MULTIQUIP AR12 STATIC SMOOTH DRUM ROLLER

Technical Description

The Multiquip AR12 Static Smooth Drum Roller is a compact, ride-on compactor designed for efficient asphalt and soil compaction tasks. It features a heavy-duty steel drum with a width of 32.3 inches and an overall operating width of 34 inches, suitable for precise smooth drum rolling applications. The roller operates with a vibration frequency ranging from 2,922 to 4,020 vibrations per minute (vpm), with a particular vibratory frequency range between 3,660 and 4,020 vpm, enabling effective compaction through variable speed control. Powering the unit is a reliable Yanmar 3-cylinder diesel engine, model 3TVN76, which is a naturally aspirated, water-cooled, indirect injection engine with a displacement of approximately 1.116 liters. This engine is known for its durability, fuel efficiency, and compliance with emission standards, delivering around 25 horsepower at 3,200 rpm. The AR12’s design incorporates a hydrostatic drive system that allows smooth, infinitely variable speed control for forward and reverse travel, facilitating easy maneuvering and precision operation in confined spaces. The drum and overall width dimensions make it highly suitable for compaction near curbs and walls, and it includes features like stabilizing rollers, twin scraper blades, and a vibration-isolated operator platform for enhanced operator comfort and productivity. This combination of powerful engine performance, efficient vibration frequency, and maneuverability makes the Multiquip AR12 a versatile and reliable choice for construction and paving projects requiring high-quality smooth surface finishes.
