Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills:

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents;
planning and sequencing operations;
checking task-related information;
checking for conformance to specification;
identifying sources of stored energy on mobile plant;
identifying hazardous situations/conditions and applying appropriate safety measures;
bleeding accumulators down and positioning actuators correctly;
tracing faulty components and localising using fluid power principles, procedures and safety requirements;
using equipment for testing hydraulic system component;
inspecting and testing components including hoses, pipes, actuators, pumps, valves, cylinders and rams according to procedure and using fluid power;
removing components from system;
identifying replacement pipes and hoses using catalogues or electronic media;
obtaining replacement parts using appropriate procedures;
selecting appropriate conductors and fittings from manufacturer catalogues and charts;
cutting conductors to length using appropriate tooling/machine;
assembling conductors using correct techniques;
replacing component parts correctly in system using appropriate tools and techniques;
testing and adjusting replacement components for correct operation and conformance to specifications, and;
conducting conductor assemblies using machine circuits.

Students will also be expected to demonstrate the following knowledge:

different sources of stored energy and their applications;
hazards and control measures associated with maintenance and rectification of fluid power systems, including housekeeping;
the reasons for bleeding accumulators and actuators and the hazards associated with working on pressurised systems;
the full range of hydraulic system components in a mobile plant application;

methods and techniques for tracing and localising faults;
the procedures and equipment for inspecting and testing hydraulic system components;
problems relating to faulty hydraulic system components/operation;
the specifications of each hydraulic system component;
the reasons for hydraulic components not operating in accordance with specifications;
all safety procedures and precautions;
common faults in hydraulic components;
removal methods for various components;
information in catalogues or electronic media;
procedures to obtain replacement parts;
typical conductor types and fittings their applications;
methods for cutting/assembling hoses/tubes/pipework;
tools and techniques for fitting replacement components and conductors;
the correct operation of hydraulic components and conductors;
the procedures for checking and adjusting the system;
safety measures for dismantling linear actuators;
the methods of inspection and measurement;
guides and specifications for reusable parts;
the correct procedures for fitting bearings and seals;
the sequence and procedure for reassembly of cylinder/ram;
assembly and fitting instructions;
the procedures for refitting rams, and;
the procedures for testing and verifying repairs using machine circuits and/or test rigs.

Required reading

The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Polytechnic and/or via the Polytechnic e-learning system.
