METHOD FOR POWERED WOOD CUTTING ON FELLING SITE Russian patent published in 2003 - IPC

FIELD: forestry industry. SUBSTANCE: method involves cutting trees off swaths or/and track by means of crossing felling-bunching machine; laying cut off trees in bunches by said machine so that longitudinal axes of bunches are oriented at an angle to track longitudinal axis; crossing track by logging machine for loading and hauling formed bunches; providing piling of formed bunches by felling-bunching machine so that bunch apexes are positioned centrally of track and butt parts along track boundaries; laying subsequent two bunches, after first formed bunch, so that their longitudinal axes are arranged in parallel with one another and at an angle to longitudinal axis of first formed bunch, with butt part of first bunch and of two subsequent bunches being arranged on opposite boundaries of track; forming bunches subsequent to the latter in alternating succession according to piling of first mentioned bunch and two subsequent bunches; driving logging machine to bunches laid on track by back motion from side of track boundary, to which are oriented bunches butt parts laid onto track in the manner similar to that of first bunch formed by felling-bunching machine. Bunches are transported with their butt parts oriented forward with respect to logging machine advancement direction. EFFECT: increased efficiency and capacity of powered wood cutting, provision for conservation of undergrowth on developed swaths and optimal run loading of logging machine. 2 cl, 1 dwg
