1.8 metric ton mini-excavator

LiuGong North America has launched the first of its new F-series excavators with the 9018F model, a 1.8 metric ton mini-class excavator.

It has been designed to meet or exceed North American market design specifications, and to be a perfect fit for the rental industry and smaller job applications.

LiuGong North America has launched the first of its new F-series excavators with the 9018F model, a 1.8 metric ton mini-class excavator.

Its compact dimensions, foldable dozer blade and retractable undercarriage make it ideal for working in tight spaces and provide flexibility for multiple applications.

The unit is available with a FOPS-rated closed and pressurized cab, featuring heater and window defroster of with a TOPS-rated canopy design. The closed cab 9018F version stands just 7 feet 7 inches tall, resulting in a lower height that eliminates headspace concerns while traveling in restricted spaces or while being transported. 

The 9018F’s short stature combined with a retractable undercarriage give its operator access to the most restrictive workspaces. Its 51-inch outside-to-outside tread measurement retracts to just 39 inches, allowing it to easily pass between onsite obstructions and through almost any bay door. 

Application versatility
“Its versatility is not solely a result of its compact size,” says Christopher Saucedo, vice president and general manager, LiuGong North America. “The 9018F is a powerful, robust base unit for a variety of attachments, and supports the installation of consumer-requested aftermarket add-ons.”

9018F Specifications (Cab)

  • Operating weight (with cab): 4,189 lb. 

  • T4F Yanmar engine: 18.0 hp (gross)

  • Max pump flow rate: 14.5 gpm

  • Max pressure: 3,046 psi

  • Standard bucket capacity: 0.06 yd3

  • Bucket/cutting width: 19.7 in

  • Bucket breakout force: 3,597 lbf • Arms stick force: 2023 lbf

  • Digging depth: 7 ft. 5 in. • Swing speed: 9.5 rpm  • Arm length:3 ft. 5 in.

  • Max dump height: 7 ft. 7 in. (digging height 11 ft. 1 in.)

Back-filling or dozer operation no longer requires the operator to remove his or her hand from blade control to change travel speed. By simply pressing the top of the handle, an operator can now select high or low speed travel. Standard 9018F features include a low-speed, high-torque, Tier 4 Final Yanmar engine rated at 18.0 gross hp, as well as auto-idle and auto shutdown.

Better fuel consumption is achieved through a more efficient hydraulic system using 15 to 20 percent less engine power than that of its predecessor. An improved load-sensitive hydraulic system with 14.5 gpm main pump displacement utilizes a proportional control valve for better management of flow distribution for all attachments, all of which allow the user more precise operation. 

Flow rate for the hammer-shear and hydraulic thumb is set right from the operator’s monitor. A LiuGong hydraulic thumb  comes standard with the unit. 

Travel pedals and joysticks give an operator hydraulic control for machine functions: travel, boom swing, arm and bucket. Auxiliary hydraulic functions are controlled by electrical, proportional solenoids for precise control.
