5-Year Total Cost Breakdown

The expected life of the Electric EBR-G Series is 5,000km and as it is highly durable, maintenance is not required for the first five years of use. Maintenance costs can also be significantly reduced compared to the Pneumatic STG Series.

Activity Status

The positioning time of the Pneumatic STG Series is shorter. However, as there is an upper limit to the allowable absorbed energy of the Pneumatic STG Series, the max. speed cannot be increased, and so there is no difference.
