The chain saw is a cutting chain machine mounted on a pivot, for pendulum motion. Two rollers with retractable bars, allow the cut-off abutments to be dropped and the log to be held, controlled by a hydraulic cylinder. A set of 4 hydraulically controlled clamping arms hold the log during cutting. The set is incorporated between two longitudinal conveyors, thus allowing after cutting, to advance only the cut log.
The circular crosscut saw is a machine equipped with a measuring system for cutting logs, to selected length. It acts via a pendulum assembly with hydraulic movement. Hydraulically operated clamping arms hold the log while cutting.
