Anti Collision Yellow Traffic Management Attenuator Lightweight
A movable crash barrier designed to actively stop errant vehicles at construction zones before they enter the work area.
Problem Solution
At roadwork sites, the worst-case scenario is a vehicle ignoring signs and barriers, crashing straight into the work zone. RMHs Mini Vehicle Stopper is built for that "just in case" moment — it's not just a warning panel, but a physical device that actually stops the vehicle.

Advantages Over Traditional Barriers
- One-person operation - Only 20 kg net weight, with built-in rollers. Push to move, drop to deploy. No crane or truck needed.
- Folds for storage - Folded size: L1100×W664×H200 mm, fits in a car trunk. Take it anywhere.
- All-weather durable - Engineering yellow/orange, electrostatic coated for outdoor rust resistance.
- Works with LED arrow boards - Highly visible at night or in fog.
- Fire-safe aluminum - In extreme cases (e.g., vehicle fire), aluminum does not burn and produces no flying fragments, preventing secondary disasters.
Vehicle Stopping Mechanism
Upon impact, a lever mechanism lifts the front wheel of the vehicle, redirecting most of its kinetic energy downward. The remaining energy is absorbed by dual buffer modules at the base, then transferred to a high-friction rubber pad. The result: a stable, controlled stop - no sudden ejection or overturning.
Usage & Maintenance
- Deployment: Open the folded structure and push the device to the desired location - no fixed installation required.
- Mobility: Built-in rollers support short-distance pushing with good ground adaptability.
- Maintenance: Periodically inspect rollers, rubber pad, and buffer modules for wear. Clean the surface with a neutral detergent if needed.
- Applicable Speed Range: Recommended for low-speed construction environments (e.g., urban roads, maintenance work zones, internal access roads of construction sites).
Application Scenarios
| Scenario Category |
Specific Applications |
| Municipal Road Construction |
Temporary excavation, pipeline repair, manhole cover replacement - perimeter protection for work zones |
| Highway Maintenance |
Pavement patching, line marking, guardrail repair - low-speed mobile operations |
| Temporary Work Zones |
Landscaping trimming, streetlight maintenance, bridge inspection - short-term road occupation |
| Traffic Isolation & Warning |
Accident scene isolation, lane closure, temporary traffic diversion |
| Construction Site Entrances/Exits |
Temporary protection outside site gates to prevent unauthorized vehicle entry |
| School/Campus Temporary Control |
Vehicle control during pick-up/drop-off hours or campus events |
| Parking Lot Partial Closure |
Parking space repair, equipment installation - areas requiring temporary isolation |
Typical Deployment Methods
- Standalone Use - Placed at a safe distance in front of the work zone as a physical crash barrier
- Combined Use - Paired with RMHs safety arrow signs or LED arrow boards - warning first, then protection
- Multi-point Deployment - Placed at multiple directions around the work zone to form a complete protective perimeter
Speed Reminder
This product is designed for low-speed construction environments (recommended vehicle speed ≤ 50 km/h). Suitable for urban roads, maintenance work zones, internal access roads of construction sites, etc. For highway operations, please use dedicated truck-mounted attenuators.
Frequently Asked Questions
Q1: What is this product?
This is a mini vehicle stopper (portable crash barrier), brand RMHs, made in China. It is designed for low-speed work zones such as road construction and municipal projects to prevent vehicles from entering the work area.
Q2: What is its core function?
Upon impact, the device uses a lever mechanism to lift the front wheel, directing kinetic energy to the ground. Combined with dual buffer modules and rubber pad friction, it achieves a smooth, controlled stop, preventing the vehicle from entering the work zone.
Q3: What are its main features?
- Lightweight - Only 20 kg net weight, with built-in rollers for one-person operation
- Foldable - Folded size: L1100×W664×H200 mm, fits in a car trunk
- High visibility - Engineering yellow/orange color, compatible with LED arrow boards
- Durable - High-strength aluminum profile + outdoor electrostatic coating, rust-proof and weather-resistant
- Flame-retardant & safe - Aluminum does not burn; no flying metal fragments in case of impact-related fire
- Eco-friendly - 100% recyclable aluminum
