Civil engineering contractor Barhale is using proximity alert technology on its excavators to reduce health and safety risks.
Barhale subsidiary BCS has installed human form recognition cameras and a ‘digital thumbs-up system’ on six of its new excavators and ten diggers.
The machines use AI and other technologies developed by technology firm Safety Shield Global to identify when a person has stepped into an unsafe area around them.
The technology then produces an audible alert to the person in the unsafe zone and also to the driver.
Barhale said that the system has the capacity to report incidents by type and frequency, thus helping to improve safety behaviours on site.
Giving a (digital) thumbs up to safety
The digital thumbs-up system combines visual and audible signals to let machine operators advise other people when it is safe to approach them.
Using LED and sonic indicators, it replicates the established thumbs-up procedure that is well known in construction.
When an operator sees a thumbs-up signal from someone wanting to approach them, they will bring the machine to a controlled stop. They will then press the in-cab thumbs-up button to isolate the machine’s controls, which effectively disables it.
A ‘digital shield’ positioned outside the excavator or digger will then display a thumbs up, which means it is safe to approach the machine along the recognised corridor in line with the thumbs-up procedure.
Dave Lally, operations director at Barhale, said: “We believe this AI technology will benefit sites and personnel by ensuring the people/plant interface is managed in the safest possible way.
“The system will also give us insight into people’s behaviours, opening the door for further improvements in site safety and process.
"Adopting this kit on both new and existing machinery puts BCS right at the forefront of plant safety and will give our clients the additional peace of mind of knowing we are taking wellbeing to the next level.”
