Failures of ?Gearbox and Drives?

It is a pain area for the plant management team when the gear drive fails and it is more difficult to arrive at the correct cause of failure. S Sengupta & A Ray Chowdhury from Sprat Consultancy elaborates on some of the common causes of failures, also suggests remedial measures.

The idea of putting pen to paper regarding gear drives seems to be a daunting task. One is apprehensive as to where to begin and to what degree to write is a nerve racking proposition as majority of the readers are qualified, sound practical engineers who are associated with industrial plants such as cement, power, metals, etc. Experience confirms that a meaningful insight on the subject requires around three working days and if fourth day could be added by way of site visit with discussions on practical problems, works out a ?win-win? situation for all.

An endeavour is however being made to jot down some thoughts that may serve as pre curser from selection to use of drives. The order of narration is not sacrosanct and not all encompassing. It is just a brief write up on few attributes hoping it will provoke the mind of concerned personnel be it users or project/technical personnel. Use of gear drives in a system does not imply just operational; it encompasses what happens within a drive train and requirements to achieve desired performance life hence design life.

In many instances over the past 38 years, we have come across failures in drives caused by lack of insight or foresight or lack of correct data or its understanding during selection of drive. A common failure, but not frequent, is lack of perception of what all is to be handled &/or power required to drive the system.

An example that readily comes to mind is in a greenfield cement plant around early 1980s: the external consultant confirmed motor power, application, operating hours per day, etc. and wanted a drive with a safety factor (SF) of 2.5. This particular gear drive was 1 amongst 65 others. It was the only one that was prone to frequent failure to the tune of once every three months. Review of actual operating data confirmed actual power consumed was 40 per cent higher than confirmed during project design & planning leading to premature failures.

Another instance of premature failures observed in a cement plant in Western India of a twin drive bucket elevator where input drive was through fluid coupling. After a year of satisfactory operation failures commenced with regularity in one of the gear drives in the arrangement. As they were imported gearboxes not much hue and cry was raised initially. Replacements from two indigenous producers also failed in the same manner and frequency leading to a pantomime at the plant. Analysis of the drive arrangement confirmed power consumed by individual drives differed by over six per cent. In such a scenario, failure was inevitable and plant further confirmed that after a year one drive motor had burnt out requiring rewinding. Rewinding is common accepted process but what is equally important is that in a twin drive synchronisation of input power is of utmost importance of within two per cent variance. Since synchronise of input power no further failures occurred over a decade.

There are many other instances of failures we often recollect as observed over the last four decades. In all instances failures have taken place for:

Incomplete or inadequate clarity of specification at initial stage.
Lack of appreciation of specification, which is more dangerous.
Hypothesis by OEM of likely operational parameters viz a viz specification thus incorrect supply.
Augmenting capacity after year/s of use and not sharing data with supplier or supplier not appreciating information conveyed which must be well defined.

In short whatever are the circumstances in life (we consider gear drives also a form of life) it takes two to speak the truth to form an understanding and thus realisation. In the field of machine dynamics the same applies; dialogue between user and supplier must be continual and without inhibition or prejudice. In other words partnership is required with frank exchanges, irrespective of how insignificant the information may appear, to eliminate misgivings consequently failures.

The more this realisation dawns on all in a B2B scenario and quicker the better for all concerned resulting in reliability of operations. Failures are phenomena that cannot be totally ruled out even with best intentions of user and supplier. Any failure, irrespective of its occurrence, within or beyond the warranty period or after extended period of use is relevant at all times towards better and improved designs unless failure occurs beyond design life of rolling elements. This information should be shared with factual details unambiguously.

It is common for most designers to design critical drives, irrespective of type/size &/or application considering a life of 100,000 hours for gears/pinions and around 60,000 hours for bearings. Indirectly, to a large extent, bearing life sets the set point for case hardened and ground gears/pinions although theoretically it has an infinite life.

The question therefore arises why premature failures occur within warranty period or shortly thereafter. One of the primary reasons for failure beyond warranty period is governed by the quality of lubricating oil being used. Often quality is misunderstood with viscosity grade. Quality per ?say? has no relation to viscosity grade; it refers to the cleanliness of the oil.

