On November 2, 2024, at the substation site of Evergrande Coal Mine, Haizhou District, Fuxin City, Liaoning Province, the installation of a 4MW/4MWH emergency power storage module developed and produced by FGI faced installation problems.

The mining area has been under construction for a long time, and the substation space is small. There are 60,000-volt high-voltage inlet lines on the left side of the energy storage foundation, lightning rod and overhead lines blocking the 6000-volt outlet lines on the right side, private houses on the back side, and PCS booster integrated equipment obstructing the front. Due to the increase of heating load in winter, the adjacent main transformer sent electricity in advance, resulting in the failure of large conventional cranes to enter the field, and the original hoisting scheme was forced to overturn. Installation is imminent, can only urgently re-establish the lifting plan!

As the site project manager, Zhuanxun Zongxing under great psychological pressure, not chaos, the site emergency coordination of mine leaders and relevant responsible persons, rational and orderly development of new lifting plans, orderly arrangement of personnel mechanical layout, lifting machinery from the conventional large crane to large tonnage folding crane, innovative use of crane, excavator, forklift combination.

Outdoor minus ten degrees low temperature, Sun Zongxing tracking the whole hoisting program implementation, on the morning of November 2, the folding arm lifting truck, excavator, towing cooperation unloading transfer to the lifting point, November 3 noon 12:35, folding arm lifting and forklift cooperation, in the drone air without dead Angle monitoring, take a day and a half, will be 17.5 meters long, 2.6 meters wide, The 21.7 ton storage tank is in position!

The re-developed lifting scheme is in place two days earlier than the pre-estimated time, effectively saving mechanical labor costs and construction cycle, becoming a classic large-scale energy storage and difficult lifting case, and the whole process of video recording, to make lifting case sharing for the industry.
