ABOUT ROCK MACHINERY.....

Best Seller – 22-ton Venom Log Splitter
Since its release in 2011, the 22 ton Venom has become the exemplar of what a log splitter should be. It is now established as one of the best splitters available in the UK and Europe.
Rock Machinery has taken customer feedback onboard and improved the splitter year on year – adding a working table, road towing axle, and making overall design improvements. Today, the 22 ton Venom looks quite different to how it did in 2011 but it still retains its robust workhorse features that make it a hit with professionals and domestic users alike. With features that include a Briggs and Stratton Vanguard engine, vertical and horizontal splitting positions, and ergonomic controls, this machine really has no equal.
