triggers upon impact with no risk of circuit failure or signal delay.
5. Short-Distance Braking - Rapid Response
Stopping distance of only 8.7 meters at 60km/h and only 3.0 meters at 40km/h - bringing the vehicle to a stop before it can rush into the work zone.
6. Safe and Eco-Friendly - No Secondary Risks
High-strength aluminum alloy is impact-resistant, non-combustible, and produces no sparks upon impact - eliminating fire hazards. Material is 100% recyclable.
7. All-Weather Applicability - Strong Durability
Outdoor electrostatic coating provides rust and weather resistance. Optional LED indicator board available for nighttime construction needs.

Main Frame
Overall support, withstands impact
Front Support Arm
Foldable, triggers lift upon impact
Bottom Rubber Pad
Contacts ground, generates braking force

Folding Lock Buckle
Locks or releases the support arm
On-Site Deployment
Positioning: Push the device to the designated position behind the work zone, facing oncoming traffic.
Unfolding: Release the folding lock buckle and extend the front support arm outward.
Contact: Ensure the bottom rubber pad makes full contact with the ground. If the ground is uneven, adjust the position to eliminate any suspension.
Pack-up: After use, lift the front support arm upward, fasten the folding lock buckle, and push to the storage location.
Usage Precautions
Always face oncoming traffic
Rubber pad must contact the ground - not suspended
LED board recommended for nighttime work
Personnel must not stand directly behind the device
After a collision, inspect the structure for deformation
Routine Maintenance
After each use: Remove sand and mud from the rubber pad
Monthly: Check rubber pad wear and lock buckle flexibility
Quarterly: Check surface coating - touch up paint if damaged
Product Q&A
Q: Why can Tomarukun achieve short-distance braking?
A: The key lies in the kinetic energy conversion path. Upon impact, the lever lifts the front wheels, redirecting the vehicle's horizontal forward kinetic energy vertically into the ground, significantly reducing horizontal impact force. The remaining kinetic energy is converted into thermal energy through high-strength friction between the bottom rubber pad and the ground—rather than relying on the vehicle's own braking system—enabling braking within a short distance.
Q: Why are the front wheels lifted when a vehicle strikes the device?
A: The front support arm and the main body form a lever through a hinged connection. When the vehicle's front wheels strike the support arm, the impact force is transmitted along the support arm to the pivot point, utilizing the lever principle to lift the front wheels upward—similar to how a car jack lifts a wheel. The lifting action is synchronized with the impact and requires no external power.
Q: Will the device still work if the vehicle hits off-center?
A: Yes. The front support arm spans the full width (830mm), so most frontal and partial side impacts can effectively trigger it. For severely off-center approaches, it is recommended to use cones to guide vehicles toward the front.
Q: Can the device withstand multiple impacts in succession?
A: The main structure can withstand multiple impacts within its design limits. The rubber pad is a normal consumable part—regular inspection and replacement restore original braking performance.
Q: Could a vehicle jump over the device and rush into the work zone?
A: Not within the rated speed range. The device disrupts the vehicle's driving and steering capability by lifting the front wheels, while braking through ground friction energy dissipation. With a stopping distance of only 8.7 meters at 60km/h, it is far shorter than the typical safety distance for work zones.
Q: Can Tomarukun stop trucks or SUVs?
A: Braking data is based on 2000cc-class sedan testing. Heavier vehicles will have longer stopping distances due to greater mass. The product is primarily designed for passenger car protection—for heavy vehicles, assessment should be based on site-specific conditions.
Q: Can the device be used on curves or slopes?
A: Yes, but placement requires attention. Curves and slopes affect driver visibility and reaction time. It is recommended to place the device before the curve entrance or before the hilltop to ensure oncoming vehicles have sufficient distance to see and react.
Q: How is the device prevented from being knocked away upon impact?
A: When deployed, the main body and support arm form a stable triangular structure. The 25kg self-weight, combined with friction between the bottom rubber pad and the ground, ensures the device remains in place upon impact and will not be thrown off.
