Long-Reach Excavator Advantages and Operating ...

As its name suggests, the long-reach excavator has an extended jib between the machine body and the working arm, which is powered by oil cylinder. The long arm is equipped with a set of oil cylinder operating system to provide power for the movement of the oil cylinders. All of these designs double the working range of the bucket, which can go higher, deeper and further. The great improvements make the long-arm excavator an especial digging tool for minerals, docks, storage and emergency rescue, which has great practical value.

To be specific, the long-arm digger has the following advantages:

1. Wider Applications

The long arm can work in the tough and extreme working environment where other excavators can&#;t reach. This unique advantage makes it reliable enough to handle various constructions.

2. Higher Standard

Strict technology and examination standards have been set to manufacture this machine, which guarantees its excellent construction performance.

3. Ease of Operation

The high mechanization and simple working organization of the long-reach excavator make it easier to be operated, thus improving working efficiency and saving labor resource.

4. High safety

The distance between the operator and the operating object is long, which reduces dangers in the working process. And the strengthened structure greatly improves safety.

What is more, some guidelines should be followed when operating the long-arm digger in order to make the most of its advantages.

1. The long arm should not be overloaded.

2. The piston rod of hydraulic cylinder should not move to the bottom, safe distance should be reserved.

3.  When making a rotation, the long-arm should be 0.5 meters high from the ground.

4.  The bucket load should match with the specified standard since overload will shorten the life of the long arm and the whole machine.

5.  Don't dig directly in the rocky area, crush the rocks before excavating.

6.  When the bucket is working, the excavator should not make any walking or rotation.

With a super long reach arm, stick and boom package, your excavator reach is enhanced by up to 40% than that of a standard reach configuration with approximately 40% of the digging force. This means the operator can dig with a bucket from further out with essentially less maneuvering than ever before.

Comparison Between Long Reach and Super Long Reach Excavators for Construction Sites

When selecting the right excavator for your next project, understanding the differences between long-reach and super-long-reach excavators can be crucial if you&#;re looking for more precision. Here&#;s a detailed comparison based on key parameters such as fuel efficiency, fuel usage, maximum digging depth, and hydraulic system capabilities:

Fuel Efficiency and Usage

Long Reach Excavator:

Fuel Efficiency: Long-reach excavators are generally designed to balance power, performance and efficiency. They typically feature advanced engines that optimize fuel consumption while delivering sufficient power for heavy-duty tasks. Engine oil and fuel filters are typically the main maintenance tasks. Consulting the operator&#;s manual is essential for detailed maintenance procedures and ensuring optimal performance. These excavation excavators typically boast a large fuel tank.

Fuel Usage: These excavators consume more fuel (but as above, have a larger fuel tank) than equivalent standard reach excavators due to the additional power required to operate a longer boom and arm. However, they are more cost effective than super long-reach models because they are often used for heavier duty work and excavation projects requiring more energy.

Super Long Reach Excavator:

Fuel Efficiency: Super long-reach excavators may be slightly less fuel-efficient than their long-reach counterparts. The extra length of the boom and arm increases the hydraulic workload, which can lead to higher fuel consumption and quicker replacement of engine oil and fuel filters.

Fuel Usage: Because of the potential for increased fuel consumption, manufacturers often equip these machines with features to help minimize fuel use, especially during extended periods of fine, detailed work.

Maximum Digging Depth

Long Reach Excavator:

Maximum Digging Depth: These excavators are designed to work faster in common applications that require deep digging and heavy lifting. They can essentially reach far deeper depths than standard excavation excavators but generally do not match the depth capabilities of super-long reach models. This kind of heavy equipment is perfect for construction sites that require ditch digging, demolition attachments and heavier duty work. They are cost effective and the long arm works well with other attachments, including a variety of bucket styles .

Super Long Reach Excavator:

Maximum Digging Depth: Super long-reach excavators excel at maximum reach and digging force and depth due to their extended booms. This makes them ideal for safe operation with jobs requiring work in deep or distant locations where the ability to reach farther is an absolute must.

Hydraulic System

Long Reach Excavator:

Hydraulic System: The hydraulic systems in long-reach excavators are robust and capable of handling significant stress due to the extended reach and heavier loads. This heavy equipment is engineered to offer more power to manage the increased weight of the extended boom and arm, which is essential for tasks like dredging and heavy excavation.

Super Long Reach Excavator:

Hydraulic System: In super-long-reach excavators, the hydraulic system is designed to maintain precision and control despite the longer boom and reach. These systems are fine-tuned to ensure consistent flow and pressure, which helps maintain accuracy and efficiency during operations like slope grading or digging long trenches.

Overall Considerations

Long Reach Excavators are best suited for projects that require deep digging and lifting heavy loads over extended distances. The typical long reach excavator is well-balanced in power, cost effective maintenance and fuel efficiency, and are popular as rental equipment.

Super Long Reach Excavators are perfect for project requirements that include reaching over obstacles and performing detailed, time consuming work, sometimes with other attachments, at significant distances, where depth and more precision are paramount.

Choosing between the two types of long reach excavator largely depends on the project&#;s specific needs, including the nature of the job site, the type of material to be handled, and the environmental considerations. The product specifications must be a match as well. They are not always used, making them popular rental equipment for excavation excavators.

Super Long Reach Excavators

Cat Super Long Reach Excavator is an excellent fit for lighter-duty, long-distance applications, including:

• Ditch cleaning

• Slope finishing

• Settling pond clean out

• Waterway and canal maintenance

• Vegetation control

Long Reach Excavator

Call on the HAWK Long Reach Excavation Excavator when your job calls for ditch digging and other heavier work at a distance. We also offer them as cost effective rental equipment, no matter your machine size. These long reach excavators increase productivity, power and performance in long-distance applications, including:

• General excavation

• Hydraulic dredging

• Ditch cleaning

• Settling ponds

• Canal maintenance

• Loose material transfer

With a super-long reach arm and boom package, your excavator&#;s reach is enhanced by up to 40% compared to a standard reach configuration with approximately 40% of the digging force. This means you can dig deeper and further with less maneuvering.

The super long reach kit can fit on CAT 320, 323, 326, or 330 equivalent, with the best performance coming from the CAT 323 or CAT 330. All super long reach excavators use a heavier counterweight than equivalent standard excavators, and thus have a larger operating weight.
