| Zusammenfassung: | The utility model provides a portal crane limiting device, wherein a rolling wheel is arranged at the bottom of each support leg of a portal crane, and the rolling wheel is arranged on a track. The portal crane limiting device comprises fixed members fixed on the side surfaces of the support legs of the portal crane towards an extending direction of the track, and a pair of limiting plates, wherein one ends of the pair of limiting plates are respectively detachably hinged with the fixed members through pin rolls to guarantee that the pair of limiting plates are respectively arranged at two sides of the track, friction blocks are respectively arranged at the other ends of the pair of limiting plates, wherein when the portal crane limiting device is used for limiting the portal crane, the friction blocks of the pair of limiting plates are in tight contact with the bottom surface of the track. The portal crane limiting device is simple in structure, small in volume and weight, convenient to operate, and capable of effectively limiting the portal crane, thereby being capable of preventing damage and safety accidents of the portal crane. |
