Description
This unit involves the skills and knowledge required to maintain mechanical signalling locking and interlocking devices in accordance with safeworking and regulatory requirements and workplace procedures, including diagnosing and correcting faults in the devices, and testing and adjusting the repaired equipment to meet workplace and manufacturers standards. Licensing, legislative, regulatory or certification requirements are applicable to this unit.
Notes
Elements and Performance Criteria
1Diagnose locking/interlocking equipment faults
  • 1.1 Out-of-specification or non-operating mechanical locking and interlocking signalling equipment /components are correctly identified through operational testing
  • 1.2 Viability of adjustments/replacements/repairs to equipment/components is correctly evaluated to ensure cost effective operations
  • 1.3 Work is planned to ensure minimum disruption to train operations and safe repair activities
  • 1.4 Support/assistance with diagnosis or repair operations is obtained through liaison with appropriate personnel
2Correct equipment faults
  • 2.1 Mechanical locking and interlocking signalling equipment and component cleaning/lubrication and adjustment is performed to specifications to ensure required level of operations
  • 2.2 Equipment and components are replaced or repaired as per operational specifications to ensure required level of operations
  • 2.3 Viability of repairs to replaced equipment/components is evaluated and equipment tagged for repair or disposed of in line with workplace requirements
  • 2.4 Liaison with or support to other personnel is maintained to ensure equipment is maintained within specification
3Test and adjust locking/interlocking equipment
  • 3.1 All locking/interlocking equipment functions are tested to ensure operational compliance with required standards
  • 3.2 Final cleaning, lubricating and adjustments to equipment are carried out to ensure operational compliance
  • 3.3 Equipment is locked/secured as specified to ensure safety and protection from elements or persons
  • 3.4 Records of repair activities are correctly completed and forwarded to appropriate personnel for use in identifying future maintenance requirements
