中挖掘机加长臂发展分析。我国挖掘机的发展起步于20世纪70年代后期，国内生产挖掘机加长臂的厂家从无到有，先后全国兴起了100多家大大小小的挖掘机加长臂生产厂家，产量每年以上百套的速度推向市场。虽然市场发展形势良好，但由于政府对挖掘机加长臂非标件的生产监管制度还不完善，部份制造商仿制拼装、粗制滥造，所以造成了挖掘机加长臂市场鱼龙混杂的局面。本文笔者根据多年的从业经验就如何甑别挖掘机加长臂的优劣，从哪些方面考察才能选购到质优价廉、服务卓越的挖掘机加长臂，提出几点建议，供大家探讨。加长臂挖掘机租赁
The development of China's Excavator started in twentieth Century 70 in the late 1990s, the domestic production plus the long arm of excavator manufacturers from scratch, has the rise of more than 100 large and small, plus the long arm excavator manufacturers, production each year more than 100 sets of speed to market. Although the market situation is good, but because the government plus the long arm of excavator non-standard parts production supervision system is not perfect, some manufacturers of generic assembly, shoddy, so the long arm excavator market cohabitation situation. In this paper, the author based on years of experience on how to distinguishing the excavator plus the long arm of the pros and cons, from which aspects to purchase high quality and low price, excellent service with long arm excavator, several suggestions are put forward for discussion.
1、挖掘机加长臂的特点：
The characteristics of 1, plus the long arm of excavator:
加长臂挖掘机，它是在车体支架及工作臂之间，加装一个加长臂，加长臂由原油缸支撑连接，并在加长臂上加装了一个工作臂油缸及挖掘斗油缸，在驾驶室内外，相应的加装了一套油缸的操纵系统，配合操纵工作臂油缸及挖掘斗油缸的伸缩作业，可使挖掘斗的活动范围扩大一倍以上，达到的范围更高、更深、更远，特别适应矿山、码头、仓储、抗洪抢险及特殊的场合作业，是挖掘机械的一大突破性改造，具有极大的实用价值。
Plus the long arm of excavator, which is between the body frame and the working arm, with a long arm, plus the long arm is connected by the original cylinder support, and in the long arm is equipped with a working arm oil cylinder and the bucket cylinder, and in the cab, the installation of the operating system of a cylinder, with expansion operating arm oil cylinder and the bucket cylinder, can make the bucket to expand the scope of activities more than doubled, to achieve higher, deeper, farther, especially suitable for mines, docks, storage, flood and special occasions, is a major breakthrough in the transformation of mining machinery, has great practical value.
2、挖掘机加长臂的组成结构：
Composition of 2, plus the long arm of excavator:
加长臂挖掘机，由工作臂、加长臂、原油缸、工作臂油缸、挖掘斗油缸等组成，其特征是：在车体支架上端配合连接一个加长臂，加长臂的下侧面与原油缸相连接，加长臂前端通过销轴与工作臂的一端配合连接，工作臂与加长臂之间安装一个工作臂油缸。在工作臂的前端有一个挖掘斗，挖掘斗一侧通过连杆与挖掘斗油缸的一端连接，挖掘斗油缸的另一端通过销轴与加长臂配合连接。加长臂挖掘机租赁：***
Plus the long arm of excavator, the working arm, arm, arm cylinder, cylinder, bucket cylinder etc, which is connected with a long upper part of the body frame, the lower side of the oil cylinder and the long arm is connected with the front end of the pin shaft end, plus the long arm and arm connected with the a working arm oil cylinder is arranged between the arm and the long arm. In front of the working arm of a bucket, bucket by a connecting rod and one end side of mining excavator bucket cylinder connected to the other end, digging bucket cylinder are connected through a pin shaft and a long arm with.
