Technological process design of the log yard when delivering tree-length materials of different species

Abstract

This article dwells upon process design of the log yard where logs are prepared for sawing operations, tree-length materials being of different wood species. The sawing requirements are analyzed which enable efficient and complex use of the raw materials. The necessity to form sort groups before sawing is proved as well as the importance of debarking to obtain high-quality wood chips from lumber waste. The selection of optimal hoisting and transportation equipment is considered in the paper. It also focuses on the features of the technological processes of bucking, sorting and debarking of hardwood raw materials. The paper outlines the technological process and log yard layout.
