Mining operations on Vancouver Island — from aggregate quarries in the Comox Valley to gold prospects near Zeballos — push equipment to its structural limits daily. Crushers, conveyors, screening plants, loaders, and haul trucks operate in abrasive, high-impact environments where metal fatigue and wear are constant adversaries. Preventive maintenance is not optional — it is the difference between scheduled downtime and catastrophic failure.
Structural Inspection Schedule
Every piece of mining equipment should receive a thorough structural inspection on a regular schedule. Weekly visual checks should look for new cracks, loose bolts, and leaking hydraulics. Monthly inspections should include detailed examination of high-stress areas: boom and arm pivot points, frame welds, bucket and attachment connections, and crusher jaw mounts. Quarterly inspections should involve measurement of wear plates, liner thickness, and critical dimensions.
Common Failure Points
Understanding where mining equipment typically fails helps focus inspection efforts. Crusher frames develop cracks at mounting bolt locations and jaw pivot points. Conveyor frames fatigue at splice joints and idler mounting points. Bucket cutting edges and wear plates thin to the point of breakthrough. Excavator and loader booms crack at the pin boss welds. Screen decks and vibrating equipment loosen fasteners and crack welds from constant vibration.
Wear Plate and Liner Management
Wear plates and liners are sacrificial components designed to protect structural steel underneath. When they wear through, the structural members underneath suffer rapid damage. We supply and install AR400 and AR500 wear plate for mining equipment, custom cut and fitted to your specific application. Keeping wear plates in good condition is one of the most cost-effective maintenance practices in mining.
Build a Relationship with Your Fabricator
Having a fabrication and repair shop that knows your equipment pays dividends when repairs are needed. We keep records of previous repairs, know the weak points of your specific machines, and can pre-stage materials for anticipated maintenance. T & C Fabrication serves mining operations across Vancouver Island. Call Ted at 250-202-1643 to schedule a maintenance inspection or discuss your mining equipment needs.
