Apr. 21, 2010 – The new SD115 and SD130 ranges of single drum soil
compactors from Volvo Construction Equipment feature a new operator
environment and a host of design upgrades, including smart power mode
Smart power mode optimizes the engine and hydraulics output as well as the cooling fan speed to match the application requirements. This results in more accurate compaction and means the engine runs at a lower speed – significantly reducing noise, mechanical wear, emissions and fuel consumption.
With two preset frequencies and five optional (five settings standard on models SD130DX/F and SD160DX/F) and dual amplitude to suit, the new models offer among the highest compaction forces in their class, resulting in minimum number of passes and increased coverage. The SD115D weighs 11,490 kg (25,330 lb) and is powered by a 97 kW (132 hp) four cylinder turbocharged diesel engine, while the SD130D weighs 12,815 kg (28,252 lb) and boasts a larger engine output of 119 kW (162 hp). The high power-to-weight ratio and dynamic force combine to achieve good material density in the minimum number of passes. This combination, along with a low centre of gravity results in good gradeability, with both units favoured for slope compaction. Ultra Grade traction system is also available, allowing steep climbing – up to 75% theoretical gradeability without interruption in traction.
Volvo says that customer input has played a large part in the design of the new machines, with features such as remote greasing bank, improved work lights, shields on sensors, cloth seats and easy access to engine oil drain – all being the direct result of user feedback. Generally, ease of use and maintenance is a high priority with the SD range of compactors from Volvo. A one piece engine cover and tiltable cab gives straightforward access to engine and hydraulics respectively, making daily maintenance less of a chore.
The operator’s life is also made easier, with the new models featuring large, air conditioned and sound insulated ROPS protected cabs, which are mounted on premium quality shock absorbers. The console, gauges and switches are all conveniently close to hand, and visual and audible warnings are fitted to alert the operator’s attention when necessary. For applications where cohesive soils, such as clay, are to be compacted, both models can be quickly and easily converted from smooth drum compactors into padfoot variants, via the use of padfoot shell kits. Another option is the height adjustable dozer blade, which allows the operator to fill in trenches or strike off fill material, providing suitable conditions for subsequent compaction.
For projects where full documentation of the compaction process is required, Volvo Construction Equipment offers its CompAnalyzer as an option. The system displays and documents a continuous readout of compaction work, displaying up to 747,000 m2 of work area. The data can help customers detect any weak points on previously compacted areas, allowing them to be recompacted and stabilized. Volvo also offers a smaller compaction gauge that gives operators a constant overview of the relative ground compaction, current vibration frequency and the bounce mode.
