Dimensional and mass characteristics of forwarders     pdf     HR     EN 387
Timber forwarding is characterised by carrying timber clear of the ground and loading timber assortments by a hydraulic crane, which results in the requirement for a parallel network of secondary forest infrastructure network where the distance between trails equals to double span of the hydraulic crane.
The paper presents 1) dimensional and mass characteristics of forwarders considering ISO 13860 (2016) standard and 2) forwarder load distribution plan developed by the German Kuratorium für Wadarbeit und Forsttechnik (KWF) to assist forestry experts in the purchase and use of these forest vehicles.
The heavy eight-wheel forwarder Komatsu 875 was selected as an example. Its dimensional and mass characteristics are shown based on measurements and the load distribution plan, aiming to evaluate the vehicle.
A critical comment is also given regarding the ISO 13860 (2016) standard due to the lack of some dimensional (length and height of the front and rear overhangs of forwarders, approach and departure angles and clearance radii) and mass (position of the centre of gravity point) of forwarders. These characteristics describe and serve to model its mobility during timber forwarding concerning the direction and longitudinal slope of the terrain. In addition, the ISO 13860 (2016) standard does not explicitly mention any indicator of environmental suitability (e.g. nominal ground pressure).

Key words: mobility and performance characteristics of forwarders; ISO 13860 (2016); load distribution
