Mining Engineering Calculators
Practical, client-side engineering and operational calculators for mining maintenance teams — estimate downtime cost, plan pin and bush line boring repairs, size hydraulic cylinders and verify bolt torque. No data leaves your browser.
Downtime Cost Estimator
Estimate the production cost of equipment downtime to quantify the value of fast line boring, machining or field service. Figures are indicative — contact NLC Engineering for a tailored response.
Pin & Bush Repair Allowance
Calculate the oversize pin diameter, required bush bore and material removal for a line boring pin and bush repair. Useful for planning an in-situ line boring job on loaders, excavators and haul trucks.
Hydraulic Cylinder Force
Calculate the extend and retract force of a hydraulic cylinder from bore, rod diameter and pressure. Useful for sizing cylinders, verifying hydraulic pulls and assessing component repair requirements.
Bolt Torque & Preload
Estimate tightening torque and preload for a metric bolted joint using the standard T = K·F·d relationship. Indicative only — always verify against OEM specifications for critical assemblies.
