Lengthened arm excavator leasing teaches you to identify excavator classification:

　　根据其不同的机械作用原理，分为铲、铲、抓、拉铲。

　　According to its different mechanical principle, it can be divided into shovel, shovel, grab and pull shovel.

　　根据其不同的结构和材料性能:分为标准斗、加强斗、岩石斗

　　According to its different structure and material properties, it can be divided into standard bucket, reinforced bucket and rock bucket.

　　根据不同的工作条件和功能:可分为土方斗、岩斗、松散土斗、沟斗、格栅斗、抓斗、清斗、倾斜斗等。

　　According to different working conditions and functions, it can be divided into earthwork bucket, rock bucket, loose soil bucket, ditch bucket, grille bucket, grab bucket, clear bucket, tilt bucket, etc.

　　根据其不同的机械作用，分为铲、铲、抓、拉铲。

　　According to its different mechanical functions, it can be divided into shovel, shovel, grab and pull shovel.

　　挖掘机安装在斗杆的末端，由油缸驱动。掘进过程中，掘进力是向上和向下的，掘进轨迹通常为弧形。适用于停采面以上的砂石及煤矿的开挖。

　　The excavator is installed at the end of the bucket rod and driven by the cylinder. In the process of excavation, the driving force is upward and downward, and the trajectory of excavation is usually curved. It is suitable for the excavation of sand and gravel above stopping face and coal mine.

　　挖掘机反铲:采用斗杆连杆铰接，油缸驱动。工作时，开挖力由上而下，开挖轨迹为圆弧。

　　Excavator backhoe: bucket rod connecting rod hinged, cylinder driven. When working, the excavation force is from top to bottom, and the excavation track is circular arc.

　　挖掘机的抓斗为壳体状，由液压缸驱动抓斗抓取物料，或根据物料的重量将绳索垂直提起切割物料。它一般用于建筑基坑开挖、深基坑开挖和煤、砂、镍、砾石等松散材料的装填，特别适用于开挖或装填一侧沟道或限制空间。

　　The grab of excavator is shell-shaped. The grab is driven by hydraulic cylinder to grab material, or the rope is lifted vertically to cut material according to the weight of the material. It is generally used for excavation of building foundation pit, excavation of deep foundation pit and filling of loose materials such as coal, sand, nickel, gravel, etc. It is especially suitable for excavation or filling of one side channel or limited space.

　　铲子为盘形，有齿块和斗齿。在施工过程中，铲斗被抛在开挖面上。铲齿以自身的重量切入土层，然后用缆绳拉动铲斗进行挖掘。铲斗挖好后，由吊索吊起铲斗，翻斗通过转向平台卸土。机器表面下可以挖土，但挖的精度较差。

　　The shovel is disc-shaped with teeth and bucket teeth. During the construction, the bucket is thrown on the excavation surface. The shovel teeth cut into the soil with their own weight, and then drew the shovel bucket with a cable to dig. After the bucket is excavated, the bucket is lifted by the sling and unloaded by the turning platform. Underneath the surface of the machine, soil can be excavated, but the accuracy of excavation is poor.

　　挖掘机铲斗按结构和材料性能分为:标准铲斗、钢筋铲斗、岩石铲斗。

　　Excavator buckets are divided into standard buckets, reinforced buckets and rock buckets according to their structure and material properties.

　　标准挖掘机选用国产高强结构钢Q345B，标准特点:斗口面积大，具有较大的桩面，因此具有较高的填充系数;节省时间，效率高。适用于一般粘土的开挖、砂土、砂砾石的加载等轻作业环境。

　　Standard excavator adopts Q345B high-strength structural steel made in China. Standard features: large bucket area, large pile surface, so it has high filling coefficient, saving time and high efficiency. It is suitable for light working environment such as excavation of common clay, loading of sand and gravel, etc.

　　在标准铲斗的基础上，采用高强度耐磨钢材料在高应力、易损件处进行加固。易损件齿座板、侧缘板均采用国产高强度耐磨钢NM360制造，加厚板，延长使用寿命。它继承了标准斗的所有优点，大大提高了斗的强度和耐磨性。适合于挖硬土、砾石、砾石装载等重载作业的环境。

　　On the basis of standard bucket, high strength wear-resistant steel material is used to reinforce high stress and vulnerable parts. The tooth base plate and side edge plate of vulnerable parts are made of high-quality and high-strength wear-resistant steel NM360 made in China. The plate is thicker and the service life is prolonged. It inherits all the advantages of the standard bucket and greatly improves the strength and wear resistance of the bucket. Suitable for hard soil excavation, gravel, gravel loading and other heavy-duty operation environment.

　　在岩石状桶的底部加有加强板。增加侧护板;安装防护板，在桶底采用双圆弧设计，增加鞋跟部分的接地间隙，减少磨损;与斗杆连接处采用间隙调节套筒装置。选用瑞典HARDOX超高强度耐磨钢，使产品寿命延长数倍;斗齿具有特殊的岩石斗齿。使产品可靠性高，采掘性能好，经济效益更加突出。适宜环境:开挖坚硬岩石，次生坚硬岩石与风化石混合在土壤中;爆破后硬岩和矿石的装载。

　　A reinforcing plate is added to the bottom of the rock barrel. Adding side guard plate, installing guard plate, adopting double arc design at bottom of barrel, increasing grounding clearance of heel part, reducing wear and tear, and adopting gap adjustment sleeve device at connection with bucket rod. Swedish HARDOX ultra-high strength wear-resistant steel is selected to prolong the life of the product several times, and the bucket teeth have special rock bucket teeth. So that the product has high reliability, good excavation performance, and more prominent economic benefits. Suitable environment: excavating hard rock, mixing secondary hard rock with weathered fossils in soil; loading of hard rock and ore after blasting.
