The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Failure analysis and evaluation process | The objective of the failure analysis and evaluation process may be to determine fault rectification measures, to effect variation in system characteristics and parameters or to enhance system performance. |
Steering and braking systems | Steering and braking systems to be covered in this unit are to include mechanical and hydraulic operated steering clutch/brake, independent drives, planetary and differential planetary, hydrostatic drive, single and multi-disc brake units. |
Transmission, steering and breaking failures | Transmission, steering and braking failures covered by this unit are to include those to mechanical, hydraulic and electrical/electronic systems, including control systems, emergency systems, directional stability, calibration/adjustment specifications, contamination, component specifications, component assembly, component damage and system modifications . Transmission, steering system and braking failures covered by this unit are to include indirect faults caused by the influence of external systems which may or may not be faulty in their primary operations |
Tracked mobile plant | Tracked mobile plant covers all mobile plant with tracked undercarriage. Included are tracked type loaders, crawler tractors tracked type plant, hydraulic excavators and face shovels, material handling machines, agricultural tracked equipment and other rural equipments. |
Transmission systems | Transmission systems to be covered in this unit are to include mechanical, power shift and automatic transmissions, clutches, torque converters, drivelines and final drive sub-systems. |
Coverage | Coverage is to include infinitely variable transmission (belt, hydraulic and planetary). |
Unit context | OH&S requirements include vehicle industry regulations, safety management systems, hazardous substances and dangerous goods code and safe operating procedures. Work is carried out in accordance with legislative obligations, Australian Design Rules, environmental legislation, health regulations, manual handling procedures and organisation insurance requirements. Work requires individuals to demonstrate research, analytical, judgement and problem-solving skills in the diagnosis of faults. |
Evaluative criteria | Evaluative criteria, sometimes referred to as success factors, detail the criteria against which the achievement of the objectives of the analysis are judged. They are to include statistically based criteria and may include other measures. |
Isolation procedures | Equipment isolation procedures are to industry and enterprise standards. |
Testing equipment | Testing equipment is to include pressure and temperature gauges, flow meters, multimeter, data readers, computer-based diagnostic systems. |
Tests | Tests to be conducted are to include system pressures, flow rates, stall testing, operating temperatures, and sensor and actuator integrity. |
Personal protective equipment | Personal protective equipment is to include that prescribed under legislation, regulations and enterprise policies and practices. |
Information and procedures | Workplace procedures relating to the use of tooling and equipment. Workplace procedures relating to reporting and communication. Manufacturer/component supplier specifications and application procedures for testing equipment and material. Manufacturer/component supplier specifications, schematics and operational procedures related to tracked mobile plant steering and braking systems. Australian Design Rules. Vehicle industry regulations. Vehicle industry publications related to emerging steering and braking system technology and technology changes. |
