3.7 Excavators

Excavations are carried out using very specialized equipment which roughly falls into two categories: 1) fixed position machines, and 2) moving machines.
The choice of equipment to be used is detertmined by the size of the project, topography, volume of earth to be hauled out and many other factors. Fixed position machines include,but are not limited to, face shovels, backhoes, draglines and grabs. The “fixed” excavator loosens the soil and loads from a stationary position. They are useful to perform specific excavation tasks at a single location. Their loss of mobility is compensated by the fact that
greater force can be applied at the excavation face. “Moving” machines include, but are not limited to, bulldozers, loaders, scrapers, graders and trenching machines. They remove, transport and deposit excavated material all in one cycle of operation. They are used in applications where large volumes of earth need to be moved over uneven ground.
In this process, they also help to level the ground over which they operate. (Also see General And Civil, 11.2 of this manual.)

Answer 1

3.7挖掘机

发掘进行使用非常专业的设备大致分为两类： 1 ）固定位置机，和2 ）移动设备。

设备的选择是要使用detertmined的大小项目，地形，体积是地球拖出以及许多其他因素。固定位置的机器包括但不限于，面对铁锹， backhoes ， draglines和争夺。在“固定”挖掘机松散的土壤和负载从一个固定的位置。他们是有用的执行特定的开挖任务在一个单一地点。调动他们的损失得到补偿的是，

更大的力量可以适用于掘进工作面。 “移动”的机器包括，但不仅限于，推土机，装载机，铲运机，年级和挖沟机。他们清除，运输和存款出土材料在一个周期的运作。它们被用来在应用大容量的地球需要移动不平衡地面。

在这个过程中，返埋他们还旦祥帮助当地的漏迟蚂水平超过它们运作。 （另见秘书长和公务员， 11月2日的这本手册。
