Unit of competency details

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

This section describes the skills and knowledge required for this unit.

Required skills 

Specific skills are required to achieve the performance criteria in this unit, particularly for the application in the various circumstances in which this unit may be applied. This includes the ability to carry out the following as required to conduct bucket-wheel operations:

• apply legislative, organisation and site requirements and procedures
• apply operational safety requirements
• access, interpret and apply technical information
• apply hand-eye coordination
• apply procedures for working at heights
• apply diagnostic techniques
• use relevant hand tools
• apply environmental constraints
• apply equipment records maintenance requirements
• apply required procedures for the dispose of environmentally sensitive fluids and materials
• apply chemical and fuel safety measures

Required knowledge 

Specific knowledge is required to achieve the Performance Criteria of this unit, particularly its application in a variety of circumstances in which the unit may be used. This includes knowledge of the following, as required to conduct bucket-wheel operations:

• site and equipment safety procedures
• site operational procedures
• equipment characteristics, technical capabilities and limitations
• operational procedures
• site environmental requirements and constraints
• hazard identification and response procedures

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 

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 worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:

• knowledge of the requirements, procedures and instructions for conducting bucket-wheel operations
• implementation of requirements, procedures and techniques for the safe, effective and efficient completion of bucket-wheel operations
• working with others to undertake and complete bucket-wheel operations that meet all of the required outcomes
• consistent timely completion of bucket-wheel operations that safely, effectively and efficiently meet the required outcomes

Context of and specific resources for assessment 

• This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.
• The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.
• Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.
• Aboriginal people and other people from a non English speaking background may have second language issues.
• Assessment of this competency requires typical resources normally used in the work environment. Selection and use of resources for particular work sites may differ due to site circumstances.
• Where applicable, physical resources should include equipment modified for people with disabilities.
• Access must be provided to appropriate learning and/or assessment support when required.

Method of assessment 

This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:

• written and/or oral assessment of the candidate's required knowledge
• observed, documented and/or first hand testimonial evidence of the candidate's:

• implementation of appropriate requirement, procedures and techniques for the safe, effective and efficient achievement of required outcomes
• consistently achieving the required outcomes

• first hand testimonial evidence of the candidate's:

• working with others to undertake and complete bucket-wheel operations
