Overview
The eRG 22 S hybrid mirrors the RG 22 S geometry but replaces the CAT C18 with a compact CAT C13 diesel plus on-board electric motor and CCR grid plug (125 A / 400 V AC). System power is 510 kW with hybrid Power Management, keeping the 400 kN sledge crowd force and 22.1 m pile length while enabling emission-free work under grid power.
