1. A ram assembly for use by a system for driving elongate members into the earth comprising an actuator rod assembly, the ram assembly comprising:
a top plate defining at least one clamp opening and at least one top plate lift opening;
a bottom plate defining at least one anchor opening;
a lift plate defining at least one lift plate ram cable opening;
at least one add plate defining at least one add plate ram cable opening; and
at least one ram wire rope assembly; wherein
the at least one add plate is arranged between the top plate and the bottom plate;
the at least one ram wire rope assembly extends through the at least one lift plate ram cable opening and the at least one add plate ram cable opening and between the at least one clamp opening and the at least one anchor opening to inhibit movement of the top plate, the bottom plate, the lift plate, and the at least one add plate relative to each other; and
the at least one top plate lift opening is sized and dimensioned to allow at least a portion of the actuator rod assembly to extend through the top plate; and
the lift plate is adapted to be secured relative to the actuator rod assembly.
