HyRail Trucks – Rail Maintenance Vehicles

Built for FMG Mining, this Isuzu truck is fitted with a HyRail system which means it has Train Wheels and drive system on the front and rear and therefore can travel on the client's rail line.  The truck can operate on regular roads using its rubber wheels.  When it gets to a rail line, it straddles the rail line, and the HyRail units fold down lifting the truck off its rubber wheels.

The role of this vehicle is to carry equipment along the rail line and perform track maintenance.

Now the question is why did they go to all the trouble of coating the entire underbody, chassis, diffs, HyRail unit,  diesel and air tanks?

Well, the answer is simple – Most of the roads this truck travels on to, and from, the rail line is mainly gravel which is sprayed with water 24hrs a day for dust suppression.  It is a waste to use good clean drinking water, so they often use second grade reclaimed water from dams or the ocean, and it is very salty.

Salt Water + Dirt + Chipped Paint = RUST !

… and very quickly it will rust – this truck is worth about $500,000 so they would like it to last up to 10 years.

So from both a cost saving and ease of application perspective we use a combination of High Build Industrial Epoxy and Rhino Linings polyurethane coating system.

First, everything is sprayed with a 300µm DFT coating of our High Build black Epoxy (known as Beamastic). This product also provides an excellent primer or base for the Rhino product.

Then we merely spray Rhino Duraspray on anything we think will cop the flying debris.  This is typically the chassis rails near the rear wheels, the fuel and auxiliary tanks that stick out the side, both diffs, and in this case, the HyRail units mainly because they are costly and the client wanted the added insurance of the double coating (Epoxy and Rhino)

Providing Maximum Wear Resistance and Operational Life of Chute Slides

Wear Coat and Final Coat Protection for JetCrete Chute Slides

This particular project was for Jetcrete, Australia’s largest specialised shotcrete contractor for the mining and construction industry. The company was looking for a long-term durable solution that prevented both wear and concrete hang up.

Concrete chute slides are used to effectively control the flow of concrete from cement truck bowls to the location where the concrete is to be deposited.  However, due to the sliding abrasiveness of wet concrete, hang up is always an issue and can often contribute to onsite project delays.

To complete the project each chute was primed with RhinoPrime 251 in preparation for the application of RhinoChem 2170 a spray applied, seamless chemical and abrasion resistant polyurethane protective coating.

 

 

As wear was an issue with the chute slides a tinted wear coat was required, RhinoChem was applied in two different colours.  The first coating (coloured pink), was applied at a thickness of 3mm, its primary purpose is to serve as a wear indicator.  A final 3mm (cream tinted) coating was used to produce a low coefficient of friction reducing hang up, sticking or carryback of the concrete.

RhinoChem 2170 is a monolithic, seamless lining which conforms to any shape or size, it is especially suitable for applications that require a fast turnaround and an extended life cycle.

Chute Wear Liners

Large in size and weight, these 2-tonne wear plates line a massive iron ore chute at the Yandi BHP mine site in the Pilbara, WA.

Australian Resin Coatings was engaged by Enduraclad International to provide a protective coating for the tungsten wear plates to protect the edges from chipping on installation - this proved successful

 

 

An ongoing trial, which is forecast to be carried out over the next five years, is to ascertain the suitability and durability of RhinoChem 2170 polyurethane and its ability to lengthen the life of the liners and help stop the ore from chipping the wear liners out from the edges.

Application Process

The surface area of the wear plates was prepared and primed with RhinoPrime 251.  Depending on the depth of the wear plate edge, 3-8mm of RhinoChem 2170 was applied to provide an extremely durable, abrasion and impact resistant surface.
