ABSTRACT:
The invention relates to an improvement in a hook for lifting rollers, in particular a reeling drum hook. The object of the invention is to prevent the shaft of a roller from lodging on the tip of the hook. This is achieved by pivotally mounting a body on the tip of the hook, which body is formed as an extension of the tip and whereby a part of the body functions as a weight body.
