Safety is an increasingly important factor in the road building industry and at Sakai we have made it our mission to address. Every year lives are tragically lost, personnel are severely injured, and equipment is damaged from backup accidents all with costly results to paving contractors. These losses could be prevented in many cases. Further, employees are increasingly hard to hire / retain and a worksite safety focus is an attractive employer attribute.

That’s where Sakai Guardman auto brake assist system technology comes in. A first for the asphalt paving roller industry, Guardman detects personnel, equipment, or objects behind the compactor and automatically brakes when a collision is imminent. The operator does not need to intervene.

Guardman works by using millimeter radar or 3D LiDAR (depending on the roller model) in full integration with the machine’s hydraulic drive and SAHR (spring-applied, hydraulically released) braking system. A sophisticated intelligent controller compensates for compactor speed and day or night visibility. This safety option even works through dust / steam and was designed to be used for paving next to walls without worry of false alarms. Guardman has been proven in Japan for years with commercial asphalt paving contractors.

Watch the Guardman demo video below to see how this safety system works in various jobsite scenarios including backing up to standing personnel, kneeling personnel, metal objects, unseen personnel coming from behind cover, and a demo of basic proximity detection.

Guardman availability is noted below. This system is not retrofittable due to numerous machine components that are specifically engineered for this system. Save lives, prevent injuries, and defend your assets with Sakai Guardman.
