The 6 t capacity prototype emits zero emissions, reduces noise levels, and offers higher efficiency and significantly reduced operation costs.

SDLG showcased the E660F-EX, a concept electric compact excavator, at bauma China 2018. The concept excavator is SDLG’s first foray into electromobility and is not available commercially. The E660F-EX was among the 25 construction machine models that SDLG exhibited during the November 27 to 30 event at the Shanghai New International Expo Centre in Shanghai, China.
“The E660F-EX is SDLG’s first machine to utilize electric motors,” said Wang Xiaohui, general manager of SDLG Import and Export Company. “The concept machine demonstrates SDLG’s dedication toward electromobility. We are investing in research and construction equipment that will produce lower emissions, reduced noise levels, and will be more energy efficient without compromising machine performance.”

The 6 t capacity E660F-EX is based on the current E660FL compact excavator, which has a bucket capacity of 0.2 m³, maximum excavation force of 40 kN, and swing speed of 10 r/min. To make the machine electric, the combustion engine was replaced by a 30 kWh lithium battery and switched reluctance electric motor.
The concept E660F-EX can be recharged by plugging into a power grid or the vehicle-charging facilities that are already available in China. A full recharge takes between three to four hours on a 32 amp grid. With a dedicated grid, the E660F-EX could be recharged within one hour.
“On a full charge, the E660F-EX can perform continuous digging for about three hours,” Wang said.
In addition to the concept electric excavator, SDLG showcased a range of its construction equipment that demonstrates “reliability in action” during the four-day event:

• Wheel Loaders: L918F, L955Fc, L968F, L975F, L989F, L9120F
• Excavators: ER616F, ER636F, E655F, E675F, E6135F, E7150F, E6210F, E6300F, E6360F, E6460F LC
• Backhoe Loader: B877F
• Road Rollers: RD730, RS6260, RP6300
• Motor Graders: G9138, G9200, G9260

SDLG has an established dealer network in China, with skilled technicians that provide service and support functions throughout the country. SDLG is committed to becoming the world’s leading construction machinery brand. The company has established a global dealer network that covers more than 80 countries.
As the leading construction tradeshow in Asia, bauma China featured close to 3,000 exhibitors from 41 countries and attracted some 170,000 visitors from 149 countries.

“Bauma China was a great opportunity for SDLG to showcase our reliable construction equipment that helps to construct a quality future,” Wang said. “Looking ahead, SDLG will continue to develop and test electromobility products in different sizes as we work towards building a better future with our customers.”
