The invention relates to equipment (3) for fastening and releasing a number of rail sleepers, wherewith a plurality of loosely positioned and juxtaposed sleepers are gripped by gripping claws, and wherewith the distance between adjacent sleepers can be increased so as to correspond to a sleeper spacing (a) appropriate for a rail bed section (B) and wherewith the sleepers (1a-1g) are released in such position so as to rest on a prepared railroad bed section (B). The equipment includes a frame structure (5) which is comprised of at least three parts (50, 51, 52), which can be brought to a retracted position for co-action with sleepers that are located close together, and can be brought to an extended or expanded position when the sleepers (1a-1g) shall be spaced further apart (a). The equipment also includes means (10) for spacing all sleepers (1a-1g) at a predetermined distance apart (a). |
