Mining and geological characteristics of the majority of the world’s deposits for the past few years significantly deteriorated , and mining companies have to constantly increase the volume of processed rocks to save volumes of production at least at the same level .
The main means of moving rocks on most quarries are powerful trucks of the ultraclass , Which is constantly being improved , acquiring all new and new opportunities .
This ” caterpillar ” called Rexx , and makes it a little-known in our Australian company Bis . In fact, these guys specialize in providing mining services, logistics and even processing materials . But here is something they clicked , and not so long ago engineers Bis built at its plant in Western Australia, an innovative off-road truck Rexx . As you can see in the pictures, the train really has 20 standard tires instead of the usual four extra – large tires , typical of other mining trucks .
According to the manufacturer , thanks to this, loaded up to 160 tons, the Rexx is able to travel at a speed of 60 km / h 4 times further (35-40 km) than conventional dump trucks . Why ? Yes, because that familiar to us dumpers limited in this most ” long range ” – they simply overheated and out of the system bus . And for standard tires that Rexx uses , heating is completely uncritical . In addition, in case of breaking one wheel or even several , you can safely continue to move .
Unique multi-axis design also provides a more uniform distribution of the load on the 5-axis and 20 buses – it allows you to dump truck to work in the most stringent conditions of operation . Surprisingly , but the diameter of the reversal of the unusual truck is just 13.6 meters, so it is reasonable to talk about its maneuverability in confined working spaces. If this in the company Bis say , that Rexx differs twice less , than at the usual truck, consumption of fuel , and this , they say , reduces the emissions of greenhouse gases, which for many markets of the planet is an important component when marketing products.
According to representatives of the company , this product will be part of a set of individual decisions Bis for loading and transporting , which also includes in itself double road trains , providing a highly competitive integrated solution for the mining operations. Speaking at the presentation of the product in Perth, general director of Bis Brad Rogers said , that Rexx has changed the rules of the game in the mines, including in itself the best features of long-haul trucks and mining dump near the action .
“The robust and simple design of Rexx draws on our existing knowledge and resources . This means , that we were able to maintain our operating costs at a low level , that allowed Bis save money customers with the help of our model of services “, – said he. Rexx was developed to work on a narrow road with a low performance. According to Bies, the design provides a smoother ride and better visibility for operators , and also significantly improves tire management . The dump truck has also been designed for ease of maintenance .
Designed with a view of the very high requirements of security , Rexx is equipped with a system of control fatigue Bis , as well as cameras with 360 ° view cameras and rear viewing for more effective management of risk . Problem -duty dump trucks worth so as acute , ka to and 50 years ago. There are two solutions- either to make ever more powerful dump trucks ( like the legendary BelAZ-75710), or to build modular trains . The most unusual concept of such a plan is offered by the Slovenian company ITIEF .
Immediately note , that at the given instant of there is only one prototype instance ITIEF – company is young , and its concept of Ia while that – only in Security Systems ‘s sketches. But , and dey clearly realizable , plus at IIT FE big plans and big already th gamma -making , so that , perhaps , after a couple of years they will come to ry knock and take it the leading position . The main module is a 20-wheel truck ITIEF Truck with 5 leading (!) Axles. And not just leading , but also driven by . Modularity is in fact that of vr emya, does not exceed the present 15 minutes , with the truck can be dismantled block cockpit , turning it into Prica en, or shortened base ” unfastened ” multiple block axles. In other words , the entire truck is a constructor.
It is understood , that from the standard set of block axles, a block body , the block of cabins , can gather how least 6 different modifications : two axes with Capacity yu 180 tons, three axes at 284 m, four axis 380 m, five axes on 484 tons, six axles for 570 tons and 8 axles for 774 tons ! And the last two configuration will record among mining trucks , leaving behind even the ” BelAZ “.
Wheels , and Shih us for freight Ikov non-standard and so well designed ITIEF . They are designed to sverhnagru dressings, which are not mo gut withstand typical wheels for Kare -polar trucks . With one second hand , ” mnogokolosnost ” allows intelligently distribute load .
In so only at first glance on the trailer , especially from shestnadtsatiosnyh models, there is a natural question , how all this economy will be unloaded ?
