Technodiversity Glossary

• Combination of harvester and forwarder: forwarder with harvester head at the tip of the crane
• Working like harvester, but feeding logs directly into the basket until full, then forwarding and unloading

Functiogram

• 1 machine, 1 driver, 1 times moving  to the felling site
• No access for the harvester – 1 turn less on the skid road (but harvester is not important when followed by forwarder)
• Cleanest load - no contamination

• While processing is forwarder not productive, while transporting is the heavy and expensive harvester head unproductive
• Possible lower payload/tare ratio?

• Only in areas where there is few harvesting mass (like singular windthrows, beatle trees) so that machine can finish its job at the first access

Example:

• machine costs without personal costs: 250,00 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 1
• in total: 285,00 Euro/h
• regression line minutes per tree
  • b₀ = 0,5
  • b₁ (tree volume) = 2,3
  • b₂ (skidding distance) = 0,01

Social suitability:

• S-class: unloading of short wood at forest road -> S4
• E-class: advanced machine work, moderate -> E4
