The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |

Appropriate personnel may include: | supervisors suppliers clients colleagues managers |
Logs are to include: | the finished product or trunk of a tree after trimming and cross cutting has occurred and may be: hardwood or softwood for production or non-production purposes |
Environmental protection measures may include: | ground growth canopy general forest lean wind speed and direction fallen trees density of trees ground slope soil and water protection ground hazards and obstacles contingencies for modifying operations during wet or other adverse weather conditions |
Equipment may include: | yarders (mobile and static, with one or more operational drums) rigging equipment and is to include: procedures for equipment lock-out such as protecting operators and co-workers from accidental injury by isolating the machine |
Yarder | is the crane-like vehicle which winches the logs from the felling site to the landing using a cable system methods include: inspecting and modifying rigging pulling logs from the cutting area to the landing controlling speed, braking, drums, positioning of chokers and manoeuvring of obstacles |
Cable operations may include: | activities covering a full range of species, log sizes, falling and retention densities, slope taking into consideration environmental requirements use of cable systems including high lead (no skyline), standing skyline and a running skyline with hauling both uphill and downhill logs attached optimising payload without exceeding the lift or haul capacity of the system |
Communication may include: | verbal and non-verbal language hand or other agreed signals eye contact with other operators or personnel active listening questioning to clarify and confirm understanding use of electronic communication devices |
Landing: | is the location where the yarder is positioned to receive the logs |
Outriggers | are the hydraulic feet or pads put out by the yarder to level the operating base and securely set the yarder in place |
Tower | is the crane like raised tower which the cables operate from to provide height for extraction of logs. |
Spars | are the out-posted erections which provide elevation for the cables some distance from the yarder tower |
Line shifts | are the moving of rigging lines from one area of operation to a new area |
System components may include: | ropes blocks chains shackles |
Maintenance may include: | regular checks of the tower and components diagnosis and repair of damaged components maintenance of fluid levels and air pressures refuelling and general maintenance |
Guylines | support the tower or spar and other rigged erections to provide stability and strength during operation |
Blocks | are pulleys cased in a block which aid in changing the direction of a force and to increase power or speed in conjunction with running cables |
Pre start-up checks | are conducted to ensure: equipment has been set up correctly the systems are performing accurately and operating to optimum performance |
Signals may include: | whistle signals air horns visual signals two-way radio talk-e-tooter signals other audible signals |
Mechanical systems are to include: | haul speed and engine power yarder operational temperatures and pressures |
Tension | is the level of strain or pressure upon cables and ropes |
Hang ups | logs which are in the process of being extracted, become entangled or snagged with other objects, usually other standing trees |
Obstacles may include: | standing trees stumps rocks ground projections |
Rigging slinger role includes: | deciding what logs to take out first and being responsible for getting the logs to the landing without breaking them directing the choker setter personnel in hooking up logs transmitting signals to and from the yarder |
Bridling | is the cable or chain extensions which assist with choker setting |
Chasers | direct the landing of logs in conjunction with the yarder and unhook the logs at the landing site |
Records and reports may include: | yarder operations extraction methods tree type size length diameter inspection quality outcomes hazards incidents equipment malfunctions and may be: manual using a computer-based system or another appropriate organisational communication system |
