Three-section excavator telescopic arm

key working conditions for an excavator equipped with a telescopic boom arm:

1. Terrain and Ground Conditions:

Often required to operate on uneven, soft, or unstable ground such as construction sites, demolition areas, or rough terrain
May need to navigate through tight spaces, slopes, or areas with obstacles overhead

2. Load Handling

Tasked with lifting, positioning, and maneuvering heavy loads at significant reach distances from the machine
Extended boom places additional stresses on the excavator's structure, hydraulics, and stability when handling heavy loads

3. Operator Skill and Vigilance

Demands a high degree of operator skill to precisely control the boom extension/retraction and attachment positioning
Operators must be attentive to avoid contact hazards, tip-over risks, and maintain job site safety
Proper training is crucial for safe and effective use of the telescopic boom

4. Environmental Factors

Weather conditions like wind, rain, or extreme temperatures can impact operation
Dust, debris, and limited visibility from the work site can further challenge the operator

Advantages of excavator telescopic arm

key advantages of an excavator with a telescopic boom:

Increased Reach and Lifting Capacity: The telescopic boom allows the excavator to extend the working range and reach materials or loads that would otherwise be inaccessible to a standard fixed boom. This expanded reach can be useful for tasks like loading trucks, demolishing tall structures, or working in confined spaces.

Versatility: The telescopic functionality gives the excavator more flexibility in positioning the attachment (e.g. bucket, hammer, grapple) precisely where needed. This makes the excavator more versatile and able to handle a wider range of applications.

Compact Transport Size: When retracted, the telescopic boom allows the excavator to have a more compact profile for easier transport between job sites on a trailer.

Reduced Strain on Hydraulics: The telescopic mechanism distributes the lifting forces across multiple hydraulic cylinders, reducing the strain on any single component compared to a fixed boom design.

Improved Stability: The extended reach of the telescopic boom can often provide a more stable working platform, especially for heavy lift tasks, compared to a standard fixed boom.

Enhanced Visibility: The operator may have better visibility of the work area when the boom is extended, allowing for more precise control and positioning of the attachment.

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.
