Creator:: Kimbell, Abigail R.
Abstract:: Tension relationships were determined in steel cable passed through a stump notch and anchored to another object. Tensions were measured in the cable coming into and leaving the notch with one full wrap on the stump. Data was collected from two sites with two test stumps (15.7 to 37.5 inches...
Resource Type:: Capstone Project

Creator:: Lucas, Alan R.
Abstract:: This project was one of several studies conducted during the summer of 1981 that were part of the Smallwood Harvesting Research Program administered through the Department of Forest Engineering, Oregon State University. The study looked·at the feasibility of falling and yarding whole trees as a combined activity in a cable...
Resource Type:: Capstone Project

Creator:: Lysne, David Holtan
Abstract:: Some results of a study conducted in the Sierra Nevada Mountains west of Lake Tahoe are reported. The study measured soil impacts resulting from the use of a Caterpillar Tractor model D6D, a John Deere wheeled skidder model JD-640, and an FMC Corporation model FMC 21OCA logging vehicle. The three...

Creator:: Stirler, Dennis John
Abstract:: There is much interest in the State of Vermont in cable harvesting. Since there are no time studies available for cable harvesting with various machines in Vermont, it is necessary to arrive at production and cost levels by a different method. The method chosen for this paper is made up...
Resource Type:: Capstone Project

Creator:: Campbell, Thomas M.
Abstract:: Time studies of logging equipment are important to determine production rates, calculate logging costs and locate operating inefficiencies. However, using present time study techniques, they are also costly and time consuming to complete. This project will develop a new data gathering and storage technique using the HP-75 portable computer to...
Resource Type:: Capstone Project

Creator:: Burditt, Audrey Lynn
Abstract:: The use of partial cutting in the western conifers has become popular in the last decade. This has resulted in an increase in the amount of damage to the residual stand due to skyline logging. The purpose of this study is to provide models to predict the percent of a...
Resource Type:: Capstone Project

Creator:: Bodenhausen, Craig
Abstract:: This paper describes a mathematical formulation and computer programs for use on hand-held programmable calculators to analyze the load carrying capacity of skyline systems, including the effects of log drag. The actual physical characteristics of the load and the ground geometry are used in the analysis of the payload capacities...
Resource Type:: Capstone Project

Creator:: Artley, Richard James
Abstract:: This paper describes a computer program developed for the Hewlett Packard 9830, which analyzes and computes costs and engineering data for paper plan timber harvest road networks. The program will accept up to 110 road segments. Each segment is analyzed individually based on digitized data from a contour map and...
Resource Type:: Capstone Project

Creator:: Starnes, Lawson W.
Abstract:: This paper shows how ten easy-to-use linear skyline thinning production rate equations were obtained by transforming existing but more cumbersome turn time equations using the THIN simulation model [11). The equations provide reasonable approximations of delay-free hourly production for several cable yarders operating skyline thinnings under a variety of conditions....
