At Hamilton by Design, we see ourselves as more than engineers — we are problem-solvers who bring both science and experience to the table. Every bulk material transfer is unique, and each one carries its own challenges. By combining the principles of particle physics with decades of hands-on site experience, we design chutes and transfer points that perform in the real world, not just on a computer screen.
We are a small, specialised company, not a large corporate machine. That means you deal directly with the people who understand your operation, your materials, and your challenges. We take pride in our ability to stand on-site, watch the flow of material, and recognise behaviours that only years of experience can teach. This gives us the clarity to engineer practical solutions that keep your plant running reliably.
For us, your success is our success. We measure our achievement not by the number of projects we complete, but by the value we add to your operation — less dust, less wear, fewer stoppages, more tonnes moved.
At Hamilton by Design, we believe that every bulk material transfer is an opportunity for improvement. What appears to be a simple flow of rock, coal, grain, or powder is, in reality, a particle physics problem waiting to be solved. By approaching these challenges with precision, creativity, and hands-on knowledge, we deliver chute designs that do more than move material — they protect assets, enhance performance, and improve the bottom line.
We are a small, specialised company with a wealth of on-site experience. Our engineers have spent years in the field, watching, listening, and learning how different materials behave under real conditions. This raw experience gives us a unique advantage: we can see and understand particle flow first-hand, not just through numbers on a screen. While many large organisations rely solely on computer models, we combine advanced simulation with practical insight, ensuring solutions that work not only in theory but also in practice.
Our team thrives on solving the complex problems others overlook:
Redirecting hard rock at speed without spillage or damage.
Handling sticky coal without blockages or hang-ups.
Containing fine powders without dust plumes or health risks.
Transferring fragile grains without breakage or product loss.
Extending chute, liner, and belt life with robust material-on-material flow designs.
We approach every challenge with the mindset that your success is our success. When your plant runs reliably, safely, and efficiently, we succeed alongside you. That’s why we design transfer points that:
Absorb and dissipate energy from high-impact lumps.
Control dust and minimise degradation for cleaner, safer operations.
Extend equipment life by reducing wear and maintenance.
Adapt to variability in feed size, flow, and moisture.
Boost throughput and availability by minimising stoppages.
In a world where margins are tight and environmental responsibility is critical, Hamilton by Design offers a personal, client-focused approach that puts performance and partnership at the centre. We are not a large organisation pushing generic solutions — we are a dedicated team that listens, observes, and engineers smarter outcomes, one particle physics problem at a time.
Designing for Developing Hazards: Lessons from the Derrimut Crane Collapse
Crane accidents are among the most visible reminders of the risks inherent in construction. The collapse of a crane at a data centre site in Derrimut, Melbourne, brought attention once again to the vulnerability of temporary lifting structures. While formal investigations are still underway, and no conclusions should be drawn prematurely, the event provides a valuable opportunity for reflection within the engineering community.
This article considers the collapse not as an isolated failure but as a case study in hazard identification. In particular, it highlights how mechanical engineers must adapt from a static, design-phase view of risk to a dynamic, real-time approach to hazard monitoring. Wind, soil stability, and load conditions are well-known hazards. But with modern tools — including LiDAR scanning for obstacle detection — engineers can move toward a future where developing hazards are continuously tracked, anticipated, and controlled.
From Hazard Identification to Live Hazard Monitoring
Hazard identification has traditionally been a design-phase process: engineers anticipate risks, apply safety factors, and create conservative margins. This remains essential. Yet the Derrimut collapse illustrates the limits of a static model in a dynamic environment.
Cranes are exposed to evolving hazards:
Wind gusts that change minute by minute.
Soil stability that shifts with rainfall, excavation, or groundwater.
Obstacles such as power lines or nearby structures, which can create cascading risks if struck.
Load dynamics, including swinging or sudden movement.
What is needed is a transition from hazard identification to hazard monitoring: a continuous loop where design assumptions are validated against real-time data, and where developing risks are detected before they become failures.
Wind Hazards: Predicting the Unpredictable
Wind is a leading cause of crane collapses. Engineers know the mathematics: pressure rises with the square of velocity. A 50 km/h gust exerts twice the force of a 35 km/h breeze.
Most cranes today are fitted with anemometers and alarms, but these are often basic: a single reading at a single point, with alarms sounding when preset thresholds are exceeded. This approach can miss:
Local gust variability along a long jib.
Interaction with crane orientation (wind hitting the broadside is more critical than aligned wind).
Forecasted conditions that could deteriorate within minutes.
Next-generation wind monitoring could include:
Multi-point sensor arrays on cranes.
