Rental of Extended Arm Excavator

　　一，防止发动机空转

　　First, prevent engine idling

　　即使是在空转，液压泵内还是会有油在循环并消耗燃料。在日常装车或挖掘过程中，中途可以较长时间停机的时候，尽量不要开着挖掘机怠速“等待”，要劳逸结合、更加省油，这是挖掘机省油诀窍之一。

　　Even when it is idling, there will still be oil circulating in the hydraulic pump and consuming fuel. In the daily loading or excavation process, when the machine can be stopped for a long time in the middle, try not to idle with the excavator "wait", to combine work and leisure, more fuel-efficient, this is one of the excavator's oil-saving tricks.

　　二， 防止重载失压

　　2. Preventing Heavy Load Voltage Loss

　　当挖掘的沙土或石块负荷过重时，即使拉动操纵杆作业机械也无动作，而陷入失压状态。“一口气吃不了大胖子”这个道理大家都清楚，一铲子不了的问题，可以分为两下来，否则既费机子，又耗油，就得不偿失了。

　　When the load of excavated sand or stone is too heavy, even if the manipulator is pulled, the machine will not move and will fall into a pressure-loss state. We all know that the problem that can not be solved by a shovel can be divided into two parts. Otherwise, it will take a lot of time and fuel to solve it.

　　三，降低发动机转速

　　Third, reduce engine speed

　　虽然降低发动机转速会影响作业量，但却可以大幅降低燃耗，提升燃耗效率。当然，前提是不会致使干活效率太低，那样的话，可能引起雇主的反感而失去到手的活儿。

　　Although reducing the engine speed will affect the amount of work, it can significantly reduce the fuel consumption and improve the fuel efficiency. Of course, the premise is that it will not lead to inefficiency, in that case, it may cause employers'disgust and lose their jobs.

　　四，减小回旋角度

　　Fourth, reduce the angle of gyration

　　挖掘机省油诀窍之减小回旋角度，减小在向自卸卡车装载时的回旋角度可以缩短作业周期，增加单位时间内的作业量，从而提升燃耗效率。这也是有效的一种省油方法，很多机手在进行装车作业，很多时候往往想不到这点，因而多花了一部分冤枉的油钱。

　　The key to saving oil for excavators is to reduce the swing angle and reduce the swing angle when loading dump trucks, which can shorten the operation cycle and increase the amount of work per unit time, thereby improving the burnup efficiency. This is also the most effective way to save fuel. Many pilots are carrying out loading operations, which are often unexpected, so they spend a part of the unjust oil money.

　　五，行走时降低发动机转速

　　Fifth, reduce engine speed while walking

　　发动机转速越快，行走时所消耗的燃料就越多。通过降低运行时的发动机转速可以提升行走时的燃耗效率。

　　The faster the engine rotates, the more fuel is consumed while walking. By reducing the engine speed during operation, the fuel consumption efficiency during walking can be improved.

　　六，实施高位挖掘

　　6. Implementing High Level Excavation

　　在挖掘现场，挖掘位置较高的部分而后再挖掘位置较低的部分的高位挖掘与低位挖掘相比，可以缩短约12% 的周期用时并可提高约8% 的燃耗效率。

　　In the excavation site, compared with the low-level excavation, the high-level excavation can shorten the cycle time by about 12% and increase the burnup efficiency by about 8%.
