SAKAI America will show the new SW884ND 79-inch asphalt roller at World of Asphalt/AGG1 2024, featuring its new Guardman safety technology.
Guardman is integrated into roller hydraulics on the production line and uses detection tools to identify when personnel or objects are in front of or behind the roller. It provides alerts to the operator, but also slows and brakes the machine to avoid collisions without operator intervention. The system can work through dust and steam, next to walls, or at night. The roller shown at World of Asphalt is the first from SAKAI with both front and rear detection and braking, while other Guardman models are rear-only.
Also on display will be a preview of the battery-electric HV620E walk-behind double-drum roller, a prototype developed in conjunction with Honda. Its Mobile Power Pak lithium-ion battery system was developed to be removable and swappable on the job site, making for more convenient charging, and enabling contractors to power up their batteries without moving the whole machine.
