Akhilesh Satre discusses smart vertical transport with predictive diagnostics, real-time monitoring and robust safety engineering for measurable gains in uptime and workforce protection.

Vertical transportation at any cement plant is a crucial component of daily operations, from material carrying to worker transport. With the growing industrialisation and urbanisation, cement plant production is at a high pace, leading to the high-volume use of elevators for continuous work. This sudden growth needs advanced and new digital capabilities that make safe, seamless and efficient vertical transportation, not just an elevator to transfer material from one point to another.
With Industry 4.0 adoption, India’s cement sector is shifting gears to focus not just on production capacity but also on efficiency and safety in operations. Modern cement plants are specific systems wherein each part, like conveyors and crushers, is integrated and works together. Thus, vertical movement is already more than just supporting infrastructure in such surroundings.
For decades, Industrial elevators used to be perceived only as elevators for goods or people moving between different floors. Nowadays, without a doubt, elevators have become intelligent systems contributing to increased productivity, efficiency, and safety, reducing downtime, and integrating with digital plant management platforms. Avinyatech Elevators believes that smart elevators are an integral part of smart manufacturing facilities.

Vertical transportation: An important link in plants
Cement production is composed of a series of processes that require passing through different
levels of production, including raw material preparation, clinker production, packaging process, and maintenance process.
Cement plants work under quite tough conditions, unlike other commercial plants, such as:
• Continuous 24×7 operations
• Vibration and corrosive atmosphere
• Heavy equipment movement
• High temperatures
• Vibrations and corrosive environments
• Frequent maintenance works
Traditional elevator systems frequently meet challenges in these tough working conditions, resulting in higher service demands and unplanned outages. For this reason, industrial elevators working in such environments are required to provide durability, dependability, and safety while allowing smooth running of the plant.

Smart elevators: More than vertical mobility
The smart elevator idea is based on much more than simply automating control or increasing speed. Smart industrial elevators are competent devices
that can interact with the building or plant control systems, monitor their performance, and provide for maintenance planning.

Modern smart elevators are equipped with technologies such as:
• Internet of things (IoT) monitoring for providing real-time information on equipment health
• Sensor diagnostics for predictive maintenance
• Remote diagnostic and alarm systems
• Smart energy management
• Access control systems
• Automatic emergency communication systems
• Data logging for maintenance planning and compliance
All these features allow plant managers to diagnose potential problems in advance, preventing unplanned stops and service costs. In the industry where every minute of downtime can affect production efficiency, predictive maintenance is one of the key benefits of intelligent elevator systems.

Designing elevators for harsh industrial environments
Elevators utilised in cement factories must be designed differently from regular elevators. Everything that has to be used should be able to work under difficult and harsh conditions.
Some of the main elements in constructing industrial elevators include:
• Dust-proof electric systems
• Strong rails and support systems
• Resistant coatings
• Reinforced cabins
• Effective ventilation systems
• High loading capacity
• Rescue equipment
• Sufficient performance despite vibrations and temperature fluctuations

Lift systems such as material lifts differ in their functions and should not be developed in accordance with any standardised solutions. Selecting the right elevator begins with understanding the plant’s workflow rather than merely calculating travel height or load capacity.

Safety: The foundation of vertical transport systems
No discussion of industrial lifts would be complete without emphasising safety. Cement plants feature heavy machinery, high platforms, tight spaces and constant movement of people and materials. Therefore, safety must be a priority in every lift installation, in design, installation, operation and maintenance.

Modern industrial lifts include several safety features such as:
• Overspeed governors monitor elevator speed
and activate a safety system if the elevator’s
speed varies.
• Automatic braking systems prevent hazardous accidents by applying the brakes in any unsafe conditions.
• Door interlocks prevent elevators from operating unless all doors are closed.
• Emergency lowering systems
• Overload protection
• Backup power support to assist in rescue operations
• Fire-retardant wiring and components
• Alarm and communication systems
Safety is not achieved through technology alone. It also requires proper installation, periodic inspection, preventive maintenance, operator awareness and strict adherence to operating procedures.

