Rottne H8E-New Thinning Harvester

Rottne Industri AB launches Rottne H8E – a significant upgrade of the popular predecessor Rottne H8D.
The versatile harvester has been updated on several points and will be equipped with the new and stronger crane, RK75, and have optional boom control.
The first machine from the upgraded series of the Rottne H8E has just left the production facilities at Rottne. More machines are in the production line now.
– On the outside, Rottne H8E looks almost like Rottne H8D, but on the inside there are a lot of improvements and a lot of new and advanced technology, says Mathias Paulsson, Engineer of the Control Systems at Rottne Industri AB.
– The crane, with all its mechanical upgrades, makes the big difference and it was when we developed it, we have seen the opportunity to upgrade the entire machine.
RK50 has been around since the beginning of the 2000s. Now it will be replaced by RK75 with a lot of improvements and innovations. In short, all the benefits of the older
crane have been retained and more advantages have been added. Everything from hardware to software has been reviewed in detail in order to produce a crane that will make both the work and the service easier.
– The new crane has a completely new turntable that makes it more efficient with better durability and reliability. Compared to its predecessor, the crane has been
improved in all respects, which makes it stronger and with higher lifting power, says Mathias Paulsson.
– Among other things, it has a built-in position sensor in all cylinders that the control system recognizes. The boom control is moved at the driver’s command (out, in, up and down) and the system runs the extension automatically.
With the launch of the Rottne H8E, Rottne Industri is now taking another step forward in the development of flexible forest machines for efficient thinning work.
– We can proudly launch our first machine with a boom control developed here at Rottne. This, together with other improvements, strengthens our leading position in sustainable thinning for professional forestry, says Tobias Johansson, CEO of Rottne
Industri AB.
Demand for boom control for more of Rottne’s machine models is high and the company’s developers are constantly working on this. For the newly launched Rottne
H8E, it will be available from April.
