Background

The project involves the construction of an underground parking garage in an urban area. The site load mainly includes four 70 kW piling rigs and four 12 kW welding machines, with noticeable load fluctuations during operation.Due to limited grid capacity, diesel generators are used to support power supply, resulting in low efficiency and increased fuel consumption.

• Load condition：4 × pile driver 70KW + 4 × electric welding machine 12KW

 

Solution

1 × PowerCat-YD250P + Sync generator 320kVA

This integration ensures a stable, uninterrupted power supply for the crane while significantly reducing fuel use, emissions—enabling greener, more efficient construction.
