Rail vehicle with crane rails for portal cranes

摘要

The present invention includes a machine frame (2) supported on a rail traveling device (4), and the machine frame (2) includes a portal crane (drivable on both sides in the rail vehicle longitudinal direction (3)). 11) relates to a rail vehicle (1) in which a crane rail (8) is arranged. At this time, in order to lower or raise the portal crane (11), a part of the crane rail section (12) of each crane rail (8) is arranged so that its height can be adjusted by the drive unit (18). Thus, the portal crane (11) having a height higher than that of the prior art can be used without violating a predetermined vehicle limit at the time of transfer travel.
