As for the elongated arm excavator, I believe that many friends in the mechanical industry are familiar with it. Municipal construction, improvement of subway traffic, sewage reconstruction, river cleaning and so on require a large number of construction machinery and equipment, and the standard work of mining machinery engineering should not be completed. Therefore, the elongated arm excavator uses super-long arm and super-long arm. It shows that they can play an important role in dredging, revetment and slope, while subway construction is restricted by the ground environment conditions.
Common applications include:
1. Two-stage elongated arm
Its main function is only to increase the excavation radius. It is mainly used for cleaning rivers, reclamation, subway entrance excavation, pedestrian tunnels, highway wall repair, ordinary residential transport cement and so on. Others smashed the house with his hammer, but it was more dangerous. Generally speaking, the two-stage telescopic boom has more changes in the range of 10-26 meters.
2. Three-stage elongated arm
It is mainly used for demolition of high-rise buildings, breakage of front hammer or hydraulic clamp. More users within 20-28 meters.
3. Sliding arm or telescopic arm:
The prefabricated cylinder is usually used for the design of working conditions with small rotating radius but very high requirement for excavation depth. The maximum vertical excavation depth of the sliding arm is generally 10 meters, and the vertical excavation depth of the telescopic arm is generally less than 26 meters.
4. Pile driver lengthening arm:
The large forearm is straight, and the forearm is about 2.6m (mainly used for connecting with the vibration hammer to facilitate the installation of valve blocks and pipes). The vibration hammer is used to pull steel sheet piles when constructing highways, railways or buried pipes.
5. Extended arms of coal conveyor and wood grabber:
In most cases, it is designed for loading and unloading trains or cars, usually with 7.6 meters of arms and 5-6 meters of arms.
The premise of large forearm retrofit of excavator is to consider many factors such as power, hydraulic pressure and balance.
The length of telescopic arm of excavator is directly related to the quality and output pressure of excavator. When choosing the telescopic arm of excavator, the length of telescopic arm of excavator should be determined according to the working environment, working requirements, the quality of excavator bucket and the capacity of excavator bucket. The telescopic arm of two-stage excavator usually includes three main parameters: excavation height, excavation depth and working radius. The telescopic arm of three-level building demolition machine usually involves three main parameters: lifting height, safe working height and working radius. Only comprehensive factors can determine how long the machine can be equipped with the extended arm of the excavator.
The long arm of excavator commonly used in industry is the large forearm which is also lengthened at the same time. Such as 15.4 meters, 16 meters, 18 meters, 20 meters, 22 meters, 24 meters, 25 meters, 26 meters and so on. In fact, in 10-30 meters or longer, you can choose to extend the arm length modification. The table below is for your reference, and it is also selected according to your construction situation.
In the increasingly fierce market environment, the rational and effective use of resources is very important. Of course, the practical problems of choosing more flexible and excavators have become entrepreneurs. For example, the practicability and flexibility of long-term prosperous excavators is very effective for a member's website, but it can make you realize that "driver, all I have!" want to go.
