Engineering safer conveyors: Art meets science
Published

All new conveyor systems will inevitably succumb to the punishing bulk handling environment and begin the slow process of degradation. The system will eventually require more time and labor for maintenance, shorter spans between outages, longer periods of downtime, and an ever-increasing cost of operation. This period is also accompanied by an increased chance of injury or fatality as workers are progressively exposed to the equipment to perform cleaning, maintenance and to fabricate short-term fixes to long-term problems. A total system replacement is cost- prohibitive, but to remain compliant and/or meet ever-increasing production demands, upgrades and repairs are unavoidable.
When examining the safety of a system, improving efficiency and reducing risk can be achieved by utilizing a hierarchy of control methods for alleviating hazards. The consensus among safety professionals is that the most effective way to mitigate risks is to design the hazard out of the component or system. This usually requires a greater initial capital investment than short-term fixes, but yields more cost-effective and durable results.
Science: Hierarchy of control methods
Examining the US Occupational Safety and Health Administration (OSHA) accident database reveals the dangers of working around conveyors.[1] Studies have revealed that the highest prevalence of accidents is near locations where cleaning and maintenance activities most frequently take place: take-up pulley, tail pulley, and head pulley.
Designs should be forward-thinking, exceeding compliance standards and enhancing operators??ability to incorporate future upgrades cost-effectively and easily by taking a modular approach. Designing hazards out of the system means alleviating causes with the intent to bolster safety on a conveyor system, but the methods of protecting workers can vary greatly.
In many cases, it will be necessary to use more than one control method, by incorporating lower-ranked controls. However, these lower-ranking approaches are best considered as support measures, rather than solutions in and of themselves.
PPE includes respirators, safety goggles, blast shields, hard hats, hearing protectors, gloves, face shields, and footwear, providing a barrier between the wearer and the hazard. Downsides are that they can be worn improperly, may be uncomfortable to use through an entire shift, can be difficult to monitor and offer a false sense of security. But the bottom line is that they do not address the source of the problem.
Administrative controls (changes to the way people work) create a policy that articulates a commitment to safety, but written guidelines can be easily shelved and forgotten. These controls can be taken a step further by establishing ??ctive??procedures to minimise the risks. For example, supervisors can schedule shifts that limit exposure and require more training for personnel, but these positive steps still do not remove the exposure and causes of hazards.
Warning Signage is generally required by law, so this is less of a method than a compliance issue. It should be posted in plain sight, clearly understood and washed when dirty or replaced when faded. Like most lower-tier methods, signs do not remove the hazard and are easily ignored.
Installing systems such as engineering controls that allow remote monitoring and control of equipment??r guards such as gates and inspection doors that obstruct access??reatly reduce exposure, but again, do not remove the hazard.
Using the substitute method replaces something that produces a hazard with a piece of equipment or change in material that eliminates the hazard. For example, the manual clearing of a clogged hopper could be replaced by installing remotely triggered air cannons.
Examples of eliminate by design are longer, taller, and tightly sealed loading chutes to control dust and spillage or heavy-duty primary and secondary cleaners to minimize carryback. By using hazard identification and risk-assessment methods early in the design process, engineers can create the safest, most efficient system for space, budget, and application.
Economic analysis of prevention through design (PtD)
Another way of saying ??liminate by design??is PtD (Prevention through Design), the term used by The National Institute of Occupational Safety and Health (NIOSH). As a department of the U.S. Centers for Disease Control (CDC), the organisation spearheaded the PtD initiative.[3] In its report, the Institute points out that, while the underlying causes vary, studies of workplace accidents implicate ??ystem design??in 37 per cent of job-related fatalities.
Cost is most often the main inhibitor to PtD, which is why it?? best to implement safer designs in the planning and initial construction stages, rather than retrofitting the system later. The added engineering cost of PtD is often less than an additional 10 per cent of engineering but has enormous benefits in improved safety and increased productivity.
The cost of PtD initiatives after initial construction can be three to five times as much as when the improvement is incorporated in the design stage. The biggest cause of expensive retroactive improvements is cutting corners initially by seeking the lowest-bid contracts.
Low-bid process and lifecycle cost
Although the policy is generally not explicitly stated by companies, the low-bid process is usually an implied rule that is baked into a company?? culture. It encourages bidders to follow a belt conveyor design methodology that is based on getting the maximum load on the conveyor belt and the minimum compliance with regulations using the lowest price materials, components, and manufacturing processes available.
