The characteristics of the extended 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。
An extended arm excavator is installed between the body bracket and the working arm. The extended arm is supported and connected by the crude oil cylinder. A working arm cylinder and the excavator bucket cylinder are installed on the extended arm. A corresponding cylinder control system is installed inside and outside the cab to coordinate the operation of the working arm cylinder and excavation. The expansion operation of bucket cylinder can expand the scope of excavation bucket more than twice and reach a higher, deeper and farther range. It is especially suitable for flood fighting and emergency operation in storage of mine wharf and special occasions. It is a breakthrough transformation of excavation machinery and has great practical value.
The structure of the excavator's elongated arm is as follows:
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。
The extended arm excavator is composed of the working arm of the extended arm crude oil cylinder, the working arm of the oil cylinder, the excavating bucket cylinder, etc. Its characteristics are as follows: an extended arm is connected with the upper end of the body bracket, the lower side of the extended arm is connected with the crude oil cylinder, the front end of the extended arm is connected with one end of the working arm through the pin shaft, and the working arm is connected with the extended arm. Install a working arm cylinder.
There is a excavator bucket at the front end of the working arm. One side of the excavator bucket is connected with one end of the excavator bucket cylinder through a connecting rod, and the other end of the excavator bucket cylinder is connected with the elongated arm through a pin shaft.
Excavator elongated arm has the following characteristics in construction:
(1) High degree of mechanization, less labor, simple construction organization, high construction efficiency and rapid progress of the project;
(2) The lengthened arm has stricter requirements on excavator quality. It can also be said that the arm is a test of excavator quality. It is not easy to segregate in the course of action, so it is easy to ensure the quality of the project.
(3) Safety of operation can reduce the danger in the construction process;
(4) It has strong adaptability to construction work and wide scope of work. The excavator's elongated arm can be laid to other difficult places to meet various construction requirements.
(5) Under normal working conditions, the longer arm of excavator will not pollute the environment and meet the requirements of environmental protection.
Classification and operating conditions of excavator elongated arm:
(1) The lengthening arm is divided into two-stage lengthening arm and three-stage lengthening arm.
（2）二段式加长臂主要适用于土砂 混凝土等建筑搬运 高速公路坡面修整及河道疏浚等；
(2) The two-stage elongated arm is mainly suitable for slope repairing and river dredging of construction and transportation Expressway such as earth sand concrete.
(3) Three-section elongated arm is mainly suitable for the disintegration of high-rise buildings.
