Functiogram

Advantages

• High productivity, low price (if fully utilized)
• Low danger, low ergonomic injuries

• Good for coniferous trees with straight stems
• Limited with bigger, crooked or broadleaves trees

• On accessible skidroads
• Coniferous trees, younger broadleaves trees
• Distance of skid roads > 2x reach of crane

Economic suitability

Example:

• machine costs without personal costs: 160,00 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 1
• in total: 195,00 Euro/h
• regression line minutes per tree
  • b₀ = 0,5
  • b₁ (tree volume) = 2,0
