The SAKAI SW504G 4.5 ton double drum 51″ asphalt roller delivers exceptional performance on paving projects while prioritizing operator safety and minimizing equipment downtime. Equipped with the innovative integrated Guardman® auto brake assist system, the SW504G utilizes millimeter wave technology to detect personnel or objects behind the roller. This advanced system automatically slows or stops the compactor in the event of an imminent collision, significantly reducing the risk of accidents and potential injuries on the job site. The detection capability even works through common dust and steam on the asphalt mat as well as during night paving.

By incorporating Guardman technology, the SW504G fosters a safer working environment for paving crews and those in the surrounding area. Additionally, the system can help to prevent costly equipment damage caused by accidental collisions.
