Frame and crane for suspended-type hoists

Abstract

The invention relates to the lifting frame and crane of the suspended type lifting frame. In the crane of the invention, two cage-type girders are arranged alternately on either side of the lower longitudinal girder (310) in the longitudinal direction and the two cage-type girders can be detached or moved closer to the lower longitudinal girder (310) in the longitudinal direction through the cage-type assembly; two cage-type locking mechanisms (4) are both arranged on the lower lifting frame (3) and the two cage-type girders and the lower longitudinal girder (310) are locked in place by controlling the two cage-type locking mechanisms (4). The stability of the lifting, hanging and positioning processes of containers with the lower lifting frame (3) can be improved by controlling the cage-type locking mechanism and the structure of the lifting frame, which is more stable and safer than the current lifting frame.