Integration with Bureau of Meteorology gust forecasts.
AI models predicting when risk thresholds will be exceeded, not just reporting when they are crossed.
Automatic crane repositioning to minimise wind exposure.
This transforms alarms from reactive to predictive — the difference between warning after a hazard is present and anticipating before it materialises.
Soil Hazards: Stability Under Load
Ground conditions are another silent but critical hazard. Outriggers may impose hundreds of kilonewtons on pads, meaning even small soil weaknesses can lead to tilting or overturning.
Engineering practice already includes soil investigations: boreholes, CPT, SPT, and FEA models. But these tests capture conditions before installation, not necessarily during operation. Soil strength can change due to rainfall, groundwater shifts, or nearby excavation.
Live soil monitoring can be achieved with:
Load cells under mats to track ground reactions.
Settlement gauges to detect tilt.
Piezometers for pore pressure during rain events.
Integrated warnings when ground resistance trends downward.
This approach acknowledges soil as a living hazard that changes daily.
LiDAR and Obstacle Detection: Power Lines and Proximity Hazards
One striking feature of the Derrimut collapse was the crane’s boom striking power lines. Contact with utilities is a recurrent hazard in crane operations worldwide. While operators are trained to maintain exclusion zones, in practice visibility, fatigue, or unexpected boom movement can still lead to contact.
LiDAR scanning offers a solution.
How it works: LiDAR (Light Detection and Ranging) emits laser pulses to map surroundings in 3D with centimetre accuracy. Mounted on a crane, it can create a live digital map of nearby obstacles.
Application in cranes:
Detecting and mapping power lines, buildings, or scaffolding in the lift path.
Setting proximity alarms when a boom, hook, or load approaches a defined clearance.
Combining with wind data to predict if gusts could push the load into restricted zones.
In aviation, LiDAR and radar-based systems are standard for obstacle detection. In construction, adoption is patchy. Yet the technology exists, is cost-effective, and could dramatically reduce risks of contact with hazards like live power lines.
LiDAR’s strength lies not only in static mapping but in detecting movement — for example, when a suspended load begins to swing toward a power line due to a gust. This is a quintessential developing hazard, one that static design could never fully capture.
Integrated Hazard Dashboards
Wind, soil, and LiDAR obstacle detection all provide valuable data. But their true power lies in integration. Imagine a crane operator’s cabin equipped with a single dashboard displaying:
Wind speeds and gust forecasts, colour-coded for risk.
Soil reaction forces under each outrigger, with alerts if settlement is trending.
LiDAR mapping of nearby structures and power lines, with real-time clearance zones.
Predictive risk models showing probability of instability or contact over the next 30 minutes.
This integration mirrors aviation’s cockpit: multiple inputs fused into actionable guidance. For cranes, such systems could shift the operator’s role from reactive decision-maker to proactive risk manager.
AI as a Predictive Partner
Artificial Intelligence has a natural role in hazard monitoring:
Sensor fusion: combining wind, soil, and LiDAR inputs into coherent risk profiles.
Prediction: learning from past crane incidents to forecast when risks are likely to escalate.
Decision support: providing operators with clear options (“safe to continue lift for 20 minutes” / “halt operations — clearance margin < 1m”).
The challenge is balance. AI should not replace human oversight, but augment it. Over-reliance could create new vulnerabilities if operators become complacent. The design challenge is to build AI into systems that support human judgment rather than substitute for it.
Ethics and Engineering Responsibility
The Derrimut collapse underscores the ethical responsibility of mechanical engineers. Hazard identification is not just a design requirement; it is a matter of public safety. The profession has a duty to anticipate, detect, and control risks wherever possible.
The tools now exist to monitor developing hazards — wind sensors, soil gauges, LiDAR scanners, and AI dashboards. If lives and infrastructure can be protected through wider adoption of these tools, then the question becomes one of responsibility: should they be optional, or mandatory?
Open Questions for the Future
Would integrated live monitoring have reduced the risks at Derrimut?
Should all cranes be fitted with LiDAR obstacle detection as standard?
Do we already have enough technology, but lack regulation and enforcement?
What role should AI play in balancing predictive insight with operator autonomy?
Conclusion
The Derrimut incident remains under investigation. No conclusions can be drawn about its specific cause until findings are published. Yet as a case study, it illustrates the broader point that hazards in crane operations are dynamic. Wind, soil, obstacles, and loads evolve minute by minute.
Mechanical engineers have the tools — wind sensors, soil monitors, LiDAR scanners, integrated dashboards, and AI — to detect these developing hazards. The challenge is to move from a culture of static design assumptions to one of continuous hazard monitoring.
