SDLG showcased a concept electric compact excavator - the E660F-EX - at the Bauma China 2018 expo that can perform continuous digging for about three hours on a full charge. The 6t 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.

The concept excavator is SDLG’s first foray into electromobility and is not available commercially.

Wang Xiaohui, general manager of SDLG Import and Export Company, said: “The E660F-EX is SDLG’s first machine to utilize electric motors. “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.”
