HT45 Wheeled Mini Excavator — 4.5-Ton Class
Shandong Hightop Group · ZN490 34 kW Water-Cooled Diesel · 55.6 kN Breakout Force · Road-Speed Travel 4.6 km/h · Adjustable Chassis · Multiple Colors
💪 55.6 kN Force
🚗 4.6 km/h Travel
🪣 0.26 m³ Bucket
📐 557 mm Clearance
The HT45 is China’s flagship wheeled mini excavator, operating at 4500 kg (4.5-ton class). Unlike the crawler-based HT series models, the HT45 rides on a robust wheeled undercarriage with 557 mm tire ground clearance and road-speed travel capability of 4.6 km/h — allowing direct road travel between job sites without lowbed transport equipment.
Powered by a ZN490 water-cooled diesel engine producing 34 kW, the HT45 delivers 55.6 kN bucket breakout force — the highest breakout force in the entire HT mini excavator lineup — with a 0.26 m³ bucket capacity for maximum material-per-cycle productivity. The 22 MPa hydraulic system with a 99 L/min flow rate and 32 cm³ piston pump ensures fast, responsive operation across all attachments.
With an adjustable chassis width (1530/1600 mm), 35° gradeability, and a minimum tail swing radius of just 1170 mm, the HT45 combines large-excavator power with the access flexibility needed for road corridors, utility trenching, agricultural fields, and urban construction sites. Available in multiple factory colors with full OEM private-label support.

Engine System
ZN490 Water-Cooled Diesel Engine
• Type: Water-Cooled Diesel
• Rated Power: 34 kW
• Cooling: Water-cooled for stable temperature control under heavy continuous duty cycles
• Fuel Tank Capacity: 60 L — full working day without refueling
• Engine Oil Capacity: Standard commercial specification
The ZN490 water-cooled diesel provides the 34 kW needed to simultaneously drive the 99 L/min hydraulic system at 22 MPa while maintaining robust wheeled travel performance. The water-cooled architecture is essential for sustained operation in hot-climate markets across Africa, Southeast Asia, and the Middle East.

6 Key Advantages of the HT45
|
🚗 Road-Speed Wheeled Mobility
Travel at 4.6 km/h on public roads — reposition between urban job sites, utility corridors, and road works without a lowbed trailer. Dual-speed piston motor for powerful low-speed digging and fast high-speed transit. |
💪 55.6 kN Breakout Force — Highest in HT Range
The HT45 delivers the highest bucket breakout force across all HT mini excavator models. Break compacted soil, cut through roots and clay, and handle light demolition work with confidence. |
|
🪣 0.26 m³ Bucket — Maximum Productivity
The largest standard bucket in the HT mini excavator lineup. More material moved per cycle means faster trench completion, lower labour cost per cubic metre, and better utilization of operator time. |
📐 557 mm High Clearance Chassis
557 mm tire-to-ground clearance enables access across rutted agricultural fields, orchard rows, rough construction sites, and uneven terrain where low-clearance tracked machines would become grounded. |
|
⚙️ Adjustable Chassis 1530/1600 mm
Narrow configuration (1530 mm) for access through gates, alleyways, and tight urban spaces. Wide configuration (1600 mm) for maximum stability during heavy digging operations and slope work. |
🎨 Multiple Colors + OEM Private Label
Available in multiple factory colors as shown by the product color swatch. Full OEM private-label capability: your logo, your colors, your documentation. CE / EPA / ISO 9001 certificates for all export markets. |
