The present invention embraces a manually operated arrangement (“A”) and a method, adaptable for a transfer along a longitudinal extension of a rail (1) and intended to be able to secure said rail to a subjacent crosstie (2) by a horizontal transfer of clips (3: 3a), included in fastening elements (4), and displaceably oriented in relation to a holder (5) included in the fastening element (4), where the holder (5, 5a) co-operates firmly with said crosstie (2). The respective one of said clips (3; 3a) is adapted to, by a movement, allow displacing the clips (3: 3a) horizontally for a clamping of the rail base (1c) in relation to the holder (5). An opposed first pair (6a, 6b) of a first lever-shaped means (6) is adapted to, via its lower end areas (6aa, 6ab) co-operate with the clips. For this purpose, the invention provides a means (20, 21, 23) lifting the crosstie (2) with holders (5) and clips (3) up to the rail base, which means is adapted adjustable in height (“D”).
Manually operated arrangement (“A”), adaptable for a transfer along a longitudinal extension of a rail (1), having a cross-section formed by an upper rail head (1a), a rail web (1b) and a lower rail base (1c) and intended to be able to secure said rail against and to a subjacent crosstie (2) by a horizontal transfer of clips (3:
Method for, in a manually operated arrangement (“A”), adaptable for a transfer along a longitudinal extension of a rail (1) and intended to be able to secure said rail against and to a subjacent crosstie (2) by a transfer of paired clips (3, 3a), included in fastening elements (4), and displaceably oriented along a holder (5) included in the fastening element (4), where the holder co-operates firmly with said crosstie (2), and where the respective one of said clips (3, 3a) is adapted to, by a movement, allow displacing the clips (3, 3a) for a clamping to said rail base (1c) along the respective holder (5), an opposed first pair of levers (6a, 6b) of a first lever-shaped means (6) being adapted to, via its lower end areas (6aa, 6ab), co-operate with each a clip (3, 3a) in order to activate their counter-directed, horizontal movements, said first lever-shaped means (6), with its first pair of levers (6a, 6b), being turnably arranged around middle turning shafts (7, 8), and where they, via their upper end areas (6ac, 6ad), are in a cooperation with an extensible or shortenable device (9), such as a hydraulic piston-cylinder assembly (10), in order to bring said upper end areas (6ac, 6ad) from each other in a securing movement of the clips (3, 3a), and where said arrangement has presented a means (20) lifting the crosstie with the holder and the clips (3, 3a) up to the rail base (1c), characterized in that said means (20, 21 ,23) lifting the crosstie to the rail base is, as concerns its height position, selected adjustable.
