Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Prepare for rigging slinger operations |
1.1. Applicable Occupational Health and Safety (OHS), environmental , legislative and organisational requirements relevant to monitoring log recovery (rigging slinger) are identified and followed 1.2. Work order is reviewed and checked with appropriate personnel 1.3. Type and quantity of logs to be extracted is identified and assessed for safe working conditions and environmental protection measures 1.4. Equipment is selected appropriate to work requirements and checked for operational effectiveness in line with manufacturer's recommendations 1.5. Rigging slinger and cable operation activities are planned in line with site procedures 1.6. Communication with others is established and maintained in line with OHS requirements |
2. Plan breakout |
2.1. All work is conducted in line with work order, environmental and OHS requirements 2.2. Audible or visual signal system to be used is identified 2.3. Site , the rigged cable system and landing are assessed for slope, haul line, backline, lift capacity and landing chute 2.4. Obstacles to extraction operations are identified and avoidance plan is developed 2.5. Logs to be recovered using current and future haul lines are identified 2.6. Extraction pattern for the typical number and size of logs to be hauled on each turn is planned using assessment information 2.7. Line shifts are planned during hauling, future rigging points established and rigging is prepared |
3. Direct hook up of logs |
3.1. Specific logs for next turn are selected prior to return of butt rigging in line with planned operation 3.2. Stability of logs to be extracted is assessed and precautions are taken against movement in line with the logging code of practice 3.3. Choker setters are directed to prepare and hook up logs ready for extraction 3.4. Haul signals are given when all persons are clear from logs and bight of ropes using signalling systems in line with the cable logging code of practice 3.5. Log movement is monitored and stopped for corrective action when difficulties occur 3.6. Control of movement is maintained using signalling systems until payload is in clear sight of the yarder operator 3.7. Breakout processes and equipment faults are recorded and reported in line with site procedures |
4. Assist with line shifts |
4.1. All logs to be hauled with existing line position are cleared before line shift is initiated 4.2. Stumps are notched in line with code requirements for the rigging method to be used 4.3. Slack is pulled in on all lines prior to release of existing rigging 4.4. Rigging components are dismantled from the existing line, checked and set up on the new line 4.5. Obstructions which may cause binding or damage during hauling are moved as required 4.6. Spars, tail trees and intermediate supports are rigged in line with site procedures |

Evidence Guide
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 |
A person who demonstrates competency in this unit must be able to provide evidence that they can safely and efficiently monitor log recovery (rigging slinger) operations to recover felled logs within organisational requirements |
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 and satisfy all of the requirements of the elements of this unit and include demonstration of:
|
Context of and specific resources for assessment |
|
Method of assessment |
|
