Three-section excavator telescopic arm

A three-section telescopic boom excavator refers to an excavator equipped with an arm composed of three telescopic sections. Each section of the arm can be extended or retracted independently, allowing the excavator to reach greater reach and depth.

The telescopic boom design provides the excavator with greater flexibility and versatility as it can adjust the length of the boom to the specific requirements of the job. By extending or retracting the telescoping section, the excavator can dig deeper or extend its reach horizontally without having to reposition the entire machine.

Three-section telescopic boom configurations are commonly used in a variety of construction and excavation applications. It offers advantages in tasks such as digging trenches, digging foundations, and climbing over obstacles or buildings. Telescopic arms provide additional reach and digging depth compared to standard excavator arms, making them useful when access is limited or when working on uneven terrain.

It’s worth noting that the specific functions and features of an excavator telescopic boom may vary by manufacturer and model. Different excavators may have different working ranges and lifting capabilities, so be sure to check the specifications of your specific machine to fully understand its capabilities.

Advantages of excavator telescopic arm

Advantage 1: The external hose pulley separates the hose from the main rope, avoiding friction between the main rope and the hose, reducing failures and making maintenance more convenient.

Advantage 2: Using 30mm main rope. Use 26mm auxiliary rope.

Upgraded auxiliary rope design to make pipe stretching smoother

Advantage 3: The external hose pulley separates the hose from the main rope, avoiding friction between the main rope and the hose, reducing failures and making maintenance more convenient.

Advantage 4: The oil filling hole is at the front end of the second arm (to the upper slider).
The refueling holes are located on both sides of the front end of the third arm (to the top slider)

Three-section telescopic arm
The main material we choose is Q690/HG785
lighter and stronger

The main material of the arm tube we use is Q690D/HG785
Extended life, lighter, stronger
Another place we use Q355B.

Nylon material to reduce wear
Our pulleys are made of POM material, which has high mechanical strength and rigidity.
Two sliding wheels are at the top and two others at the bottom, this part separates the high and low parts.
The pressure hose and steel wire rope reduce mutual friction. Less friction can extend the service life. You can see the top is the wire rope and the bottom is the high pressure hose on either side. Additionally, there is an adjustable bracket here to tighten the hose as needed.

The first system is the technical design drawing review mechanism,

The second system is the semi-finished product review mechanism,

(each process has a detection testing for the previous process)

The third system is the finished product testing.

(Before painting, the overall inspection is carried out to check whether the design size matches the welding size, and whether the installation size meets the design requirement.)

To sum up, every single ZHONGHE product has been passed the above three-stage inspection system to ensure that is qualified before shipping.