Lubricating oil needs to be maintained clean and the desired level is NAS6 for industrial application other than turbine drives. This value of NAS6 also applies to wind mill drives and speed increasers as opposed to high speed drives. The cleanliness value of NAS6 does not readily register with users and to some extent with suppliers of gear drives. To put it mildly, check oil directly from a sealed barrel supplied by OEM for its NAS value and you will invariably find it anywhere around NAS10 or worse. Do not assume it happens only with indigenous supplies as it is far from the truth. Checks conducted with top brand sealed oil drums, indigenous or imported, confirm this is normal and common.
The onus thus lies with users to appreciate why oil cleaning is required and how does it improve the performance as well as life of the gear drive. It is safe to conclude, which concurs with our observation, that organisation which maintains lubricating oils health is less prone to premature failures. They invariably enhance the life of their drives by any where up to 30% higher than others for same drive conditions. This phenomena can be observed in an organisation &/or plant to plant operations but sadly data and findings are rarely pooled.
Another disturbing fact is often lubricating oil is procured on price consideration only and neglect issues such as scuffing, scoring, wet-ability etc properties.
Cost differential between normal mineral oil containing higher levels of sulphur and phosphorous in relation to vacuum distilled mineral oils is around 75-80 per cent more but the usable life of oil, if cleanliness maintained around NAS6, will justify the extra cost as life will be minimum double of normal mineral oil. A cement plant in Eastern India has continually achieved life of three times that of normal mineral oils there by not only resulting in huge savings to the organisation by way of less oil consumption and frequent shutdowns for changing oil.
Do note, normal mineral oils with higher levels of sulphur and phosphorous have an greater affinity to absorb moisture from the atmosphere leading to formation of sulphuric & phosphoric acids; both are very harmful towards life of bearings, seals and last but not least internal preservative paints applied to gearbox housing walls adding to further contamination.
A question we need to ask our self, as buyers we seek guarantee and warranty at the drop of a hat then why not for lubricants used?
Another cause of failure beyond warranty period is the upkeep of breathers, seals, etc. along with external surface of the gear drive. Often it is neglected resulting in breathers getting choked &/or become an ingress point for dirt when drive is stopped. As a result we have oil seal leakages and oil contamination leading to premature failures. Such instances are quite common in conveyor drives of cement grinding section or packing plant, coal handling conveyors, etc. An excuse we at times come across for not maintaining minimal level of cleanliness is, it is not a critical drive! The same excuse is also conveyed when the gearbox is covered with dust. What fails to be appreciated by the user is damage is taking place to investments and it can has a cascading effect.
There are numerous other instances of failures beyond warranty period but this is nether the forum or place to address these issues.
Failures during warranty period can be generally summed up under following heads as trends prevailing in gear design are to raise power levels till it does not result in a failure while decreasing volumes thus weight leading to increasing problems of heat dissipation:

Faulty or inadequacy of design
Incorrect selection & use of materials for manufacture
Incorrect selection of bearing
Manufacturing errors
Heat treatment errors
Assembly errors
Fluctuating or incorrectly defined operating parameters
Variants from original specification supplied &/or contaminates
Use of improper or incorrect quality of lubricant

Very rarely only one of the above mentioned causes account for failure to gear drives thus understanding and assessing gear damage requires in-depth knowledge of:

Gear contact patterns
Gear tooth failure types and probable causes
Bearing failure types with probable reasons
Lubricating oils
Oil flow within the gear drives be it splash or forced lubrication, etc.

It is not feasible to go through all these aspects in depth through this short article but to create awareness towards minimising risks of premature failures. We as such recommend use of following documents as a starting point to improve performance of gear drives thus overall operations of a plant. The documents relate to what needs to be communicated to the prospective seller and what in return you must get from them without fail.

Roundtable discussions focus on innovation for safer highways.

Held on 12 March 2026 at Courtyard by Marriott, Mumbai, alongside the Infrastructure Today Airport Conclave, the RAHSTA Roundtable brought together stakeholders from across the highways and infrastructure ecosystem to shape the agenda for the 16th RAHSTA 2026, scheduled for 8–9 July 2026 at the Jio Convention Centre, Mumbai. The session focused on key industry themes including road construction, technology, safety and long-term sustainability.

Opening the discussion, Pratap Padode, Founder, FIRST Construction Council, said the roundtable marked the beginning of a broader consultative process leading up to the July event. The aim, he noted, is to bring together industry stakeholders to refine the agenda for discussions on the future of roads, bridges, tunnels and allied infrastructure.

Padode noted that while central road project awards have slowed in recent years, states are increasingly driving the next phase of infrastructure growth. Maharashtra, with its long-term road development plans and agencies such as MSRDC and MSIDC, is expected to play a significant role in this expansion.

