The invention relates to an arrangement (1) for bringing two securing or releasing devices (4, 4a) active between a railroad sleeper and a rail section to a sleeper/railroad section securing or releasing mode with the aid of a piston-cylinder device (5) whose piston movements can be transmitted through the medium of pivotal attachments (5c, 5d) to two legs (6, 6a) that are pivotal relative to one other through the medium of pivotal attachments to an intermediate part (7). The free ends (8, 8a) of the legs (6, 6a) carry mutually facing elements (9, 9a) which are moved so as to bring said two devices (4, 4a) simultaneously from a free position in which the rail section is firmly clamped to the sleeper or from a clamping position to a release position. The legs (6, 6a) are pivotally connected to each other by a parallel-movement strut (20). A first pivotal attachment (20a) of the parallel-movement strut (20) to one leg (6) is positioned closer to said elements (9) than the pivotal attachment (6') of the intermediate part (7) tosaid one leg (6). A second pivotal attachment (20b) of said parallel-movement strut (20) to a second leg (6a) is positioned further away from said elements (9a) than the pivotal attachment (6a') of the intermediate part (7) to said second leg (6a). |
