  • Determination of the Bucket Wheel Drive Power by Computer

    Starting from the general principles of material cutting, with applicability to coal and overburden excavation using bucket wheel excavators (BWEs), this paper proposes another method for calculating the drive power of the bucket wheel excavator by computer modeling. This approach required two steps. In the first step, the volume of the excavated material for one slewing movement of the boom

  • 3. CALCULATION OF MACHINE RATES

    3.1 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.

    Apr 08, 2019 · Backhoe excavators are another nearly ubiquitous piece of equipment in construction, landscaping and mining. Often confused with standard excavators, backhoe excavators are backhoe loaders with an excavator boom attachment on the back of the machine. On the front of the backhoe is a large bucket or blade used to push, level and move soil and other materials.
