Advancement in compaction machine technology in India

Compaction machine technology is going through evolution with the integration of a Tier 3/Stage IIIA engine and oscillatory variant features. Performance and productivity remain key issues for compactor manufacturers with firms keen to maximize output from their latest units. Ease of use and improved ergonomics are also design targets for manufacturers, who have long recognized that more comfortable machines can be operated more productively and for longer. Similarly, improved visibility allows machines to be operated more safely and more precisely, further boost overall productivity. The adoption of intelligent compaction technology allows the operator to optimize the job by prioritizing work and compacting areas smoothly.

Discussed below are a few of the advancements in compaction machine technology.

Oscillation technology in compactors

Oscillation technology eliminates vertical vibrations and offers high compaction performance while producing a non-damaging oscillation movement. This transfers less stress to the surrounding surface, enabling compaction in more delicate application areas, such as bridges, over pipes and close to residential areas. Additionally, when compacting against a cold joint, the risk of damaging the cold surface is reduced, and the material can be more effectively compressed to seal and protect the surface. The oscillatory movement of the drum can also improve surface smoothness, by re-aligning the material. Safety and ease of operation are enhanced by the expansive front windshield which maximizes the view down to the drum and spray bars. The structural pillar supporting the roof is located at the rear of the cab, meaning the three front glass panels provide operators with an entirely unobstructed view of the road.

Smart vibratory system in compactors

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 number of work cycles, as compared to the developed world. With articulated and pivot-steered tandem rollers of between 1.5 and 14 t, manufacturers are offering a large range of machines for practically any application in asphalt construction for all markets. This includes double vibration rollers, rollers with vibration and oscillation drums), combination rollers, vibration rollers with split drums and rollers with split vibration and oscillation drums.

Hydrostatic travel drive system in compactors

Hydrostatic travel drive system enables the compactor to have smooth directional changes between forward and reverse, without scuffing the material surface. Hydraulic motors are mounted directly to the rear wheel assembly, driven by a variable displacement hydraulic pump. Hydraulic power steering provides precise steering to maximize surface coverage with uniform tire coverage. Maintenance-free hydrostatic drive enables a smooth transition between forward and reverses direction without damaging the mat. Isostatic leveling cylinders keep the front tyres in even contact with the material surface at all times. Irregularities in the material are removed and excellent surface sealing is achieved. Manufacturers are offering eight-wheeled pneumatic tyre rollers that offer the smoothest compaction yet designed for roadway applications. High-performance compaction aids you to finish your job on time and within budget.

HVAC cabin in compactors

Compactors are now specially designed with operator comfort in mind. With its closed HVAC cabin and a more powerful engine, the compactor is highly suitable for heavier application usage. It is a product that will cater to activities as diverse as urban construction, road building, infrastructure, and mining. The soil compactor is also featuring a turbocharged aftercooled engine with an internal Exhaust Gas Recirculation system for ensuring the best-in-class fuel economy. Additionally, the optimized HVAC Cabin gives an excellent front and rear drum/nozzle visibility, making the drive and compaction process easier and safer.

In-built Compaction Meter

Manufacturers took special cognizance of this requirement and invested heavily in designing machines that offer the best-in-class safe operator environment. The in-built Compaction Meter is now being placed ergonomically for operator comfort thereby, helping in achieving the desired output, The steering wheel and console are designed to ensure fatigue-free operation and The cab platform is mounted on viscous mounts, to isolate it from any vibrations and to make the operator feel comfortable even during high amplitude passes. Moreover, compactors are now provided with isolated operator platforms, there is no feeling of vibration of the machine. This improves the stress-free operation of the machine & improves the operator’s efficiency. Hamm soil compactors are built with the patented design of three-point pendulum articulated joints. The three-point articulation joint connects the front & rear ends of the compactor & enables excellent directional stability and steerability & provides driver safety on difficult terrains and for the driver’s comfort.

Automatic water spraying system in compactors

Newer compactor models feature an automatic water spraying system with triple filtration that provides uniform coverage and variable flow, as well as helping prevent material pick-up. Furthermore, the two water pumps alternate during normal operation. In the rare event of a pump malfunctioning, a constant flow of water to the drum surface is automatically retained. The large 740 litres water tank allows for increased refill intervals, also helping to keep downtime to a minimum. Moreover, the tank’s low positioning affords the machine a low center of gravity for excellent stability and can be quickly and easily refilled at ground level.The double drum compactors are designed for simple servicing and maintenance. The swing-up hood provides complete access to the engine and hydraulic components, for efficient service inspections.

Conclusion

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 number of work cycles, as compared to the developed world. Global players who have entered the fray in India have been getting feedback from end-users and have been focusing their R&D towards machines that are specifically suited for India.
