关于加长臂，我相信很多从事机械行业的朋友都不陌生，在市政建设、地铁交通的完善、下水道的改建、河道清理等都须要大量的工程机械设备，而标准的挖掘机械又完成不了特殊化的工程作业，所以此时华体会国际 利用超长型动臂和超长型斗杆来大展神威，可在疏浚、护岸、坡面以及地铁建设等受地面环境限制的工况下，发挥巨大的威力。
As for the extended boom, I believe that many friends in the machinery industry are familiar with it. A large number of engineering machinery and equipment are required in municipal construction, subway traffic improvement, sewer reconstruction, river cleaning, etc., and standard excavation machinery can not complete special engineering operations. Therefore, the extended boom excavator uses the super long boom and super long bucket to show its power in dredging, bank protection The slope and subway construction will exert great power under the working conditions limited by the ground environment.
一般常见的有以下几个应用领域：
Generally, the following application fields are common:
1.两段式加长臂：使用范围相对较大，但是他的主要功能也即是为了提升挖掘半径，在清理河道，填海造地，地铁出入口开挖，人行地底隧道，还有高速公路防护墙修整，一般住宅输送一下水泥等等。也有人用他前置破碎锤作用于房屋拆迁的，不过比较危险。两段式加长臂一般10-26米区间改装比较多。
1. Two segment extension arm: relatively large scope of use, but its main function is to improve the excavation radius, such as river cleaning, land reclamation, subway entrance and exit excavation, pedestrian tunnel, highway protective wall repair, and general residential transportation of cement. Some people also use the front breaking hammer to act on house demolition, but it is dangerous. The two-stage extension boom is usually refitted in the 10-26m section.
2.三段式加长臂：或者多段式加长臂，主要应用于高层建筑的拆迁，前置破碎锤或者液压钳。20-28米内使用者比较多。
2. Three segment extension arm: or multi segment extension arm, mainly used for demolition of high-rise buildings, front crushing hammer or hydraulic tongs. There are many users within 20-28 meters.
3.滑臂或者内伸缩臂：主要为了回转半径很小，但是挖掘深度要求很高的工况设计，一般会前置贝壳挖斗（贝形斗）。滑臂垂直挖掘更大深度一般为10米，内伸缩臂垂直挖掘深度一般在26米以内。
3. Sliding arm or inner telescopic arm: mainly designed for working conditions with small turning radius but high requirements for excavation depth, usually the shell bucket (shell bucket) is placed in front. The greater depth of the sliding arm vertical excavation is generally 10m, and the vertical excavation depth of the inner telescopic arm is generally within 26m.
4.打桩机加长臂：大小臂平直，前置弯臂2.6米左右（主要是为了与振动锤连接是便与阀块和管路的安装）及震动锤，应用于修建公路铁路或者埋设管道的时候打拔钢板桩。
4. Extended arm of pile driver: the big and small arms are straight, the front bent arm is about 2.6m (mainly for connecting with the vibratory hammer to facilitate the installation of valve block and pipeline) and the vibratory hammer are used to drive and pull steel sheet piles when building roads and railways or burying pipelines.
5.抓木机、抓料机装卸煤机加长臂：更多的时候为了装卸火车或者汽车而设计，一般大臂7.6米，小臂5-6米.前置抓木器、抓钳器或者贝壳挖斗。
5. Wood grabbing machine, coal loader and coal loader extension arm: more often, it is designed for loading and unloading trains or cars, with a general boom of 7.6 meters and a small boom of 5-6 meters. The front wood grabber, gripper or shell bucket.
挖掘机大小臂改装前提是要考虑动力，液压以及配重平衡几个方面。
The precondition for refitting the boom and jib of excavator is to consider power, hydraulic pressure and counterweight balance.
