ABSTRACT:
A cylinder piece for a cylinder of a pile driving ram comprises inlet and outlet ports and at least two guide girdles for supporting guide members adapted to co-operate with a guide stay of a guide frame.
This considerable cylinder piece can be readily made in such a way that the possibility of unexpected damage is reduced and that it has a long lifetime, in that a core of the cylinder piece is made from ferritic-perlitic nodular cast iron with at least two substantially cylindrical guide girdle faces for guide girdles and in that at least two guide girdles are clamped around the guide girdle faces, which guide girdles are each mainly formed by a ring from predominantly ferritic nodular cast iron with a cylindrical bore.
