Abstract

A drive (1) for intermittent actuation of a drop hammer device in which a drop hammer (5) is capable of dropping, from a raised position to an impact position, upon actuation by an operator, the device allowing for a variable position, the drive (1) including: a drop hammer (5) restrained to move between the raised and impact position; an endless means operatively connected to a rotating drive, an upper end of the endless means engaging with an upper wheel (3); at least one engaging piece (4) fixed to the endless means; and a catch (7) releasably fastenable to a mounting fixture fixed to the drop hammer, the catch (7) engaging with the engaging piece (4) to raise the drop hammer (5) to the raised position, the catch (7) disengaging from the engaging piece (4) at the raised position as the engaging piece (4) travels around the upper wheel (3), to thereby drop the drop hammer (5), wherein two or more mounting fixtures are fixed to the drop hammer (5) at spaced positions for varying the height of the raised position.
