Determination of the time norms for excavating soil with a mini excavator

Abstract

Since 2010, there has been a growing trend in the market for mini-excavators from various manufacturers. The range of manufactured equipment is increasing, as well as the technological capabilities of construction equipment are growing. At the same time, in the modern standards of Russia are no figures on the complexity of soil excavation with this type of technology. The article shows the timing of soil excavation using the example of a mini-excavator with a bucket volume of 0.03-0.04 m3. The object of the study is the amount of time the mini-excavator works on II group of soils. The timekeeping method is used to determine the operating time of a mini-excavator with a bucket volume of 0.03 and 0.04 m3. It is experimentally obtained that the norm of time for operation of a mini-excavator with a bucket volume of 0.03m3 is 5.82 mach *hours, and for a bucket volume of 0.04 m3 is 5.37 mach*hour.