The development of smart monitoring
One of the most significant advancements in the field of industrial elevators is that it has evolved from being reactive to being predictive in its maintenance philosophy. Traditional maintenance schedules are often determined according to fixed intervals, irrespective of the usage of the appliance. In contrast, smart maintenance continuously monitors operating parameters such as motor parameters, brake wear, vibration levels, the number of times the door is opened and closed, etc. Upon detecting an abnormality in one of the above-mentioned parameters, maintenance teams are alerted before a failure occurs.
In the cement industry, this means:
• Decreased production downtimes
• Lower costs of maintenance during the whole period of an equipment’s life
• Better availability of equipment when needed
• Improvement of maintenance planning
• Better safety of the employees
Access to real-time performance of equipment allows the operators to optimise the use of the equipment and increase the efficiency of the operation process.

Indian standards and regulations
India has made tremendous progress in the safety norms of lifts in the last decade. Although lift legislation is still determined by state lift acts, industrial installations are increasingly expected to conform to recognised national and international standards.
Manufacturers and project developers must meet:
• National Building Code (NBC) of India applicable provisions for industrial buildings
• Lifts and escalators specifications of the Bureau of Indian Standards (BIS)
• Electrical safety standards
• Fire safety standards prescribed by local authorities
• Industrial workplace occupational safety standards
The plant safety management systems shall also include periodic inspections, maintenance records and testing of safety devices. Compliance is never simply a regulatory requirement. It’s an investment in operational reliability and in protecting your workforce.

Common causes of elevator accidents in industrial plants
Yet, even with all the technological advancements, accidents do happen with industrial lifts. Most investigations reveal that the root causes are not equipment failures, but operational negligence.
Contributing factors that are common are:
• Poor preventive maintenance practices
• Deferred replacement of worn-out parts
• Elevator overloading
• Unauthorised amendments
• Inadequate operator training
• Failure to conduct routine inspections
• Failure to follow warning alarms or fault indications
• Lack of emergency preparedness
• Installation by unauthorised agencies
• No yearly safety audits
There are many accidents out there that are
100 per cent preventable if organisations foster a proactive safety culture, supported by competent maintenance partners.

Key considerations for cement plants
Plant owners need to consider more than the initial procurement cost when choosing or upgrading lift systems.
Points to Consider:
• Suitability for dusty and high-temperature environments
• Required capacity and frequency of operation
• Service friendly
• Spare parts availability
• Remote monitoring ability
• Adherence to relevant standards
• Energy performance
• Features for emergency evacuation
• Life cycle operating cost
• Service network and technical service
Investing in high-quality vertical transportation systems is investing in long-term value with less downtime, safer operation and more continuity
of operation.

The road ahead
The development of smart manufacturing is transforming the future of elevator technologies as it will establish new systems that become integral parts of the industrial world. The introduction of artificial intelligence and machine learning will undoubtedly make communication and smart analysis more effective and thus improve equipment management and energy efficiency.
We understand that modern manufacturing requires modern ways of moving people and goods. The proper combination of advanced technology with innovative implementation in both compliant and safe elevator systems make them pivotal in achieving high production levels and safety in the industry.
Looking ahead, India’s cement industry will be shaped by smart technology as plants will become equipped with advanced and efficient vertical movement methods.

Sujeet Kumar Singh, Founder, HSESkillEdge, discusses the evolution of a technology-enabled safety ecosystem, backed by visible leadership, which is changing the way cement manufacturers are perceiving safety norms.

Preventable incidents continue to occur in cement plants that have invested heavily in safety systems and PPE. Sujeet Kumar Singh, Founder of HSESkillEdge, lists down complacency, normalisation of deviations and a compliance mindset as part of the challenge. In this interview, he maps the full spectrum of digital safety technologies that are currently transforming risk management within cement plants.

