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. |
Hazards | May include but not limited to: ground stability (e.g. ground condition, recently filled trenches, slopes) overhead hazards (e.g. powerlines, service pipes) traffic (e.g. pedestrians, vehicles, other plant) insufficient lighting environmental conditions (e.g. wind, lightning, storms, etc.) other specific hazards (e.g. dangerous materials) |
Hazard control measures | Refers to the systematic process of eliminating or reducing the risk to personnel and property through the application of controls It includes the application of the hierarchy of control, the six-step preference of control measures to manage and control risk: 1 elimination 2 substitution 3 isolation 4 engineering control measures 5 using safe work practices 6 personal protective equipment |
Appropriate standard | May include: codes of practice (mobile crane) legislation Australian standards manufacturer's specifications industry standards (where applicable) |
Associated personnel | May include but not limited to: riggers doggers |
Appropriate | May include but not limited to: crane capabilities environmental conditions (e.g. wind, lightning, storms, etc.) |
Crane | May include a boom or jib, which is capable of being slewed (over 100 tonnes capacity) The slewing mobile crane over 100 tonnes classification encompasses the requirements for the slewing mobile crane up to 100 tonnes classification |
Communication method | May include but not limited to: verbal and non-verbal language written instructions signage hand signals listening questioning to confirm understanding appropriate worksite protocol |
Signage and labels | May include but not limited to: crane data plates/labels load charts crane decals control labels |
Procedures | May include but not limited to: manufacturer's guidelines (instructions, specifications or checklists) industry operating procedures workplace procedures (work instructions, operating procedures, checklists) |
Controls | May include but not limited to: luffing levers hoisting and lowering levers slewing levers including brake boom extension levers (where fitted) |
Service logbook | May include but not limited to: any logbook service book history record system where the service and maintenance history is kept |
Crane safety devices | May include but not limited to: horns/sirens audible and visual reversing devices operator restraint devices lights |
Communication equipment | May include but not limited to: two-way radios whistles bells buzzers NB: where radio communication equipment is used the transmitting frequencies of the equipment must be selected to prevent interference to or from other radio equipment being used in the vicinity of the crane |
Ground suitability | May include but not limited to: rough uneven ground backfilled ground soft soils hard compacted soil rock bitumen concrete |
Stability | May include but not limited to: deploying outriggers establishing correct size plates or packing correctly positioning plates or packing |
Crane configuration | May include but not be limited to: boom/jib fly-jib counterweights |
Hazard prevention/control measures | May include but not limited to: safety tags on electrical switches/isolators insulated powerlines safety observer used inside exclusion zone disconnected power traffic barricades and control pedestrian barricades trench covers movement of obstructions personal protective equipment adequate illumination |
Test lift | The load is lifted just clear of the lifting plane to allow for checks to be safely made in consultation with associated personnel to ensure that: near capacity loads do not overload the crane loads of unusual shape or weight distribution are correctly slung load measuring equipment can be used to verify the calculated weight of the load all crane equipment is functioning properly adjustments to the slinging can be made in a safe manner |
Relevant crane movements | May include but not limited to: telescope in and out jib up and down slew jib operation of outriggers/stabilisers raise and lower hoist travel |
Communication signals | May include but not limited to: stop - hand stop - whistle hoist up - hand hoist up - whistle hoist down - hand hoist down - whistle luff boom down - hand luff boom down - whistle luff boom up - hand luff boom up - whistle telescope out - hand telescope out - whistle telescope in - hand telescope in - whistle slew left - hand slew left - whistle slew right - hand slew right - whistle travel - hand |
Unplanned and/or unsafe situations | May include but not limited to: failure/loss of control (e.g. brakes and steering) failure of equipment (e.g. hydraulic system) environmental conditions (e.g. wind, lightning, storms, etc.) |
Planned route | May include but not limited to: unusual or difficult terrains obstacles or obstruction |
Best mobile practice | May include but not limited to: minimum speed gentle acceleration and braking (to minimise load swing) minimum boom/jib length carrying the load near to the ground surface boom/jib in line with the crane boom/jib as low as possible load faces uphill use of handheld taglines |
Shut down | May include but not limited to: retracting boom/jib retracting hoist rope and hook block positioning/securing boom/jib for transport retracting outriggers/stabilisers idling engine to stabilise temperature turning off engine (where applicable) removing key from ignition (where applicable) locking and securing cabin (where applicable) securing crane for travel |
