Technodiversity Glossary

Functiogram:

• It does not require to process the trees in the forest
• simple machine and procedure
• it can drag long loads
• high speed

• It requires large landings or a separate loader
  
• needs skid trail in dense stands and or on steep terrain
  
• relatively small payload
  
• high speed and many repetitive cycles are heavy on the operator
  
• aggressive on the soil (esp. crawlers in steep terrain)
  
• operator needs to leave the cab and re-enter the cab twice per cycle, unless an assistant is available to do so (uncomfortable)
  

• mountain operations
• when we are not able to run a harvester-forwarder system and want to mechanize at roadside by processor (or chipper)

Economic suitability

Example:

• machine costs without personal costs: 40,00 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 2
• in total: 110,00 Euro/h
• regression line minutes per tree
  • b₀ = 5
  • b₁ (tree volume) = 1
  • B2 (skidding distance) = 0,01

Ecological suitability

Ecograms

Social suitability:

• S-class: unloading full trees on the road -> S3
• E-class: simple machine work, heavy and dangerous -> E3
