How to Choose an Excavator Long Arm?

May 15 , 2023

An excavator long arm, also known as a long reach attachment, is a specialized tool that extends the reach and digging capabilities of an excavator. It is commonly used in construction, demolition, and other applications that require increased digging depth or extended reach. If you're considering purchasing an excavator long arm, this guide will provide you with essential information to help you make an informed decision. Read on to learn about the key factors to consider when choosing an excavator long arm.


Understand Your Needs:

Before buying an excavator long arm, it's crucial to assess your specific requirements. Consider the tasks you need to accomplish and the conditions in which you will be operating. Determine the required digging depth, reach, and the types of materials you will be handling. Understanding your needs will help you choose an excavator long arm that is best suited for your specific applications.



Ensure that the long arm you choose is compatible with your existing excavator. Consider factors such as the excavator's make and model, hydraulic flow and pressure requirements, and weight limitations. Consult the excavator manufacturer's specifications or seek advice from a reputable dealer or manufacturer to ensure a proper fit.

Digging Depth and Reach:

Digging depth and reach are critical considerations when choosing an excavator long arm. Determine the depth at which you need to dig and the maximum horizontal reach required for your tasks. Long arms are available in various lengths, typically ranging from 12 to 25 meters (40 to 82 feet). Select a length that meets your specific project requirements, balancing reach and stability.


Bucket Capacity and Type:

Consider the bucket capacity and type that are compatible with the long arm. Bucket capacity determines the amount of material the excavator can move in one cycle. Evaluate the types of materials you will be handling and the required bucket capacity for efficient operation. Additionally, consider the bucket type, such as general-purpose, heavy-duty, or specialized buckets, depending on the nature of your tasks.


Hydraulic Performance:

Evaluate the hydraulic performance of the excavator long arm. Adequate hydraulic power is essential for smooth and efficient operation. Consider the hydraulic flow and pressure requirements of the long arm and ensure that your excavator can provide sufficient hydraulic power. Inadequate hydraulic performance can lead to decreased productivity and potential damage to the long arm or excavator.

Durability and Construction:

Choose an excavator long arm that is built to withstand the demands of your applications. Look for robust construction and high-quality materials that ensure durability and longevity. Pay attention to features such as reinforced boom and arm sections, durable joints and pins, and protective coatings or treatments that enhance resistance to wear, corrosion, and impacts.


Ease of Installation and Maintenance:

Consider the ease of installation and maintenance when selecting an excavator long arm. Opt for a long arm that can be easily installed and detached, allowing for quick and efficient setup on-site. Additionally, choose a long arm that facilitates convenient maintenance access to key components, such as hydraulic hoses, cylinders, and fittings. Ease of installation and maintenance will contribute to overall productivity and cost-effectiveness.


Safety Features:

Prioritize safety when choosing an excavator long arm. Look for safety features such as overload protection systems, anti-drop valves, and reinforced structures that enhance operator and job site safety. Safety should always be a top priority to minimize the risk of accidents or equipment damage.


Budget Considerations:

Set a budget for your excavator long arm purchase and consider the cost-effectiveness of the options available. Compare prices from different manufacturers or dealers, but also consider the quality, durability, and performance of the long arm. Remember that investing in a high-quality long arm may offer better long-term value.
