Abstract

A cable guide for the trolley traveling winch on gantry cranes for container, general-cargo, and grab operation, with a land-side support and a water-side jib that can be tilted up, the necessary deflection rollers, tensioning devices, and at least one cable drum for the trolley traveling winch. In the cable guide for moving the trolley (8), all the cables (3a, 3b) and (6a, 6b) are led from the drive drum (13) to the land-side support end and are deflected there in the deflection rollers (7a, 7b, 7c, 7d) of the tensioning device (12a, 12b). One cable pair (3a, 3b) extends to the land-side cable connection (8a, 8b) of the trolley, and the second cable pair (6a, 6b) is led to the water-side jib end (5a, 5b), and is led to the water-side cable connection (8c, 8d) of the trolley after deflection by 180.degree. . Since both cable pairs (3, 6) extend at equal cable height (9) from the top edges of the jib (1) and the support (2) of the jib (1), only a simple deflection (14a-14d) and a low cable tension path are required for deflecting the cable at the fulcrum point (11) of the jib (1) during the retraction or erection.
