The all-round narrow-alley excavator, the KMZ28, has been launched globally.

—Hydraulic four-link synchronized control and intelligent load-bearing system redefine the performance of compact equipment.

Kima Machinery recently officially launched the all-new KMZ28 zero-tail mini excavator. This model features a zero-tail swing design, with a reduced swing radius of 860mm at the rear, enabling free maneuvering in 1.5-meter-wide lanes. This eliminates the pain points of traditional equipment being prone to collision and damage in narrow lanes, interior renovations, and orchard management. Its four-link hydraulic synchronization system enables seamless coordinated operation of the boom, arm, bucket, and swing movements. Combined with a 23.5kN bucket digging force and a 14kN arm digging force, it delivers a 30% improvement in operating efficiency compared to similar models.

Four Key Technological Innovations

1. Ultimate Maneuverability

• Zero-Tail Structure + Expandable Chassis: The tail swing radius is only 860mm, and the rubber track width is electrically adjustable (standard width is 1550mm), ensuring both narrow passage and stability on slopes.

• Swinging Boom Design: Supports ±45° horizontal swing, and combined with a cylinder top protection structure, it prevents collisions during corner operations and enables single-step excavation in blind areas.

• Dual-Mode Counterweight System: In addition to the standard cast iron counterweight, modular counterweights can be added, improving stability in tilting conditions by 40%.

2. Intelligent Precision Control System

• Hydraulic Pilot Load Sensing: A flow-sensitive pump (67.2 L/min, 22 MPa) that adapts to load demands in real time delivers millimeter-level accuracy and reduces energy consumption by 25%.

• Proportional Solenoid Valve Joystick: An optional electronically controlled proportional valve handle enables millimeter-level fine-tuning of attachments, supporting over 20 quick-change attachments such as breakers and augers.

• S40 European standard quick-change connector: Attachment replacement time is reduced from 15 minutes to 30 seconds, compatible with the entire KIMA accessory ecosystem.

3. Ergonomic Innovation

• Panoramic Cockpit: Equipped with a suspended seat and adjustable armrests, the cabin offers 800mm of legroom. Combined with an optional all-directional air conditioning system, it reduces fatigue during continuous operation by 60%.

• Multi-stage Shock Absorption: A three-stage shock-absorbing chassis and a silicone-sealed cab keep noise levels below 57dB(A), meeting urban nighttime construction standards.

4. Multi-scenario Durable Design

• Cylinder Anti-collision Armor: Key hydraulic cylinders are equipped with 360° protective steel plates to protect against stone impact and metal scraping.

• Long-lasting Anti-corrosion Coating: The entire machine utilizes a cathodic electrophoretic coating combined with powder spraying, resulting in over 1200 hours of salt spray corrosion resistance, three times the lifespan of traditional wet paint.

Market Service Upgrade

• The KMZ28 offers a "1+1" full-lifecycle warranty:

• A one-year full machine warranty or 2,000 hours, whichever comes first, with global coverage in over 50 countries;

• An optional three-year extended warranty service package includes a dedicated technical consultant and 48-hour fault response.

Industry Reviews

"The KMZ28 redefines the performance threshold for compact equipment. Its zero-tail design not only reduces its physical size, but also achieves the operational efficiency of a large machine in confined spaces through the integration of four-axis hydraulic synchronization and load-sensing technology."
