Release 1.  This is the first release of this unit of competency in the TLI Transport and Logistics Training Package.

This unit involves the skills and knowledge required to estimate/calculate load shifting requirements for a mobile crane.

It includes carrying out required calculations, preparing estimates of loads, estimating and calculating requirements for load shifting, and completing documentation in accordance with relevant state or territory authority licence/permit requirements and regulations for mobile crane operations.

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.

Not applicable.

E – Communication and Calculation.

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 

Appropriate measuring equipment, features and/or scales and units of measurement are selected to completed task and process requirements

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 and/or calculated to ensure safe weighting on pallets, trucks, platforms or other storage or transport systems

2.7 

Measuring instruments are used and read according to manufacturer instructions

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 (if appropriate)

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions can be found in the TLI Transport and Logistics Training Package Companion Volume Implementation Guide.

This unit replaces and is equivalent to TLIE3016A Estimate/calculate load shifting requirements for a mobile crane.

Release 1.  This is the first release of this unit of competency in the TLI Transport and Logistics Training Package.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all the requirements of the elements and performance criteria on at least one occasion and include:

• applying mathematical procedures to estimate load shifting requirements, including:

• addition
• division
• multiplication
• percentages and fractions
• subtraction

• applying relevant workplace procedures
• calculating safe working load (SWL)/working load limits (WLL)
• completing relevant documentation
• identifying and correctly using equipment, processes and procedures
• interpreting and following operational instructions and prioritising work
• interpreting permit or licence requirements in terms of height, weight and type of lift
• modifying activities depending on operational contingencies, risk situations and environments
• operating and adapting to differences in equipment in accordance with workplace operating procedures
• reading and interpreting mathematical scales, digital readouts, specifications and customer or workplace instructions.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all the requirements of the elements and performance criteria and include knowledge of:

• calculations for SWL/WLL
• hazard management that follows the principle of hierarchy of control
• high-risk work licence requirements
• metric and, as required, imperial measurement systems
• mobile crane applications, capacities, configurations, safety hazards and limitations
• problems that may occur during a lift and associated actions that can be taken to address these problems
• relevant regulations, permit and licence requirements for mobile crane operations
• risks and hazards involved in mobile crane operations and associated actions that can be taken to eliminate or minimise the risk
• workplace procedures concerning estimating and calculating mobile crane load shifting requirements.

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within 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 must include access to:

• a range of relevant exercises, case studies and/or simulations
• relevant and appropriate materials, tools, equipment and personal protective equipment (PPE) currently used in industry
• applicable documentation, including legislation, regulations, codes of practice, workplace procedures and operation manuals.
