Overview
The eRG 21 T hybrid is a hybrid version of the RG 21 T telescopic-leader pile driver. A CAT C13 430 kW Stage V diesel is combined with an 88 kW electric motor and 125 A / 400 V CCR plug, allowing grid-supported operation and hybrid Power Management. The 26.8 m extended mast, 260 kN pull force and 150 kNm torque are retained, making it a direct emission-free alternative to the diesel RG 21 T.
