- A hydraulic excavator was able to load a truck in 2 minutes and additional 30 seconds for the positioning of the truck. The hauling time, dumping time, and return time of the truck is about 25mins. What is the equipment utilization of the excavator if there are only eight trucks available during the loading operations? complete solutionA project consists of replacing the truck on an existing existing roadroad line involving 3000 feet of track. The old track can be removed at a rate of 70 feet per hour. The old rail ties can be removed at a rate of 200 feet per hour. The new ties can be installed at a rate of 25 feet per hour, and the installment track can be installed at a rate of 40 feet per hour. show this operation on a linear schedule. Assume that the minimum float for an activity at any location is 1 day.The following are the data of a simple summit mass haul diagram STATION MASS ORDINATE (m3) 0+000 -80 0+500 -130 Mass ordinate at initial point of the limit of free haul distance = +600 Mass ordinate at initial point of the economical haul distance = +200 Limit of Economic Haul = 450m Cost of Haul = P120.00 per cubic meter per meter station a.
