The effects of swinging and sorting with a skidder on yarding and loading efficiency in small diameter Douglas-fir

Creator:

McIntire, John Charles

Abstract:

This study evaluated the impact of using a rubber-tired skidder to keep the landing clear by sorting and decking the logs along the road prior to loading by a self-loading truck. The evaluation was accomplished through detailed time studies conducted on a Koller K-300 yarder, a Crown Super 3000 self-loader,...

Tension relationships for steel cable on notched stumps

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...

Load-deformation characteristics of multiple stump anchor systems

Creator:

Toupin, Richard C.

Abstract:

This paper documents the development of a model which determines multiple stump anchor system displacement as a response to skyline load for four anchor rigging configurations: 1. Series multiple, 2. Tieback, 3. Elevated tieback, and 4. Equalizer block. It also documents the field testing of four two stump anchors rigged...

Load bearing capacity of alder, spruce and hemlock tail trees

Creator:

Pugh, Edwin V.

Abstract:

This paper presents an evaluation of the cable loading support capacity of red alder, Alnus rubra Bong., Sitka spruce, Picea sitchensis (Bong.) Carr, and western hemlock, Tsuga heterophylla (Raf.) Sarg., tail trees. Capacity is measured in terms of combined stress resulting from compression and bending, rather than the traditional methods...

Capstone Project
Engineering analysis of forces created in two tree intermediate supports during multi-span logging

Creator:

Fodge, Francis W.

Abstract:

An analysis of forces on two tree intermediate supports is presented. The analysis is in two parts: The maximum force that the support jack will experience. The movement and forces created in the two tree support by the skyline and carriage. The maximum force on the support jack occurs when...

A method of selection of cable harvesting machines for Vermont

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...
