Three-Section Excavator Telescopic Boom Arm
An excavator with a three-section telescopic arm refers to an excavator that is equipped with an arm composed of three telescoping sections. Each section of the arm can extend or retract independently, allowing the excavator to reach a greater range and depth.
The telescopic arm design provides increased flexibility and versatility to the excavator, as it can adjust the length of the arm according to the specific requirements of the job. By extending or retracting the telescopic sections, the excavator can reach deeper into excavations or extend its reach horizontally without needing to reposition the entire machine.
The three-section telescopic arm configuration is commonly used in various construction and excavation applications. It offers advantages in tasks such as digging trenches, excavating foundations, and reaching over obstacles or structures. The telescopic arm can provide additional reach and digging depth compared to a standard excavator arm, making it useful in situations where access is limited or when working on uneven terrain.
It's worth noting that the specific capabilities and features of an excavator's telescopic arm can vary depending on the manufacturer and model. Different excavators may have different reach and lifting capacities, so it's important to consult the specifications of a particular machine to understand its capabilities fully.

II. Advantages of Excavator Telescopic Arm
Adavantage 1: The external hose pulley separates the hose from the main rope, avoids the friction between the main rope and the hose, reduces failures, and makes maintenance more convenient
Adavantage 2:Adopt 30mm main rope.Adopt 26mm auxiliary rope.
The upgraded auxiliary rope design makes the pipeline smoother while stretching
Adavantage 3: The external hose pulley separates the hose from the main rope, avoids the friction between the main rope and the hose, reduces failures, and makes maintenance more convenient.
Adavantage 4: Oil filling hole at the second arm front end (to the top slider). Oil filling hole position on both sides of the third arm front end(to the top slider)

Telescopic Boom Arm
It is nylon material , it can reduce grinding
Our sliding wheel is POM Material , with high mechanical strength and rigidity.
Two sliding wheels on the top , the others two on the bottom , this part separate the high
pressure hose and the steel rope , to reduce grinding each other ,less grinding can prolong the service life . You can see the top is for the steel rope , and the bottom is for the high pressure hose , on the both side . Besides , here also have a adjustable holder to tension hose if need.
