An extract from Predicting the Payload Capability of Cable Loging Systems Including the Effect of Partial Suspension, USDA Forest Service, Research Paper NE-479, 1981
"Abstract
A systematic procedure for predicting the payload capability of running, live and standing skylines is presented. Three hand-held calculator programs are used to predict payload capability that includes the effect of partial suspension. The programs allow for predictions of downhill yarding and for yarding away from the yarder. The equations and basic principles involved in analyzing skyline systems for allowable payload are presented."
