Compared to a standard excavator arm, an Extended Excavator Arm offers several advantages. With a ZHONGHE Excavator Long Arm, the excavator can reach deeper depths, higher heights, and longer distances, providing greater flexibility and versatility. Additionally, the excavator long reach arms allows for more precise work in tight spaces due to the smaller digging radius than the bigger excavators.
Overall, ZHONGHE Long Reach Upgrade Package enhances the excavator's capabilities and makes it more efficient and effective on a wider range of projects, including deep foundation excavation, industrial demolition, dredging at greater depths or with greater precision, large-scale digging projects, barge unloading, tank cleaning, and any job where a standard boom and stick assembly is not practical or efficient.
Using ZHONGHE Long Arm Kits with pre-installed hydraulics and hose brackets can save 24 hours of labor time that would otherwise be needed for setup by a team of three people working for eight hours a day. This allows for a quicker project start and avoids unnecessary labor costs.
Our chief engineers have experience in customizing different kinds of long stick excavator over 10 years.
We have customized more than 100 sets of heavy-duty long excavator booms for powerful excavators (crawler or floating platform), like EX2500, EX1200, EX1900, and SY980.
ZHONGHE has many patents and also received CE certification, and each unit undergoes strict cost control and quality inspection to ensure that customers receive the product they expect.
Stress and Strength Analysis
We conduct comprehensive stress and strength analysis simulations on all of our long-reach arms to ensure the highest levels of quality and durability. Our team of expert engineers utilizes cutting-edge CAD software to perform these analyses.
NDT Test
The strength and durability of ZHONGHE's Long Reach Arm is attributed to our superior quality welding. We conduct NDT testing to ensure that all welds meet or exceed our high standards. With ZHONGHE's commitment to quality, customers can trust that every Long Arm will deliver long-lasting performance. Visit excavatorboomarm.com to learn more.

FIRST--CORE CRAFT TECHNOLOGY
1. Less maintenance
Using high-quality materials, such as Q355B as default, Q690D optional, Niningbo connectors, seamless precision pipelines, graphite alloy copper sleeve, strong but light bucket cylinder.
2. Strong and sturdy
Built-in reinforcing ribs. Professional welding skills towards different bearing positions. Groove preparation(45° edge-mining) before welding.
SECOND--CORE DESIGN TECHNOLOGY
1. Tolerance within 5-10um
Hole drilling tolerance is within 5-10um, ensure accuracy.
2. Reach deeper and higher
The max work range and the max digging height are larger as the angle of the boom and arm can reach 163 degrees.
3. High work efficiency and saving fuel
Lighter while taking into account the quality, not only ensures work efficiency but also saves fuel.

Q1: Why not have boom and stick cylinders in the plan?
A1: First, the whole long arm is lengthening, but the boom just lengthening from its middle sleeve to its end, so the original boom and stick cylinder can be used. Second, using the original parts can save you costs.
Q2: How long is the boom arm can the min excavator be configured with? Whether it is necessary to increase the counterweight?
A2. Generally speaking, 30-40 excavator's longest arm suggests to be 8 meters and can configure a 0.1 cbm bucket, with no need an extra counterweight. 55 excavator's longest arm suggests to be 12 meters, and can configure a 0.1-0.15 cbm bucket, need 0.5-ton extra counterweight. 60-80 excavator longest arm suggests to be 12 meters, can configure 0.15-0.25 cbm bucket, need 0.5-0.7 ton extra counterweight.
It is not recommended to extend boom arm to the longest length as min excavator is easy to slosh.
Q3: How long will it take to install a long reach excavator boom?
It depends on the installer and machine size.
Usually disconnecting the original boom arm, sticking the cylinder, then pinching the new one is okay.
Kindly remind, preparing several containers to fill the oil before disassembling.
