Compared with previous generations of LiuGong excavators, F-series models 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.
LiuGong F-series excavators comply with the latest emissions regulations in China and Europe. The series has 15 product sub-platforms with over 40 size classes ranging from 1.5 to 90 tons. This covers more than 90% of the global market demand.
In addition to basic models, F-series excavators also have variants. Appropriate attachments are used to serve different purposes, including excavation, demolition, forestry, material handling and recycling, providing customers with best value.
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 installed on each excavator, which controls the fan speed in real time according to the temperature of water, oil and intercooler. With these systems, F-series excavators are able to offer high operating efficiency and low oil consumption - 15%-20% lower than that of the previous generation of excavators.
LiuGong says its F-series excavators have also been greatly improved in terms of their operation intelligence, which combines the integrated operation of a single excavator, intelligent control, network-based integration of excavators, intelligent monitoring, detection, prediction and remote control. This technology enables the monitoring of bucket trajectory, construction guidance, assisted excavation and automatic weighing, significantly improving the working efficiency and quality and avoiding repeated operation. The excavators also adopt new electronic fence technology that ensures safer construction, and expandable control platform that provides the basis for access to the intelligent control and management system of excavators.
The 990F is one of seven LiuGong F-series excavators on show at BICES 2019 - the 15th China Beijing International Construction Machinery, Building Material Machines and Mining Machines Exhibition & Seminar – taking place 4-7 September.
A sixth-generation intelligent hydraulic excavator, the 990F adopts a fully electronically controlled advanced hydraulic system, heavy-duty structure and optimised crushing design. Said to boast excellent operating efficiency, low oil consumption and high reliability, the machine can be used for excavation loading and crushing in quarries and open-pit, phosphate and metal mines.
