Harvesting system objectives

Logging is the felling, skidding, on-site processing, and loading of trees or logs onto trucks. Logging systems always involves log transportation - the movement of trees, logs, or segments of logs from one point to another. By means of various modes of power, the trees,logs, or whatever are dragged, hauled, or carried out of the woods and across the roadsand byways to some end concentration point. Thus, two of the first objectives of any logging system are to prepare the trees for transportation and to transport them to the proper conversion facility. How the trees are prepared and transportedwill depend on the facility or market for which they are intended.Of course, there are other important objectives, such as moving the woodleast cost, maintaining a safe environment for the workmen, and maintaining a good working relationship with public and private agencies.

The actual work of logging involves an aggregation of man-machine components: planning, road construction, felling and bucking, yarding, loading, transportation, unloading. These components function together to achieve the transportation objective. Within the loggingsystem thereare only four major components. They are cutting, skidding or yarding, loading, and log transportation. Unloadingmight be defined as either a component of the logging system or a part of an interfacing system. At any rate, unloading has a direct impact on the log transportation component. Each logging system component can be further reduced to elements that better describe its function.
