Our Services
Mining Equipment Maintenance
Unplanned shutdowns cost mining operations valuable time and throughput every day. We keep your primary mechanical circuits operating at peak availability through structured preventative servicing, component overhauls, and rapid fault resolution. Backed by 24/7 standby capabilities and dedicated shutdown crews, we ensure your machinery returns to full operational capacity safely and without delay.
Custom Steel Fabrication
Standard structural components rarely withstand the abrasive, high-impact environments of modern mine sites. JCA Maintenance delivers end-to-end custom steel fabrication designed, constructed, and installed to meet your exact plant specifications. Our boilermakers and certified welders manage everything from workshop preparation to seamless on-site structural assembly.
Mill Relining
Primary comminution circuits require precise lining management to protect shell integrity and preserve grinding efficiency. We provide turnkey removal and installation of metallic, rubber, and composite liners for ball and SAG mills using specialized hydraulic tooling. Our experienced crews minimize shutdown durations while adhering strictly to mine safety standards.
IsaMill Maintenance
Ultra-fine grinding circuits demand specialized mechanical expertise to maintain optimum grind fineness and energy efficiency. We offer dedicated IsaMill servicing—including precision shaft alignments, mechanical seal overhauls, disc replacements, and ceramic media reclamation. This targeted approach preserves fine-grind metallurgical performance while significantly reducing ongoing consumable costs.
Heavy Lifting & Crane Operations
Safe, reliable material handling is critical when moving multi-ton machinery and fabricated steelwork across busy mine sites. We operate an 8-ton Hino Hiab equipped with an 1100 Fassi Crane to deliver fully autonomous site transport, precision offloading, and equipment positioning. Executed by licensed riggers using certified tackle, we ensure complete logistics compliance without relying on third-party hires.
