  • Patent number: 9255363
    Abstract: 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”).
