In small-scale construction projects, compact size, efficiency, and reliability are essential to improving productivity. The CX12-6 hydraulic mini excavator from Ningbo ACE Machinery Co., Ltd. integrates practical design with stable performance, making it a suitable choice for interior renovation, landscaping, and work in confined or narrow environments. The following provides an objective overview of its main features and advantages.
Compact Structure and Flexible Operation for Confined Areas
One of the key strengths of the CX12-6 is its compact yet capable design. With an operating weight of 1200 kg, an overall length of 2980 mm, and a total height of 2260 mm, combined with 180 mm wide rubber tracks and an adjustable track gauge, the machine is well suited for narrow indoor spaces and restricted job sites. The zero-tail swing configuration ensures that the rear of the excavator remains within the track width during operation, reducing the risk of collisions and improving safety when working close to walls or obstacles.
The machine is equipped with hydraulic pilot control levers and integrated wrist rests, enabling precise and responsive operation while minimizing operator fatigue during extended use. A swing speed of 8.3 rpm and a dual travel speed of 2/4 km/h allow smooth transitions between traveling and working. The foot pedal-controlled auxiliary hydraulic circuit (AUX1) further increases compatibility with various attachments and working conditions.
Efficient, Low-Emission Power System
The CX12-6 is powered by the Kubota D722-EF18-CN14 water-cooled diesel engine, featuring the E-TVCS three-vortex combustion system for high fuel efficiency and stable output. The engine delivers a net power of 10.2 PS at 2500 rpm, with maximum digging forces of 5.4 kN for the dipper arm and 10.4 kN for the bucket, supporting efficient excavation, leveling, and material handling tasks.
In compliance with Stage V emission standards, the engine significantly reduces exhaust emissions and operating noise, which is limited to approximately 77 dB(A). This contributes to a more environmentally friendly operation and a quieter, more comfortable working environment. The 12-liter fuel tank and optimized fuel system provide extended operating time and reduce the frequency of refueling.
Operator-Oriented Design for Extended Working Comfort
Comfort and safety have been carefully considered in the CX12-6 design. An LED work light mounted on the boom improves visibility in low-light or nighttime conditions. Optional safety features such as a rollover protection structure (ROPS) and canopy enhance operator protection and operational confidence.
Vibration control meets international standards, with hand-arm vibration levels below 2.5 m/s² and whole-body vibration below 0.5 m/s². These measures help reduce physical strain during long working hours. The ergonomic layout of controls and wrist support contributes to smoother operation and improved overall comfort.
Simplified Maintenance and Durable Construction
Ease of maintenance plays a key role in reducing operating costs. The CX12-6 features a fully opening engine cover, providing direct access to major components for daily inspection and routine servicing. This design minimizes downtime and simplifies maintenance procedures.
The hydraulic system incorporates internal routing of service port pipes within the boom, protecting them from external damage and allowing convenient pressure checks at the boom end. The two-stage hose configuration for the bulldozer hydraulic cylinder enables faster on-site hose replacement. A dual-element air filter enhances engine protection, while the 180 mm rubber tracks and double-flange idler wheels on each side offer durability across different ground conditions. The integrated battery isolator further protects the electrical system and extends component lifespan.
Comprehensive Safety and Anti-Theft Measures
The CX12-6 is equipped with multiple safety systems, including an engine start safety mechanism, hydraulic locking system, and control lever lock, all designed to prevent unintended operation. These features help ensure safer handling during both operation and maintenance.
For equipment security, the excavator includes Kubota’s anti-theft system, which allows the engine to start only with a programmed key. Unauthorized start attempts trigger an alarm, while visual LED indicators signal that the security system is active. A key-removal reminder further reduces the risk of theft and enhances overall asset protection.
Conclusion
With its compact dimensions, efficient and compliant powertrain, operator-focused comfort features, simplified maintenance, and comprehensive safety systems, the CX12-6 mini excavator from Ningbo ACE Machinery Co., Ltd. is well suited for a wide range of small-scale construction applications. It provides a balanced solution for contractors and operators seeking reliable performance in confined environments while maintaining efficiency and safety throughout daily operations.
