A damping device includes a damper provided to an outer end of a stacker crane in a traveling direction. The damper includes: a rod member extending along the traveling direction; a first biasing member configured to bias the rod member outward in the traveling direction; and a movement restriction mechanism configured to allow inward movement of the rod member in the traveling direction and restrict outward movement of the rod member in the traveling direction when the rod member has moved inward in the traveling direction.

A coupling support for a central buffer coupling of a rail vehicle includes first and second holding plates to be secured to the body of the rail vehicle. The coupling support has a base plate and a transverse bar disposed between the holding plates. The transverse bar is resiliently coupled to the base plate and is disposed above the base plate. First and second pivot levers are disposed on the base plate such that the pivot location of each pivot lever is disposed below the transverse bar, and the pivot locations are connected to the base plate. Each upper portion of the pivot levers is connected to the transverse bar by an articulated connection such that a movement of the transverse bar away from the base plate is restricted by the articulated connections and a movement of the transverse bar towards the base is allowed by the articulated connections.

The present invention relates to a piston rod end for absorbing forces on a linear actuator in a train coupler, the piston rod end comprising a housing (2) enclosing a cavity (23) with a bottom surface (24), the cavity (23) extending in a longitudinal direction in the housing (2), an elongated insert (3) arranged at least partly inside the cavity (23) of the first portion (P), a spring (5) arranged inside the cavity (23), and a fastening device (4) comprising a transversal element (41) and a longitudinal slot (42) forming a play, one being arranged in the housing and the other in the insert, and configured to cooperate in such a way that the transversal element extends into the slot in a transversal direction in relation to the housing and is movable in the play. The invention also relates to a piston assembly and to a sealing method for sealing the piston rod end.
