XCMG electric excavator makes global debut

Chinese manufacturer XCMG, in collaboration with Cummins, has designed and built a 3.5-t electric excavator to serve as a technology demonstrator. The machine made its debut earlier this year at the Conexpo exhibition in the US.

The new electric excavator is suitable for operating on work sites in densely populated towns and cities around the globe, surpassing stringent emissions requirements and keeping noise to a minimum while getting the job done.

Powered by Cummins BM5.7E battery modules, the excavator has 45 kWh of battery power. Each battery module is designed for very high shock and vibration capability to endure the harsh conditions of the construction environment. Precise matching between motor and hydraulic system creates an efficient, reliable and quiet drive system, making it ideal for use in urban and suburban construction.

On a single charge of less than six hours, the excavator is able to meet operational needs for a full eight-hour shift. It can be charged overnight, eliminating downtime and taking advantage of off-peak energy savings.

The excavator is now back in China where it will be used in a series of performance and customer tests conducted by Cummins and XCMG, to prove capability of the demonstrator and refine a robust solution for the market.

This project is part of Cummins’ and XCMG’s agreement to collaborate on research, development and integration of technologies across a wide range of product lines.
