Dyna engineers solutions for common bulk problems

Local expertise, design and manufacturing are Dyna Engineering’s tools to solving the challenges facing Australian conveyors.

Local expertise, design and manufacturing are Dyna Engineering’s tools to solving the challenges facing Australian conveyors.

When Thomas Greaves, General Manager of Dyna Engineering, began doodling on a piece of paper one afternoon, he did not expect it to amount to anything revolutionary.

However, when his father Graeme (the founder of the company) walked past, the two of them had a lightbulb moment.

One of the designs that Thomas had drawn was an X pattern for a conveyor guard. One thing led to another, and suddenly what started off as an idle drawing became what Thomas calls a game changer for the conveyor industry.

This design, exclusive to Dyna Engineering, offers significantly greater strength and allowed the company to manufacture the conveyor guard out of recyclable/recycled high-density polyethylene (HDPE).

“Conveyor guards in general are used to protect personnel from harm associated with conveyors, either by preventing them from entering the danger zones or to contain rogue material within the conveyor,” Thomas says.

“The ‘X’ design in our mesh gives more strength and better deflection properties than other HDPE guards on the market. Our patented ‘X’ shape design increases the guard’s strength substantially (up to 60 per cent) in comparison to standard square mesh panels.

“So, as well as delivering reduced deflection, it is well above the minimum Australian standard, which will help keep personnel safe,” he added.

Dyna Engineering is a family-owned company that operates out of its head office in Perth, Western Australia. It specialises in the design and manufacture of conveyor equipment and related services that can be tailored to an extensive range of applications, operations and conditions.

The company keeps its finger on the pulse when it comes to the problems that face conveyors in Australia and aims to create products that make life easier for all involved. An example of this can be seen in its Dyna FastFit Scraper.

“If you’ve ever had to remove a primary or secondary conveyor scraper for maintenance or blade replacement, you’ll know how awkward, difficult and dangerous it can be,” Thomas says.

“That’s why we wanted to design a better solution that allows quick and easy removal of the scraper assembly from the chute.”

By redesigning the primary and secondary scraper assembly, maintenance work on scrapers can be conducted safer and easier, outside the chute.

“It makes the job of the plant fitter a breeze by allowing fast removal of the scraper from the chute,” Thomas says. “There is no need to get inside the chute, eliminating the need for scaffolding and confined space permits.”

All of the work can be completed from outside the chute, simply by removing two bolts so the scraper shaft and blades can be removed in one motion. This means all of the maintenance can be done in a location where fitters can work in an ergonomically correct working position. Safety is also improved by allowing the scraper assembly to be removed from the often high and awkward confines of the chute.

Dyna’s FastFit Scraper solution has been designed to be simple enough that even a novice can quickly learn. It allows for the removal of the scraper shaft and blades without losing any of the settings as the system is self-aligning, self-lubricating and self-locating. A short demonstration video can also be found on the company’s website.

Stainless steel is used for the construction to avoid corroding, rusting or paint damage and they are available in primary and secondary versions with polyurethane and carbide blades for belt widths from 350 millimetres to 3500 millimetres wide.

Dyna Engineering is proud of being fully Australian owned and operated, and as its manufacturing is largely done locally, components can be made in as little as a couple of days. This has a lot of appeal when compared to the usual weeks or months which can apply to others sourced from overseas.

“A major reason for this has been our focus on providing consistent quality and honouring our delivery promises,” says Dyna’s Sales Engineer Reddy Emmadi.

“Over the years, we have built a strong and loyal band of clients. We have absolutely no intention of letting them down through unacceptably long lead times for
off-shore manufacturing.”
