Evaluating the Volvo EC700B Excavator: Strengths, Weaknesses, and User Experiences
#1
The Volvo EC700B is a large excavator designed for heavy-duty applications such as mining, quarrying, and major construction projects. Known for its advanced engineering and robust build, the EC700B represents Volvo’s commitment to combining power, efficiency, and operator comfort in the ultra-class excavator segment.
This detailed article examines whether the Volvo EC700B is “good or bad” by exploring its key features, performance attributes, common challenges, and maintenance considerations. It draws from user experiences, industry insights, and practical examples to offer a balanced assessment.
Technical Overview and Key Features
  • Operating Weight: Approximately 70 tons, making it a heavyweight in its class.
  • Engine: Typically powered by a Volvo D16 engine delivering around 544 horsepower, compliant with emission regulations.
  • Hydraulic System: Advanced electro-hydraulic system with load-sensing technology for precise and efficient operation.
  • Bucket Capacity: Usually ranges from 3.0 to 5.0 cubic meters, adaptable to different tasks.
  • Fuel Efficiency: Designed to reduce fuel consumption through optimized hydraulics and engine management.
  • Operator Comfort: Spacious cab with ergonomic controls, low noise levels, climate control, and advanced monitoring systems.
  • Durability: Heavy-duty undercarriage, reinforced boom and stick, and wear-resistant components suited for tough environments.
Performance Strengths
Users praise the Volvo EC700B for:
  • Power and Productivity: High engine output combined with efficient hydraulics allows fast cycle times and effective material handling.
  • Fuel Economy: Thanks to its load-sensing hydraulics and smart engine control, the EC700B often delivers better fuel consumption compared to competitors in similar size classes.
  • Operator Comfort and Safety: The cab design reduces fatigue with excellent visibility and user-friendly controls, increasing operational safety.
  • Serviceability: Components are arranged to allow easier access during routine maintenance, shortening service times.
Common Challenges and Weaknesses
While generally well-regarded, the EC700B has faced some criticisms:
  • Initial Cost and Parts Availability: The high upfront investment and sometimes limited availability of genuine Volvo parts can be challenging, especially in remote regions.
  • Complex Electronics: The advanced monitoring and control systems, while beneficial, can be difficult to troubleshoot without proper diagnostic tools and trained technicians.
  • Undercarriage Wear: Some users report faster than expected wear on undercarriage components when operating in abrasive environments.
  • Hydraulic Hose Failures: In certain cases, hydraulic hoses have shown susceptibility to premature wear or damage from debris.
Maintenance Considerations
Maintaining the EC700B requires adherence to manufacturer-recommended schedules:
  • Hydraulic Fluid and Filters: Regular changes and inspection prevent contamination-related issues.
  • Engine Servicing: Includes oil changes, filter replacement, and diagnostics to ensure optimal performance.
  • Undercarriage Inspection: Monitoring track wear and adjusting tension prevent costly repairs.
  • Software Updates: Updating control software ensures efficient machine operation and access to new features.
Small Story: Fuel Savings in a Quarry Operation
A large quarry operation switched from an older competitor excavator to the Volvo EC700B and reported a 15% reduction in fuel costs over six months. The improved hydraulic efficiency and load-sensing technology allowed the machine to adapt power usage dynamically, significantly cutting fuel consumption during idle and light-load periods. This case highlighted the long-term savings potential despite the EC700B’s higher acquisition cost.
Glossary of Terms
  • Load-Sensing Hydraulics: A system that adjusts hydraulic pump output based on actual demand, reducing energy waste.
  • Cycle Time: The time it takes to complete one full excavation cycle (dig, swing, dump, return).
  • Undercarriage: The lower frame of the excavator including tracks, rollers, and sprockets.
  • Electro-Hydraulic System: A system where electronic controls manage hydraulic components for precise operation.
  • Diagnostic Tools: Software and hardware used to read machine data and troubleshoot faults.
Industry Context and Comparisons
The Volvo EC700B competes with other ultra-class excavators like the CAT 6060 and Komatsu PC8000. While it often excels in fuel efficiency and operator comfort, some users prefer competitors for parts availability or dealer support depending on region.
Volvo's emphasis on innovation and environmental compliance aligns with modern construction demands. This focus has increased acceptance of the EC700B among contractors prioritizing sustainability and total cost of ownership.
User Insights and Feedback
Operators frequently commend the EC700B’s smooth hydraulic response and ease of control, noting reduced operator fatigue during long shifts. However, some emphasize the importance of training to maximize benefits from its electronic systems.
Certain fleet managers recommend stocking critical spare parts locally and developing technician expertise in Volvo diagnostics to mitigate downtime risks.
Summary
The Volvo EC700B excavator is a powerful, fuel-efficient, and operator-friendly machine suited for demanding excavation and material handling tasks. Its advanced hydraulic system and robust design contribute to high productivity and comfort.
Challenges primarily relate to the complexity of electronics, maintenance demands, and parts logistics, especially in less-served markets. Nonetheless, for contractors focused on efficiency, sustainability, and operator well-being, the EC700B often proves a worthwhile investment.
Understanding its strengths and potential weaknesses, combined with diligent maintenance and skilled operation, enables users to fully leverage the EC700B’s capabilities and achieve excellent performance in heavy-duty applications.
