  • Patent number: 4591200
    Abstract: The present invention relates to a lifting wedge which is intended in particular for lifting a paper roll in the vertical position, and which is made up of a substantially cylindrical lifting wedge part (1) having the cross sectional shape of the core hollow of the paper roll, a lifting belt (2) fitted to the lifitng wedge, and friction surfacing (3). The lifting wedge accompanies during transport the roll to be lifted.Previously known lifting devices of this type consist of lifting belts which are passed around paper rolls in the vertical position. The assembling of the belts and fitting them around the rolls is relatively difficult.The lifting wedge part (1) according to the invention is divided in its longitudinal direction preferably into three wedge-shaped sections. The lifting belt (2) encircles that wedge section which has a larger cross sectional surface in its lower part, and forms a lifting loop above the wedge section.

  • Patent number: 4492399
    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.