How is the definition of safety in the cement industry evolving from regulatory compliance to a strategic driver of operational excellence?
From an Occupational Health and Safety (OH&S) perspective, safety in the cement industry has transformed from a compliance-driven function focused on accident prevention into a strategic, risk-based management system that protects people while driving operational excellence and supporting ‘Net Carbon Zero’ goals.
Modern cement plants are increasingly adopting artificial intelligence (AI), industrial internet of things (IIoT), virtual reality (VR), training simulators, geofencing, geotagging, GPS-enabled vehicle safety systems, wearable technologies, drones, robotics and predictive analytics to proactively identify hazards, monitor critical risks, and improve worker health and safety. AI-powered video analytics detect unsafe acts and PPE non-compliance in real time and generate audio alarm, while wearable devices monitor fatigue, heat stress and physiological parameters.
Predictive maintenance minimises the risk of catastrophic equipment failures, and drones and robotic inspection systems eliminate the need for personnel to enter hazardous areas such as kilns, silos, preheaters and confined spaces. Advanced AI-based process optimisation enhances combustion efficiency, reduces dust and greenhouse gas emissions, improves energy efficiency and lowers workers’ exposure to hazardous pollutants.
By integrating digital technologies with strong safety leadership, occupational health management, and a proactive safety culture, the cement industry is creating safer, healthier and more sustainable workplaces that enhance operational reliability while accelerating the journey toward ‘Zero Harm and Net Carbon Zero’.

With increasing automation and digitalisation, how can cement companies ensure that technology strengthens rather than replaces a strong safety culture?
Increasing automation and digitalisation should strengthen, not replace, a strong safety culture. Technologies such as AI, IIoT, wearable devices, drones, and digital Permit-to-Work systems help identify hazards, predict failures, and reduce worker exposure to risks. However, sustainable safety performance depends on a top-down commitment through Visible Felt Leadership (VFL) and a bottom-up approach that actively engages employees in hazard identification, risk assessment, and continuous improvement.
By integrating advanced technologies with strong leadership, workforce participation, competency development and human oversight, cement companies can build a resilient safety culture that supports Zero Harm, operational excellence, and Net Carbon Zero.

Which emerging technologies-from IoT and AI to digital permit-to-work systems-are creating the biggest impact on risk prevention in cement plants?
Advanced digital technologies enable proactive hazard identification and predictive risk management, significantly reducing worker exposure to hazardous environments while improving compliance with Permit-to-Work (PTW), Lockout/Tagout (LOTO), and other critical risk controls. They provide early detection of equipment failures, fires, and occupational health hazards through continuous monitoring, while robotics, drones, and remote inspection systems make maintenance safer by minimising human intervention in high-risk areas.
By reducing human error, enhancing emergency response, and improving asset reliability and operational efficiency, these technologies accelerate the cement industry’s journey toward Zero Harm, Operational Excellence, Industry 4.0, and Net Carbon Zero.

Despite significant investments in safety systems and PPE, why do preventable incidents still occur, and what fundamental shift is needed?
Despite significant investments in safety systems, PPE and digital technologies, preventable incidents continue to occur because most are driven by human factors, weak safety culture, and inconsistent implementation of critical risk controls rather than the absence of procedures or equipment. Common causes include complacency, normalisation of deviations, inadequate supervision, poor risk perception, ineffective communication, production pressure and failure to learn from near misses.
The fundamental shift required is from compliance-based safety to a culture of ownership and operational discipline, where Visible Felt Leadership (top-down commitment) is combined with active workforce participation (bottom-up engagement). Safety should become a core organisational value, supported by predictive technologies, continuous learning and accountability, so that every employee proactively identifies, reports and controls risks, before they lead to incidents, enabling the journey toward Zero Harm.

How can cement companies build a safety culture where contractors, frontline workers and leadership share equal ownership of safety outcomes?
Cement companies can build a shared safety culture by making safety a collective responsibility rather than a management function. This requires a top-down approach through Visible Felt Leadership (VFL), where leaders demonstrate commitment by regularly engaging with frontline teams, and a bottom-up approach that empowers employees and contractors to identify hazards, stop unsafe work, report near misses and participate in risk assessments.
Contractors should be held to the same safety standards, competency requirements, and performance expectations as permanent employees through robust onboarding, digital contractor management, and continuous training.
By fostering trust, open communication, recognition of safe behaviours, and accountability at every level, supported by digital tools such as AI, IIoT and digital PTW systems, cement companies can create a culture where everyone owns safety, every task is performed safely, and every incident is preventable, driving the journey toward Zero Harm.

