LIUGONG 906FG4 EXCAVATOR

​​Liugong 906FG4 Remote Control Excavator: Resilient Efficiency for Extreme Operations

The LIUGONG 906FG4 is a 6,020 kg (13,272 lbs) mini excavator engineered for medium-duty work across residential, municipal, and agricultural job sites. With a 39.5 kW high-torque engine, 4,020 mm max digging depth, and 2,780 kg lifting capacity, it balances power and agility—ideal for professional operators and skilled newcomers tackling construction, landscaping, or infrastructure auxiliary tasks.

Introduction

The product is engineered to perform remote excavation tasks in hazardous environments with precision. Featuring a robust Yuchai engine meeting China IV emission standards and dual remote/local operational modes, this 5,900 kg excavator combines safety with versatility. Whether tackling disaster rescue, hazardous waste handling, or complex site projects, the 906FG4 provides remote-controlled efficiency and multi-layer safety assurance to complete high-risk jobs reliably.

Key Features

The product boasts several key features that set it apart:

1. Dependable Power Performance: Equipped with a 39.5 kW engine and 182 N·m torque @ 1,600 rpm, it offers a 2,780 kg lifting capacity—effortlessly handling 140 kg (309 lbs) concrete blocks or small steel parts.
2. Precision Hydraulic System: 27.5 MPa system pressure paired with a dual-pump design delivers 5.0 m/s boom speed and 6.8 m/s arm speed, achieving fast cycle times (9.5 seconds per load with 0.27 m³ bucket).
3. Compact & Agile Design: With an overall width of 2,060 mm and zero-tail-swing (0 mm rear overhang), it easily passes through 2.1 m (6.89 ft) narrow gates or construction site passages.
4. Outstanding Fuel Economy: Consumes just 4.8-5.5 L/h (1.27-1.45 gal/h) under 70% load. The 115 L fuel tank supports 21-24 hours of non-stop work, reducing refueling frequency.
5. Robust & Durable Build: High-strength steel boom and arm (15 mm thickness), wear-resistant bucket (HB380 steel with 19 mm cutting edge), and 380 mm wide rubber tracks (service life ≥2,000 working hours) ensure long-term reliability.
6. All-Round Safety Protection: 360° panoramic visibility (3.9 m² cab window area) and ROPS/FOPS-certified frame, plus anti-slip steps and emergency stop button, minimize blind spots and protect operator safety.

Parameters

Working Scene

The LIUGONG 906FG4 adapts to a wide range of medium-duty scenarios:

• Residential & Construction: Excavates 3.9 m deep foundations (matching 12.8 ft basement height), loads 0.27 m³ soil buckets (28 loads per hour), or handles home renovation demolition (9 m² wall per hour with hydraulic breaker).
• Municipal Engineering: Trenches 0.5 m wide × 1.8 m deep for water/gas pipelines (140 m length in 3 hours), repairs roads by lifting 1,800 kg asphalt slabs, or supports urban greening (22 holes per hour for tree planting with 500 mm auger).
• Agriculture & Farming: Digs irrigation ditches (0.7 m wide × 1.4 m deep, 110 m in 2 hours), lifts 2,400 kg steel beams for barn construction, or levels farmland (1,100 m² in 4 hours with 0.27 m³ grading bucket).
• Indoor & Commercial Projects: Facilitates warehouse expansion (≤69 dB noise and zero tail swing) or mall basement repairs (2,060 mm width fits standard large elevator doors of 2,100 mm).

Optional Accessories

All accessories come with clear performance specifications:

FAQ

Q: What is the actual digging efficiency? How much soil can it move per hour?

A: With a 0.27 m³ bucket, it completes 65-75 loading cycles per hour (9.5 seconds per cycle), moving 17.55-20.25 m³ (22.95-26.49 yd³) of soil per hour (based on loose soil density of 1,600 kg/m³).

Q: How does fuel consumption vary with workload?

A: At 50% load (grading), it consumes 4.8 L/h (1.27 gal/h); at 70% load (digging), 5.1 L/h (1.35 gal/h); and at 90% load (lifting 2,500 kg), 5.5 L/h (1.45 gal/h).

Q: What is the track service life? Is replacement easy?

A: Rubber tracks last ≥2,000 working hours on concrete/paved surfaces or ≥1,700 hours on muddy/rocky terrain. Replacement takes 1.8 hours with standard tools. 

Q: How often should hydraulic oil be changed, and how much is needed?

A: Hydraulic oil should be changed every 500 working hours. It requires 62 L (16.38 gal) of ISO VG46 hydraulic oil. 

Q: Can it work at high altitudes? What is the power loss at 3,000 m?

A: It can operate at altitudes up to 3,000 m. At 3,000 m, power loss is approximately 8% (from 39.5 kW to 36.3 kW) due to thinner air.

Q: What is the turning radius? Can it rotate in confined spaces?

A: Inner turning radius is 2,450 mm (8.04 ft), and outer turning radius is 4,420 mm (14.50 ft). It can fully rotate in a 5 m × 5 m (16.40 ft × 16.40 ft) area, making it suitable for residential yards or small construction sites.
