LiuGong’s proven electric range of equipment is sparking interest in the Australian market
There’s been plenty of global fanfare about LiuGong’s wide range of electric equipment and several machines are already available in the Australian market, with strong interest from customers.
LiuGong was one of the first equipment companies to identify the potential of the battery electric vehicle (BEV) for the construction industry and has invested more than $100 million in research, development and machine testing over the past eight years.
There are nine product areas in total, from aerial access equipment to heavy-weight excavators and wheel loaders, and a sign of LiuGong’s confidence in the range is the company’s offering of five-year/10,000-hour warranties with the machines, which covers batteries, motors and controllers.
Impressive benefits
James Lipman, from the LiuGong distributor in Australia, says significantly reduced energy and maintenance costs compared with operating diesel machines, as well as reduced carbon emissions, was quickly attracting the interest
of numerous companies around the country.
“Companies can now buy a machine to help hit their corporate responsibility and sustainability targets, as well as their cost of ownership targets,” Lipman says.
“They recognise they can pay significantly less in cost over five years whilst still taking advantage of all the benefits.”
LiuGong data from more than 200 customer job sites has shown that BEVs reduce five-year operational costs by up to 70 per cent and maintenance costs by up to 50 per cent.
A mid-size wheel loader comparison indicated fuel and maintenance savings of $210,000 over five years, as well as emission savings of more than 330 tonnes, which was significantly more than the emissions produced by the diesel machine and, hence, would be available for offsetting other emissions.
A range of LiuGong electric machines are successfully operating in Australia, from mine sites in WA’s Pilbara region through to manufacturing plants in Victoria, including the 922FE excavator and wheel loaders at either end of the size spectrum, the 6.4-tonne 820TE and the 20.6-tonne 856HE.
The 922FE excavator’s large-capacity lithium iron phosphate battery can store 423kWh and the machine provides digging breakout force of 105kN. Its permanent magnet synchronous motor offers 165kW of power, equivalent to more than 220hp, and the excavator comes with a one cubic metre bucket.

The fully electronically-controlled hydraulic system on the 922FE excavator also provides pure electric drive for easy control.
Around the world, including in Australia, LiuGong says there are more than 6,000 electric wheel loaders currently operating in the field.
The small 60kW 820TE offers an extremely quiet, energy-saving and environmentally friendly solution. It can store 70.5kWh and caters up to a two-tonne load in its 1.2 cubic metre bucket, while operators can easily adjust the traction force and vehicle driving speed.
The bigger 856HE steps up the load capacity to 5.8 tonnes with a 3.5 cubic metre bucket.
Worldwide testing with the 856HE demonstrates that it can work up to 14 hours before requiring recharge – proving more than adequate for customer needs.
Lipman says the electric transmissions improve transmission efficiency and reduce noise for smooth shifting, while operators also enjoy a significantly higher comfort level in the machines compared with a constantly running diesel engine.
Electric power delivers a quieter operating environment with reduced vibrations, creating a less stressful working atmosphere for operators. The elimination of exhaust fumes also improves overall air quality, enhancing operator health and wellbeing.
Victorian trial
Holcim, a global building material supplier, has commenced a strong relationship with LiuGong Australia for its electric machines after initially trialling an electric wheel loader in Victoria. Its Australian operations include quarries, batching plants, manufacturing and corporate offices.
Holcim operations manager for Gippsland East Michael (Mick) Radford says the company is committed to decarbonising its operations on the journey towards net-zero emissions.
“The use of zero-emission vehicles like the LiuGong wheel loader aligns with our roadmap, bringing us closer to achieving our goals,” he says.
And there were other features of the 856HE that impressed.
“It performed better than we all expected,” Radford says.
“The loader could work long hours between charges and could keep up with the production, which meant it didn’t have to stop in the middle of the day to charge up. That means the charging time is less, so the cost is less.
“Electric machines, unlike diesel, also only need to be serviced every thousand hours, so the maintenance cost is much lower. And you haven’t got things like oil filter changes and labour time to worry about.”
Radford was also pleased with the design that enables hydraulics to be programmed via software to make them harsher or softer.
“This means we can make adjustments like the speed of the machine,” he says.
Radford was also particularly pleased with the service aspect of LiuGong.
“When we first bought the LiuGong equipment, the team spent a lot of time with us, checking that all was good and coping with any problems that arose,” he says.
“After a couple of months, you’d think that this level of service would fade away, but not so, I’d still be getting phone calls every couple of weeks checking on any issues. The level of support is outstanding.”