RAHSTA Expo 2026 as a specialised platform dedicated to road infrastructure, covering highways, tunnels, bridges and flyovers along with construction technologies, safety systems and maintenance solutions. He also highlighted the growing importance of rural connectivity and said the organisers are engaging with government bodies to highlight rural road development initiatives.

Tanveer Padode, CIO, ASAPP Info Group, presented insights from IMPACCT, the group’s infrastructure intelligence platform. He pointed to a strong project pipeline despite slower highway awards earlier in the year, noting that states such as Maharashtra, Odisha and Arunachal Pradesh are emerging as key drivers of new projects. The data also revealed that only a small group of contractors participates in large-value infrastructure bids.

Lt Gen Rajeev Chaudhary, former Director General, Border Roads Organisation and Chairman of the RAHSTA Expo Committee, emphasised the need for stronger collaboration across the ecosystem, including policymakers, contractors, technology providers and financiers. He also called for addressing systemic issues within the sector and encouraged greater participation of women in infrastructure leadership.

The discussion also explored the evolving economics of road development. Phani Prasad Mandalaparthy, Associate Director, CRISIL Intelligence, noted that the slowdown in project awards reflects a shift towards higher-value logistics corridors rather than simple road widening projects. However, private participation through BOT and TOT models remains limited.

From the contractors’ perspective, Sudhir Hoshing, Whole-Time Director, Ceigall, said companies are becoming more selective in bidding, favouring projects with clearer payment mechanisms and efficient processes. While NHAI continues to offer greater operational clarity, states such as Uttar Pradesh and Bihar were cited as relatively supportive environments for project execution.

Durability and sustainability also emerged as key themes. Himanshu Agarwal, COO – Road & Infrastructure, Zydex Group India, highlighted the need to prioritise lifecycle performance and resilient pavements, while participants discussed the potential of alternative materials such as plastic waste, steel slag and industrial by-products in road construction.

Dr LR Manjunatha, Vice President, JSW Cement, emphasised that India has abundant fly ash, slag and other industrial materials that can improve durability and sustainability if integrated into specifications and policy frameworks.

Technology and equipment challenges were also discussed. Dr Lakshmana Rao Mantri, Dy General Manager, Afcons Infrastructure, highlighted the shortage of tunnel boring machines (TBMs), which is delaying several underground infrastructure projects. Participants agreed that developing domestic TBM manufacturing capabilities will be critical for future infrastructure expansion.

The future of concrete pavements was another area of discussion. Dr V Ramachandra, President, Indian Concrete Institute, stressed that the debate should focus on lifecycle performance rather than material choice alone, noting that evolving design standards are improving the feasibility of concrete roads.

Prof Dharamveer Singh of IIT Bombay added that while India has made significant progress in infrastructure development, stronger capacity building and better execution practices are essential to ensure consistent road quality.

The discussion also touched upon technology adoption in the sector. Rushabh Mamania, Partner & CBO, Roadvision, highlighted the growing role of AI in road infrastructure, noting that AI-driven monitoring systems are already being deployed across large stretches of national highways.

Overall, the roundtable underscored that the future of highway infrastructure will depend not only on the pace of construction but also on durability, safety, technology integration and sustainable materials. The discussions offered valuable insights that will help shape the agenda for RAHSTA 2026 and guide future collaboration within the industry.

CTS Roundtable Maps Technology Roadmap for Construction

Ahead of the Construction Technology Show (Con Tech Show) 2026, industry leaders, technology innovators and academia came together in Mumbai to deliberate on how digitalisation, automation and industrialised construction can reshape the sector. The discussion made one thing clear: construction can no longer afford to treat technology as optional.

Held on 12 March 2026 at Courtyard by Marriott, Mumbai, alongside the Infrastructure Today Airport Conclave, the CTS Roundtable served as a precursor to the Construction Technology Show 2026, scheduled for 19–20 August 2026 at NESCO, Mumbai.

A platform to move from discussion to deployment

Opening the session, Pratap Padode, Founder and Editor-in-Chief, ASAPP Info Global Group, said construction technology has long remained close to his heart, especially given the sector’s traditionally slow pace of technology adoption. He noted that over the years, the Construction Technology Summit had steadily built interest, and the next step was now to expand it into a larger, more meaningful platform that could bring together technology providers, users, startups and innovators under one roof.

Padode said the vision for CTS is not limited to software alone. The platform aims to embrace all forms of technology that can improve construction efficiency, quality and execution—from digital tools and project management systems to lean construction, off-site fabrication and startup-led innovation. He also highlighted plans to deepen startup participation and create space for young companies to showcase emerging construction solutions.

