Caterpillar has released its new R2900 underground loader, which offers expanded emission control options in response to global regulations surrounding diesel engines.
The product allows mining companies who are facing stricter regulations, particularly in Europe and North America, to choose between emission configurations.
The R2900 will continue to deliver the 17.2 tonne payload that its predecessor offered, with the new load haul dump (LHD) allowing for extended durability and enhanced safety and productivity.
Caterpillar has particularly focused on the environmental impact of the new R2900 through using the fuel-efficient Cat C15 engine.
Using the Cat clean emissions module, the loader aims to limit particulate matter and nitrogen oxides (NOx) to almost zero while also meeting the EU stage V and Canada’s CANMET standards.
It also uses Caterpillar’s ventilation reduction system, which uses flow through or wall flow diesel particulate filters for improved underground air quality.
The R2900 also focuses on reduced maintenance time through its radiator, which incorporates a modular design with individual tubes that can be serviced independently.
Remote axle and transmission coolers and filters coupled with a single fuel tank which replaces the duel tanks in the previous model, facilitate easier access to the underground loaders, as the new tank can now be refuelled at ground level.
The machine health is monitored through the Cat Product Link Elite system that is capable of sharing data cross multiple destinations.
Critical information is now presented on a display in the Cat line-of-sight console while the R2900 also uses MineStar Command technology to enable teleremote and semi-autonomous operation from a distant operator station.
The R2900 can work with a range of bucket sizes to match material characteristics and optimise the machine’s productivity through introducing the Bolt-On Half Arrow ground engaging tools (GET) for bucket edges.
As opposed to the weld-on GET, the bolt-on GET offers more wear material and its design enables fast and simpler removal and replacement, while also easing pile penetration and promoting fast bucket loading.
