Experimental research of fuel consumption by port mobile cranes

Abstract

Modernity puts forward more stringent requirements for the Ukrainian port industry for transshipment equipment to ensure their operational reliability and minimize costs. This is especially true for truck cranes, the number of which in ports is growing every year, and fuel costs account for a significant share of the cost of work. Therefore, improving the fuel efficiency of truck cranes is an urgent task. The existing methods of fuel consumption regulation for truck cranes take into account only the nominal and maximum load capacity, ignoring the actual weight of the cargo being transported. 22 automobile cranes with a lifting capacity of 25 tons, which are operated in seaports in winter and summer periods for 10-17 years, were selected as research objects. All cranes passed a timely technical inspection and were recognized as serviceable. The study was conducted for two years, during the summer and winter periods. The resulting data for each tap was processed using MS EXCEL at the end of the shift. The truck cranes performed identical operations of cargo transfer to ships. Experiments have shown that fuel consumption increases during the winter season compared to the summer season. The level of fuel consumption is affected by the qualification of the crane operator and the technical condition of the crane mechanisms. The analysis showed that diesel fuel is consumed at a rate of 13-14% less than gasoline. To cut down on how much fuel the crane uses, focus on training the people who use it and keeping the crane well-maintained
