The power of Kobelco’s XD series excavators has proven to be indispensable for a quarry operator working on the hard rocks of WA. When WA Kobelco dealer LiftRite reached out to road construction materials supplier WA Limestone to try out the new SK500XDLC, Director Steven Della Bona could be forgiven for feeling a little sceptical. After all, the family-owned company had been operating for more than 40 years, establishing itself as one of the biggest raw material providers in the state, with quarries strategically located all over the Perth metropolitan area. From these locations, WA Limestone supplies over 30 different types of products to contractors, government, and the wider WA public.
