“One of the reasons we went for the bulldozer is that we don't have to shift it as much. We have a wide spread - we don't have to go down the hill and come straight back up again because of the way the fairleads work. We can shoot down the hill and go anywhere we want to.”
- Alan Sinton of Sinton Logging, New Zealand
How did the remote operated bulldozer come about?
Lars Rosewarne, co-inventor of Rob, has been running his logging contracting business for over 25 years, cutting over 600,000 tonnes a year.
This is no mean feat in an area dominated by steep hillsides, and slippery clay soil.
Traditional logging machinery becomes unstable at 15 to 20° slopes. And this conventional equipment can only be used for 7 months of the year, as it is too wet and rainy to operate safely the rest of the year.
Then, because of safety issues in the logging industry, in 2013 New Zealand's largest forest owner decided that 100% of ground based harvesting and 80% of steep slope harvesting would need to be mechanised within a year.
Lars Rosewarne and forest machinery engineer Iain May realised they had the perfect solution: Rob, the Remote Operated Bulldozer. Rob is the intellectual property of Rosewarne & May Limited, New Zealand.
Rob is now for sale worldwide.
