The JONSERED 2850S is an evolutionary development of the legendary Big Jon model, JONSERED 2490S. Its main components have been fully revamped and its boom geometry further developed, resulting in a significantly higher lifting capacity without compromising its light weight. Heavy tree-length logs require heavy-duty cranes. Excellent ergonomics, accurate controls and durable design combined with the speed of the hydraulics make the crane controls precise and easy to operate.
