The company is offering a 11-ton vibratory compactor which has a four-bearing design that makes compaction more effective compared to the two-bearing design, and also due to the deflection of the shaft, amplitude or frequency with total applied force, which is a static and dynamic load put together, reduces the number of passes, and thereby reduces overall operational cost as well. “This superior product enhances productivity over a span of say 25 km or 300,000 tons of the main mix soil to be compacted, cutting down the job’s timelines and bringing better returns on investment to the machine owners,” says Sundaresan.
Operator comfort is enhanced by reducing the vibrations of operator’s platform. Lesser operator fatigue leads to operator efficiency in compaction and overall productivity. The company provides 360-degree maintenance of the machine, the engine, and its hydraulic system for optimum uptime.
AMC is provided for all Ammann products, under which, the company’s service personnel visit the customer on a regular basis to provide maintenance support. The company has 18 touchpoints across India for supply of spares & service.
Elaborating on the acquisition cost of an Ammann plant, he informs, “Many new players are coming up to meet demand in the lower, price-conscious segment of users in India. They are offering products at a 20 - 30% lower price, but if you observe closely, you will see where they are compromising; for instance, you might notice that the plant cold feeders are of old design i.e. the customer will have to build a foundation to raise the plant’s level. Since these are not permanent plants, shifting them from one location to another every 1-2 years, requires building a foundation wherever they are to be installed, which means that the resultant cost of the plant will be much higher, despite the initial lower purchase price.”
He informs that Ammann has a system to increase efficiency and fuel economy, inbuilt sensors to check the moisture content in the aggregate and bring with increase or decrease the flame length of burner, thereby bringing down the fuel consumption from 5.5 litres to 4.8 litres or even more depending on ambient temperature, and accordingly the fuel consumption comes down. “Our burners have been optimized and we offer LDO, FO, LSHS, and Gas (CNG/PNG/LPG) as per the demand,” he says.
Ammann has complete in-house facilities for product fabrication, laser welding, robotic welding, laser cutting, or plasma cutting. “We are able to ensure quality control at every stage of production and come up with a superior product. For example, to put up a cold feeder, a local manufacturer will have to build a ramp, else the loader will not dump the bitumen. But we have designed our feeder in such a way that if you have a compacted surface you can put up the cold feeder there, which saves the cost of the ramp every time,” informs Sapru. Most modern thermodrum with different heat zones plays a vital role in overall plant efficiency besides effective screening and optimum hot bin capacity.
Currently, over 75 Ammann & Apollo plants are in operation with 30% RAP in India and the company has around 5 Ammann plants which are running with hot and cold RAP (up to 40% combination i.e. 15% hot (coarser particles) which can go into the drum and another 25% with the cold RAP). “Ammann has 100% hot recycling RAP and 100% cold recycling RAP in the global market, including technologies like cold mix, hot mix or warm mix. We have installed over a hundred of such plants all over the globe, but in India, we offer 60% RAP technology. The first unit will be supplied to GR Infra,” adds Sundaresan.
Our drum mix plants and batch mix plants can go up to 25-30% RAP and now with RAP increased to 60%, Ammann is ready to provide solution to the Indian Market, adds Sunil Sapru. “We are also working closely with CRRI for plastic additions like shredded plastic, which requires melting point of above 140 or 145 degrees. We have tried this in our batching plants at two sites in UP and in Continuous plants as well. The results have come out very well.”
He informs that the company is working with many PWD engineers, highway engineers, and agencies like IAHE for training and upskilling the NHAI teams. “Unless the government makes it mandatory that only certified operators can operate a machine, the CE industry players will not invest in setting up training institutes for operators and technicians. But we have to start now if we want to achieve 100% training in say 5 years.”
