Description
This unit of competency covers the process of rigging on the ground and defines the standard required to: select and examine ropes and equipment; select and use a rigging system as directed; assist with tree operations; use established methods of rigging and communicate effectively with work crew.
Notes
Elements and Performance Criteria
1. Assist in the preparation of the work site
- 1.1. Assistance is provided to confirm the location of worksite and location of the correct tree as per the scope of works.
- 1.2. Required site permits and licences are obtained.
- 1.3. Assistance is provided to a qualified arborist in the inspection of the tree for structural defects.
- 1.4. Site hazards are identified; risks assessed and reported to the supervisor or qualified arborist.
- 1.5. The work zone is confirmed with the work crew and is monitored.
- 1.6. Traffic management plans for the work site are implemented as instructed.
2. Prepare for rigging
- 2.1. Rigging method is discussed by the work crew and determined by supervisor or qualified arborist.
- 2.2. Rigging method confirms the risk controls selected in accordance with established and documented low risk work methods.
- 2.3. Appropriate rigging equipment is selected as directed.
- 2.4. Rigging equipment is examined, assembled, installed and checked for equipment defects.
3. Perform rigging operations
- 3.1. Communication with the person cutting is commenced, instructions are received and appropriate responses are provided.
- 3.2. Appropriate knots are selected and tied as required.
- 3.3. Rigging system and environmental conditions are monitored.
- 3.4. Rigging is adjusted as instructed.
- 3.5. Load is controlled and raised, lowered or re-directed as instructed.
- 3.6. Load is disconnected from the rigging system and rigging equipment is checked.
- 3.7. The appropriate component of the rigging system is returned to the person cutting.
4. Complete rigging operations
- 4.1. The load is removed from the drop zone.
- 4.2. Rigging operations are completed as per scope of works.
- 4.3. Tools, equipment and machinery are cleaned, checked, and replaced if faulty or worn, and stored.

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:
select and examine ropes and equipment;
select and use a rigging system as directed;
assist with tree operations;
use established methods of rigging
communicate effectively with work crew.
Context of and specific resources for assessment
Competency requires the application of work practices under work conditions. Selection and use of resources for some work sites may differ due to the regional or enterprise circumstances. There is an industry expectation for refresher training and assessment.
