SAKAI SV510D STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SV510D is a robust static smooth drum roller designed for effective soil compaction in sand, gravel, rockfill, and semi-cohesive materials. It features a Cummins QSB4.5 diesel engine delivering 148 horsepower, providing reliable power output for demanding compaction tasks. The roller has an operating weight of 23,525 lbs, with 12,700 lbs on the front drum and 10,825 lbs on the rear axle, ensuring substantial ground contact and compaction force. The machine’s smooth drum vibrates at a frequency ranging from 1,650 to 2,200 vibrations per minute (vpm), with adjustable nominal amplitude from 0.04 to 0.08 inches for precise compaction control. It generates centrifugal forces between 38,580 lbs (low mode) and 50,710 lbs (high mode), optimizing soil density and stability. A turning radius of 136 inches allows good maneuverability despite its large size. The vibration system uses a hydraulic motor controlled via amplitude and solenoid valves, enabling efficient vibration speed and force adjustments to prevent machine overstress and enhance versatility. The integrated traction control system balances torque between the front and rear drives to maintain traction on slopes or uneven terrain. The roller’s design combines mechanical and hydraulic systems to seamlessly control drum speed and amplitude, maximizing compaction efficiency while protecting components from damage due to improper vibration settings. This machine is suitable for infrastructure projects requiring high compaction performance combined with operational reliability in varied ground conditions.
