FOREST HARVESTING MACHINERY INDUSTRY NEWS New tracks
Tyre chain manufacturer Pewag Austria GmbH chose to have the world premiere of its new tracks for forest machines at SkogsElmia. “This is the result of two years’ product development with the aim of creating more durable tracks,” said Hans Niklasson, who is in charge of Pewag’s Nordic sales.
The firm is a world-leading manufacturer of tyre chains for the mining industry, but it also makes chains for forest machines. Tracks had never been part of its range, but they are in increasing demand as more and more attention is focused on the issue of ground damage. The result is three types of tracks for different ground conditions with a larger tempered surface and three asymmetrically placed studs on each of the forged links. This design is claimed to be more durable and provide a better grip in the forest. More information from

Half-new forwarder
Swedish manufacturer Ponsse PLC came to SkogsElmia with a forwarder that it introduced as 50% new. This was the company’s smallest model, the ten-tonne Gazelle.
“It’s new ahead of the centre pivot,” explained Eero Lukkarinen, Managing Director of Ponsse AB.
Gazelle shares one of its innovations with another nine harvesters and forwarders. This is a newly developed series of engines that meet the strictest environmental standards in accordance with Stage IV/Tier 4f. With the aid of afterburning and the addition of diesel exhaust fluid, pollutants are radically reduced. The machines equipped with the new engines are all labelled the Ponsse 2015 series. “We’ve also extended the service intervals and shortened the time

needed for daily maintenance by bringing the service points forward,” said Eero. The interval for a major service with the new engine is 1,800 hours with an in-between service after 900 hours. The previous intervals were 600/1,200 hours, which was already longer than other makes.
The cab on the Gazelle is also a new design, which features an improved work environment and better operator comfort. However, the major cab innovation is on another forwarder, which was also presented at SkogsElmia. This is the mid-sized forwarder Buffalo, with a load capacity of up to 15 tonnes, which now has a cab with an active levelling system called ActiveFrame. There is an extra frame for the cab, which is tilted sideways with the help of two pistons. The system alters the cab’s angle of incline when, for example, the machine drives over a stump. The levelling function reacts quickly and is a clear improvement to the operator’s work environment.

First forwarder
Finland’s Sampo Rosenlew Oy specialises in harvesting – both in agriculture and forestry, but presented its first-ever forwarder at SkogsElmia.
“Our harvester customers have been asking for a forwarder for years,” stated Harri Uusi-Rauva, the company’s Marketing Manager. The forwarder shown at the fair was the FR28, a conventional forwarder in the ten-tonne category. Low weight has been prioritised to reduce ground damage (unloaded the machine weighs just 13 tonnes).
However, an important factor is that its builder is Sampo Rosenlew as Uusi-Rauva made the point that, “It is simpler and more efficient for contractors to have a forwarder and harvester from the same manufacturer”.
