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)

locking and securing cabin (where applicable)
securing crane for travel

Overview of assessment
Successful assessment of this unit meets the competency requirement of the National Standard for Licensing Persons Performing High Risk Work.
State/territory OH&S regulators have mandated the use of Assessment Instruments and Instructions for Assessment for this unit which have been endorsed by the national body responsible for OH&S matters.

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Compliance with OH&S licensing legislation.
Effectively communicate and work safely with others in the work area.
Risk assessment and management procedures (particular awareness of the risks associated with overhead powerlines/electrical cables, ground conditions, crane tipping and demolition sites).
Effectively complete the pre-operational check, positioning, stabilising, set up, operation, post-operational checks of a mobile crane including all functions to their maximum extension in the lifting and moving of loads to the safe working rated capacity of the mobile crane over 100 tonne capacity in conjunction with other associated personnel.
Appropriate mathematical procedures for estimation of loads.

Context of and specific resources for assessment
Assessment of the safe and effective application of knowledge and skill to workplace tasks (performance) must be undertaken using the endorsed Assessment Instrument.
Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace setting.
Assessors must ensure that the assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area is made available to suit the assessment and the workplace.
Assessment must occur under standard and authorised work practices, safety requirements and environmental constraints.
Assessment is to comply with relevant appropriate standard requirements.

Applicants must have access to:

Personal Protective Equipment (PPE) for the purpose of the Performance Assessment
appropriate slewing mobile crane (over 100tonne) and associated equipment in safe condition
suitable loads as specified by the endorsed Assessment Instrument
communication equipment (e.g. two-way radios, whistles, etc.)
other associated personnel to sling and direct the loads.

Method of assessment
Assessment must be conducted using the endorsed Assessment Instruments. These Instruments provide advice on their application.
The use of
Assessment may be in conjunction with the assessment of other units of competency.
Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstances, but is able to be transferred to other circumstances.

Guidance information for assessment
Further information about endorsed Assessment Instruments may be obtained from state/territory OH&S regulators.
