Complete Refurbishment of Wiring Harnesses on Mining Equipment
Overview
A large piece of earthmoving equipment operating in a demanding mining environment required a full electrical refurbishment to improve reliability, safety, and long-term performance. The project involved the removal of ageing braided wiring harnesses and the design, manufacture, and installation of new heavy-duty electrical systems.
The refurbishment utilised custom braided wiring harnesses locally manufactured in Perth and installed on-site by an experienced heavy-duty auto electrician, delivering a robust, mining-ready electrical solution.
The Challenge
The machine was operating with original braided wiring harnesses that had deteriorated over time due to harsh operating conditions, including:
- Prolonged exposure to heat, vibration, dust, and moisture
- Brittle insulation and chafing within loom runs
- Previous repairs and modifications, including jump wires, which compromised system integrity
As a result, the existing wiring no longer met the reliability standards required for modern mining operations, increasing the risk of unplanned downtime and ongoing maintenance issues.
The Solution
A complete end-to-end wiring harness refurbishment was undertaken, covering removal, documentation, manufacture, and installation of a new electrical system.
The scope of works included:
- Complete removal of all existing braided wiring harnesses
- Full strip-down and documentation of the original wiring layout
- Design and manufacture of custom braided wiring harnesses
- Use of abrasion-resistant braid rated for harsh mining environments
- Final installation and commissioning by qualified heavy-duty auto electricians
All works were completed as part of a comprehensive mining auto electrical services program.
Manufacture & Documentation
Prior to manufacture, the new wiring system was fully documented to ensure accuracy, serviceability, and repeatability. As a local wiring harness manufacturer based in Perth, the team produced custom looms engineered specifically for mining conditions.
Key features included:
- Custom-manufactured wiring harnesses
- Heavy-duty connectors with integrated strain relief
- Upgraded heavy-duty braid for maximum abrasion protection
- Design standards exceeding OEM durability expectations
- Suitability for long-term mining auto electrical applications
This approach ensured consistent quality, simplified future repairs, and improved long-term asset reliability.
Installation
Installation was completed on-site by a qualified heavy-duty auto electrician specialising in mining auto electrical services.
Installation works included:
- Fitment of new upgraded braided wiring harnesses
- Secure routing to eliminate chafing and vibration-related damage
- Integration with existing OEM electrical cabinets and systems
All components were selected and installed to suit heavy-duty mining applications.
The Results
Improved Reliability
- Significant reduction in electrical faults and breakdowns
- Enhanced protection against dust, heat, and vibration
- Increased confidence in overall electrical system integrity
Mining-Ready Electrical System
- Purpose-built wiring harness designed for mining conditions
- Improved durability for long-term operation
- Reduced maintenance intervention and downtime
Key Takeaway
Replacing ageing braided wiring harnesses with custom-manufactured wiring harnesses delivers a substantial improvement in reliability. When designed, manufactured, and installed by a specialist mining auto electrician, the result is an electrical system purpose-built for harsh mining environments.
This project successfully extended the service life of an older asset, delivering long-term reliability and value for the mining client.
