- The excavator telescopic boom is a special working device mounted on the excavator boom to flexibly expand its working radius and vertical deep excavation range.
- According to its structure and appearance, it can be divided into: external expansion and internal expansion; [1]
- The outer telescopic arm is mainly characterized by: 1. The outer telescopic arm is composed of an upper sliding arm and a lower fixed arm. The upper sliding arm is installed above the lower fixed arm, and the movable body is formed by the rollers on both sides and the rails. To expand and retract freely. 2. The upper sliding arm is equipped with a telescopic cylinder. The cylinder of the telescopic cylinder is fixed on the lower fixed arm, and the piston rod of the telescopic cylinder is fixed on the upper sliding arm. Its main components are: fixed body, moving body, slider, telescopic cylinder, etc. The outer telescopic arm has a large force and a simple structure, and can freely adjust the working radius and the excavation depth. It is easy to operate and is suitable for specific environment operations. But its travel is small, and its travel is generally within 4 meters.
- The inner telescopic arm is mainly characterized by: 1. The inner telescopic arm is sleeved by the moving body into the fixed body, and the mobile body is extended and retracted through the expansion and contraction of the telescopic cylinder to achieve the purpose of free telescopic; 2. There is only one structure The fixed body and one or more moving bodies. The first section is a fixed body, and the rest are moving bodies. The moving body is inserted into the fixed body in order according to its size. The principle is to insert two sections into one section and three sections into two sections ... The telescopic cylinder is used to extend or retract in sequence. The inner telescopic arm has a more complex structure and higher production cost. It is generally designed into two or more sections for grasping and raising soil in deep pit operations. The advantage is increased working radius and digging depth.
- Application fields of excavator telescopic booms: They are all used in special operating environments that are limited by the working radius and the depth of the digging range. They can flexibly increase or decrease their working radius and digging depth range, effectively improving work efficiency. [1]