Industry at a turning point

Moderating the roundtable, Naushad Panjwani, Chairman, Mandarus Partners, set the context by pointing out that the global construction industry, despite being a multi-trillion-dollar sector, continues to lag in productivity. He noted that while manufacturing has consistently improved efficiency, construction has remained slow to modernise.

Referring to both global and Indian trends, Panjwani underlined that the industry is now at a decisive moment. India, he said, is entering a major build cycle, and delivering the next phase of infrastructure and real estate growth through traditional methods alone is no longer viable. The goal of the roundtable, therefore, was not to debate technology in isolation, but to identify the most critical conversations that would bridge the gap between innovation and implementation.

His central message was clear: CTS 2026 must be shaped around themes that make CEOs, CIOs and CTOs feel they cannot afford to miss the event.

From BIM to AI, data to governance

A major theme that emerged through the discussion was the need for better data, better visibility and better decision-making. Dr Venkata Santosh Kumar of IIT Bombay echoed this, saying that the underlying data infrastructure itself needs attention. Construction projects, particularly remote ones, often face issues around connectivity, data collection and data use. Without this foundation, more advanced technologies cannot deliver their full value.

Chandra Vasireddy, CEO & Co-founder, Inncircles, expanded the discussion to governance, arguing that technology must help connect the many moving parts of a construction business. For him, the real value of digital transformation lies in creating better governance, clearer visibility and stronger business outcomes.

Tejas Vara of Inncircles stressed the importance of timely site data for leadership teams, especially in large and remote projects where decisions on materials, machinery and manpower often get delayed because information does not reach headquarters in time.

The role of AI also featured prominently. Rushabh Mamania, Partner and CBO, Roadvision said that while AI and machine learning are now common terms, vision intelligence and language intelligence have still not deeply penetrated the construction sector. He emphasised that startups in India are building relevant AI-led solutions and are already attracting international interest, showing that innovation need not be imported—it can be built locally and scaled globally.

Industrialised construction gains ground

The roundtable also placed strong emphasis on industrialised construction methods. Kalyan Vaidyanathan, CTO – Construction & R&D, Tvasta, called for greater focus on off-site fabrication and the broader industrialisation of construction. Bhargav Jog, General Manager, Dextra, highlighted precast technology and alternative sustainable materials as areas with immediate relevance.

Several participants agreed that modular, precast and pre-engineered approaches are no longer niche ideas. They are increasingly becoming practical responses to the sector’s challenges around labour shortage, timelines, quality control and predictability.

Anup Mathew, Sr VP & Business Head, Godrej, argued that the industry needs a fully integrated approach—from design and procurement to execution and asset management. Unless these are connected, technology adoption will remain fragmented and sub-optimal. He pointed to pre-engineered and modular systems as examples of how industrial thinking can compress timelines, improve quality and reduce dependence on difficult on-site conditions.

Adoption remains the biggest hurdle

While there was broad agreement on the promise of technology, the discussion repeatedly returned to one fundamental challenge: adoption.

Abhishek Kumar, COO, LivSYT, observed that the market is crowded with solutions, but many buyers still struggle to evaluate which technology suits which use case. According to him, the industry needs clearer frameworks to help users select, compare and adopt solutions, rather than expecting a single platform to solve every problem.

Dr Tenepalli JaiSai, Associate Professor, School of Construction(SoC), NICMAR University, noted that isolated technologies will not solve the productivity problem by themselves. What is required is an integrated Construction 4.0 approach, where digital, physical and cyber-physical systems work together rather than in silos.

That concern around silos was reinforced by Subodh Dixit, former Director, Shapoorji Pallonji, who said the issue is not just that technologies are disconnected, but that stakeholders are as well. Clients, consultants, contractors and partners often operate with different priorities. Unless these silos are broken, technology will struggle to percolate across the full project value chain.

Harleen Oberoi, Project Management, Tata Realty shared a practical perspective from the client side, saying that successful BIM implementation requires investment across the ecosystem, not just within one organisation. Trade partners, vendors and other stakeholders must also be trained and aligned if the technology is to deliver its intended results.

Beyond buzzwords

A notable takeaway from the session was that the industry is moving past the phase of treating technology as a buzzword. Participants repeatedly stressed that the real question is not whether technology should be used, but where it creates measurable value and how that value can be scaled.

The conversation also expanded beyond mainstream themes to include repairs and rehabilitation, construction and demolition waste, sustainability, circular economy, green sourcing, carbon measurement, design interoperability, generative design, robotics, and the role of horticulture and greener built environments.

