New technological solutions for waterlogged forests by cable yarding

Perspectives on Central European Cable Yarding Systems

Cable Yarding Technology has a long tradition in the Central European Alps. Outside Europe, sledge yarder technology became well known during the 1960's while the first European tower yarders were introduced during the 1970s. Although there has been much effort to improve yarding technology, only little is known about it outside Europe. The paper aims to present the state-of-the-art of both, ya...

Efficiency of Topping Trees in Cable Yarding Operations

The extraction of biomass and nutrients out of the forest is implicit to every harvest operation. In cable yarding, whole-tree harvesting (WTH) has become more prevalent in the last few decades and processing takes place at the roadside. There is a concern that WTH impairs site productivity due to nutrient removal. One option to increase the amount of biomass remaining in the stand is to top th...

Efficiency and Ergonomic Benefits of Using Radio Controlled Chokers in Cable Yarding

Nacrtak Chokers are wire rope slings used to secure the felled trees to the rigging during cable yarder extracting. Standard chokers are set manually by the choker-setters along the corridor, and then unhooked manually by the yarder operator at the landing. Radio-controlled chokers are also set manually but have the advantage that they can be released remotely at the landing. In addition to pos...

Analysis of Accidents During Cable Yarding Operations in Austria 1998–2008

Nacrtak This paper deals with accidents in the period 1998 – 2008 reported during harvesting operations in ÖBf AG, Austria’s largest forest enterprise, with a focus on cable yarding. In total 1888 accidents were recorded with 8.7% of these associated with cable yarding activities. The overall accident rate amounted to 36 incidents per million cubic meter extracted by cable yarder. There was a c...
