Selecting the right choice of compactor

Soil compaction is a significant process for any construction project and requires special attention and quality compaction equipment to achieve satisfactory results. Compaction is about reaching your goals in the fewest passes possible. When choosing a compactor one looks for the efficiency of technology and the ability to direct more force toward the target and away from the machine. Soil compactors are used in soil to rearrange the particles and reduce the void ratio and increase soil density. The compaction of soil increases the shear strength and load-bearing capacity of the soil. Modern-day compactors are being integrated with advanced technologies. The demand for the equipment has been driven by highways and rural roads. The compaction of soil increases the shear strength and load-bearing capacity of the soil. The compaction of the soil is provided by the combined action and force of the vibrating and oscillating roller drum, and the weight of the compaction machine which is used.

The trend that has been witnessed in the Indian compaction market is the movement towards vibratory compaction from the earlier predominantly static rollers. The technology helps send pressure waves into the soil surface in different directions leading to the particles achieving a dense state of orientation. Just as in the case of the other types of construction equipment, contractors have realised that the initial higher capital investment is bound to pay off in the long run, given the cost savings achieved due to the lesser number of passes. Manufacturers are also focusing on coming out with machines that are fuel-efficient and require minimal maintenance, all adding to the good news for contractors. With competition, intensifying suppliers are concentrating on coming out with machines that would ideally suit Indian working conditions, where typically these machines would be put through more work cycles. Discussed below are different types of soil compactors available in the Indian market and being used for multiple project applications.

Compactors with vibratory system

The latest models of compactors comes with a vibratory system that drives energy into materials and away from the operator. Varied amplitude settings make the machine a good fit for multiple applications. The rear-axle concept enables unmatched stability, gradeability and traction, while also improving operator visibility. An improved operator platform offers enhanced visibility and comfort. Service points can be accessed from the ground, while the engine can be reached easily through a tiltable platform and hood.An optional, easy-to-install padfoot shell kit helps the roller perform in cohesive soils and to penetrate more deeply when needed. The compactor’s application includes include state and national highways, city and municipal roads, PMGSY (urban-rural connectivity), railway embankments, airports, mining haul roads, port distribution hubs, Formula 1 roadways, industrial developments, internal roads for power and steel plants, and smart city developments.  The machine models are manufactured to deliver savings after the purchase, particularly when servicing the machine. Convenient maintenance points ensure work is completed quickly. Service points can be accessed from the ground, while the engine can be reached easily through a tiltable platform and hood.

Compactors equipped with high static linear load

The latest compactors feature high static linear load and can be used universally in inner-city projects and for compaction on motorways. The newer model ensures that maximum compaction force is always available, and vibration works immediately once the nominal frequency is activated. For the driver, the acceleration of the vibrating unit is imperceptible. The automatic vibration system ensures that the vibration is shut off as soon as the compactors stop moving. This prevents over-compaction and guarantees high-quality surfaces. The three-point articulation in the new compactors guarantees outstanding directional stability, impressive stability when negotiating curves, and a high level of safety against overturning. This means that the compactors deliver outstanding manoeuvrability and excellent compaction, even on uneven terrain. The models are driven by a robust, water-cooled 4-cylinder engine in accordance with CEV Stage IV. If the driver selects the average speed, the machine operates in ECO mode. This mode reduces fuel consumption by up to 20%, as well as lowering CO2 and noise emissions. It is also equipped with large-sized hydraulic components and a smart control system.

Compactors with Intelli-Compaction feature

Models are now available with provides Relative Compaction value, which helps in achieving consistent and uniform compaction throughout the patch. The digital display shows High/ Low frequency and Amplitude values for compaction control. The Intelli-Control, Intelli-Compaction and Intelli-Load are all integrated with Livelink, our advanced Telematics Technology, which enables predictive maintenance, location and monitoring to achieve high uptime of the equipment. The Compaction Metre ensures uniform compaction as the operator exactly knows where to stop and the number of passes that are required to achieve the desired density. This leads to uniform compaction density and savings in fuel as well as time. It helps in reducing the number of passes and also avoids over-compaction. The cab platform is mounted on 4 viscous mounts, to isolate it from any vibrations and to make the operator feel comfortable even during high amplitude passes.
