Meeting tight tolerances on a timeline is vital for paving operations, and carrying out compaction work safely and efficiently is made easier with the latest technologies that automate tandem roller functions. Tandem roller tech tools keep operators and project managers focused on producing a high-quality mat that meets regulatory requirements while doing that work as efficiently as possible. They lower the costs that come from equipment wear-and-tear, unnecessary fuel use, and financial penalties for a job out of spec. These three technology tools keep operators focused on ensuring the work is done correctly while requiring fewer inputs — a sure way to produce the highest-quality road surfaces.
SAKAI Guardman with Echelon Mode prevents potential collisions
SAKAI America’s Guardman, now with Echelon Mode, utilizes either millimetre-wave radar or 3D LiDAR, depending on the model, to detect potential collisions with personnel or equipment, warn the operator progressively, and automatically brake the roller to prevent accidents if needed.
SAKAI says that the Echelon Mode feature was developed based on operator feedback after the initial release of Guardman. The update specifically addresses the need for tandem rollers working together in echelon rolling formation, typically used on highway-class paving projects. With Echelon Mode, operators get all the safety benefits of Guardman without the concern of false alarms triggered by another roller in intentional close proximity. The system intelligently monitors distance to the lead roller, ensuring that both the operator warning and braking is only initiated when an imminent collision risk is detected.
Echelon Mode optimizes tandem rolling, enabling closer, more efficient echelon formation to maximize productivity while retaining all of the safety benefits of Guardman by providing reliable collision prevention without generating false alarms. The proximity indicator provides operators with real-time feedback on the distance between rollers, allowing for proactive adjustments and preventing unwanted braking, and Echelon Mode can be easily toggled on and off via the Guardman display screen.
