    A lifting wedge 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 lifting wedge, and friction surfacing (3). The lifting wedge accompanies during transport the roll to be lifted. …<??>The lifting wedge part (1) 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. When the lifting belt is tightened, the wedge section encircled by it presses against the outer wedge sections, whereupon the friction surfacing (3) on the circumference of the lifting wedge presses against the inner wall of the core hollow and causes the lifting wedge to adhere reliably to the core hollow. The lifting wedge can be of wood and sawn into wedge sections, or it can be cast into wedge-shaped sections. The friction surfacing is preferably in the form of a rubber belt, or it can be friction-increasing material on the surface of the wedge sections. Band or rope can be used for the lifting belt.

    The invention relates to a lifting and transport engineering.
    The purpose and the invention is to simplify the design.
    FIG. 1 shows the lifting wedge, general view; in fig. 2 - the same, bottom view; in fig. 3 - a piece of wood, used as a lifting fixing device, cut into wedge-shaped sections, general view; in fig. 4 - the same, bottom view; in fig. 5 - the same, top view.
    The lifting wedge comprises a cylindrical lifting part 1 made of wood, preferably of birch or plastic, and a cross section of the hollow central part of the product corresponding in cross section. Lift part 1 is divided into three wedge-shaped sections a, b, c (side a and c and middle b) with flat cuts converging in an upward direction. The middle section b has a larger area in its lower part than the side sections a and c. A lifting strap 2 is attached to and missed around the middle section L. A lifting strap 2, made, for example, of synthetic fiber tape, forms a loop over the front section for hanging onto a lifting mechanism. The side wedge-shaped sections a and c cover the sleeve 3 attached to one of them. The sleeve 3 is made with an external friction surface made of rubber. The lift portion should preferably be three times as long as its diameter, and the sleeve friction surface should be 3 / A of its length.
    Lifting belt 2 can be made of rope. In this case, the middle section b is made with a channel in which the rope is located.
    The lifting strap can also be made in the form of a loop passing through a hole formed in the middle section | C & C. Last attached to the bottom of the middle section.
    The lifting wedge is fixed in the hollow core of the lifted product D in a position in which the sections are displaced one with respect to the other and their circumference will be smaller. The lifting loop is attached to the hook of the lifting mechanism. When it is moved upwards, the belt is tightened, the sections are moved, pressing against the walls of the product and pressing the sleeve.
    The lifting wedge is removed using an auxiliary tool, the lower support part of which is inserted over the middle section.

    Invention Formula
    Lifting wedge for lifting the hollow product in a vertical position, comprising a cylindrical lifting part with a cross section corresponding to the cross section of the hollow central part of the product, divided into three wedge-shaped sections by flat cuts converging in the upward direction, the middle of which has a large section area in its lower part , a lifting belt attached to the middle section and passed around it to form a lifting loop above it, and means for holding the side wedge-shaped sections having a friction clutch In order to simplify the construction, the lifting belt is attached to the base of the middle section, and the means for holding the side wedge-shaped sections is a sleeve encompassing the sections and attached to one of the side sections, while the friction the surface is made on the outer surface of the sleeve.
