Detailed Description 

The LIUGONG 922F is engineered to deliver a balanced combination of power, fuel efficiency and durability for demanding earthmoving tasks. Equipped with a Cummins B6.7 engine and variable geometry turbocharging (VGT) technology, this excavator improves torque delivery while controlling fuel consumption — making it an effective choice for contractors, rental fleets and municipal operators who require dependable performance across a wide range of job sites.

At the heart of this machine, the Cummins B6.7 produces 116 kW at 2200 rpm and pairs with three selectable power modes: Power, Standard and Eco. These modes enable operators to match output to task intensity, reducing unnecessary fuel burn in lighter operations. VGT technology improves low-end torque by approximately 5% under typical working conditions, aiding quicker cycle times on heavy digs. A bank of six electronically controlled fans optimizes cooling and reduces auxiliary power draw by up to 60%, contributing to lower operating costs and extended component life.

The 922F’s undercarriage and upper-structure components are reinforced to withstand repetitive stress. The extra-tough chassis design reduces stress concentrations by 10%, while the boom and arm follow a higher-strength specification that reduces structural stress by 30% compared with standard designs — a direct benefit when working in abrasive or high-impact conditions. The electro-hydraulic control system, including boom float and precise attachment flow and pressure control, provides smooth and predictable implement movement that improves cycle repeatability and operator confidence.

With a standard bucket of 1.1 m³ and compatibility across a 0.9–1.4 m³ range, the 922F adapts to material densities from soft overburden to compacted mineral mixes. The machine achieves travel speeds of 5.6 km/h (high) and 3.3 km/h (low), and a maximum swing speed of 10.5 rpm — metrics that combine to reduce repositioning time on site. Breakout forces (arm: 105 kN; bucket: 152.5 kN) ensure effective penetration and load retention when filling trucks or loading stockpiles.

The LIUGONG 922F serves a broad set of use cases where a mid‑to‑large excavator is required. Typical applications include:

• General construction and site preparation — trenching, foundation work, and bulk excavation.
• Road and infrastructure projects — drainage, culvert work and highway maintenance.
• Quarry and aggregate operations — loading, short-reach ripping and secondary breaking.
• Utility and municipal services — pipe-laying, repair work and urban excavation where precise control is essential.

• Equipment rental fleets — a versatile asset that answers the needs of varied customers.
