What are the advantages of the two-stage telescopic arm of the excavator? And what are the precautions during use?
Let me introduce it to you below！
Advantages:
1. Using BS700 or Q690D material, the overall weight is lighter and the host load is lower.
2. The external design of the arm tube is maintained in a dedicated position, enabling the replacement of the telescopic cylinder without disassembling the arm.
3. Front end design optimization, capable of carrying larger buckets and generating greater digging power.
4. The dual tube design of the internal pipeline avoids oil leakage caused by pipeline vibration, and optimizes the design to make pipeline replacement simpler and more convenient. The overall implementation allows for the replacement of all accessories without dismantling the arm.
5. With the same length of arm, our digging depth will be about 20 cm deeper than other arms.
6. The bucket cylinder is exposed outside the arm tube, which is more convenient for replacement and maintenance.
7. The hose of the bucket cylinder adopts a double-layer sleeve design to prevent pipeline vibration and easy to replace the hose.
Precautions ：
1.The operation mode of the two-stage telescopic arm of the excavator is the same as that of the standard arm. The bucket cylinder of the two-stage telescopic arm uses the pipeline of the bucket cylinder of the standard arm.
2.The telescopic arm of the two-stage telescopic arm is controlled by the breaker pipeline. The one-way foot switch needs to be replaced with a two-way foot switch before it can be used.
3.The two-stage telescopic arm is mostly used for downward excavation. It is recommended to install a camera to observe the working conditions below and expand the driver's field of vision.
4.The arm tube of the two-stage telescopic arm is relatively thin and long. Remember not to dig obliquely or pick hard objects, which may cause the arm tube to bend easily.
5.When using the two-stage telescopic arm, the movement should not be too fast, which will affect the service life of the telescopic cylinder.
6.When operating the excavator, the driver should try to avoid operating at 90° between the cab and the track plate.
7.The two-stage telescopic arm needs to be coated with butter every day, and the arm should be coated with butter at least once a week. The arm should always be filled with butter.
