SP-33-34 mechanized chipping of short logs at forest road

Logs are chipped from stacks piled at the roadside. The work can be done  with any chipper, in any configurations. Chips can be discharged directly onto trucks, onto tractor- trailers or on the ground. Surge bins can also be used


Functiogram

 

Advantages
  • At the roadside, one can use very large and powerful chipper that will offer the highest productivity and lowest cost
  • Logs are the best feedstock for producing high quality chips
Limitations, thresholds
  • The roadside landing must be large enough to accommodate the chipper, the accompanying chipvan and the stacks to be chipped.
  • Stacks should not be contaminated during extraction and/or piling
Main use
  • Most chipping operations
  • Chipping is more productive if performed at a roadside landing than in the stand because the material is more concentrated and one can use a larger machine


Economic suitability

 Example:

  • machine costs without personal costs: 200,00 Euro/h
  • personal costs per person: 35,00 Euro/h
  • number of persons: 1
  • in total: 235,00 Euro/h
  • regression line minutes per tree
    • b0 = 0,1
    • b1 (tree volume) = 1,0
