Filling the void
MINING is a tough game.
It all comes down to how much material you can extract for the least amount of money and any interruptions to that extraction process cost companies many, many thousands of dollars.
Specialising in on-site earthmover and OTR machinery tyres, OTR Tyres’ expert team of mobile tyre technicians manage a fleet of field service units and tyre fitting trucks for all on-site fitting and maintenance.
OTR staff are experts in the mobilisation and de-mobilisation of heavy equipment, working to minimise downtime for tyre removal and re-fitting once on site.
With global sourcing and supply capacity, OTR Tyres has the ability to source the right tyres and wheels for your requirements and is the chosen project partner for major state, national and international projects.
OTR Tyres has factory direct access to all product categories and the capacity to ensure continuity of supply of competitively priced tyres of all segments, from budget to premium brands.
It can also arrange tyre disposal and offer trade-in services.
OTR Tyres’ extensive range of new and used (quality part-worn) OTR tyres offers a real commercial advantage, particularly if preparing machinery for sale, or if to match with existing tyres in service.
OTR Tyres combines world class facilities, tools and equipment with professional and experienced technicians to ensure tyres are serviced to the highest standards.
The team of tyre fitters and service technicians are highly trained and assessed regularly to ensure compliance to industry best practice.
The company offers a comprehensive range of tyre service and repair options including on-site coverage, call-outs and emergency repairs.
With a fast and reliable turnaround for all inspection and repairs, your equipment will be back on the road as soon as possible.
Get rid of flats for good
Have your operations ever been disrupted due to tyre failure?
One method that is proven to extend tyre life, eliminate punctures and virtually eradicate unexpected tyre repairs, is the use of solid filling.
The process involves filling the void in the tyre with a compound other than air to make it impervious to punctures or ruptures. Technology advances and one of the most highly adopted solid fill products in the world, Carpenter’s world-leading Rely T-25 compound, has proven itself time and again to reduce solid-shock and give drivers the same ride as pneumatic tyres.
Rely T-25 is available from TyreFill WA, part of OTR Tyres, based in Bellevue, WA.
It has been solid filling tyres for use in mining, agriculture, civil construction and aerial platforms for many years.
That experience has enabled the company to develop techniques to not only completely fill tyres and eliminate air pockets but also to set the ‘tyre pressure’ to OEM specs and, being a solid compound, that pressure does not vary for the life of the tyre.
A special storage and mixing facility is required to fill tyres with Rely T-25 as each of the two parts of the polymer compound must be stored at a specific temperature.
Dual pumps are used to draw Part A and Part B from their individual containers and push them through a mixing screw before the combined liquid compound is forced through the valve of the tyre, which is mounted to the rim.
As the tyre fill compound enters the tyre, displaced air exits from a vent hole – just like bleeding a brake cylinder.
Once the tyre is filled with exactly the right volume of T-25 to give the required working pressure, it is allowed to set for 48 hours. From that point the tyre is flat-proofed and will be serviceable, without fail, until the tread is worn down to the witness marks.
Benefits of solid filling
The benefits of solid filling tyres are manifold as they become impervious to nails, spikes, slag and rocks.