Setting the agenda for CTS 2026

By the close of the session, the roundtable had surfaced a strong set of themes for the upcoming show: BIM and digital twins, AI and data platforms, industrialised construction, startup innovation, governance-led technology adoption, robotics, sustainable materials, and integrated project delivery.

More importantly, the session established CTS 2026 as more than an exhibition. It is shaping up to be a serious industry platform where users, technology providers, researchers and policymakers can collectively define the future of construction.

As Padode noted in his closing remarks, the conversation will continue through further consultations and possibly webinars in the run-up to the show. If the roundtable is any indication, CTS 2026 will aim not merely to showcase technology, but to push the industry towards meaningful adoption at scale.

SEEPEX introduces BN pumps with Smart Joint Access (SJA) to improve efficiency, reliability, and inspection speed in demanding rock blasting operations.
Designed for abrasive and chemical media, the solution supports precise dosing, reduced downtime, and enhanced operational safety.

SEEPEX has introduced BN pumps with Smart Joint Access (SJA), engineered for the reliable and precise transfer of abrasive, corrosive, and chemical media in mining and construction. Designed for rock blasting, the pump features a large inspection opening for quick joint checks, a compact footprint for mobile or skid-mounted installations, and flexible drive and material options for consistent performance and uptime.

“Operators can inspect joints quickly and rely on precise pumping of shear-sensitive and abrasive emulsions,” said Magalie Levray, Global Business Development Manager Mining at SEEPEX. “This is particularly critical in rock blasting, where every borehole counts for productivity.” Industry Context

Rock blasting is essential for extracting hard rock and shaping safe excavation profiles in mining and construction. Accurate and consistent loading of explosive emulsions ensures controlled fragmentation, protects personnel, and maximizes productivity. Even minor deviations in pumping can cause delays or reduce product quality. BN pumps with SJA support routine maintenance and pre-operation checks by allowing fast verification of joint integrity, enabling more efficient operations.

Always Inspection Ready

Smart Joint Access is designed for inspection-friendly operations. The large inspection opening in the suction housing provides direct access to both joints, enabling rapid pre-operation checks while maintaining high operational reliability. Technicians can assess joint condition quickly, supporting continuous, reliable operation.

Key Features

Compact Footprint: Fits truck-mounted mobile units, skid-mounted systems, and factory installations.
Flexible Drive Options: Compact hydraulic drive or electric drive configurations.
Hydraulic Efficiency: Low-displacement design reduces oil requirements and supports low total cost of ownership.
Equal Wall Stator Design: Ensures high-pressure performance in a compact footprint.
Material Flexibility: Stainless steel or steel housings, chrome-plated rotors, and stators in NBR, EPDM, or FKM.

Operators benefit from shorter inspection cycles, reliable dosing, seamless integration, and fast delivery through framework agreements, helping to maintain uptime in critical rock blasting processes.

Applications – Optimized for Rock Blasting

BN pumps with SJA are designed for mining, tunneling, quarrying, civil works, dam construction, and other sectors requiring precise handling of abrasive or chemical media. They provide robust performance while enabling fast, reliable inspection and maintenance.With SJA, operators can quickly access both joints without disassembly, ensuring emulsions are transferred accurately and consistently. This reduces downtime, preserves product integrity, and supports uniform dosing across multiple bore holes.

With the Smart Joint Access inspection opening, operators can quickly access and assess the condition of both joints without disassembly, enabling immediate verification of pump readiness prior to blast hole loading. This allows operators to confirm that emulsions are transferred accurately and consistently, protecting personnel, minimizing product degradation, and maintaining uniform dosing across multiple bore holes.

The combination of equal wall stator design, compact integration, flexible drives, and progressive cavity pump technology ensures continuous, reliable operation even in space-limited, high-pressure environments.

From Inspection to Operation

A leading explosives provider implemented BN pumps with SJA in open pit and underground operations. By replacing legacy pumps, inspection cycles were significantly shortened, allowing crews to complete pre-operation checks and return mobile units to productive work faster. Direct joint access through SJA enabled immediate verification, consistent emulsion dosing, and reduced downtime caused by joint-related deviations.

“The inspection opening gives immediate confidence that each joint is secure before proceeding to bore holes,” said a site technician. “It allows us to act quickly, keeping blasting schedules on track.”

Framework agreements ensured rapid pump supply and minimal downtime, supporting multi-site operations across continents