As alternative fuels, waste co-processing and decarbonisation reshape cement manufacturing, what new safety challenges should the industry prepare for?
As cement plants adopt alternative fuels, waste co-processing and decarbonisation technologies, they face new safety challenges, including fire and dust explosion risks, toxic and flammable gas exposure, biohazards, preheater blockages, hot material blowouts and process instability. Managing these evolving risks requires advanced engineering controls, AI, IIoT sensors, thermal imaging, smart gas monitoring, robotics and predictive analytics, supported by ATEX-compliant designs, automated fire protection, enhanced PPE, competency-based training and robust process safety management.

Advanced PPE and Competency Heat stress, burns, toxic exposure, biohazards Aluminised heat suits, chemical-resistant PPE, PAPR respirators, cut-resistant gloves, competency-based training and emergency preparedness

What will distinguish the safest cement plants of the future from those that simply meet compliance requirements?
The safest cement plants of the future will move beyond reactive compliance to predictive, technology-enabled safety ecosystems that prevent incidents before they occur. Industry leaders will eliminate worker exposure to high-risk tasks through automation, robotics, drones, and AI, while using predictive analytics, AI-enabled vision systems, connected smart PPE, digital LOTO and real-time health and environmental monitoring to proactively manage risks.
Safety will extend beyond the plant through contractor and logistics safety integration, ensuring the same high standards across the entire value chain. By combining advanced technologies with strong leadership and a proactive safety culture, future-ready cement plants will achieve Zero Harm, operational excellence and sustainable manufacturing.

Gautam Sinha, Vice President, Sales & Marketing, Process Industries, ABB India, on the changing role of automation from a productivity tool to a cohesive operating ecosystem.

The conversation around automation in cement has shifted. It is no longer about replacing manual tasks or improving line efficiency. It is about building plants that learn, adapt and self-optimise in real time. In this interview, Gautam Sinha, Vice President, Sales & Marketing, Process Industries, ABB India, explains how predictive intelligence is solving problems that have resisted the industry for decades. He underscores the importance of cybersecurity, electrification and carbon capture as components of a single transformation that the cement industry can no longer afford to sequence.

How is automation evolving from a productivity tool to a strategic enabler of sustainability, resilience and profitability in the cement industry?
The cement industry is witnessing a shift where automation is no longer viewed solely as a productivity tool, but as a strategic enabler of sustainability, resilience, and profitability. By integrating various operational areas and leveraging advanced technologies, companies are better equipped to address key industry challenges. This integration allows for the promotion of higher usage of alternative and renewable energy sources and the real-time optimisation of asset performance, which are crucial for sustainability.
Digitalisation and automation are key to reaching environmental sustainability targets, not just by reducing emissions but also by optimising energy consumption and management. This creates immediate benefits for operating costs and margins, enabling new business models for high-tech, low-CO2 cements. For example, advanced process control (APC) solutions can improve SO2 emissions control while reducing hydrate consumption, directly impacting both environmental performance and profitability.
Furthermore, predictive asset models can help cement plants manage operations remotely, ensuring business continuity. By predicting asset failures and optimising maintenance schedules, automation minimises downtime and reduces one of the biggest costs in cement plants, thereby boosting profitability.

As cement plants accelerate digital transformation, which technologies do you believe will deliver the next breakthrough in operational performance?
As cement plants accelerate their digital transformation, several technologies are poised to deliver the next breakthrough in operational performance. Artificial Intelligence (AI) and Machine Learning (ML) are at the forefront of this transformation. These technologies enable advanced data analytics and smart optimisation, from raw materials to dispatch, which is a game-changer for many cement producers. To fully leverage these insights, robust data management systems like Knowledge Manager (KM) solutions, are essential, as they consolidate plant-wide data to connect equipment, processes, and personnel to an unprecedented. This unified intelligence creates a single source of truth, making the concept of a highly efficient, autonomous plant an achievable reality.
The concept of an autonomous plant is becoming a reality through the use of digital and automation technologies that connect equipment, processes, and people to an unprecedented degree. By learning from a plant’s historical energy usage and production schedules, these forecasting tools deliver accurate predictions that help plants reduce peak demand charges on electricity bills. Technologies such as ABB Ability™ Knowledge Manager and Expert Optimiser are already helping cement plant owners achieve business results and meet decarbonisation targets. For example, ABB Ability™ Expert Optimizer for cement helps to optimise operations and reduce energy consumption.
Significant developments are also emerging from technologies that enable process electrification, fundamentally changing how cement is produced. Innovations in electrically powered heating solutions for high-temperature processes like clinkerisation, and the use of electric plasma to replace fossil fuels in calcination, offer pathways to production with lower emissions. When combined with essential technologies like Carbon Capture, Utilisation, and Storage (CCUS), these electrification strategies are a critical part of the plan for the future of the cement industry.

