關于加長臂，我相信很多從事機械行業的朋友都不陌生，在市政建設、地鐵交通的完善、下水道的改建、河道清理等都須要大量的工程機械設備，而標準的挖掘機械又完成不了特殊化的工程作業，所以此時加長臂挖掘機利用超長型動臂和超長型斗桿來大展神威，可在疏浚、護岸、坡面以及地鐵建設等受地面環境限制的工況下，發揮巨大的威力。
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.
一般常見的有以下幾個應用領域：
Generally, the following application fields are common:
1.兩段式加長臂：使用范圍相對較大，但是他的主要功能也即是為了提升挖掘半徑，在清理河道，填海造地，地鐵出入口開挖，人行地底隧道，還有高速公路防護墻修整，一般住宅輸送一下水泥等等。也有人用他前置破碎錘作用于房屋拆遷的，不過比較危險。兩段式加長臂一般10-26米區間改裝比較多。
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.
2.三段式加長臂：或者多段式加長臂，主要應用于高層建筑的拆遷，前置破碎錘或者液壓鉗。20-28米內使用者比較多。
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.滑臂或者內伸縮臂：主要為了回轉半徑很小，但是挖掘深度要求很高的工況設計，一般會前置貝殼挖斗（貝形斗）?；鄞怪蓖诰蚋笊疃纫话銥?0米，內伸縮臂垂直挖掘深度一般在26米以內。
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.打樁機加長臂：大小臂平直，前置彎臂2.6米左右（主要是為了與振動錘連接是便與閥塊和管路的安裝）及震動錘，應用于修建公路鐵路或者埋設管道的時候打拔鋼板樁。
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.抓木機、抓料機裝卸煤機加長臂：更多的時候為了裝卸火車或者汽車而設計，一般大臂7.6米，小臂5-6米.前置抓木器、抓鉗器或者貝殼挖斗。
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.
挖掘機大小臂改裝前提是要考慮動力，液壓以及配重平衡幾個方面。
The precondition for refitting the boom and jib of excavator is to consider power, hydraulic pressure and counterweight balance.
