Hydrostatic mechanical transmission
This innovation to forwarders has already proven it’s ergonomic and very fuel efficient operating characteristics in agricultural tractors. The setup of the transmission controller and the vehicle controller needs to be very different due to the request to drive safe and fast downhill with a load. Still an improvement like with the agricultural tractors can be expected, that is a 30% lower fuel consumption during driving. The impact of this module on the working process is that longer hauling distances can be economically forwarded and the need for more forest roads is reduced. Moreover, as the forwarder can drive longer distance, there is less need to interrupt the process for refueling. This supports sustainable wood production without burdening the forest with more forest roads.
Hybrid hydraulic crane system
This innovation of cranes, including forwarder cranes, should reduce the fuel consumption during loading and unloading processes by 30% over a conventional load-sensing system and increase the speed for loading and unloading, if the operator can control the higher speed.
Especially the high number of movements in narrow thinning will show the biggest improvement. This helps selective thinning being more competitive than clear-cutting and supports sustainable wood production from forest managed on a multifunctional basis, as a source of recreation and as a permanent production forest. Of course, energy saving improves the process of loading and unloading and makes it more economical and more environmental friendly.
