FAQ: Frequently Asked Questions about Road Construction

Why does construction equipment use the color yellow?

In shipbuilding, the yellow color indicates temporariness. Devices with a yellow background (such as signs or lights) take precedence over permanent signs by law, immediately notifying the driver of the presence of a work area.

Are cable bumps resistant to heavy vehicles?

Yes, our cable entry retarders are made of vulcanized dense rubber, designed to protect electrical and hydraulic cables from the transit of trucks and construction machines typical of the construction site.

How do mobile traffic lights work in pairs?

Our traffic light systems for construction sites are equipped with quartz synchronized control units. Once the "green" and "red" time has been set on the master control unit, the slave automatically adapts to manage the alternating one-way safely.
