A simulation of the operation of a log landing for a heli-stat airship in old-growth timber

Creator:

Gerstkemper, John C.

Abstract:

This paper discusses the development of a computer simulation program for the operation of a log landing for the proposed Helistat airship. The first part of the paper describes the time study used to develop production rates for the chasers, buckers, front-end loaders, and skidders to be used on the...

Capstone Project
Production rates of skyline, balloon, and helicopter yarding systems from gross time study analysis

Creator:

Curtis, Richard James

Abstract:

This paper describes the analysis of data from a three-year gross time study of skyline, balloon, and helicopter yarding systems operating in Western Oregon. Data collection activities were designed and supervised by the Pacific Northwest Forest and Range Experiment Station, U.S.D.A. Forest Service. The specific logging systems studied were running...
