Product Description
922F is a new-generation 22-tonne hydraulic excavator independently developed by Liu Gong. It adopts fully electronically-controlled hydraulic system and intelligent heat dissipation technology, and the whole machine features high operating efficiency, low fuel consumption and low noise, and is configured with a variety of modes of operation such as excavation, grading, crushing, lifting, etc., which is suitable for all kinds of earthmoving projects such as highway, construction, water conservancy, mining, and so on.
Key Features:
Three new power modes of 922F - Power, Standard and Eco. Using VGT technology engine, delivers 5% more torque. 6 electronic fans, reduce power consumption by 60%
Extra tough chassis - reduces stress by 10%; extra strong boom & arm - reduces stress by 30%.
Electro-hydraulic control technology, boom float technology and attachment flow and pressure control, all these make the operation more convenient.
Equipped with 360 degree camera and around level daily inspection.
The NVH design reduces wind resistance and noise. Compared with traditional direct-drive fans our new electronic fans are quieter by 9%.The external radiated noise of the machine is best in class at 68dB.
Applications:
Construction of public facilities
Road construction
Demolition of houses
Oil and gas pipeline construction
Agriculture, forestry, landscaping
