LiuGong has used the backdrop of the 15th Beijing Worldwide Development Equipment Exhibition & Seminar (BICES 2019) in China to launch a brand new vary of battery-electric automobiles (BEVs) in addition to distant managed ‘clever’ wheel loaders primarily based on 5G expertise.
At BICES 2019, LiuGong is displaying three BEVs, together with two excavators – the 906E-EV and 922F-EV – and the corporate’s star wheel loader, the 856H-EV (pictured).
Whereas not all these machines shall be sufficiently big to have mining purposes, LiuGong defined that the models had been very a lot the beginning of a platform that might see larger machines manufactured.
Edward Wagner, Government Director of LiuGong New Expertise, mentioned the overall working value of a battery powered earthmover is, or quickly shall be, “relying on the precise car design and buyer software, decrease than that of a diesel-powered machine”.
LiuGong’s new BEVs are designed for the brand new electrical economic system, it mentioned, with a state-of- artwork, however effectively confirmed, lithium-ion battery system for vitality storage.
“That energy is directed into tremendous excessive effectivity everlasting magnet electrical motors to create the movement essential to drive the machines,” it mentioned. “The machine’s mechanical and hydraulic programs have been optimised for top effectivity: a typical BEV may have peak energy output that’s two occasions a standard diesel energy machine. This permits the battery electrical earthmovers to speed up quicker and carry out extra coordinated actions.”
These actions can even be extra exact given the total digital car management, in accordance with LiuGong. “Extra highly effective, faster and extra exact all add as much as extra productiveness, which is raised greater than 10% in comparison with that of a diesel machine,” the corporate mentioned.
These lithium-ion batteries are designed to final the total lifetime of the machine and get rid of the day by day upkeep and common service routine that comes with diesel engines.
The primary era of LiuGong’s BEVs batteries are outfitted with quick charging expertise and progressive energy-saving applied sciences, in accordance with the corporate. This sees them want just one hour to cost the battery to 80% capability.
Zeng Guang’an, Chairman of LiuGong Group, on the launch ceremony for LiuGong’s BEVs, mentioned: “We’re dedicated to creating extra worth for our clients. And that’s the reason LiuGong won’t ever cease impartial innovation.”
The LiuGong’s 906E-EV excavator is an instance of how rapidly and simply a diesel machine will be transformed to battery electrical, the corporate mentioned. This machine makes use of a lot of the diesel excavator’s hydraulic system permitting for a really fast conversion time. It’s outfitted with a battery massive sufficient for a full working day, in accordance with the corporate.
The brand new 922F-EV excavator is pushed purely by electrical energy, with the battery pack situated centrally within the rear for optimum mass steadiness. The electrical motor and hydraulic system have been optimally packaged to maximise operator visibility, LiuGong says. “The result’s trade main operator visibility which can additional improve efficiency and effectivity.”
A function of the brand new 856H-EV wheel loader is a pure electrical driveline with regeneration. This improves working efficiency and reduces the vitality consumption.
LiuGong defined: “The hydraulic system is electrically pushed whereas utilizing confirmed off the shelf elements. Efficiency is unbelievable given the 300-plus-kW peak energy functionality.”
All three machines are designed utilizing a brand new platform technique, which implies a really excessive diploma of commonality of components and programs throughout all LiuGong’s new vitality machines. “This simplification of components will additional decrease the overall value of possession,” it mentioned.
LiuGong launched the corporate’s first clever shovel distant management wheel loader at its 60th anniversary celebration final 12 months and, at BICES, it has introduced its new 5G-based remote-control clever wheel loader, co-developed and supported by China Telecom and Huawei expertise.
In keeping with Cai Dengsheng, Deputy Chief Engineer of LiuGong’s Clever Expertise Establishment, the mannequin will be remotely managed from over 2,000 km away, in contrast with 2 km as of final 12 months, realising real-time response and correct management by means of the 5G community.
This 5G community is essentially the most superior community communication expertise on the planet with solely 30 millisecond information transition from Beijing to Liuzhou, in accordance with LiuGong. “In the meantime, the transmission high quality or stability should not influenced by both a posh setting or lengthy transition time,” the corporate mentioned. “It’s the finest technical answer for well timed, environment friendly and high-quality transmissions of enormous quantities of knowledge.”
The corporate added: “It supplies a high-quality community setting and community expertise help for LiuGong’s distant management driving analysis and supplies sturdy help for the mixture of edge calculation and cloud computing in clever management underneath distant management situations.
“As one of many few Chinese language development equipment firms that has mastered the 5G expertise, LiuGong is predicted to grasp remote-control driving from even longer distances underneath this platform.”
As well as, LiuGong’s clever shovelling wheel loader can sense materials penetration; has one backside loading and dumping perform, together with auto levelling and controllable placement of the bucket. It additionally options an clever throttle management system, the corporate mentioned.
Beneath remote-control driving mode, all operations will be noticed from the movies which are despatched again by the machines’ cameras. It additionally applies the clever safety expertise to grasp automated identification and auto emergency cease.
Consequently, the machine cannot solely be utilized in its regular purposes, but in addition will be utilized in harmful and unsafe environments akin to rescue and catastrophe aid.
Along with the BEV and 5G releases, LiuGong used the occasion to launch 4 new excavators in its F-Sequence vary which have mining purposes.
The 922F is a new-generation 22-ton hydraulic excavator. It and the opposite F-Sequence automobiles include a totally electronically managed hydraulic system and clever warmth dissipation expertise, with the excavator boasting excessive working effectivity, low oil consumption and low noise.
It has “distinctive engine matching expertise and new P/S/E mode guarantee greater effectivity and low oil consumption”, the corporate mentioned.
The corporate additionally launched the 926F 25-ton hydraulic excavator, the 936F 36-ton excavator with 1.7 cu.m bucket and the 92-ton 990F excavator which comes with a heavy-duty construction and optimised crushing design.
