LiuGong launched its sixth-generation F-series excavators at the BICES 2019 exhibition in Beijing, China. Like its predecessors, the latest generation models integrate cutting-edge technology, intelligence and environmental protection features.

The new F-series excavators are mainly designed for North America, Western Europe, and China but are also relevant to emerging market customers, as LiuGong offers various product portfolios to meet the needs of different markets.

F-Series excavators are greater in number and class sizes than previous generation models. They include standard units for the Chinese market and short-tail and zero-tail swing models for the Western European and North American markets. The machines comply with the latest regulations of China and Europe on emissions. The F-Series has 15 product sub-platforms with over 40 size classes ranging from 1.5 to 90 tonnes, which covers more than 90% of the global market demand. Mini excavators of less than six tonnes are divided into further size classes.

LiuGong F-series excavators are equipped with the latest electronically controlled hydraulic system consisting of a main pump with large displacement, a low-speed and high-torque engine and a main electro-hydraulic proportional control valve for better management of flow distribution. An intelligent cooling system is also equipped, which controls the fan speed in real time according to the temperature of water, oil and intercooler. With these systems, the F-series excavators are industry-leading in terms of their high operating efficiency and low oil consumption (about 15-20% lower than that of the previous generation of products).

In addition to the features of energy conservation and high efficiency many other LiuGong excavators have, the F-series excavators have been greatly improved in terms of product intelligence. This combines the integrated operation of a single excavator, intelligent control, network-based integration of excavators, intelligent monitoring, detection, prediction and remote control. The technology enables the monitoring of bucket trajectory, construction guidance, assisted excavation, automatic weighing, etc., significantly improving the working efficiency and quality and avoiding repeated operation.
