Bonfigiloli Slew and Track Drive for Excavators

Component manufacturers are forming a close association with OEMs to meet the higher performance standards of equipment. P.P. Basistha takes a look.

Demand by OEMs for components such as hydraulics, transmission and drives, valves, and pump controls, is on the rise. According to component manufacturers, there was close to 15% rise in demand in 2017, as compared to 2016. Heightened activity in road construction sector and renewed traction in mining and mineral processing, has led to higher deployment of digging, extraction, loading, haulage, leveling and surface preparation equipment. This has resulted in greater demand for components. Improved offtake of mobile cranes is also a key demand driver.

OEMs, faced with the challenge to deliver higher levels of productivity, reliability, and optimization of their equipment, are setting stricter technical standards for component manufacturers. The standards are being set to justify the total lifecycle cost of the equipment. The other challenge for component manufacturers is to ensure timely delivery of their products, for which they are enhancing their production capabilities, and looking into backward integration with vendors to further streamline their production processes.

Bonfiglioli: Leading through experience

Kennady V Kaippally, Country Manager, Bonfiglioli India
Says Kennady V Kaippally, Country Manager, Bonfiglioli India, "Given the cost pressures inherent in the Indian market, energy efficiency and longer duty cycles are right at the top of customer expectations. Market trends in transmission systems of construction equipment are driven by the ever-increasing expectations of the customer from their equipment.

According to him, design of a transmission plays a vital part in delivering better efficiency and enhancing performance to withstand longer duty cycles. Both these objectives don't always run concurrent to each other, and many a times, achieving one may lead to undoing of the other. The challenge in design and manufacturing of a transmission lies in coming up with innovative solutions that meet all these objectives.

Bonfiglioli, having worked with all major OEMs across the globe in construction equipment, has decades of experience that enables it to provide solutions for diverse objectives. One such solution is its 700CK Series of drives used on tracked machines of 1.5 to 120 ton. These products are the result of its partnership with Kayaba Industries Co. All the hydraulic and mechanical functions like power drive, operating and travel speed, hydraulic and mechanical emergency braking system, and overload protection, are incorporated in a single unit. Extreme compactness, lightweight, efficiency, and smooth operation, are the key features of 700CK Series of track drives.

"It is our belief that with ever stringent emission norms, construction equipment will evolve to become more efficient than ever before and hybrid & electric technologies will come in for greater use as we move towards a greener economy," opines Kennady.

Bonfiglioli's deep commitment to the green economy has conditioned its entire organisational model, not only in the choice of markets, but also in the development of new products. In the last decade, the company has developed various products designed specifically for use with electric motors that offer a wide range of performance specifications.


Elaborates Kennady, "India, which is the largest Backhoe Loader market in the world, could benefit enormously with our products like wheel traction drives, launched under 600 Series Product Platform. This drive is specifically designed for backhoe loaders and other construction equipment. Each of the special 4-wheel traction drives is capable of reaching an output torque of 40.000 Nm, and is driven by a liquid cooled 30kW electric motor. The independent control of each wheel gives the opportunity for the backhoe loaders to be driven better on slippery surfaces. The Bonfiglioli 610 drives also increase the precision of the machine, making the manoeuvrability easier in tight spaces, for example, in building sites located at city centers. This solution enables OEMs to adopt hybrid technology that combines diesel & electric power, allowing energy generation and regeneration in a way that has never been done before for construction machinery."

Bonfiglioli's strength lies in its designing and developing customised solutions for a wide range of applications. This necessitates constant engagement with customers, right from the initial design phase, in view of the high level of customisation required. "Our local design centre in India enables an in-depth interaction with our customer, and that all of the required performance criteria are met so that we can develop a product that meets customer expectations," says Kennady, who informs that the company's upcoming 140,000 sq.ft facility adjacent to its plant at Thirumudivakkam in Chennai, will house an expanded design centre and a test lab to simulate specific customer requirements.

Bonfiglioli has been in India for nearly two decades, during which it has developed a range of power transmission products that permeate every walk of life such as industrial solutions that find applications across the breadth of industry, wind solutions for wind turbines, and mobile solutions for self-propelled agricultural, mining, warehousing and construction equipment. Along with its manufacturing facilities in Chennai and Pune, the company has offices for providing after-sales and after-market services in major industrial hubs of Mumbai, Delhi, Ahmedabad, Hyderabad, Kolkata, Bangalore, Coimbatore and other metros.
