Product Introduction
Compact Powerhouse for Versatile Operations
The H12 is a robust mini excavator engineered for demanding construction environments, featuring a 900 kg operating weight and 0.03 m³ bucket capacity. This agile machine delivers impressive digging capabilities with a maximum depth of 3,250 mm and lifting height of 2,900 mm, complemented by a 2,100 mm unloading height for efficient material handling. Its compact footprint—measuring 3,240 mm in length, 990 mm in width, and 2,200 mm in height—ensures exceptional maneuverability in confined spaces. With a travel speed of 0-1.8 km/h and 11% gradeability, the H12 navigates challenging terrain effortlessly, while the minimal 800 mm tail swing radius enhances safety in tight working quarters.
Reliable Kubota Powertrain
At the heart of the H12 lies the dependable Kubota Z482 diesel engine, producing 9.8 kW of maximum power at 3,600 rpm. This fuel-efficient two-cylinder, oil-cooled power unit is designed for longevity and runs on standard diesel grades for reduced operational costs. The excavator is equipped with durable steel tracks (180×72×37 configuration) providing superior traction and stability across diverse surfaces. The well-designed hydraulic system incorporates an 18-liter hydraulic oil tank and a 5.5-liter fuel tank, optimizing performance while minimizing downtime. Mechanical track tensioning ensures consistent track integrity, supporting reliable continuous operation in professional applications.
Thoughtful Design and Standard Features
The H12 comes generously equipped with practical standard features including a protective operator ceiling, versatile side swing functionality, and chassis extension capability for enhanced stability. The integrated bulldozer blade, measuring 950 mm by 235 mm, delivers 190 mm of maximum lift and dig height for efficient site grading and backfilling operations. While counterweights and air conditioning remain optional, the standard mechanical tensioning system and compact 1,470 mm minimum turning radius ensure productive, hassle-free operation. These thoughtful design elements make the KX12-CK an ideal choice for contractors seeking a capable, transportable excavation solution without compromising on essential functionality.

Applications
Urban Construction & Renovation: Perfect for digging foundation trenches for garden walls, small extensions, or repairing underground utility lines (water, gas, fiber optics) in narrow alleys, backyards, and between closely spaced buildings. Its minimal width of 930mm allows easy access through standard gates.
Landscaping & Gardening: Excellently suited for creating ponds, planting trees, digging irrigation channels, and precise terrain shaping in parks, residential gardens, and commercial landscapes. The 0.03m³ bucket is optimal for detailed earthmoving.
Indoor & Demolition Work: Capable of operating inside factories, warehouses, or basements for floor-breaking, controlled interior demolition, and material handling, thanks to its compact size and efficient engine.
Agricultural & Rural Use: An indispensable tool for farmers and landowners for tasks such as digging drainage ditches, cleaning ponds, fence post installation, and general farm maintenance.
Municipal Utilities: Highly effective for street repair, sidewalk maintenance, signpost installation, and other public works in congested urban areas, minimizing disruption and traffic closure.
Packaging & Shipping
Export-Grade Packaging and Secure Shipping
To ensure your mini excavator arrives in optimal working condition, KMX implements a comprehensive export-standard packaging and shipping process. Each unit is securely mounted on a reinforced steel-frame skid and fully wrapped in high-strength waterproof film, providing complete protection against moisture, dust, and physical damage during transit.
For international shipments, excavators are loaded into standard 20ft or 40ft high-cube containers using specialized handling equipment. Inside the container, heavy-duty straps and custom bracing materials are applied to immobilize the equipment, preventing movement and ensuring secure delivery worldwide. This end-to-end approach guarantees your machinery remains in pristine condition throughout the global logistics chain.
