Elements and Performance Criteria
- Prepare for hook tender operations
- Review work plan and where appropriate check with appropriate personnel.
- Identify required type and quantity of cable recovery equipment and assess for safety and environmental protection practices.
- Select appropriate equipment and check for operational effectiveness in line with manufacturer's recommendations
- Plan cable operation activities in line with workplace health and safety (WHS) procedures and work plan.
- Plan cable system layout
- Obtain and evaluate information to plan cable system layout and inspect site for hazards and factors affecting harvesting operations.
- Provide personnel with information about landing location and size, hauling boundaries, access routes and construction requirements.
- Consider code of practice, site topography, minimising system design additions and select cable system type to optimise log extraction rate.
- Identify general requirements for anchor points, backline and intermediate supports and provide instruction to fallers.
- Coordinate yarder and cable system set up
- Select rope sizes for lines in line with code of practice, yarder capacity and system design.
- Select components and rigging to meet code of practice requirements and system design.
- Inspect and install components and lines.
- Direct and assist personnel to layout lines, select anchors and position mobile backstops.
- Assess felled trees for location, size and obstructions; plan recovery extraction sequence to minimise line shifts, log and environmental damage.
- Select support trees and provide directions for rigging.
- Check unloaded and loaded system performance and calculate loads to ensure they are within system and equipment capacity.
- Monitor operations, change and communicate procedures or system design to improve safety and payload efficiency.
- Coordinate rigging of spars, towers and trees
- Check cable system plans and determine operational requirements for tower, spars and support trees.
- Ensure rigging of spars, towers and trees complies with code of practice.
- Check and select spars or support trees to be rigged, guylines and anchor points.
- Select rigging and rope sizes to meet load.
- Provide directions to check components for wear, failure or missing parts prior to rigging; identify faults and take corrective action.
- Coordinate rigging on machine towers to prepare, assemble and fit operational lines, prior to raising, in line with system design.
- Identify climbing and pass line equipment.
- Coordinate guyline positioning and rigging within location angle requirements to provide minimal difference in length and tension.
- Check system components for size, safe working load, layout, position, safety straps, joins, lead angles and operating angles.
- Coordinate line shifts and rigging modifications
- Anticipate line shifts and prepare required rigging in advance.
- Diagnose limitations of system design or positioning and plan modifications in line with code of practice.
- Monitor operations; change and communicate procedures to improve safety and payload efficiency.
- Locate new support trees, anchor points and mobile tail anchor position; assign riggers to prepare and rig in line with system requirements.
- Record and report breakout processes and equipment faults in line with site procedures.
