Recently，Sichuan Transportation Science and Technology Innovation Conference held in Chengdu，At the meeting, Liugong and Shudao Group jointly developed the first domestic charging and replacement highly integrated power battery assembly.（Hereinafter referred to as：Change the electric loader）、Char and replacing integrate electric loader and electric excavator（Hereinafter referred to as：Change the electric excavator）And other high-level innovative achievements.。

At present，Engineer Liu changed the electric loader、The electric excavator has been used in Yijin along the Yangtze River.、Ning Pan、It is applied in 7 expressway construction projects such as Luyong and Hanbanan Railway Construction Project.，In response“Double Carbon”Contributing to Strategic Objectives。

Compared to pure electric drive loaders，The advantage of changing the power loader is the length of time to change the battery.，In addition，Electric loader can also effectively solve the problem that charging piles can not be installed in some working conditions.。

For high dust in tunnel、Humid environment，And water gushing、Gas、Uncontrollable factors such as rock burst，The construction of construction machinery in the tunnel is more difficult.，Charging piles can not be installed into the hole.，Liugong Electric Excavator Does Not Need Charging Pile，High efficiency power exchange and other advantages，Become a sharp weapon for tunnel construction。

Change the electric loader、The power-changing excavator can flexibly separate the vehicle from the electricity，Provide more choices for customers，For example, flexible assembly and configuration of batteries、Buy the whole car, rent the battery, etc.。At the same time，Power exchange loaders and power exchange excavators can charge the replaced batteries centrally and control them uniformly.，It not only improves the safety of equipment, but also improves the life cycle value of power batteries.。

With the acceleration of the electrification process of construction machinery,，Engineer Liu Keenly Captures Market Demand，Expand the research and development of power exchange products，Actively promote the high-quality development of new energy industry for power exchange，Open a new era of power exchange。
