Abstract
Abstract The invention relates to a lifting harness for lifting of a load comprising two or more essentially cylindrical objects (1), e.g. rolls of paper, which are in an upright position. The lifting harness is formed by two lifting slings (3), the ends of which are fashioned into eyes (4), and two endless lifting loops (5), each of which is joined to a different one of the lifting slings (3) and threaded through the eyes (4) of the other lifting sling (3). The lifting slings (3) are applied around the load (1) from opposite sides so that the lifting loops (5) extend above the load and this section of the lifting loops is attached to a lifting hook (2). On lifting, the lifting slings (3) are tightened around the load. According to one form of embodiment of the invention one of the lifting slings together with its associated lifting loop is replaced by a combined lifting sling-lifting loop which passes through the eyes in the other lifting sling and thence extends upwards to the lifting hook. The other lifting sling does not have any associated lifting loop. According to a further form of embodiment the harness consists of two combined lifting slings-lifting loops, each part consitituting a lifting sling with an eye in one end from which sling extends around one roll or paper and passes through the eye of the other sling, which is itself arranged in similar fashion, and thence extends upwards to the lifting hook, forming a hook loop together with the other part. According to yet another form of embodiment the lifting loops joined to the lifting slings are replaced by one or two separate lifting loops (5) which pass through all four eyes (4) in the ends of the lifting slings (3) and thence extend upwards to the lifting hook (2) forming a hook loop. the lifting loops pass through the region between the two rolls of paper on their way from one eye to the next eye and thereby produce a tightening of the lifting slings.
