Portable Traffic Signals are intended to be used primarily for the control of vehicular traffic at road works where it is necessary to close a section of carriage-way such that a single lane must be used alternatively by traffic from opposite directions.
The equipment is comprised of two electronic controllers known as “MASTER” and “SLAVE” mounted in a trailer unit that is capable of being “split” with each unit being positioned separately on the work site.
The dual-trailer system allows the trailers to be connected together so that it can be towed as one individual unit. This capability allows the system to be towed to the job site using one vehicle. This system can be setup on the work site in less than 15 minutes by one person.
The Portable Traffic Signals are capable of operating under manual or automatic control and each separate unit is fully self-contained and powered by battery with diesel motor/alternator or solar charging system. The fully lockable steel enclosure protects the controller, batteries and motor from the elements and vandalism.
“Master” and “Slave”
Communications between the MASTER and SLAVE is by radio or cable link. The Portable Traffic Signals have an in-built fail safe system such that they will automatically revert to flashing yellow operation should a hazardous, incompatible or fault condition occur.
