an elongated linear carriage guide comprising a first guide end and a second guide end at eithers ends of said elongated linear carriage guide,
a hammer carriage arranged to be displaceable back and forth along said elongated linear carriage guide,
a lifting line connected to said hammer carriage and to said hammer, wherein said hammer carriage is connected to said hammer by means of said lifting line so that said hammer is displaced in response to displacement of said hammer carriage, wherein said lifting line is extending from said hammer carriage in a direction towards said first guide end,
a displacement carriage arranged to be displaceable back and forth along said elongated linear carriage guide, wherein said hammer carriage is separate from said displacement carriage,
a displacer connected to said displacement carriage and arranged to displace said displacement carriage,
wherein said displacement carriage is arranged between said hammer carriage and said first guide end so that when said displacement carriage is displaced in a direction towards said second guide end by said displacer, said displacement carriage will make contact with said hammer carriage and thereby also force said hammer carriage in said direction towards said second guide end.
