SDLG unveils concept electric compact excavator at bauma China

2018-12-06

SDLG showcased the E660F-EX, a concept electric compact excavator, at bauma China 2018. The concept excavator is SDLG?s foray into electromobility and is not available commercially. The E660F-EX was among the 25 construction machine models that SDLG exhibited during the event.

?The E660F-EX is SDLG?s first machine to utilise electric motors,? said Wang Xiaohui, General Manager of SDLG Import and Export Company. ?The concept machine demonstrates SDLG?s dedication towards 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 cu m, 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.
