Abstract
A suspended coupling for lifting devices, particularly for picking up and depositing thermal insulation hoods from and over wire coils, includes a crossbeam to each end of which is connected a double-armed lever pair in an articulated manner and in a mirror-inverted manner relative to each other, wherein one lever arm pair is connected above the crossbeam through connecting rods to the lifting device, and wherein the other lever arm pair has hook-shaped ends underneath the crossbeam, wherein the hook-shaped ends can be coupled to support projections arranged on the upper side of the thermal insulation hood after the hook-shaped ends have been pivoted toward each other by a pulling movement transmitted to the lever pair by the lifting movement of the connecting rods. Arranged on the crossbeam and the upper lever arm pair are oppositely located pull-type electromagnets and corresponding armatures, wherein, in the switched-on pulling position, the electromagnets and armatures lock the upper lever arm pair against pivoting relative to the crossbeam and hold the hook-shaped ends of the lower lever.
