When operating a Volvo EC700C crawler excavator, selecting the appropriate bucket size is a crucial decision that can significantly impact the machine's performance, efficiency, and the types of tasks it is best suited for. The EC700C is a versatile machine in Volvo’s line of excavators, designed for heavy-duty tasks such as large-scale digging, trenching, lifting, and material handling. To maximize the potential of this equipment, it's important to match the right bucket size with the nature of the work and the type of material being handled.
This article will explore the factors to consider when choosing a bucket size for the Volvo EC700C, the advantages of various sizes, and how the bucket selection impacts performance and efficiency in different applications.
Understanding the EC700C Excavator
The Volvo EC700C is part of Volvo's C-series range, known for its durability, productivity, and fuel efficiency. This model is equipped with a powerful engine and an advanced hydraulic system that provides the necessary lifting capacity and digging force for demanding tasks. The EC700C has an operating weight ranging from 70 to 75 tons, depending on the configuration, and is typically used in large construction projects, mining, and other heavy industries.
The performance and efficiency of the EC700C are highly influenced by the selection of attachments, including the bucket size. The right bucket ensures the excavator can move and load material effectively without overloading the machine or underperforming in terms of digging capacity.
Factors to Consider When Choosing Bucket Size
When choosing the bucket size for the Volvo EC700C, several important factors should be taken into account:
1. Type of Material
The type of material to be excavated is one of the most important factors in choosing the right bucket size. Different materials vary in density, weight, and consistency, which will affect how much material can be moved with each scoop.

• Loose or Soft Material: For digging in loose soil, sand, or gravel, a larger bucket size is ideal, as it allows the excavator to scoop more material with each pass.
  
• Hard or Rocky Material: When working with compacted soil, rock, or harder materials, a smaller, reinforced bucket might be necessary. This allows the excavator to dig more efficiently and prevent excessive wear on the bucket.
  
• Wet Materials: Wet, muddy conditions can increase the weight of the material. In such cases, a slightly larger bucket can help to compensate for the increased weight, improving the machine’s efficiency.
  

• 1.2 cubic meters (1.6 cubic yards): Ideal for general construction tasks and material handling. It strikes a balance between capacity and digging force, making it suitable for most medium-duty applications.
  
• 1.6 cubic meters (2.1 cubic yards): Commonly used for heavy-duty excavation work, this size is suitable for digging in loose to moderately compact materials such as soil, gravel, and sand.
  
• 2.0 cubic meters (2.6 cubic yards): Typically used for heavy-duty bulk material handling, this bucket size is suited for projects with large amounts of loose material like sand, gravel, or fill dirt.
  
• 1.0 cubic meters (1.3 cubic yards): Smaller buckets that are reinforced for working in tougher materials like clay, rock, or compacted soil. Ideal for digging precise trenches or in more constrained spaces.
  

• Heavy-duty buckets are designed for tough, abrasive materials and are made from higher-grade steel or alloy materials for added durability.
  
• Rock buckets are designed with reinforced edges and a more robust structure to withstand the forces of digging through rock and hard soil.
  
• Standard buckets are typically made from high-tensile steel and are suitable for general-purpose applications in softer materials.
  

