Merry Christmas & a Happy New Year!
Closed Christmas Day, Boxing Day & New Year Day
Not every safety risk announces itself. Some of the most persistent hazards in heavy engineering workshops are the ones that have been quietly accepted as routine, the tasks everyone has learned to work around without ever questioning whether there’s a better way.
The steady rest removal on our Mazak Integrex i400 was one of those tasks.
The Mazak Integrex i400 is a high-performance milling centre designed for precision single-operator use, however, removing and reinstalling the steady rest had never matched that standard.
The process required two operators, a crane, a heavy lift at an awkward angle, and careful management of swing risk in a confined space. It was time-consuming, it pulled a second tradesperson away from productive work, and it introduced unnecessary risk to both people and equipment every single time it was done.
The machine was built for one person. There was no good reason the maintenance process needed two.
Rather than accepting it as an unavoidable quirk of the equipment, our drafting team asked a straightforward question: what if we just engineered the lift properly?
Before getting into the solution, it’s worth explaining the thinking behind it.
In engineering and workplace safety, risk is managed through a hierarchy of controls. At the top of that hierarchy, and the most effective intervention, is elimination: removing the hazard entirely. Below that sit substitution, isolation, engineering controls, administrative controls, and personal protective equipment (PPE) at the base.
The reason this hierarchy matters is that controls lower down the triangle require ongoing human behaviour to work. PPE only protects if it’s worn correctly, and is the last line of defence. Administrative controls only work if procedures are followed every time.
Engineering solutions, by contrast, build the protection into the process itself.
That’s what we were after here. Not a better procedure for managing a difficult lift, but a redesign that made the difficult lift less hazardous.
The temptation with a project like this is to measure by eye, make an educated guess at the balance point, fabricate something and see how it goes. That approach typically means multiple prototypes, repeated trial-and-error, and no guarantee the final result is actually correct.
Our drafting team took a different approach.
First, they conducted a full 3D scan of the steady rest in situ, generating an accurate digital model of the component exactly as it sits in the machine. From that model, they used CAD software to calculate the centre of gravity (COG) with precision. The custom lift plate was then designed to reposition the pick-up point directly over the COG, meaning the load would hang level, stable and controlled from the moment it left the machine.
No guesswork. No prototypes. No multiple attempts to get the balance right.
The solution was right the first time because the engineering work was done properly before anything was fabricated.
With the custom lift plate in place, the steady rest now lifts level and stable, with swing risk effectively eliminated. The load doesn’t tip or shift. It doesn’t require a second person to manage. It doesn’t require crane choreography in a confined space.
It’s a controlled, one-person operation.
That changes more than just the immediate task. It means one fewer person exposed to the risk of a heavy lift. It means the second tradesperson stays on their own work. It means the process is the same every time, regardless of who’s doing it, because the engineering has removed the variables.
This is what sits at the top of the hierarchy of controls: not a rule about how to be careful, but a physical change that makes the hazardous version of the task no longer possible.
This wasn’t a major repair job or a complex on-site breakdown. It was a targeted piece of engineering applied to a routine task that nobody had stopped to question.
That’s exactly the point.
At Morgan Engineering, the same thinking that goes into a complex fabrication or a critical machining job applies to the way equipment is handled day to day. If there’s an unnecessary risk in a process, we’d rather find it before it becomes an incident than after.
Our values are straightforward: fast, reliable and safe. In practice, that means proactively looking for the smarter approach, using digital precision rather than rough estimates, and designing solutions where safety is built in rather than bolted on.
Whether the job is a lifting modification, a machining challenge, a fabrication redesign or a complex on-site repair, the approach is the same: understand the problem properly, use the right tools to solve it accurately, collaborate with your teams to achieve the best outcome and build the result to last.
If there’s a safer way to operate something, we’ll find it and engineer it in. That’s not a value statement. It’s just how the work gets done.
