Notes
Elements and Performance Criteria

  • 1.1 Review work plan and check where required with appropriate personnel.
  • 1.2 Identify type and quantity of trees to be tree jacked and assess activities for safety and environmental protection practices.
  • 1.3 Select appropriate equipment and check for operational effectiveness in line with manufacturer's recommendations.
  • 1.4 Plan tree jacking activities in line with workplace health and safety (WHS) procedures and work plan.
2. Assess and plan tree jacking
  • 2.1 Assess environmental conditions and use outcomes to plan felling of each tree.
  • 2.2 Monitor location and movement of other personnel and modify work to ensure safety.
  • 2.3 Assess tree, location and stability for conditions likely to affect safety of tree jacking activities.
  • 2.4 Visually assess tree for defects, grade and recovery status.
  • 2.5 Select escape route, clear route and growth around tree manually or mechanically.
  • 2.6 Assess fall direction and allowable degree of error, considering hang ups, damage, extraction constraints and available open space.
  • 2.7 Plan cutting sequence to control direction of fall and minimise damage to tree and surrounding environment; communicate to others.
  • 2.8 Mark trees too dangerous to fell safely and refer to appropriate personnel.

  • 3.4 Make jacking slots to provide for placement of tree jacks in line with planned falling direction.
  • 3.5 Adjust cutting technique and use tree jacks to control movement and direction of tree being felled.
  • 3.6 Complete felling and use planned safe exit route in line with safety procedures.
  • 3.7 Monitor ground movement of tree; assess and clear trees that hang up.
  • 3.8 Record and report tree jacking process and equipment faults to appropriate personnel.
