The invention relates to an underground machine comprising: an undercarriage which comprises a rail-mounted travel unit; an upper carriage mounted on the undercarriage so as to be able to rotate about a vertical axis of rotation; a leader having a linear guide along which a sliding work carriage having a construction device is slidably mounted; and a coupling mechanism by means of which the leader is adjustably mounted on the upper carriage. According to the invention, the coupling mechanism has a telescopic arm by means of which a distance of the leader from the upper carriage can be adjusted.
The invention relates to a points transport vehicle (10) comprising at least one loading platform (18) for receiving a load (20), which platform is piviotable into a transport position (10) and a loading position (10') about a pivot axis (23) extending in the longitudinal direction of the vehicle, comprising at least one elongate support element (24) for fixing the load (20) to the loading platform (18), and comprising a first holding element (26), which is designed to rest on the load (20), a second holding element (28) being provided on the support element (24) and being designed to rest on the load (20), and at least one of the two holding elements (26, 28) being displaceable on the support element (24) in relation to the other holding element (26, 28) in order to releasably fix the load (20) on the support element (24) between the first and the second holding element (26, 28).
The invention relates to a device for loading and unloading a track, in particular a switch part, comprising an elongate traverse (12), which has a crane-hook holding apparatus (20), and at least two cross arms (30), which are provided on the traverse and extend transversely to the longitudinal axis of the traverse, wherein the cross arms (30) each have at least two holding elements (44) for the track, wherein at least one of the cross arms (30) is held in such a way that said cross arm can be moved along the longitudinal axis of the traverse (12).
The invention relates to a railway switch transport car, comprising at least one loading platform for accommodating freight, which loading platform can be pivoted about a pivot axis extending in a longitudinal car direction into a transport position and into a loading position, and at least one elongated load retaining device for fixing the freight on the loading platform. The load retaining device has a retaining element at one end, which retaining element interacts with the freight detachably and in a form-closed manner in order to fix the freight. The railway switch transport car is characterized in that the load retaining device is attached to the loading platform at the other end of the load retaining device, in such a way that the load retaining device can be pivoted about a pivot axis extending in the longitudinal car direction and can be displaced in a direction perpendicular to the pivot axis, a fixation direction.
