Examination of a yarding crane using radio-controlled, self-releasing chokers to yard mechanically felled and bunched timber. The report is one in a series on yarding techniques used in logging B.C. coastal second-growth timber. The study determined the system costs and productivity; determined the effect of turn volume and hookup times on productivity; compared choker-yarding costs and productivities with those of grapple yarding; and determined the marginal log volume for profitable yarding while using chokers. Two Madill 044 yarding cranes, rigged in different yarding configurations, were monitored at a detailed-timing level for 3 weeks in 1989 in a second-growth Douglas-fir stand near Port Alberni, B.C.
