Why it matters

Key Benefits

Reduced Unplanned Downtime on Hydraulic Cylinders

Condition monitoring detects developing faults in seals, rods, and barrel bores weeks before failure occurs in remote high-dust and heavy-vibration environments, enabling planned repairs during scheduled outages.

Extended Hydraulic Cylinders Component Life

Addressing root causes of wear on seals, rods, and barrel bores extends service intervals and reduces the frequency of major overhauls on Hydraulic Cylinders in Mining operations.

Lower Total Maintenance Cost

Shifting from reactive to condition-based maintenance on Hydraulic Cylinders reduces emergency repair costs, overtime labor, and collateral damage to adjacent components.

Context

Challenge & Approach

The Reliability Challenge

Haul truck suspension cylinder seal failures cause ride instability that grounds trucks for repair and reduces fleet availability. Shovel boom cylinder rod scoring from mine dust accelerates seal wear and creates progressive leakage. Crusher CSS adjustment cylinder drift allows discharge setting variation that affects product sizing. Dozer blade cylinder seal failures reduce blade force and limit material handling capability on mine benches.

Our Approach

We measure cylinder drift rates under load to quantify piston seal bypass on critical equipment. Rod surface profilometry identifies scoring from dust contamination. External leakage tracking monitors rod seal degradation between service intervals. We correlate cylinder condition with equipment production data to prioritize cylinder rebuilds based on fleet utilization impact, aligning maintenance with planned equipment service windows at mine site maintenance facilities.
