Underground Hard Rock Gold Mine ‐ Central Canada

Application Type
Underground Hard Rock Gold Mine – Central Canada

Machine Type
Scoop/Loader LHD (1.5 yd.)

Tire Size & Type
9.50-20 (7.50) L5S Bias Tire

Site Conditions
Harsh underground mining conditions with rough floor including sharp rock debris, water and heat

Tire Problem
Site conditions often lead to cutting, penetrations and tearing. L5S bias tires with polyurethane (foam fill) were destroyed by underfoot conditions or urethane would revert to liquid due to heat and load which increased tire spend. Frequent underground tire changes incurred significant labor costs and lost production. On average a urethane filled L5S would only last 200 hours.

Trojan Solution
Installed Trojan HD Soft Core into a L5S bias tire.

Success / Outcome
Trojan Soft Core increased running hours by up to 300% per tire. This has dramatically decreased the customer tire and labor costs as well as increased production. The HD Soft Core has averaged 4 uses. This combined with the 300% increase in tire life has allowed the mine to achieve by far its lowest cost per hour versus any competing product.
