The remainder was repositioning time, which was, indeed, nearly equal, with an average difference of only 15 seconds between the two machines in each run.The net results of this exercise were twofold: first, we could compare the working speeds of the machines as they completed their various dirt-moving tasks, thus giving an indication of their relative production capacities; second, by using fuel-consumption data reported from the machines’ monitor panels, we had the information to compare fuel efficiency.According to Komatsu, the monitor’s electronic intelligence has the capability to analyze fuel consumption based on a machine’s activity in a specified time period and to report a projected gallons-per-hour rate.For example, although the actual fuel-consumption rate would have been different for each specific activity in the multiple-application evaluation (ranging from a high for traveling to a low for idling), the system’s logic, says Komatsu, can report an average hourly consumption rate for the mix of activities, assuming that the system was reset to zero at the beginning of the evaluation.For the multiple-application evaluation, we reasoned that since both machines did essentially the same amount of work, then comparing fuel used would provide an insight into fuel efficiency.

P mode – Power or work priority mode has low fuel consumption, but fast equipment speed and maximum power. We have a veteran operator who wasn’t a fan of the hybrid, because he thought it didn’t have the power of the PC200. Type 8 is for Mode P) Based on the hybrid’s performance, Peters subsequently made a rental-purchase agreement on an HB215LC-1, which currently remains in his fleet.Peters admits he’s the kind of operator who continually refines his technique to get the best from any machine—and that he has taken a special interest in the hybrid.“I have almost two seasons tweaking operation on the hybrid,” says Peters, “and I’ve found that making a few simple changes in technique, compared to the PC200, makes a positive difference in performance.” According to Nájera, Komatsu’s first hybrid excavator, the PC200LC-8 Hybrid, was introduced mid-2008 in Japan. 0000036849 00000 n Well maintained, fuel efficient Excavator for hire in and around South Africa. 0000036337 00000 n 0000029034 00000 n 5t Mini Digger for Sale, Find details about China Small Excavator 7. This number will stay closer to the 8 gallon per hour range is used conservatively. The machines were shut down between loads in order to eliminate idling from the fuel calculation.To summarize, we found the HB215LC-1 to be slightly more productive, the result of a faster average cycle time and a slight edge in average bucket fill (amount of material loaded per bucket). 0000007783 00000 n %PDF-1.7 %���� 0000023990 00000 n “We can now substantiate that claim, because some of the early machines are approaching 14,000 hours of service. 0000023898 00000 n 0000036337 00000 n LT Earth Movers provides top quality operators that have been trained and are medically fit to operate the Excavators.Excavators are a powerful piece of machinery that make light work of any construction and clearing jobs. 0000036706 00000 n Table 2 Comparison of fuel consumption and fuel consumption efficiency PC200-8 PC200-7 Work amount 100 100 Damp loading Fuel consumption 90 100 Fuel economy 111 100 Ditch digging Work amount 104 100 Fuel consumption 90 100 Fuel economy 116 100 (Figures are shown basing Mode A of Type 7 as 100.

A thumbnail summary of the data showed the HB215LC-1 to be 21 percent more fuel efficient (performing the same amount of work as the PC200LC-8, but using 21 percent less fuel).
