Is the Mecalac 6MCR Worth the Investment

[MikePhua]

Origins and Design Philosophy of the Mecalac 6MCR
The Mecalac 6MCR is a hybrid machine that merges the capabilities of a compact excavator with the speed and versatility of a skid steer. Developed by Mecalac Group, a French manufacturer known for its unconventional engineering, the 6MCR was designed to challenge traditional equipment categories. Mecalac began in the 1970s and expanded rapidly across Europe before entering North American markets in the 2010s. Their machines are built around the principle of multifunctionality—reducing the number of machines needed on a jobsite by combining roles.
The 6MCR is part of the MCR series, which includes models ranging from 6 to 10 tons. It features a unique boom design that allows for both excavator-style digging and loader-style pushing. With a top travel speed of 10 km/h (6.2 mph), it outpaces most compact excavators, making it ideal for jobs that require frequent repositioning.
Key Specifications and Capabilities

• Operating weight: ~5,700 kg (12,566 lbs)
  
• Engine: 75 hp diesel, typically a Deutz or Perkins variant
  
• Hydraulic flow: Up to 85 L/min (22.5 gpm)
  
• Bucket breakout force: ~3,600 kgf (7,937 lbf)
  
• Travel speed: Up to 10 km/h (6.2 mph)
  
• Boom type: Mecalac patented variable geometry boom with integrated offset
  

The standout feature is its ability to switch between excavation and loading modes seamlessly. The boom pivots laterally, eliminating the need for a traditional offset boom and allowing for precise trenching along walls or curbs. The machine also supports a wide range of attachments, including trenching buckets, pallet forks, and grading blades.
Field Performance and Operator Impressions
Operators who have tested or owned the 6MCR report mixed but generally positive impressions. One contractor who specializes in fiber conduit installation noted that the machine’s speed and multifunctionality allowed him to complete an extra run of 2-inch conduit per day—translating into significant revenue gains. He had previously used a Takeuchi TB260 and found the Mecalac’s travel speed and hydraulic responsiveness superior for his specific workflow, which involves long tracking distances and frequent repositioning.
However, concerns were raised about the complexity of the machine. With numerous grease points, hydraulic hoses, and electronic systems, the 6MCR demands diligent maintenance. Some operators expressed hesitation about long-term ownership, preferring to rotate the machine out before major repairs become necessary.
Terminology and Mechanical Notes

• Variable Geometry Boom: A boom that changes shape and position dynamically, allowing for both vertical digging and horizontal pushing.
  
• Auxiliary Hydraulic Flow: The flow rate available for powering attachments; higher flow enables more demanding tools like trenchers or mulchers.
  
• Grease Zerks: Lubrication fittings located at pivot points; high counts indicate more wear-prone joints.
  
• Side Loading Stops: Reinforcement features on the bucket that prevent lateral stress from damaging the stick during loader-style pushing.
  

One operator noticed reinforced stops on the back of the bucket, designed to press against the blade when pushing material. This design mimics skid steer behavior and reduces twisting forces on the dipper arm.
Comparative Analysis and Alternatives
Some contractors questioned whether the 6MCR was an overengineered solution to a simple problem. Alternatives like pairing a compact track loader (CTL) with a conventional excavator offer similar versatility with potentially lower complexity. However, for operations where space, crew size, and transport logistics are constrained, the 6MCR’s all-in-one nature becomes a strategic advantage.
For example, a contractor running minimal crew on a rural fiber installation project found that the 6MCR reduced the need for multiple machines and operators. With over 300,000 feet of conduit tracked in a year, the machine’s speed and agility directly impacted productivity.
Maintenance and Ownership Considerations
Before committing to a Mecalac 6MCR, prospective buyers should consider:

• Availability of local dealer support and parts
  
• Familiarity with European-style controls and boom geometry
  
• Willingness to perform regular lubrication and hose inspections
  
• Resale value and market interest in used units
  

One dealer reported that a nearby 6MCR had logged over 4,000 hours and remained in good condition, suggesting that with proper care, the machine holds up well. Mecalac’s growing presence in North America also means more dealers are stocking parts and offering service.
Recommendations for Deployment
For contractors considering the 6MCR, the following strategies can maximize its value:

• Use high-flow attachments to leverage the hydraulic capacity
  
• Schedule regular maintenance intervals, especially for pivot points and hose routing
  
• Train operators on the unique boom geometry to avoid misuse
  
• Pair with a second 6-ton unit for tandem operations on long conduit runs
  

In one case, a contractor considered deploying two 6MCRs—one at the front of the plow train and one at the rear—to streamline trenching and backfilling. This setup could reduce idle time and improve workflow continuity.
Conclusion
The Mecalac 6MCR is a bold reimagining of compact excavation. Its speed, versatility, and multifunctional boom offer clear advantages for specialized operations, particularly in utility installation and urban excavation. While its complexity may deter some buyers, those who understand its strengths and maintain it diligently can unlock significant productivity gains. As Mecalac continues to expand its footprint, the 6MCR may well become a staple in forward-thinking fleets that value adaptability over convention.
