The KMZ40 Zero Tail Excavator Launches Worldwide: Redefining the Benchmark for Green Construction in the 4-Ton Class
The KMZ40 Zero Tail Excavator Launches Worldwide: Redefining the Benchmark for Green Construction in the 4-Ton Class
—— Kubota's Euro V Powertrain + Fully Electronically Controlled Hydraulic System Leads a New Era of Low-Carbon Construction
As the "Dual Carbon" strategy drives the green transformation of construction machinery, Kaiman Machinery today officially launched the all-new KMZ40 Zero Tail Excavator. Equipped with a Kubota D1703 Euro V/EPA4-certified engine, this excavator reduces fuel consumption by 20% through its ECO intelligent fuel-saving mode. Combined with its fully electronically controlled hydraulic system, it is the industry's first 4-ton excavator to meet both EU Stage V and US EPA Tier 4 final emission standards.
Three Revolutionary Technological Breakthroughs
1.Green and Efficient Power Core
Kubota Low-Noise Engine: The 3-cylinder turbocharged design achieves 18kW rated power and 217N·m peak torque, while idling noise is kept below 57dB(A), a 40% reduction compared to conventional engines.
Dual-Stage Fuel Filtration System: Equipped with dual precision filters, it effectively blocks micron-sized impurities, extending engine life by 30%.
ECO Intelligent Operating Mode Matching: Automatically detects light-load conditions and switches to energy-saving mode, achieving a measured combined fuel consumption of just 4.2L/h.
2.Innovative Human-Machine Interaction
Panoramic Cockpit: Featuring a retractable windshield (opening up to 75°), 800mm of flat legroom, and a suspended seat, it supports rapid emergency evacuation.
LED Smart Instrument: Integrates oil pressure monitoring, real-time fault code diagnosis, and workload statistics, improving maintenance response efficiency by 50%.
Fully Opening Hood: The hinged lift-up design reduces daily maintenance time to 15 minutes.
3.Upgraded Adaptability for All Scenarios
Dual-Mode Track System: Standard steel tracks (ground pressure 32kPa) cope with rock-crushing conditions in mines; optional rubber tracks (adjustable width 990-1300mm) minimize damage to municipal roads.
Electrically Controlled Proportional Valve Joystick: Controls over 20 attachments, including breakers and augers, with 0.1mm accuracy, improving retooling efficiency by 60%.
Zero Tail Swing: With a tail swing radius of only 860mm, it enables 360-degree operation in alleys as narrow as 1.8 meters.
Policy and Market Positioning
The KMZ40 precisely aligns with the "new energy alternatives for construction machinery" requirements outlined in the State Council's "Opinions on Promoting Green and Low-Carbon Transformation and Strengthening Carbon Market Construction." It is one of the first domestically produced machines to receive the CE certification. Currently, orders for this model can reach 100 units at a time, with a 45% market share in Europe.
