There was a time when forwarders became smaller and smaller. Low ground pressure and flexibility was more important than productivity. But whether you like or not, money rules. The large forwarders came back and in Sweden, according to a previous article, large forwarders are the most common. Let us introduce you to yet another example – the Komatsu 895.
Komatsu 895 forwarder
Komatsu Forest has its roots in the Finnish machine manufacturer Valmet, and to some extent Volvo BM. Later it became Partek Forest, and finally, in 2005, it eventually became a part of Komatsu – Komatsu Forest.
Komatsu Forest believes in the future. They are building a brand new factory close to the headquarters in the north Swedish town Umeå. A remarkable project in many ways. It will be the most modern factory for CTL-machines (Cut-To-Length) in the World.
Sturdy machine
Of course I wanted to pay a visit to one of those giants. So, I went to one that is owned by the Swedish state forest Sveaskog and operated by Mikael Pettersson.
