Large mining trucks are the cornerstone of the mining industry, moving material such as coal, sand, rock and ore. They are built tough for the terrain they work in, but sometimes some added protection is required due to the highly corrosive environment that exists on a mine site. Following are three case studies of work completed by Rhino Linings of Singleton, NSW Australia.
The cab of Komatsu Haulcab
This Komatsu 830e 240 ton Haulcab cab is part of a Rio Tinto fleet used in the highly corrosive environment that exists on a mine site. The cab had started to corrode, and there was concerned the existing floor matting did not meet their slip-resistant requirements. Additionally, dirt and moisture were being trapped beneath the partially bolted down mat causing further corrosion. Moisture was also creating an odour in the cab.
The cab was first sandblasted and repaired before application of Rhino Prime 251 and Rhino TUFF STUFF. Slip-resistant particles were also applied to finish off the application. The company was pleased with the cab and intends, over the coming months, to have the same work carried out on the balance of their fleet of Komatsu dump trucks.
This Caterpillar 793 Haul Truck is part of a fleet used in the extremely corrosive environment that exists on mine sites.
The 5,000 ltr fuel tanks of these Caterpillar 793 Haul trucks, located directly behind the front wheel, acts as a mudguard and are incredibly vulnerable to impact and of course corrosion. To obtain a much longer service life, the client required the fuel tanks to have as much impact and corrosion resistance as possible.
Due to the weight of these tanks, the work included having the tank suspended by a crane to prepare the area before the application of Rhino TUFF STUFF ®. The entire tank was painted Caterpillar yellow upon completion.
The fast cure time of Rhino TUFF STUFF® allows for easy application to vertical and overhead surfaces. The client intends to have further fuel tanks sprayed as they are removed for inspection.
Rhino Linings protective coatings are used in many areas of a mine site including bunds, machinery, flooring, conveyor belt maintenance in addition to heavy vehicle protection for corrosion and impact.
The mudguard of a Caterpillar 798 Haul Truck is situated directly over the front left-hand wheel and is extremely vulnerable to impact and corrosion. Rhino Linings TUFF STUFFwas used in this area for its corrosion and impact protection properties. Also, the battery box and door were also sprayed to prevent the battery from shorting out on the metal surface should it become dislodged from its mounting.
The first guard has been in operation for well over 18 months now and is showing no signs of wear.
A further three guards have been sprayed since the trial.
Rhino Linings spray applied products continue to provide the same protection for large vehicles such as these and other industrial mining applications on mine sites throughout Australia and Internationally.
