Rottne Industri AB, the forestry machinery manufacturer, is starting 2022 by launching two new cranes, the RK75 and RK310. The cranes will be mounted on Rottne H8D and Rottne H21D respectively.

“Our development work has been focused on simplifying service, improving operator comfort and increasing power,” Filip Wirbladh, machine engineer at Rottne Industri, says.

The Rottne H8D is a compact and flexible machine for stand-operating thinning. The Rottne H21D is a heavy-duty option for final cutting. Nevertheless, they both have one thing in common: strong and robust cranes for the purpose – which are now even better.

“The fact that we choose to manufacture our own cranes and harvester heads for our machines is really very satisfying, and it makes us unique,” Tobias Johansson, CEO Rottne Industri, says.

The RK50 has been around since the start of the century. It will now be replaced by a new crane with many improvements and innovations.

“We have been working on developing the RK75 for many years. In short, we have kept all the advantages on the older crane and added even more. The difference between the new and the old crane is very large,” Wirbladh says. “Generally speaking, everything is new, with the focus on the operator and service. With the RK75, we have developed a dynamic and durable product, where the operator will really notice a big difference.”

The list of improvements on the new crane is long. Everything from hardware to software has been looked over in detail, in order to develop a crane that will make both the work and the service easier.

“The guiding principles have been function, service and comfort. The crane is easy to do service on, while the operator gains softer and more precise operation thanks to reduced vibrations in the operating stages,” Wirbladh says. “In the long-term, operating a Rottne is also a financial win. Easier and simpler service and improved work in the forest saves time and thus, money.”

The crane on the Rottne H21D has also been fundamentally updated. The RK250 is replaced by the RK310, which has been tested and developed over many years. The advantages include that a new crane is gearless, direct driven, and has a slewing motor with greater efficiency, as well as has a stronger bearing between the first boom section and outer jib.

“Over the years, we have identified points for improvement. With the RK310, we have taken the best from the earlier crane and developed something even better,” Wirbladh says.

Both of the cranes have been test run for a long time with excellent results.

“There are many years of development behind this. That we can now mount them on our own machines and exhibit them to the market really feels very satisfying,” Johansson says, who sees a bright future for the Swedish company. “We have taken the right decision in our work with long-term goals and the market is certainly on our side. This is made clear by the great demand for our machines, both harvesters and forwarders.”