The ultimate professional question is this: If aviation can integrate multiple systems to monitor and predict hazards, why can’t construction do the same for cranes? And if we can, how soon will we accept the ethical responsibility to make it standard?

In the mining industry, system uptime isn’t just a goal—it’s a necessity. Transfer points such as chutes, hoppers, and conveyors are often the most failure-prone components in processing plants, especially in high-wear environments like HPGR (High Pressure Grinding Rolls) circuits. Abrasive ores, heavy impact, fines accumulation, and moisture can all combine to reduce flow efficiency, damage components, and drive up maintenance costs.
At Hamilton By Design, we help mining clients minimise downtime and extend the life of their material handling systems by applying advanced 3D scanning, DEM simulation, smart material selection, and modular design strategies. This ensures that transfer points operate at peak efficiency—day in, day out.
Here’s how we do it:
Optimised Flow with DEM-Based Chute & Hopper Design
Flow blockages and misaligned velocities are among the biggest contributors to transfer point failure in the mining industry. That’s why we use Discrete Element Method (DEM) simulations to model bulk material flow through chutes, hoppers, and transfer transitions.
Through DEM, we can simulate how different ores—ranging from dry coarse rock to sticky fines—move, compact, and impact structures. This allows us to tailor chute geometry, outlet angles, and flow paths in advance, helping:
Prevent material buildup or arching inside hoppers and chutes
Align material velocity with the conveyor belt speed using hood & spoon or trumpet-shaped designs
Reduce wear by managing trajectory and impact points
Not all wear is the same—and neither are the materials we use to combat it. By studying the abrasion and impact zones in your chute and hopper systems, we strategically apply wear liners suited to each application.
Our engineering team selects from:
AR (Abrasion-Resistant) steels for high-wear areas
Ceramic liners in fines-rich or ultra-abrasive streams
Rubber liners to absorb shock and reduce noise
This approach reduces liner replacement frequency, improves operational safety, and lowers the risk of unplanned shutdowns at key transfer points.
Dust and Spillage Control: Cleaner, Safer Operation
Dust and spillage around conveyors and transfer chutes can lead to extensive cleanup time, increased maintenance, and health hazards. At Hamilton By Design, we treat this as a core design challenge.
We design chutes and hoppers with:
Tight flange seals at interface points
Enclosed transitions that contain dust at the source
Controlled discharge points to reduce turbulent material drops
This reduces environmental risk and contributes to more consistent plant performance—especially in confined or enclosed processing facilities in the mining industry.
Modular & Accessible Designs for Faster Maintenance
When liners or components need replacement, every minute counts. That’s why our chute and hopper systems are built with modular sections—each engineered for fast removal and reinstallation.
Key maintenance-driven design features include:
Bolt-on panels or slide-in liner segments
Accessible inspection doors for safe visual checks
Lightweight modular components for easy handling
These details reduce labour time, enhance safety, and keep your plant online longer—especially critical in HPGR zones where throughput is non-stop.
Precision 3D Scanning & 3D Modelling for Retrofit Accuracy
One of the most powerful tools we use is 3D scanning. In retrofit or brownfield projects, physical measurements can be inaccurate or outdated. We solve this by conducting detailed laser scans that generate accurate point cloud data—a precise digital twin of your plant environment.
That data is then transformed into clean 3D CAD models, which we use to:
Design retrofits that precisely match existing structure
Identify interferences or fit-up clashes before fabrication
Reduce install time by ensuring right-first-time fits
This scan-to-CAD workflow dramatically reduces rework and error margins during installation, saving time and cost during shutdown windows.
Real-World Application: HPGR & Minerals Transfer Systems
In HPGR-based circuits, transfer points between crushers, screens, and conveyors experience high rates of wear, dust generation, and blockages—particularly where moisture-rich fines are present.
Here’s how Hamilton By Design’s methodology addresses these pain points:
DEM-based flow modelling ensures the HPGR discharge flows cleanly into chutes and onto conveyors without buildup.
Hood/spoon geometries help track material to belt velocity—minimising belt wear and reducing misalignment.
Strategic liner selection extends life in critical wear zones under extreme abrasion.
Modular chute designs allow for fast liner swap-outs without major disassembly.
3D scanning & CAD design ensures new chute sections fit seamlessly into existing HPGR and conveyor frameworks.
By designing smarter transfer systems with these technologies, we enable operators to reduce downtime, increase liner life, and protect critical assets in high-throughput mining applications.
Faster maintenance turnarounds during scheduled shutdowns
3D scanning & CAD integration
Precise fit, reduced installation time, fewer errors during retrofit
