3: Tie, dress and use knots for sectional rigging.
4: Use rigging systems to lower timber sections
5: Describe installation of a controlled speed line system to lower sections of timber - Content
- - Load mass of timber section calculations, forces on each component of rigging
- Suitable equipment and techniques for rigging; frictional devices, lowering and raising brakes, false crotches, lowering ropes, pulling ropes, speed line ropes, whoopee slings, rigging blocks, pulleys
- Hazard identification and management, codes of practice, workplace procedures
- Worksite safety and risk mitigation
- Health and Safety

- Knots for sectional rigging; running bowline, cow hitch, clove hitch, timber hitch, alpine butterfly, bowline on a bight, uses, demonstrated.
- Knots for rigging components; mid line knot, anchor attachment, timber being lowered, tensioning knot, tying and use of, demonstrated.
- Non-routine tree felling
- Lowering timber sections; attaching rigging, safe working positions, anchor points, double tie in, work position stable, safe
- Demonstrate section removal, codes of practice, workplace procedures
- Speed lines, anchor points, attaching techniques; tie rope, butt rope, cradle, suit timber sizes and line configuration.
- Lowering timber section on speed line demonstrated safely, controlled to workplace procedure. - Teaching and Learning Strategy
- Teaching and learning methods will be face to face delivery including; workshops, project based interactive tasks, with group sessions, tutorials, on-line learning, work integration, and independent research for the creation of portfolios of evidence of learning.
- Learning and Teaching Resource
- Tutorial notes, workbooks, exercises and readings, and projects.
Interactive Moodle Site - Assessment Criteria
- The weight of the overall assessment is equally distributed across learning outcomes.
The portfolio of evidence will demonstrate the achievement of the required knowledge, competencies and capabilities across all the learning outcomes.