With AI becoming integral to industrial operations, how do you see predictive intelligence reshaping process control, quality assurance and energy optimisation in cement manufacturing?
AI-powered solutions gather data from multiple sources like smart sensors and databases to enable algorithms to evolve and improve their predictions. In process control, AI is moving traditional Advanced Process Control (APC) solutions towards adaptive APC. While traditional APC addresses thermal efficiency and fuel switching, AI-driven analytics will enable automatic re-modeling and tuning, optimising additional variables and allowing systems to operate at peak performance. In the future, AI systems will interact with control system history data to learn from patterns, recommend optimal parameters, and even write new setpoints directly to the control system.
For quality assurance, AI is solving longstanding challenges like cement quality prediction. Traditionally, cement strength is measured after 28 days, which is too late for process corrections. ABB is leveraging ML with data-driven soft sensors to predict 28-day strength on the day of sampling, allowing for immediate process adjustments and reducing the need to ‘overdeliver’ on product specifications. In energy optimisation, AI-based anomaly detection can learn a plant’s “normal” energy usage patterns and use adaptive setpoints to detect unusual behavior. By triggering alerts on energy consumption deviations, operators no longer need to set manual setpoints or deal with notification overload. The system can also learn from a plant’s energy
usage and production schedules to deliver accurate forecasts, helping to reduce peak demand charges on electricity bills.

Cybersecurity is becoming inseparable from automation; how should cement manufacturers strengthen digital resilience while expanding connected operations?
As automation and digitalisation become more integrated into cement manufacturing, building
strong digital resilience is crucial. To achieve this
while expanding connected operations, cement manufacturers should adopt a proactive and AI-driven approach to cybersecurity.
Strengthening digital resilience involves several key strategies. Manufacturers can leverage AI-powered analytics solutions to continuously monitor, diagnose, and resolve security issues, which helps in safeguarding personnel, protecting assets, and preserving the company’s reputation. Given the unpredictable and evolving nature of both technology and cyber threats, it is essential to periodically review and update security strategies. This includes conducting simulations for various threat scenarios, such as a major ransomware attack, to test the robustness of the defense systems. Furthermore, data analytics can be employed to run “what-if” scenarios, allowing plants to anticipate potential vulnerabilities and fortify their digital infrastructure accordingly. This forward-thinking, analytical approach enables cement producers to not only connect their operations but also secure them effectively against the dynamic landscape of cyber threats.

What will define the ‘cement plant of the future,’ and what role will companies like ABB play in enabling that transformation?
The cement plant of the future is defined by the seamless integration of digitalisation, automation, electrification, and decarbonisation. Operating as a highly connected, increasingly autonomous ecosystem, it relies on real-time data integration, digital twins, and remote monitoring to run processes on “autopilot”. Crucially, the future plant is deeply sustainable—minimising its carbon footprint through the adoption of alternative fuels, electrified high-temperature processes, and carbon capture technologies.
ABB plays a pivotal role in this transformation by providing the essential automation, digital infrastructure, and electrification technologies. Through tools like ABB Ability™ Expert Optimizer and Knowledge Manager, ABB uses AI, neural networks, and model predictive control to stabilise kiln operations, optimise energy consumption, and maximise alternative fuel usage. Additionally, ABB secures these highly connected environments with proactive, AI-driven cybersecurity, while pioneering sustainable innovations like Electric Arc Calcination to help manufacturers transition to net-zero, highly resilient digital operations.
