MULTIQUIP AR40* STATIC SMOOTH DRUM ROLLER

Technical Description

The Multiquip AR40* Static Smooth Drum Roller is designed for efficient asphalt and granular soil compaction with an overall width of 4.5 ft and a turning radius of 11.5 ft, providing excellent maneuverability in confined spaces. It features a 51.2-inch wide smooth drum vibrating at frequencies between 3,540 and 10,790 vibrations per minute (vpm), enabling adjustable compaction force for diverse applications. Powered by a Yanmar 3TVN88 engine—a 3-cylinder, 4-cycle, naturally aspirated, water-cooled diesel engine with a 1.642-liter displacement and direct injection system—the engine delivers reliable performance optimized for fuel efficiency and low emissions. This engine model offers approximately 26.9 kW (36 hp) at 3000 rpm, with durable construction including enhanced block cooling, a mechanical governor, and a distributor-type MP2 fuel injection pump that ensures precise fuel delivery and reduced emissions. The AR40* roller’s hydrostatic drive allows smooth variable speed control for precise operation, while its articulated steering and tight turning radius enhance jobsite productivity and accessibility. Robust steel drums and proven vibration isolation minimize noise and operator fatigue, while integrated features such as water tanks (not specified but typical for Multiquip rollers) aid in asphalt compaction. This combination of powerful Yanmar engine technology and well-engineered compaction components makes the Multiquip AR40* an effective and versatile choice for medium-duty compaction projects requiring static smooth drum rolling.
