Long-Reach Arm

The Monde long-reach excavator arm is the specialized attachment that extends the working reach and depth of 10–45 tonne excavators beyond the limits of the standard arm — from 15.2 metres total length and a 15-metre working reach, up to 22 metres length and a 21-metre reach in the maximum configuration.

The long-reach excavator arm provides access to areas impossible to reach with the original arm: riverbeds and channels for regularization, depths of up to 17–18 metres below the station level, tall structures for demolition at a safe distance, and areas with limited ground access where the excavator cannot be positioned at the work face.

Fabricated from Q355B steel in the standard configuration — with the option to upgrade to Q690D for applications with high mechanical stress — the long-reach excavator arm includes the bucket, the bucket cylinder, the linkages, and the hydraulic hoses in the package, facilitating direct mounting on the existing excavator without additional parts. Each configuration is customizable in length, bucket capacity, and excavation reach to match exactly the requirements of the specific project. Key advantages of the Monde long-reach excavator arm

• Working reach 15–21 metres — the Monde long-reach excavator arm extends the capacity of the standard excavator by 2–3 times compared to the original configuration. A 20-tonne excavator with a standard arm has a working reach of 7–9 metres; with the long-reach excavator arm, the same machine operates at 17–19 metres distance, reaching areas otherwise inaccessible without relocating the machine or building additional work platforms.

• 4 length configurations: 15.2m / 18m / 20m / 22m — the Monde long-reach excavator arm covers a wide range of applications, from medium-scale channel regularization with the 15.2-metre configuration to high demolition and deep dredging with the 22-metre configuration. Each configuration has its bucket dimensions and excavation reach calibrated for the weight and hydraulic force of the excavator in the 10–45 tonne class.

• Q355B steel standard, Q690D upgrade available — the structure of the long-reach excavator arm is fabricated from Q355B structural steel (yield strength 355 MPa) — the reference material for construction equipment subjected to repeated loads. For high-impact applications (crushing, breaking hard rock, demolition with heavy elements) a Q690D variant (690 MPa) is available, with double the resistance to dynamic loads.

• Complete package included — the bucket, bucket cylinder, linkages, and hydraulic hoses — the Monde long-reach excavator arm is delivered as a complete system, ready to mount. No additional components procured separately are required. Mounting on the existing excavator is carried out by the UZINEX technical team at commissioning, included in the equipment price.

• Custom length, bucket, and reach — the Monde long-reach excavator arm can be configured with intermediate lengths, different bucket capacities, and excavation reaches adapted to the exact requirements of the project. Custom configurations are sized based on the specific excavator model and the predominant type of work.

• Compatible with 10–45 tonne excavators — the long-reach excavator arm covers the medium and heavy class of excavators, from 10-tonne machines used on civil construction sites to 45-tonne excavators in quarries and major infrastructure work.

• 60-month UZINEX warranty — extended coverage for the long-reach excavator arm under continuous industrial use, with spare parts available and national technical support with a guaranteed 24–48 hour response time.

Cleaning riverbeds and regularizing irrigation channels are the applications for which the long-reach excavator arm is the industry-standard equipment. The excavator stands on the bank or the work berm, and the long-reach excavator arm reaches the center of the riverbed — distances of 12–20 metres from the standing point — without entering the water and without requiring the construction of work platforms in the bed.

The excavation depth of up to 17–18 metres below the excavator's standing level, available with the 22-metre configuration of the long-reach excavator arm, far exceeds the capacity of standard arms and allows deep dredging, excavation of deep foundations, and digging of deep shafts with a single machine, without lowering the excavator onto special platforms.

Demolition of tall structures — silos, industrial chimneys, tanks, tall reinforced-concrete structures — benefits from the long working reach of the long-reach excavator arm through the ability to operate at a safe distance from the fall zone of the demolished material. The operator and the machine stay 15–20 metres away from the demolished structure, radically reducing the risk of injury compared to demolition with a standard arm at short distances.

Work in hard-to-reach areas — on steep banks, next to existing buildings, on sites with unstable ground at the edge of the work face — is solved with the long-reach excavator arm through the ability to position the excavator on stable ground, at a safe distance, and work with the extended reach at the inaccessible work face. How to choose the correct long-reach excavator arm configuration

Selecting the correct configuration of the long-reach excavator arm depends on three main factors: the maximum distance to the work face, the required excavation depth, and the tonnage of the available excavator.

The 15.2-metre configuration is the standard choice for the regularization of irrigation channels and medium-sized watercourses, where the distance to the opposite bank or the center of the bed does not exceed 12–14 metres. The 4,800 kg weight is compatible with excavators in the 10–20 tonne class without overstressing the machine's load limit.

The 22-metre configuration of the long-reach excavator arm is the choice for work with maximum reach and depth requirements — regularization of large rivers, demolition of tall structures, and deep dredging. The 7,500 kg weight requires an excavator of at least 25–35 tonnes to maintain machine stability at maximum load. UZINEX engineers calculate the total load and verify the excavator's stability for the chosen configuration before order confirmation. Frequently asked questions about the long-reach excavator arm

Does the long-reach excavator arm require modifications to the excavator compared to the standard arm?

The Monde long-reach excavator arm mounts in place of the excavator's standard arm, using the same attachment points. No permanent modifications to the excavator structure are required. The hydraulic hoses included in the package connect to the machine's existing hydraulic circuits. The installation is reversible — the original standard arm can be remounted when needed. Is the reduction in digging force compared to the standard arm significant?

Yes — the long-reach excavator arm produces lower digging forces than the standard arm at the same hydraulic pressure, due to the longer lever arm. The digging force decreases proportionally with the increase in arm length. The long-reach excavator arm is not intended for excavating hard or compact materials at maximum distance — it is optimized for loose materials (silt, sand, earth) and for demolition where penetration force is not the critical factor. Is the excavator's stability affected by the long-reach arm?

Yes — the long-reach excavator arm shifts the load's center of gravity farther from the machine, reducing the maximum permissible load for maintaining stability. The exact calculation of the maximum load at the chosen working reach is carried out by UZINEX engineers based on the specific excavator model and the chosen arm configuration, before order confirmation. Is the long-reach excavator arm eligible for SEAP/SICAP public procurement?

Yes. UZINEX is a member of the Enterprise Europe Network and the Chamber of Commerce and Industry, delivering equipment for projects with EU funds and public procurement.
