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
trolleying levers (where applicable)
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:
audible and visual 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.
Hazard prevention/control measures may include but not limited to:
safety tags on electrical switches/isolators
powerlines are insulated
safety observer used inside exclusion zone
power disconnected
traffic barricades and control/s
pedestrian controls
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 appropriate 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:
luffing
slewing
hoisting and lowering loads
trolleying.
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
trolleying out - hand
trolleying out - whistle
trolleying in - hand
trolleying in - whistle
slew left - hand
slew left - whistle
slew right - hand
slew right - whistle.
Unplanned and/or unsafe situations may include but not limited to:
failure/lose of control e.g. slew brakes, hoist drums
failure of equipment e.g. hydraulic system
environmental conditions (e.g. wind, lightning, storms, etc).
Shut Down may include but not limited to:
boom/jib raised to clear buildings and structures (where applicable)
trolleying hoist block to park position (where applicable)
retracting hoist rope&hook block
idle engine to stabilise temperature
weather vane mode
turning off engine
remove key from ignition
lock and secure cabin (where applicable)
lock and secure platform access hatch.

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
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 OHS 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 OHS matters.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
comply with OH&S licensing legislation
communicate and work safely with others in the work area
assess risks and management procedures (particular awareness of the risks associated with overhead powerlines/electrical cables, wind, etc)
operate a tower crane for the lifting and moving of loads to the safe working rated capacity in conjunction with other appropriate personnel
apply 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 tower crane and associated equipment in safe condition
suitable loads as specified by the endorsed assessment instrument
communication equipment (eg. two way radios, whistles, etc)
other appropriate 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 'simulators' in the assessment of this unit of competency is not acceptable.
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 OHS regulators.
