Quick Details

  • Place of Origin: Zhejiang, China (Mainland)
  • Brand Name: hankun

The Hankun radar speed trailer with full matrix display features the largest portable speed sign available. The giant display shows motorists’ speed in 66cm characters, warning them to slow down by flashing their excessive speed.






Commonly deployed in school zones, neighbourhoods and high accident areas, numerous options provide a strong measure of traffic calming unmatched by other roadway signs. 

Hankun engineers designed the new full matrix radar-speed display to be the largest, most visible display on the market. The compact, portable trailer is intended for use in neighbourhoods as well as alongside motorways.

When a motorist exceeds the speed limit, the display flashes the vehicle’s speed. For excessive speed, a selectable message flashes slow down or a frowning face symbol, together with optional flashing red and blue “police” lights that attract attention. 

Factory configured units show motorists’ speed in km/h. A regulatory sign above the display features changeable speed limit numbers for easy setup in any speed zone.

The speed limit sign and electronic display rotate to face traffic. The display’s LEDs have visors and shades that produce superior angularity and visibility.

The trailer’s see through design puts pedestrians in view, improving their safety—particularly in dangerous, high risk areas. The solar powered battery charging system provides longer run times.
