ABSTRACT:
An improved fully mechanized sawmill is provided which is composed of structurally independent modules which are removably mounted on a platform composed of a plurality of side-by-side longerons supported horizontally on files of spaced-apart vertical piers and columns. The longerons provide horizontal stress support for the platform along the files of piers and columns perpendicularly to the cutting axis of the sawmill, and the modules mounted thereon provide horizontal stress support for the platform along the ranks of the piers and columns parallel to the cutting axis. In addition, improved mechanisms and techniques are provided for handling and selecting the sawlogs to be cut, for selecting and distributing the pieces cut therefrom according to shape and utility, and for stacking and handling the distributed pieces at preselected locations according to shape and utility. In particular, there is provided a support and coupling member which includes at least two spaced apart and upright leg bracket members joined at their lower ends by a U-shaped saddle element. The leg bracket members are adopted to carry slidably mounted pulleys, and three sets of upper arm support elements.
