Application
This unit of competency describes the outcomes required to plan for and navigate the extraction or breakout of logs to the landing in a forest or forest farm setting. It requires the ability to direct choker setters, transmit signals to the yarder operator and assist with line shifts for cable logging operations.
The unit applies to job roles for monitoring log recovery including Rigging Slinger.
Licensing, legislative, regulatory, or certification requirements apply to this unit in some states & territories at the time of publication, and may differ according to jurisdiction.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. |
1. Prepare for rigging slinger operations | 1.1 Review work plan and check where required with appropriate personnel. 1.2 Identify type and quantity of logs to be extracted and assess 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 cable operation activities in line with work order. |
2. Plan breakout | 2.1 Plan and complete breakout operations in line with environmental conditions and workplace health and safety (WHS) procedures. 2.2 Identify audible or visual signal system to be used. 2.3 Assess site, rigged cable system and landing for slope, haul line, backline, lift capacity and landing chute. 2.4 Identify obstacles to extraction operations and develop avoidance plan. 2.5 Identify logs to be recovered with current and future haul lines. 2.6 Assess information to plan extraction pattern for typical number and size of logs to be hauled. 2.7 Plan line shifts during hauling; establish and prepare future rigging points and rigging. |
3. Direct hook up of logs | 3.1 Select specific logs for next turn prior to return of butt rigging in line with planned operation. 3.2 Assess stability of logs to be extracted and take precautions against movement in line with code of practice. 3.3 Direct choker setters to prepare and hook up logs ready for extraction. 3.4 Give haul signals, in line with code of practice, when all persons are clear from logs and bight of ropes. 3.5 Monitor log movement and stop for corrective action when difficulties occur. 3.6 Maintain control of movement using signalling systems until payload is in clear sight of yarder operator. 3.7 Record and report breakout process and equipment faults in line with site procedures. |
4. Assist with line shifts | 4.1 Select specific logs for next turn prior to return of butt rigging in line with planned operation. 4.2 Assess stability of logs to be extracted and take precautions against movement in line with code of practice. 4.3 Direct choker setters to prepare and hook up logs ready for extraction. 4.4 Give haul signals, in line with code of practice, when all persons are clear from logs and bight of ropes. 4.5 Monitor log movement and stop for corrective action when difficulties occur. 4.6 Maintain control of movement using signalling systems until payload is in clear sight of yarder operator. 4.7 Record and report breakout process and equipment faults in line with site procedures. |