But when companies buy on price, the benefits are often short-lived, and costs increase over time, eventually resulting in losses. In contrast, when purchases are made based on lowest long-term cost (lifecycle cost), benefits usually continue to accrue and costs are lower, resulting in net savings over time.??sup>[4]
The Art: Design Hierarchy
Rather than meeting minimum compliance standards, the conveyor system should exceed all code, safety, and regulatory requirements using global best practices. By designing the system to minimize risk and the escape and accumulation of fugitive material, the workplace is made safer and the equipment is easier to maintain.
Life cycle costing should play into all component decisions. Buying on lifecycle cost and anticipating the future use of problem-solving components in the basic configuration of the conveyor provides improved safety and access, without increasing the structural steel requirements or significantly increasing the overall price. It also raises the possibility for easier system upgrades in the future.
Best practices: The ??a href=’https://indiancementreview.quintype.com/story/5985400b-6cad-4420-a931-43741b043db2’>Evolved Basic Conveyor??/strong>
Using the hierarchy of controls along with the design hierarchy, engineers will be able to construct an ??volved basic conveyor??that meets the needs of modern production and safety demands. Built competitively with a few modifications in critical areas, an evolved basic conveyor is a standard bulk material handling conveyor designed to allow easy retrofitting of new components that improve operation and safety, solving or preventing common maintenance problems.
Installing or providing maintenance-minded solutions in the loading zone can greatly improve safety and reduce man-hours and downtime. These components include slide-in/slide-out idlers, impact cradles and support cradles. On larger conveyors, maintenance aids such as overhead monorails or jib cranes assist in the movement and replacement of components. Also, designers should ensure adequate access to utilities??ypically electricity and/or compressed air??o facilitate maintenance and performance. Next-generation conveyor designs may even feature a specially-engineered idler capped with an independent power generator that uses the conveyor?? movement to generate power for a wide array of autonomous equipment.
Dust, spillage, and belt tracking are top concerns for many safety professionals. Field tests have shown that enlarged skirtboards and engineered settling zones promote dust settling, and reduce fugitive material. Curved loading and discharge chutes control the cargo transfer for centered placement and reduced turbulence. As the load is centered on the belt, guides ensure even travel through the takeup to promote consistent belt tracking.
Any transfer point is prone to buildup and clogging under the right conditions, be it ambient humidity, material wetness, volume or surface grade. Flow aids such as vibrators or air cannons on chutes can sustain the material movement, improve equipment life and reduced the safety hazards associated with manually clearing clogs.
Conclusion
Engineering safer conveyors is a long-term strategy. Although design absorbs less than 10 percent of the total budget of a project, additional upfront engineering and applying a life cycle-cost methodology to the selection and purchase of conveyor components proves beneficial.
By encouraging the use of the hierarchy of controls at the planning stage, along with the design hierarchy at the design stage, the system will likely meet the demands of modern production and safety regulations, with a longer operational life, fewer stoppages, and a lower cost of operation.

ABB reconditions 25 drives at ACC’s Jamul cement plant, avoiding 16 tonnes of CO₂ emissions while improving reliability through predictive maintenance.
Chhattisgarh
ABB has signed a multi-year Motion OneCare service agreement with ACC Limited, part of the Adani Group, to modernise ageing industrial drives at its Jamul cement plant in Chhattisgarh, improving operational reliability while avoiding approximately 16 tonnes of carbon dioxide (CO₂) emissions without disrupting production.
Announced on 27 October 2026, the agreement combines scheduled drive reconditioning, digital condition monitoring and energy appraisals to extend equipment lifespan, improve plant uptime and optimise maintenance costs. The initiative marks a shift from conventional equipment replacement towards a more resource-efficient approach to industrial asset management.
The first phase, completed in April 2026, involved the on-site reconditioning of 25 ABB ACS800 variable speed drives without a major plant shutdown. By retaining the existing cabinets and restoring the drive modules rather than replacing entire panels, ABB helped ACC preserve capital investment, minimise material consumption and avoid approximately 16 tonnes of CO₂ emissions.
A second phase, covering an additional 25 ACS800 drive modules, is scheduled for the fourth quarter of 2026. The programme is designed to improve long-term equipment reliability while allowing maintenance activities to be aligned with the plant’s operational schedules.
