Cat 365 vs Volvo EC700 in Real-World Excavation

[MikePhua]

The Rise of Heavy Excavators in the 70-Ton Class
The Caterpillar 365 and Volvo EC700 represent two titans in the 70-ton excavator category, designed for high-production earthmoving, quarry work, and large-scale demolition. Caterpillar, founded in 1925, has long dominated the global heavy equipment market with its extensive dealer network and parts support. Volvo Construction Equipment, part of the Volvo Group since 1832, has built a reputation for fuel efficiency, operator comfort, and advanced hydraulics.
Both machines are engineered for power and endurance, but their design philosophies diverge. The Cat 365 emphasizes reliability and serviceability, while the Volvo EC700 leans into performance and fuel economy. Choosing between them depends on jobsite demands, dealer support, and long-term ownership strategy.
Core Specifications and Performance Metrics
While exact specs vary by year and configuration, typical comparisons include:

• Operating weight
  Cat 365: ~70,000–75,000 kg
  Volvo EC700: ~69,000–72,000 kg
  
• Engine power
  Cat 365: ~385–404 hp
  Volvo EC700: ~470 hp
  
• Bucket capacity
  Cat 365: ~4.6 m³
  Volvo EC700: ~4.8 m³
  
• Fuel consumption
  Cat 365: ~35–40 L/hr
  Volvo EC700: ~28–34 L/hr
  
• Reach and dig depth
  Similar across both models, with slight variations based on boom/stick combinations
  

In production environments, the EC700 often outpaces the 365 in cycle times and fuel efficiency, especially in repetitive digging and loading tasks. However, the Cat 365 may offer better uptime due to simpler diagnostics and more accessible service points.
Operator Experience and Cab Design
Volvo’s EC700 cab is widely praised for its ergonomic layout, low noise levels, and visibility. Features include:

• Adjustable air-suspension seat
  
• Climate control with filtered airflow
  
• Intuitive joystick and touchscreen interface
  
• Low vibration levels due to cab isolation mounts
  

The Cat 365 cab, while more utilitarian, offers:

• Rugged controls with tactile feedback
  
• Excellent visibility over the boom and counterweight
  
• Integrated diagnostics via Cat’s Product Link system
  
• Durable interior suited for harsh environments
  

Operators often prefer the Volvo for comfort during long shifts, while fleet managers value the Cat for its simplicity and durability.
Dealer Support and Parts Availability
One of Caterpillar’s strongest advantages is its global dealer network. In North America, parts for the 365 are often available same-day or overnight. Volvo’s support varies by region; in Europe, EC700 parts are readily available, but in some parts of North America and Asia, delays can occur.
A contractor in California reported that his EC700 outperformed the Cat 365 in production but suffered from poor dealer response—even when working near a Volvo branch. In contrast, his Cat dealer provided field service within hours and stocked critical components locally.
Resale Value and Long-Term Ownership
Historically, Caterpillar machines retain higher resale value due to brand recognition and parts availability. However, Volvo’s EC700 has gained traction in Europe and parts of Asia, where fuel efficiency and emissions compliance are prioritized.
In 2024, auction data showed:

• Cat 365C with 8,000 hours: ~$180,000
  
• Volvo EC700B with 8,000 hours: ~$165,000
  

These values fluctuate based on condition, attachments, and regional demand. Machines with documented service history and OEM parts command higher prices.
Fuel Efficiency and Environmental Impact
Volvo’s D16 engine in the EC700 is designed for low fuel consumption and reduced emissions. It meets Tier 4 Final and Stage V standards, making it suitable for regulated markets. The Cat 365’s C15 engine, while powerful, consumes more fuel and may require aftermarket retrofits to meet newer standards.
A mining operation in Sweden replaced three Cat 365s with EC700s and reported a 22% reduction in fuel costs over 18 months. However, they also noted increased downtime due to electronic sensor failures in cold weather.
Maintenance and Reliability
Cat’s hydraulic system is known for its robustness and ease of repair. Volvo’s advanced hydraulics offer smoother control but require more precise calibration and specialized tools.
Recommended maintenance intervals:

• Hydraulic filter change: every 500 hours
  
• Engine oil and filter: every 250 hours
  
• Undercarriage inspection: monthly
  
• Boom/stick pin greasing: daily
  

Operators should monitor travel motor seals, swing bearing wear, and electrical connectors—especially in high-dust or wet environments.
Conclusion
Choosing between the Cat 365 and Volvo EC700 depends on priorities. If uptime, parts access, and resale value are paramount, the Cat 365 remains a solid investment. For operators seeking fuel efficiency, smoother hydraulics, and cab comfort, the Volvo EC700 delivers impressive performance. Both machines are capable of moving mountains—literally and figuratively—but the best choice hinges on dealer support, jobsite conditions, and long-term strategy. In the world of heavy excavation, the right machine is the one that keeps working when the pressure is highest.
