FIELD: timber industry; cutters.
SUBSTANCE: proposed hydraulic drive of cutting member contains hydraulic pump with suction and pressure hydraulic lines, tank, hydraulic distributor to control flow of working liquid, hydraulic motor and feed hydraulic cylinder of cutting member. Hydraulic drive includes additionally second feed hydraulic drive of cutting member mechanically connected by rod with rod of first feed hydraulic cylinder of cutting member, both feed hydraulic cylinders of cutting member are of single-acting design. Hydraulic drive contains reversible hydraulic pump connected by hydraulic lines with feed hydraulic cylinder of cutting member and with check and safety valves unit. Hydraulic motor is made reversible, it is mechanically connected with shaft of reversible pump and is connected by hydraulic lines with check and safety valves unit. Coarse filter of working liquid is installed in suction hydraulic line connecting check and safety valves unit with tank. Filter with safety valves is installed in drain hydraulic line connecting hydraulic distributor and tank.
EFFECT: provision of reverse feed of cutting member and feed from side convenient for sawing, facilitated bringing saw chains cut of kerfs at wedging.