The ACS800 drives, installed at Jamul in 2010, had delivered more than a decade of near-continuous service in demanding cement manufacturing conditions. However, ageing electrical components and changing fault patterns had begun to affect their ability to meet the plant’s reliability requirements.
Rather than opting for complete equipment replacement, ACC engaged ABB’s certified engineers to conduct a comprehensive asset health assessment. The evaluation found that the existing cabinets and enclosures remained structurally sound, making targeted reconditioning a technically viable and cost-effective alternative to full replacement.
Drawing on nearly two decades of experience with ACC’s equipment and operating requirements, ABB developed a maintenance framework tailored to the plant’s shutdown windows, budget cycles and production priorities.
The Motion OneCare agreement incorporates planned equipment restoration, condition-based monitoring and energy assessments, enabling ACC to adopt a more systematic approach to maintaining critical electrical infrastructure.
As part of the programme, ACC has implemented ABB Ability™ Digital Powertrain Insights to monitor drive performance and identify emerging operational issues before they result in equipment failures.
The digital platform provides continuous visibility into parameters such as temperature, current, vibration and fault patterns. These insights allow maintenance teams to detect early signs of equipment deterioration, schedule interventions more effectively and reduce the likelihood of unexpected downtime.
Amit Gupta, Local Division Manager, Motion Services, ABB India, said: “We know what unchecked wear costs over time: a small inefficiency that eats away at ROI for years. At Jamul, the evidence pointed clearly to assets with productive life still in them.”
“Our job was to restore them properly and give the team the tools to stay ahead of the next problem. At ABB, we don’t just fix what fails. We want to protect what works.”
The initiative also demonstrates the growing relevance of circular economy principles in cement manufacturing, where extending the service life of existing industrial equipment can reduce capital expenditure, material consumption and the environmental impact associated with manufacturing replacement components.
According to ABB, drive reconditioning can reduce lifecycle emissions by 50 to 80 per cent compared with complete equipment replacement. By preserving functional components and restoring critical modules, the process helps retain the economic and material value of existing industrial assets.
The addition of energy appraisals in subsequent phases will further expand the programme beyond equipment restoration, enabling ACC to assess drive performance, identify energy-saving opportunities and improve operating efficiency.
For cement manufacturers, variable speed drives play an important role in controlling motors and optimising energy consumption across production processes. Maintaining their reliability and efficiency is essential for minimising operational disruptions and managing electricity costs.
Vinod Bahety, CEO – Cement Business, Adani Group, said: “Moving from reactive firefighting to a structured maintenance plan was exactly what this operation needed. That kind of peace of mind doesn’t come easily. It comes from a partner that understands how your business runs.”
“We didn’t need a full system overhaul; we needed expert support, actionable insights, and a plan we could execute around our schedule. That’s what we got.”
The project supports ACC’s broader strategy to improve manufacturing efficiency through digital transformation, preventive maintenance and sustainable asset management.
ACC, a subsidiary of Ambuja Cements and part of the Adani Group, operates 20 cement manufacturing facilities and 119 ready-mix concrete plants across India. The company has been advancing initiatives focused on renewable energy, circular economy practices and technology-driven operational improvements.
Alongside Ambuja Cements, ACC is part of a large-scale building materials business committed to achieving net-zero emissions by 2050, with near-term and net-zero targets validated by the Science Based Targets initiative (SBTi).
The Jamul initiative aligns with these sustainability objectives by demonstrating how equipment life extension and digital monitoring can contribute to resource efficiency without requiring large-scale replacement of existing infrastructure.
ABB, a global technology company specialising in electrification and automation, brings more than 140 years of industrial expertise and employs approximately 110,000 people worldwide. Its Motion Services business supports industrial customers through equipment maintenance, modernisation, digital monitoring and lifecycle management solutions.
The agreement also reflects a wider shift in industrial maintenance practices, with manufacturers increasingly adopting predictive technologies to improve equipment availability, manage costs and reduce unplanned shutdowns.
With 25 drives already reconditioned and another 25 scheduled for restoration, ABB’s collaboration with ACC illustrates how targeted modernisation, digital monitoring and circular maintenance practices can extend the operational life of critical equipment while supporting more efficient and sustainable cement production.
