Product Description
Engineered to maximize the operational envelope of standard earthmoving machinery, the Caterpillar Excavator Long Reach Boom and Arm (Stick) is a heavy-duty front-end attachment manufactured by Xiamen Fortune Industrial Co., Limited. Built strictly to OEM production standards using premium Q355B structural steel from first-class steel mills, this extended assembly delivers superior structural integrity and reach for demanding job sites.
Our crawler excavator long reach front attachments are available in both two-section and three-section designs to match specific machine tonnages and working conditions. The two-section configuration is widely deployed for river course silt dredging, highway embankment profiling, sand and concrete material handling, as well as deep foundation and trench excavation.
When projects demand extreme vertical depth or ultra-wide horizontal reach—such as wide-channel marine dredging or high-slope stabilization—the three-section configuration provides the necessary extension. Every assembly can be custom-fabricated according to client samples, technical drawings, and specific pin-to-pin dimensions.
Delivered as a ready-to-install kit, the package integrates 1 extended boom, 1 extended arm (stick), 1 bucket cylinder, 1 specialized bucket or grab attachment, 1 complete linkage set (H-link and I-link), 4 hydraulic hoses/steel lines, and 6 hardened mounting pins.
Application
Upgrading a standard crawler excavator with an extended boom and stick assembly significantly increases both digging radius and depth without requiring the base carrier to reposition frequently. It offers contractors a safe, high-efficiency solution when operating on soft ground, steep edges, or waterbanks where standard front equipment falls short.
Primary Job Site Uses:
- River Course & Port Dredging: Clearing underwater mud, silt, and debris across wide waterways and canals while keeping the excavator safely positioned on the bank.
-
Expressway & Slope Trimming: Grading, repairing, and stabilizing high highway slopes and steep embankments with smooth, long-pass accuracy.
- Deep Foundation & Pit Excavation: Digging deep building basements and structural pits from ground level without driving heavy equipment into the excavation zone.
-
Deep Ditch & Utility Trenching: Forming deep drainage channels, irrigation canals, and pipeline trenches in a single continuous pass.
- Sand & Concrete Material Loading: Transferring bulk aggregates, sand, and construction materials across wide obstacles or loading hoppers at extended distances.

FAQ
Q1: What steel grade and heat-treatment specs are used for your Caterpillar long reach boom and arm?
A: The main boom and arm structure is fabricated from Q355B structural steel sourced from first-class steel mills. Wear-critical components such as pins and bushings undergo heat treatment to achieve a surface hardness of HRC52–58 with a hardened depth of 8mm–12mm.
Q2: How do I choose between a two-section and a three-section long reach attachment?
A: A two-section boom and stick is ideal for general extended-reach work including river dredging, expressway slope trimming, foundation digging, and sand/concrete transfer. A three-section assembly is recommended when extra-deep excavation or specialized multi-stage reach geometry is required.
Q3: Does the attachment arrive with all necessary hydraulic piping and mounting hardware?
A: Yes. Every standard set includes 1 boom, 1 arm/stick, 1 bucket cylinder, 1 bucket or grab, 1 set of H and I linkages, 4 hydraulic hoses/steel tubes, and 6 connecting pins for direct installation.
Q4: Can you manufacture custom lengths or match non-standard excavator models?
A: Yes. Alongside standard Caterpillar models (such as E320, E320D, E330, E336, E349DL) and other major brands like Komatsu, Hitachi, Doosan, and Kobelco, we produce custom assemblies strictly according to client drawings, samples, and specific pin dimensions.
Q5: What is your warranty policy and estimated production lead time?
A: We provide a 6-month to 1-year quality guarantee on our long reach boom and arm sets. Standard production and quality inspection take 15 to 25 days after the sales contract is established, shipped in fumigated seaworthy export packaging.
