Volvo’s B-Series compactors roll with the punches
SD115B: advanced drum control
Volvo Construction Equipment has introducing the new B-Series Stage IV/ Tier 4 Final-compliant soil compactors.
The SD75B, SD115B and SD135B soil compactors have Volvo’s advanced drum control system that allows the operator – via an easy-to-use console – to adjust the frequency and amplitude, compensating for changing soil types and conditions. Two frequency settings come as standard but five can be included as an option. High or low amplitude can be selected to adjust the drum’s dynamic force based on the job and material depth.
The optimised centrifugal force and auto-vibration feature also improve performance, ease of operation and productivity.
The traction system provides good climbing and traction capabilities in difficult applications, such as steep inclines or slippery surfaces, preventing wheel or drum spin.
The B-Series can be set up in three configurations and can be quickly converted from a smooth drum by clamping on a padfoot shell.
The new Volvo engine delivers high torque at low rpm for lower emissions and decreased fuel consumption without compromising on power. ECO mode now comes as standard on the SD75B, SD115B and SD135B models and can achieve up to a 40% reduction in fuel consumption by matching engine speed to operation mode. The eccentric design provides quicker ramp-up speeds at lower pressure, which increases fuel efficiency.
The passive regeneration automatically cleans the filters during normal operation without any input from the operator or negatively impacting on performance. A hydraulically-driven fan with variable speed draws power only when needed. Lower fan speeds reduce noise, resulting in greater operator comfort.
For reliability, the machines have a heavy-duty drum, centre joint and a front frame made from high quality steel with precise and consistent welds guaranteeing a strong structure. All components and electronics have been moved into the cab and mounted on the rear wall to protect them.
A tilting cab is standard on the B-Series to provide easy service access to all hydraulic components. The engine hood lifts electrically for extensive ground level access to the engine compartment. Maintenance and inspections can be conducted more efficiently with minimal downtime.
