Compendium of cable yarding production equations

Abstract

This paper is a compilation of most of the recent cable yarding production equations generated by the Forest Engineering Department at Oregon State University. Additional production equations found in the literature review have also been included. Background information for each of the studies involved has been summarized. Data is basically organized into a set of tables for small, medium, and large sized yarders. Each sheet in a set of tables contains a particular type of information, such as production data, equipment information, crew information, and physical characteristics of the sale area. Guidelines on the potential use of the compendium and a discussion of equations as predictive tools is provided. A graphical summary was developed to assist the reader in locating an equation representing a particular set of conditions.
