XCMG XG85-HEV Hybrid Hydraulic Diaphragm Wall GrabDeployed at a Yangtze River Delta rail transit hub, the new-energy power tackles 60-meter ultra-deep diaphragm walls, improving quality and reducing consumption, cutting carbon and boosting efficiency.

This hub station connects multiple urban rail transit lines, and the underground two-level island platform is supported by large-scale foundation pit works; the 60-meter ultra-deep diaphragm wall is a prerequisite key process for the project. The on-site strata are complex, with uneven soil hardness and alternating soft and hard layers,making deep trench excavation highly prone to jamming and trench profile deviation。

Coupled with increasingly strict environmental controls in urban areas, the compliance pressure from the high energy consumption and high emissions of fuel-powered equipment continues to rise. Considering technical adaptability and green construction requirements, the project department ultimately selected theXCMG XG85-HEV hybriddiaphragm wallhydraulic grabto undertake all trenching operations.

Based on its dedicated hybrid new-energy architecture, the equipment is suited to standard trench panel construction 2.8m wide, 1m thick and 60m deep; when facing hard soil layers, the equipment delivers stable power output, and trenching regularity remains controllable throughout.

The equipment offers two new-energy operating modes, plug-in and range-extended;in plug-in mode, power consumption is only 90-100 kWh per hour, saving 60% energy compared with conventional fuel equipment of the same class; in range-extended mode, it still achieves 42% energy savings，thereby reducing project operating costs at the source. In pure electric mode, operation produces no exhaust emissions and runs more quietly, perfectly meeting the mandatory green construction standards in urban areas.

The project construction manager highly praised the equipment's performance:

XCMG will continue to iteratenew-energy underground engineering equipment，usingenergy-saving and efficientproducts to supportthe green development of urban rail transit construction
