In road maintenance and municipal construction, safety is always the first line of defense. Tomarukun is a lightweight vehicle interception device built for exactly this purpose—it stands quietly at the perimeter of the work zone, using its striking engineering yellow to draw a clear safety boundary for oncoming traffic.
It is not just a warning sign, but a reliable physical barrier. When an out-of-control vehicle intrudes, the built-in purely mechanical lever structure lifts the front wheels at the moment of impact, redirecting horizontal impact force vertically into the ground; simultaneously, the bottom rubber pad grips the road surface tightly, converting residual kinetic energy into thermal energy through high-strength friction to complete the braking process.

Braking Distance: 40km/h ≈ 3.0m / 60km/h ≈ 8.7m
Applicable Scenarios: Road Construction • Municipal Maintenance • Temporary Work Zones
Weighing only 25kg with built-in mobility wheels, it is easy to push and maneuver. From warehouse retrieval to on-site deployment and storage, one person can handle the entire process independently - no forklift, crane, or additional manpower needed.
Folded height reduces from 1080mm to 365mm - volume decreased by nearly two-thirds. More units per truckload during transport, more units per square meter in storage - logistics and warehousing costs are reduced simultaneously.
High-visibility engineering yellow warns oncoming vehicles from a distance about construction ahead; if a vehicle ignores the warning and intrudes, physical interception is automatically triggered. One device completes both early warning and braking functions.
Upon impact, the lever structure lifts the front wheels, redirecting horizontal kinetic energy vertically into the ground. The remaining energy is dissipated through friction by the bottom rubber pad. The braking process is smooth, independent of the vehicle's own braking system, with stable and predictable stopping distance.
By lifting the front wheels to redirect horizontal kinetic energy vertically into the ground, combined with rubber pad friction dissipation, braking is completed before the vehicle can rush into the work zone. Stopping distance at 40km/h is only 3.0 meters.
The high-strength aluminum alloy body is impact-resistant and non-combustible, producing no sparks upon collision - eliminating fire hazards. Energy is dissipated through ground conduction and friction, avoiding severe impact shock to vehicle occupants from rigid collisions.
Outdoor electrostatic coating provides excellent rust and corrosion resistance, adapting to various climate conditions. Unaffected by temperature, humidity, or altitude - performs reliably across different climate conditions throughout the country.
No installation, no wiring, no configuration needed - deploy and it's immediately on standby. With no electronic components, there is no need for periodic calibration or software updates. Exceptionally low barrier to entry - ready to use right out of the box.
Tomarukun employs a purely mechanical structure to achieve vehicle braking, requiring no external power supply or electronic control. The braking process consists of three stages:
The vehicle's front wheels strike the front support arm, and the impact force is transmitted along the support arm to the pivot point, activating the lever mechanism.
The lever principle lifts the front wheels upward, redirecting the vehicle's horizontal forward kinetic energy vertically into the ground, significantly reducing horizontal impact force—essentially "lifting the vehicle onto its toes" and depriving it of forward driving capability.
The remaining kinetic energy is transferred to the specially designed rubber pad at the bottom, converted into thermal energy through high-strength sliding friction between the rubber pad and the ground. The vehicle gradually decelerates until it comes to a complete stop. The stopping distance is only 8.7 meters at 60km/h and only 3.0 meters at 40km/h.
It is accomplished through purely physical means, stable and reliable.
