What feature is recommended for rollers operating in vibratory mode?

The recommended feature for rollers operating in vibratory mode is the automatic disengagement of the vibration mechanism before stopping. This is critical because it helps prevent damage to the roller and the surface being compacted. When the vibration mechanism is automatically disengaged before the roller comes to a complete stop, it reduces the risk of excessive wear on the equipment and helps maintain the integrity of the compacted surface. It also ensures the operator can manage the rolling operation more effectively by avoiding the potential for sudden stops that may disrupt the compaction process.

In contrast, manual vibration controls may not provide the same level of operational efficiency or safety. Operating at maximum speed at all times is not practical or beneficial, as it could compromise the quality of compaction and the safety of the operation. Finally, the ability to work without steering controls could limit the operator’s ability to effectively maneuver the roller, especially in complex or confined job sites.
