Description
This unit involves the skills and knowledge required to estimate/calculate load shifting requirements including carrying out required calculations, preparing estimates of loads, and interpreting graphical representations of mathematical information. Licensing, legislative, regulatory or certification requirements are applicable to this unit.
Notes
Elements and Performance Criteria
1Identify mathematical information and tools used in the workplace
  • 1.1 Dimensions and/or weights to be measured are identified from work procedures and, where applicable, work order forms
  • 1.2 Units of measurement for allowable load limits (SWL and 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 the task and process
2Estimate 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 a work task are calculated
  • 2.3 Load balance characteristics are identified
  • 2.4 The 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 the limit of accuracy of the tool
3Complete documentation using mathematical information
  • 3.1 Appropriate workplace documentation is completed using recognised symbols and mathematical terms for the work tasks
  • 3.2 Numerical information is self-checked and corrected for accuracy
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
Operations may be conducted:
by day or night
in a variety of weather conditions
Environment may include movement of:
equipment

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required knowledge and skills, the range statement and the assessment guidelines for this Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria of this unit and include demonstration of applying:
the underpinning knowledge and skills
relevant legislation and workplace procedures
other relevant aspects of the range statement
Context of and specific resources for assessment
Performance is demonstrated consistently over a period of time and in a suitable range of contexts
Resources for assessment include:
a range of relevant exercises, case studies and/or other simulated practical and knowledge assessment, and/or
access to an appropriate range of relevant operational situations in the workplace
In both real and simulated environments, access is required to:
relevant and appropriate materials and equipment, and
applicable documentation including workplace procedures, regulations, codes of practice and operation manuals
Method of assessment
Assessment of this unit must be undertaken by a registered training organisation
As a minimum, assessment of knowledge must be conducted through appropriate written/oral tests
Practical assessment must occur:
through activities in an appropriately simulated environment at the registered training organisation, and/or
in an appropriate range of situations in the workplace
