Get PriceTotal Cost of Ownership (TCO) is an increasingly common purchasing approach among our customers. They now consider not only purchase costs (max. 15 to 20% of total costs ), but also all future costs that machine ownership entails, such as spare parts, maintenance and repair costs, tyres and wear parts, uptime, personnel, interest rate, depreciation, insurance, taxes and fuel consumption.
Get Price3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.
