HT-12G / HT12 Mini Excavator — 1.2-Ton Crawler Digger with Kubota Water-Cooled Diesel Engine & Enclosed Cab Option

The HT-12G / HT12 represents China’s premium entry into the compact diesel mini excavator segment. Built around a robust 1200 kg operating weight platform with a class-leading 3000 mm maximum digging depth, it is powered by a genuine Kubota 3-cylinder water-cooled diesel engine (D722 or Z482 model, 10.2 kW @ 2500 rpm) delivering superior low-end torque and all-day runtime efficiency that gasoline alternatives cannot match. Available in two configurations: the HT-12G ships factory-fitted with a fully enclosed cab for all-weather protection, while the HT12 features an open canopy design with an optional add-on cab kit for flexible fleet deployment. Additional premium features include a German-manufactured dual-stage air filtration system, optional Eaton USA hydraulic travel motor, large-capacity 20 L diesel and hydraulic fluid tanks, EPA/CE/ISO certification readiness, and complete OEM private-label customization for global construction equipment distributors.

Cab Configurations — Two Variants Available

HT-12G (Left Image)	Factory-fitted enclosed cab — full steel enclosure with doors, windows, and overhead roof. Protects operator from sun, rain, wind-blown dust, cold weather, and noise. Total height with cab: 2270 mm. Ideal for year-round professional use, rental fleets, and markets requiring operator safety compliance.
HT12 (Right Image)	Open canopy with ROPS frame — lightweight, excellent visibility, lower total height (2219 mm). Optional add-on cab kit available for retrofitting. Ideal for cost-conscious buyers who want flexibility, warm-climate operations, and easy transport through low-clearance spaces.
Operator Station	Adjustable operator seat, dual-lever pilot controls with intuitive layout, instrument dashboard panel
Boom Swing	Standard — enables parallel-to-wall digging along building foundations, fence lines, and trenches without repositioning the machine

Key Differentiators — Why Choose the HT-12 Series

1. Genuine Kubota Diesel Engine	Unlike most 1-ton mini excavators that run on small gasoline engines, the HT-12 uses a genuine Kubota 3-cylinder water-cooled diesel engine (D722/Z482). Delivers higher torque at low RPM, 30–50% better fuel economy during long work days, dramatically longer engine life (5000+ hour typical), and diesel fuel availability at virtually any job site worldwide.
2. Class-Leading 3000 mm Dig Depth	With a 3000 mm maximum digging depth, the HT-12 outperforms most competitors in its weight class (typically 1500–1800 mm). This means deeper utility trenching, foundation excavation for small structures, tree stump removal, and drainage installation without upgrading to a larger, more expensive machine.
3. German Air Filtration System	German-manufactured dual-stage air filtration with primary filter element and dual pre-filter intake tubes. Critical for protecting the precision Kubota diesel engine in dusty construction sites, sandy environments, agricultural fields, and demolition debris conditions where ordinary filters clog rapidly.
4. Large-Capacity Fuel & Hydraulic Tanks	20 L diesel fuel tank plus 20 L hydraulic fluid tank — both significantly larger than typical 1-ton class capacities. Means fewer refueling stops, longer continuous work cycles, reduced operator downtime, and higher daily productivity per machine.
5. Eaton Travel Motor Option	Optional Eaton (USA) hydraulic travel motor upgrade available for customers demanding maximum component durability. Eaton motors are recognized globally for reliability in harsh-duty applications, offering longer seal life, smoother speed modulation under load, and easier parts sourcing in international markets.
6. Dual Cab Configuration Options	Order either HT-12G with factory-installed enclosed cab for immediate all-weather deployment, or HT12 with open canopy plus optional cab kit for budget flexibility. Both configurations share identical mechanical specifications, engine, hydraulics, and working range — only the cab differs.
