906FG4 NEW LIUGONG CRAWLER EXCAVATOR

The LiuGong 906FG4 is a 5.5–5.9 ton, China IV emission standard, remote-controlled tracked excavator (a derivative model of the 906F series). It is mainly used for high-risk or confined space operations such as disaster relief and rescue, and hazardous waste disposal. It supports both local and remote control modes.

 

Machine Weight: 5500–5900 kg

 

Standard Bucket Capacity: 0.21 m³

 

Engine: Yuchai YCF3050-T420-3040W (four-cylinder inline, naturally aspirated, water-cooled, China IV emission standard), rated power 36.8 kW @ 2200 rpm, maximum torque 210 N·m @ 1300–1600 r/min

 

Main Performance: Maximum digging height 5700 mm, maximum digging depth 3850 mm, maximum digging radius 6185 mm; bucket ISO digging force 47 kN, stick 31 kN

 

Control: Supports remote/short-range remote control (with emergency stop and attitude detection), manual operation is also possible; swing speed 10.3 rpm, climbing ability 35°

 

Transport Dimensions: Length 5900 mm × Width 1940 mm (standard tracks) × Height: 2570 mm; Minimum ground clearance: 347 mm

 

Typical operating conditions: High-risk or space-constrained scenarios such as earthquake/flood rescue, river dredging, road repair, building demolition, and forestry transportation.

Note: The 906FG4 differs from the regular 906F (weight 5600–6200 kg, both meeting China IV emission standards) in that it is specifically optimized for remote operation, with enhanced structural and electronic control system redundancy for safe remote operation; it is not an electric version, nor is it the "906F Max+" (the latter typically uses Yanmar engines).