The Rise of the Super Snorkel Line Loader
The Super Snorkel is a specialized line loader used in steep-slope logging operations, particularly in the Pacific Northwest and parts of British Columbia. Developed during the height of cable logging’s dominance, these machines were engineered to combine the reach of a tower yarder with the mobility of a tracked loader. Their defining feature is an extended boom—often exceeding 60 feet—mounted on a crawler base, allowing them to yard logs from deep draws and load trucks with precision.
Manufacturers like Madill, Washington Iron Works, and Cypress produced various models of Super Snorkels throughout the 1970s and 1980s. These machines were often custom-built or heavily modified in the field to suit specific terrain and timber profiles. At their peak, dozens operated across North America, especially in regions where helicopter logging was impractical and traditional tower yarders were too cumbersome.
Operating a Super Snorkel
Running a Super Snorkel requires a unique blend of finesse and spatial awareness. Unlike standard loaders, the extended boom makes the machine sensitive to road grade and balance. Operators must constantly monitor boom angle, cable tension, and machine stability—especially when working near road edges or on narrow landings.
The controls resemble those of a conventional line loader, but with added complexity due to the boom’s reach and the grapple’s swing radius. Skilled operators can yard logs from over 100 feet away, sort multiple species, and load trucks with minimal repositioning. The job demands high situational awareness and a deep understanding of terrain, timber weight, and cable dynamics.
One veteran operator described the experience as “the best job in the woods,” noting that the machine’s capabilities allowed him to work efficiently in areas where other equipment would struggle. He recalled walking his machine over 10 kilometers to reach a new site, preferring the hike over the risk of lowbed transport on narrow roads.
Decline and Displacement
Despite their effectiveness, Super Snorkels are becoming increasingly rare. The shift toward direct haul operations, narrower road construction, and smaller truck configurations has reduced the need for large-scale dryland sorts and grapple yarding. Logging companies now favor shovel logging, processor-forwarder systems, and smaller, more agile machines that can navigate tighter corridors.
The transition is driven by economic and logistical pressures. Highway trucks, which are only 8 feet wide, require narrower roads than the 11–12-foot-wide off-highway rigs used in the past. As a result, landings are smaller, and the infrastructure no longer supports the size and weight of Super Snorkels.
In some regions, companies like IPL have been sidelined by contract disputes and shifting priorities from major timber buyers. With fewer opportunities for traditional yarding, Super Snorkels sit idle, awaiting legal resolution or sale. Operators and mechanics worry that these machines will be scrapped or forgotten, despite their historical significance and remaining utility.
Preservation and Sentiment
Among logging veterans, Super Snorkels evoke deep respect. Watching a skilled operator maneuver one is considered an art form, honed over decades of experience. The machines themselves are seen as endangered species—symbols of a bygone era when cable logging ruled the forest.
Some operators have begun documenting their machines through photos and videos, hoping to preserve their legacy. Others advocate for museums or heritage fleets to keep the machines operational for demonstration and training purposes. The sentiment is clear: these machines deserve recognition before they vanish completely.
One retired logger reminisced about pushing line loaders onto lowbeds with HDX or P16 trucks, navigating hairpin corners and narrow bridges. He noted that today’s hydraulic machines wear out their undercarriages faster than the old mechanical loaders, which could last decades with proper greasing and occasional rebuilds.
Modern Alternatives and Adaptation
While Super Snorkels are fading, their influence lives on in modern forestry equipment. Track-mounted yarders, swing boom processors, and long-reach loaders borrow elements of their design. However, none match the combination of reach, power, and cable control that defined the Super Snorkel.
For operations that still require long-distance yarding, some companies retrofit excavators with extended booms and grapple systems. These hybrids offer partial solutions but lack the stability and precision of purpose-built snorkels.
To adapt, operators recommend:

• Investing in modular grapple systems for smaller machines
  
• Using drone mapping to optimize landing placement
  
• Training younger operators in cable techniques before the knowledge disappears
  
• Preserving one or two snorkels per region for specialty work and education

• Safety Risks: The constant awareness of safety protocols, combined with the potential dangers associated with machinery and construction sites, can create mental fatigue.
  
• Work-Life Imbalance: Extended hours and weekend work can cause a disconnect between personal and professional lives, leading to stress and lack of relaxation.
  

• Take Regular Breaks: Even in a high-paced environment, it’s crucial to take short breaks throughout the day to reset your mind and body. A brief walk, hydration, or stretching can help alleviate physical and mental tension.
  
• Mindfulness and Breathing Exercises: Simple mindfulness techniques, such as focusing on your breath, can help center your thoughts and reduce anxiety. Breathing exercises help calm the nervous system, lowering stress and increasing focus.
  
• Speak Up When Necessary: Don’t be afraid to ask for help or express concerns to your supervisors or coworkers. Open communication is essential in managing workload and maintaining a supportive work environment.
  

• Set Clear Goals: Each day, set realistic, achievable goals. Break down large tasks into smaller, manageable steps. This makes tasks feel more attainable and reduces the feeling of being overwhelmed.
  
• Time Management: Plan out your day in advance, allocating enough time for each task and including breaks. By managing time effectively, you’ll avoid the rush of last-minute tasks and minimize stress.
  
• Stay Organized: Keep your workspace tidy and organized. Whether it’s your vehicle, equipment, or personal items, an organized environment can help reduce mental clutter and create a more productive space.
  

• Exercise Regularly: Even if it’s just a 30-minute walk or a light workout before or after work, exercise is a great way to reduce stress and boost mood. Physical activity releases endorphins, which improve emotional well-being.
  
• Get Enough Sleep: Lack of sleep can significantly impact mental and physical performance. Ensure you’re getting enough rest each night to allow your body and mind to recharge.
  
• Healthy Diet: Eating a balanced diet rich in vitamins, proteins, and healthy fats supports both your physical energy and mental clarity. Avoid excessive caffeine and junk food, as these can lead to energy crashes and irritability.
  

• Communicate with Coworkers: Foster a positive work environment by collaborating with colleagues. Sharing experiences, venting frustrations, and offering support can help alleviate stress.
  
• Seek Professional Help if Needed: If the stress is overwhelming or persistent, it may be helpful to seek professional help from a counselor or therapist. Mental health professionals can provide techniques and strategies for managing stress, as well as offer a safe space to express emotions.
  

• Take Pride in Your Work: Recognize the value of the work you do. Whether you're operating heavy machinery or ensuring a safe work environment, the role you play is crucial to the success of the project.
  
• Celebrate Achievements: Celebrate small victories, whether it’s completing a task ahead of schedule or overcoming a challenging situation. Acknowledging progress can help you feel more accomplished and motivated.
