Product Overview — Flagship 4-Ton Class Performance

The HT35 stands as the largest and most capable model in China’s complete mini excavator product lineup, bridging the gap between traditional mini excavators and full-size compact crawler excavators. With an operating weight of 3989 kg (just under 4 metric tons), it delivers earthmoving capabilities that significantly exceed smaller models while maintaining the maneuverability and transportability advantages that make mini excavators so versatile globally.

At the heart of the HT35 lies the proven Kubota D1703 three-cylinder direct-injection diesel engine producing 18.5 kW (22 HP) @ 2200 RPM. This powerplant drives a high-performance hydraulic system operating at 24 MPa with a flow rate of 79.2 L/min. The result is a 30.4 kN bucket breakout force — the strongest in the entire HT series — combined with an 18.2 kN arm digging force. These figures place the HT35 in a performance tier typically occupied by much heavier machines.

The working envelope is equally impressive: 3106 mm of maximum digging depth, 4938 mm of digging height, and an extraordinary 5175 mm (over 5 meters!) of maximum digging reach. A 0.12 m³ standard bucket capacity ensures maximum material movement per cycle. The HT35 comes standard with a fully enclosed ROPS/FOPS-certified cab, reflecting its positioning as a premium professional-grade machine built for serious contractors and rental fleet operators who demand maximum productivity from their investment.

Key Selling Points — Why the HT35 Stands Out

Flagship 4-Ton Class Power The 30.4 kN breakout force and 18.2 kN arm force represent the absolute peak performance in Shandong Hightop’s mini excavator range. Capable of handling compacted clay, light rock, frozen ground, and demanding earthmoving tasks that smaller machines cannot touch.
Industry-Leading Reach 5175 mm (over 5 meters) of maximum digging reach is exceptional for any machine in this weight class. Enables operators to dig under building overhangs, reach across obstacles, and work around existing structures without frequent repositioning.
24 MPa High-Pressure Hydraulics Professional-grade HP5V45 axial piston pump + HVSE main valve at 24 MPa system pressure with 79.2 L/min flow rate. This combination delivers the hydraulic muscle behind every one of the 30.4 kN breakout force specifications.
Dual-Speed Travel System Variable displacement piston travel motor provides 4.2 km/h high gear for efficient job-site transit and 2.4 km/h low gear for maximum drawbar pull when climbing steep slopes or pushing through difficult ground conditions.
Standard Enclosed Cab Unlike smaller models where the cab is optional, the HT35 comes standard with a fully ROPS/FOPS-certified enclosed cab. Full glass enclosure, sealed door, ergonomic station, and climate-ready design for year-round professional operation.
58% Gradeability Exceptional 58% gradeability enables confident operation on embankments, ramps, hilly job sites, and uneven terrain where many competing machines would struggle or lose traction.
