Midwinter is full of cold，Years old, cold and snowy。On the morning of December 18th，Jiangsu Changkuang Construction Machinery Co., Ltd. is located in Jiangsu Changzhou Jinchuang Rail Transit Industrial Park，A grand ceremony was held.New Energy Mining Machinery Offline and Global Product Launch。

This time, Jiangsu Changkuang released three new products.，It gathers the latest research results of new energy in Changkuang, Jiangsu Province.，They are respectively：

Pure electric off-highway wide-body dump truck - CKD108E：

CKD108EPure electric wide-body truck is a pure electric drive mining wide-body dump truck independently developed by Jiangsu Changkuang Mine.。The whole machine adopts a flexible frame structure.，Equipped with high-power motor、Three-speed transmission and double drive axle with large speed ratio。Vehicle length 9.9 meters，Width 3.65 meters，High 4.2 meters。The vehicle may be equipped with a front impact beam，Greatly improve vehicle safety。

Pure electric excavator - CKW520E：

CKW520EIt is a 52-ton pure electric drive excavator independently developed by Jiangsu Changkuang.，YesThe world's first 52-ton excavator with power exchange technology，It solves the difficulty of charging on the construction site technically.、Long charging time。

The whole machine adopts electric control hydraulic technology.，Independent development of EIC system、Vehicle control system and power exchange system，On the premise of ensuring the performance of the whole machine，More energy saving and environmental protection、Quiet and comfortable、It is convenient to change electricity，Provide users with a good operating environment，Meanwhile, the operation cost is reduced and the construction convenience is improved.。

Pure electric heavy-duty loader - CKZ060E：

CKZ060EThe pure electric heavy-duty loader is based on the early mature products.，By matching the EIC system、Optimize the product structure、Improve machine performance and other methods to design and manufacture，With small turning radius、Powerful、Strong mobility、Low noise、Wide working condition range and the like.，EspeciallyThe use economy is far superior to the traditional diesel loader.。

The products released by Jiangsu Changkuang have advantages in technology.：

 

1、Low energy consumption：At the stage of product feasibility development，Energy consumption targets lower than industry benchmarks are identified，And then achieve the goal through various technical means.。For example, it is the first time to use axial flux motor with high power density to match large displacement oil pump in electric excavator.、Independently developed control program、Multi-channel sampling、Multiple working condition test，Resulting in a 4% reduction in energy consumption-8%The goal of。

2、Innovative structural design：Take the electric excavator as an example.，It can not be fully promoted due to the problem of endurance mileage.，The technical route of power exchange has also been discussed by various manufacturers.，However, it can not solve the problem of excessive investment in power exchange.、Inconvenient power exchange and the like.，Changkuang professional team goes deep into the mining area，Understand customer usage requirements，The scheme of power exchange for forklift is put forward.，After testing，The power exchange process of the forklift shall not exceed 10 minutes.。

3、Large-scale：Large-scale products are characterized by high technology content.，The research and development cycle is long、The product value is high，Companies from large mining cards、Start with a large excavator，By introduction、Digestion、 Absorption 、Innovation，Eventually, the company will form a large construction machinery with competitive advantages.。

 

“Committed to global mine zero carbon smart operation”It is the theme of this conference.，It is also the enterprise mission of Jiangsu Changkuang.，As an old state-owned enterprise of mining machinery, it set out again after its renewal.，We look forward to it，Jiangsu Changkuang will one day become the focus of the field of mining machinery；We also believe，China and even the world's large and small mines.，You can see the equipment of Changkuang in Jiangsu.，It will become a pioneer in the optimization and upgrading of China's construction machinery industry.、Become a member of promoting the vigorous development of the construction machinery industry！
