CONEXPO LIVE: LiuGong
LiuGong’s new F-series excavators may have debuted at BICES2019 last September, but their appearance at today’s CONEXPO-CON/AGG in Las Vegas is still significant for the US market and the Chinese company. In LiuGong’s own words, “As the sixth-generation excavators integrating technology, intelligence and environmental protection, they were extremely important for LiuGong to meet the future market needs.”
The new F-series excavators are mainly designed for North America, Western Europe, and China, while taking into account the emerging markets. Compared with the previous generations of excavators, the F-series excavators have more models and size classes, including standard ones for the Chinese market and short-tail and zero-tail swing ones for the Western European and North American markets.
The machines comply with the latest regulations of China and Europe when it comes to emissions. The series has 15 product sub-platforms with over 40 size classes ranging from 1.5 to 90 tons, which covers more than 90% of the global market demand. Mini excavators of less than 6 tons are divided into more size classes. In addition to basic models, the F-series excavators can be teamed with various accessories to serve different purposes, including excavation, demolition, forestry, material handling, and recycling, and providing customers with the best value.
LiuGong says the 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, LiuGong reckons its F-series excavators are industry-leading in terms of their high operating efficiency and low oil consumption (about 15 to 20% lower than that of the previous generation of products).
The F-series excavators also 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 and so on, which should improve working efficiency.
