The system uses sensor technology to automatically apply the brakes when an object comes within four metres of the vehicle, bringing it to a complete and controlled stop.
FM Conway uses sweepers across its core highways services, but mostly for its surfacing division. Although sweepers typically move at slow speeds, the nature of surfacing works often means that a large number of construction personnel are in close proximity.
John Tobin, asset manager at FM Conway, said: “We challenged ISS to deliver a new solution in auto-braking technology in the hazardous area of road sweeping. Following a successful trial we are now pleased to have been able to roll this out across our sweeper fleet.”
The operator is using the technology to support already stringent supervision and training to further minimise risks. “The new system will enable us to track how often the technology is being deployed – meaning that we can identify the need for further training to ensure that safe practices become fully embedded across our teams,” says Tobin.
Oliver Hoadley, sales director, ISS said: “The radar is fitted to the back of each vehicle and can detect objects up to 30m. If anything gets within six metres, an alarm sounds in the cab along with an LED warning light. However, we have developed the system a stage further by integrating programmable auto-stop technology. If the vehicle continues to move past a set distance, as specified by the customer, the brakes are then applied.
“We’ve also ensured that the radar is the exact width of the sweeper meaning that there is minimal interference from other objects, such as street furniture and parked cars, which is a common cause of false alarming.”
ISS says the new system operates on a 24GHz frequency, making it one of the most powerful and accurate reverse radar detection systems. It is also installed in a way that is approved by VOSA as well as numerous vehicle OEMs.
