PMBPROD340A
Cure heavy off-the-road tyre repairs

Assessment tool

Version 1.0
Issue Date: April 2024


This competency is typically performed by operators applying knowledge of materials, knowledge and basic understanding of the tyre design, and product purpose and processes to the curing of repaired tyres. It also requires the use of some discretion and judgment to recognise and resolve a range of problems.

This unit covers curing using pressure curing systems, such as ‘Monarch’ (air bag) and ‘Thermopress’. For autoclave curing see PMBPROD375B Vulcanise products using an autoclave.)

This unit should be interpreted in line with AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair – Tyres.

This unit of competency covers the skills and knowledge needed to cure repairs to tyres defined by AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair – Tyres (or its authorised replacement) or similar tyres.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

Critical aspects for assessment and evidence are:

tyre injury/repair is identified and appropriate action for curing determined

consistent application of curing standards

safety procedures are always followed.

Context of and specific resources for assessment

Assessment will occur on an HOTR tyre repair facility. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

Method of assessment

Competence in this unit may be assessed:

by observation over a range of tyre curing procedures undertaken in the workplace

in a situation allowing for the generation of evidence of the ability to respond to problems

by using a suitable simulation and/or a range of case studies/scenarios

through a combination of these techniques.

In all cases it is expected that appropriate practical/simulation assessment will be combined with targeted questioning to assess the required knowledge, and theoretical assessment will be combined with appropriate practical/simulation or similar assessment.

Guidance information for assessment

Assessment processes and techniques must be appropriate to the language, competency and safety requirements of the site and consistent with workplace systems or procedures.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

using pressure curing systems according to the machine manufacturer’s recommendations

reading instrumentation

communicating effectively

working safely in accordance with operational requirements and safe systems of work

reading and interpreting typical product specifications, job sheets and material labels as provided to operators

writing to the level of completing workplace forms and production reports

Required knowledge

Required knowledge includes:

organisational procedures

heavy off-the-road (HOTR) tyre construction, bias and radial

methods of identifying lug/position identification

tyre repair curing methods

hazards and hazard controls associated with HOTR tyre repair curing

repair material and supplier repair recommendations

electrical equipment operation and safety

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.

Tyre securing methods

Tyre securing methods may include, but are not limited to:

mounts and stands

chocks

wall or floor mounted frames, manually, electrically or hydraulically operated

Location of repairs

Repairs may be undertaken to the:

tread or crown, including steel components

shoulder

sidewall

bead area

liner

body cords

Curing equipment components

Curing equipment components may include, but are not limited to:

heat pads

size and shape of air bags (for a Monarch system)

contours (for a Thermopress system)

hydraulic equipment operation

pneumatic equipment operation

compressor operation

Packing

Packing includes, but is not limited to:

tread voids

flow blocks

vent supports

Tread voids are the space between the lugs on the tread. Packing is typically done on voids adjacent to a repair.

Cure cycle

Ensure that the repair has completed its required cure cycle and ensure that the temperature has been reduced to the manufacturer’s recommendations, then release pressure.

Standards

Standards may include, but are not limited to:

AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair – Tyres

Rubber Manufacturer’s Association of America (RMA)

Supplier standards, such as technical data sheets and manuals

internal organisational standards

Procedures

Procedures may be written, verbal, computer-based or in some other form. They may include but are not limited to:

all work instructions

standard operating procedures

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant

good operating practice as may be defined by industry codes of practice

Procedures would be expected to comply with any relevant government regulations.

Paperwork

Paperwork may be paper or electronic-based.

Appropriate action

Appropriate action includes but is not limited to:

determining problems needing action

accessing and applying relevant technical and plant data

applying appropriate problem solving techniques to determine possible fault causes

rectifying problem using appropriate solution within area of responsibility

following through items initiated until final resolution has occurred

reporting problems outside area of responsibility/ability to designated person

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
