Large Wheel Loaders Vs. Cable Shovels (d89a230f-7b45-4df1-bba7-c36475eac884)

A study was conducted to evaluate the applicability of large wheel loaders (Caterpillar 994 Class) for use as primary loading equipment in open pit iron-ore operations. Field visits were made to taconite and gold mines that used large wheel loaders. Information was gathered on loader selection rationale; operation and maintenance experience; and production, availability and costs. Brief time studies were conducted to indicate machine performance and utilization. This paper summarizes the field data that was collected including an economic comparison of wheel loaders and cable shovels in an iron-ore application.
