Logging Cost and Production Analysis

Technoeconomic Analysis of Conventional Logging Systems Operating from Stump to Landing


Book Description

S2A technoeconomic analysis of timber harvesting systems was conducted to obtain key information for estimating long run supply trends of roundwood materials from eastern woodlands. Productivity and cost factors for six stump-to-landing systems were developed from operational data for 47 harvesting operations. Technical factors and the effects of financial considerations were also assessed. Combined with the productivity and cost factors, they provided better perception of the forces impacting long run roundwood supplies and logging contractors' business options.S3.

Cost and Production Analysis of the Bitterroot Miniyarder on an Appalachian Hardwood Site


Book Description

S2An 18-horsepower skyline yarder was studied on a steep slope clearcut, yarding small hardwood trees uphill for fuelwood. Yarding cycle characteristics sampled include: total cycle time including delays, 5.20 minutes; yarding distance, 208 feet (350 feet maximum); turn volume, 11.6 cubic feet (24 cubic feet maximum); pieces per turn, 2.3. Cost analysis shows yarding costs will range from $18.00 to $36.00 per unit, depending upon crew efficiency and yarding conditions.S3.
