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), said arrangement 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, 3a) included in fastening elements (4), and displaceably oriented along holders (5, 5a) included in the fastening elements (4), where the holders (5, 5a) co-operate firmly with said crosstie (2), and where the respective one of said clips (3, 3a) is adapted to, by a movement from a detached position, allow displacing the clips (3, 3a) horizontally for a co-operation with the rail base (1c) in relation to the holders (5, 5a), an opposed first pair of levers (6a, 6b) of a first lever-shaped means (6) being adaptable to, via lower end areas (6aa, 6ab) of said first lever-shaped means, cooperate with each of said clips (3, 3a) in order to activate counter-directed, horizontal movements, said first lever-shaped means (6) with said first pair of levers (6a, 6b) being turnably arranged around middle horizontal turning shafts (7, 8), and where said first lever-shaped means (6), via upper end areas (6ac, 6ad), co-operate with a first extensible 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), said arrangement having a means (20) lifting the crosstie, with holders (5, 5a) and clips (3, 3a), up to the rail base (1c), wherein said lifting means provides an initial adjustment to a maximized height and said lifting means further comprises a second extensible device (21) having a variably adjustable end position, which at the maximized height is adapted to assume a fully brought together position.
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 lower end areas (6aa, 6ab) of said first lever-shaped means, co-operate with each a clip (3, 3a) in order to activate counter-directed, horizontal movements, said first lever-shaped means (6), with said first pair of levers (6a, 6b), being turnably arranged around middle turning shafts (7, 8), and where said first lever-shaped means, via upper end areas (6ac, 6ad), are in a cooperation with an extensible 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 a means (20) lifting the crosstie with the holders (5, 5a) and the clips (3, 3a) up to the rail base (1c), wherein said lifting means provides an initial adjustment to a maximized height and said lifting means further comprises a second extensible device (21) having a variably adjustable end position, which at the maximized height is adapted to assume a fully brought together position.
