This unit involves the skills and knowledge required to estimate/calculate load shifting requirements for mobile crane, in accordance with relevant state/territory authority licence/permit requirements and regulations for mobile crane operations.

It includes carrying out required calculations, preparing estimates of loads, and interpreting graphical representations of mathematical information.

Work is performed with limited or minimum supervision. It involves the application of routine principles, procedures and regulations to estimate/calculate load shifting requirements for a mobile crane.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

ELEMENTS

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1

Identify mathematical information and tools used in the workplace

1.1

Dimensions and/or weights to be measured are identified from work procedures and, as required, work order forms

1.2

Units of measurement for allowable safe working load (SWL) and working load limits (WLL) for load shifting are identified from crane load chart

1.3

Information presented in mathematical symbols, diagrams and pictorial representations is recognised, interpreted and used to complete workplace tasks

1.4

Measuring equipment, features and/or scales and units of measurement are selected as appropriate for task and process

2

Estimate and calculate requirements for load shifting

2.1

Appropriate methods are selected to perform calculations required to complete workplace tasks, including addition, subtraction, multiplication, division, fractions, decimals, percentages and mixed numbers

2.2

Quantities of materials and resources required to complete work task are calculated

2.3

Load balance characteristics are identified

2.4

Time needed to complete a work activity is estimated

2.5

Calculations required for weight, reach, radii, boom and jib configurations are undertaken and checked for conformity with crane load chart information

2.6

Load spread is estimated/calculated to ensure safe weighting on pallets, trucks, platforms or other storage or transport systems

2.7

Measuring instruments are read to limit of tool accuracy

3

Complete documentation using mathematical information

3.1

Appropriate workplace documentation is completed using recognised symbols and mathematical terms for work tasks

3.2

Numerical information is self-checked and corrected for accuracy

As a minimum, assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment include:

a range of relevant exercises, case studies and/or simulations

applicable documentation including workplace procedures, regulations, codes of practice and operation manuals

relevant materials, tools, equipment and personal protective equipment currently used in industry.
