Concrete equipment manufacturers have been carrying spate of improvisations in their product categories to deliver higher productivity and availability, P.P. Basistha takes a look at the recent advancements.
There is all round development in the concreting equipment industry. Manufacturers have been presenting newer solutions across the product verticals so as to cater the newer requirements of the contractors, working in high rise construction and most notably concrete road infrastructure projects. The machineries, manufacturers argue, consisting the batch mix plants, are capable of delivering higher concrete output in conjunction with batching concrete based on desired specifications of the contractors. While the pumps are capable of pumping various grades of concrete at higher pressure at longer heights and distances. The transit mixers are able to retain the appropriate quality of concrete, manufacturers also claim, while transporting them across longer lead distances while retaining the desired concrete quality.
Gujarat-based concrete equipment manufacturer Apollo Inffratech Pvt. Ltd. is offering concrete batch mix plants indexed to the finished material throughput requirements of present design specifications of concrete roads. “Typically, slip form pavers with widths of 5.5 meters for paving 250 mm thick pavements at 1 metre/ minute, needs to be backed by 120cum/hr batching plants. For project with two-lane pavement of 9-10 meters, backup concrete throughput is required from 160 cum/hr plants. We have an elaborate portfolio of 100-120-160-180 cum/hr batching plants for concrete road and other infrastructure projects. We also offer lower capacity plants between 20-90 cum/hr,” informs Mr. Mitul Patel, Apollo Inffratech.
He continues, “Exact rated throughput to our plants with faster uptime is enabled by twin shaft mixers with holding hopper. Twin shaft Mixer facilitates release of the mixed concrete based on gravitational force, thus minimizing wear of plates. This is on contrary by pushing system for releasing concrete offered by the competition products. Further, the advantage of twin shaft mixers is that they can handle varied sizes of aggregates ranging from 80-120mm based on the project requirements.”
He adds, “Concrete mixed design needs to be delivered and laid at faster cycle times, so that the exact cement to water ratio is maintained without being hardened prematurely. Faster release of the concrete based on twin shaft mixers facilitates the retention of the batched concrete mix design” Apollo’s concrete batch mix plants are fitted with BHS or Sicoma twin shaft mixers.
Mr. Patel further mentions, “Our plants pass the cost benefit to our customers based on their programmable logic controlled enabled functionality (PLC). The PLC takes direct signal from the load cells, ensuring the desired mixing quality and accuracy, enabling the contractor to obtain the specified concrete output. This also delivers faster cycle time of the plants.”
Apollo Inffratech, which manufactures its concrete batch mix plants at Rajpur in Mehsana, Gujarat, has a tie-up for marketing US origin HEM slipform pavers with paving width from 2.75-13.5 meters. The pavers deliver the right quality of vibration at right frequency for getting the appropriate paving. The vibration in the vibrator can be undertaken individually and collectively. The company has a joint venture with Carmix (Italy) for self-loading mobile mixers.
Sharing details about the company’s product support, Mr. Patel informs, “We provide application engineering support to the road contractors on the required quality of additives to be mixed in concrete and batching for obtaining the proper quality mix. Products and parts support is ensured through our well placed components delivery system across the country.”

Expanded range & pumping abilities
Putzmeister India has introduced its new ‘E-Smart series’ of concrete stationery pumps. The new E-Smart, s-valve technology pumps are available with concrete pumping capacities of 40-50-60-70-90-100 cum/hr, manufactured at its Goa factory with most of the components indigenously developed.
According to Mr. Parminder Gabri, Director-Sales, Putzmeister Concrete Machines, “The new series of E-Smart pumps feature very high levels of efficiency and safety owing to their design and hardware. Higher levels of operational efficiency in the pumps are delivered through the new Human-Machine-Interface mechanism (HMI). HMI delivers information on the pressure, temperature, RPM, fuel consumption. Information on the number of strokes is also shown in the equipment. This allows the pump operator to set and reset the machine according to the pumping requirements. Besides, it also allows him to undertake any preventive maintenance, if necessary.”
Sharing further details, he says, “One of the notable features of our new pumps is that they have one centralized location for operation of the hydraulic-electrical and engines. This is in contrast to our previous pumps which had individual operating systems for the hydraulic, electric, and the engines. With independent operating systems, it was difficult for the operator to precisely identify the area of defects. With centralized integrated operating systems, it will be now quite easy for the operator to identify and rectify the defect in the particular operational area of its occurrence.”
Putzmeister plans to increase marketing of the pumps in high-rise and metro projects. The company expects that with the new advanced operational and safety features, the E-Smart series will outpace the demand for its existing range of stationery pumps. Mr. Gabri says, “With the new pumps we will upgrade our existing users as well as those looking for higher productivity and efficiency. Operational support to the pumps is provided through our trained operators who are with the machines during the initial period of commissioning.” Putzmeister provides service back up through its pan India 20+ parts depot and 40+ services centers.
Putzmeister currently has 5000+ pumps working in India. Based on the requirements of the customers, the company upgrades and refurbishes the machines in total or in parts. Further, based on the requirements of the customers to pump the desired quality of concrete, Putzmeister also provides complete solutions through its specialists in its Concrete Project Division. The company has 150 resident service engineers and service centers across four regions of the country. The German origin, concrete stationary and boom pumps manufacturer, based in Verna, Goa, markets its pumps through its own marketing channels in India.
