LIFTING DEVICE AND METHODThe present invention relates to a lifting device and method.BACKGROUNDIndustrial lifting (or hoisting) operations, and in particular heavy lifting operations, often carry risks, such as risks of damage to the lifted object and/or the surroundings, and risk of injury to personnel involved in the work operation. In relation to the latter, ever-tightening health and safety regulations are being imposed by various authorities to minimize such risks. One example, from the maritime industry, is the Safety of Life at Sea (SOLAS) Convention of the International Maritime Organization (IMO). A variety of other industries have similar requirements and regulations concerning lifting equipment and lifting operations.A particular risk associated with lifting operations is that manual intervention is required to attach the hoisting line, such as a crane wire with a hook, to the object being lifted, which may, for example, be cargo, industrial equipment, or another item. This often requires personnel in the vicinity of the lifted object, who will attach, for example, a crane hook to lifting slings attached to the object. This person may be at risk when the lifting starts, for example from unforeseen movement of the lifted object or errors made by the crane operator. Both for this reason and in order to minimize personnel cost, it is desirable to develop systems and methods which minimize manual involvement during lifting operations.Documents which can be useful for understanding the background include WO 2006/016851 A, FR 2744712 A, CN 201713206 U, US 3109677 A, US 4518186 A, and CN 102992147 B.The present invention has the objective to provide a lifting device and method which provide advantages over known solutions and techniques in relation to safety, operational efficiency, and/or other aspects. SUMMARYIn an embodiment, there is provided a connection arrangement for a lifting device, the connection arrangement comprising a first part and a second part, the first part being configured for connection to a lifting sling and the second part being configured for connection to a cargo. The second part comprises a ring element having a slot, and where the second part is configured to receive the first part such that a first load surface on the first part engages a second load surface on the second part. The connection arrangement may, for example, be used for lifting various types of cargo or equipment in industrial applications.In an embodiment, a first positioning surface is arranged circumferentially around the first part and configured to engage a second positioning surface of the second part.In an embodiment, a diameter of the first positioning surface is larger than a width of the slot.In an embodiment, the first part or the second part comprises a guide surface configured to guide the first load surface into engagement with the second load surface.In an embodiment, the first part has a cavity extending through it, with an upper and a lower opening, to receive and secure the lifting sling to the first part.In an embodiment, the second part comprises a collar configured for supporting the second part on a surface. The collar may have a semi-circular shape and be concentric with the ring element.In an embodiment, the first part has an upper end and a lower end, and the first part has an increasing cross-section between the upper end and the lower end. The first part may be substantially conical or funnel shaped. In an embodiment, the second part comprises lugs for connection to a cargo sling. The lugs may be connected to a plurality of cargo slings and at least one of the cargo slings may comprise a stiffening element.In an embodiment, a hinged one-way stopper is positioned across the slot.In an embodiment, at least one locking element is arranged on the first part or the second part, the locking element configured for securing the first part in an interlocked position with the second part.In an embodiment, the second part comprises a wire guide extending outwardly from the second part and arranged to guide the wire into the slot.BRIEF DESCRIPTION OF THE DRAWINGSIllustrative embodiments of the present invention will now be described with reference to the appended drawings, in which:Figure 1 is a perspective view of a first part and a second part of a first embodiment of a connection arrangement, assembled together.Figure 2 is a side view of a first part of a connection arrangement of a first embodiment.Figure 3 is a top view of a second part of a connection arrangement of a first embodiment.Figure 4 is a perspective view of a second part of a connection arrangement of a first embodiment.Figure 5 is a perspective view of a cargo with a connection arrangement of a second embodiment, where the first part is about to be positioned in the second part, before lifting has commenced.Figure 6 is a perspective view of a cargo with a connection arrangement of a second embodiment, where the first part is positioned in the second part for lifting.

The illustrative embodiments described here may be used directly, or with only minor adaptations, in a wide range of other industries.In an embodiment, a connection arrangement 100 comprises two parts; a hook replacement part referred to as a first part 110, and a slotted ring referred to as a second part 120. The first part 110 is preferably connected to a lifting sling or wire 101 (see Figs 5 and 6) which is typically connected to a lifting crane or similar. The first part 110 typically replaces a traditional crane hook. The second part 120 is preferably connected to chain slings, or similar, connected to a cargo to be lifted. Alternatively, the second part 120 can be connected directly to the cargo. The second part 120 is thus a lifting point for the cargo. Figure 1 illustrates such a first part 110 and second part 120 in engagement with each other, figure 2 illustrates the first part 110, and figure 3 and 4 illustrate the second part 120 in different views.The first part 110 preferably has a shape which is axially symmetric, i.e. it preferably has the outer shape of a profile which is revolved about a longitudinal axis, as can be seen from figure 1 and 2. Even though the first part 110 need not have such an axially symmetric outer shape, it could ease the positioning of the first part 110 into the second part 120 because it is not dependent of having one preferred position relative to the second part 120. A lower end 112 of the first part 110 comprises a flange or protruding portion 111. The protruding portion 111 provides a load surface 113 constructed to hold the cargo weight. The load surface 113 is configured to engage a corresponding load surface 123 of the second part 120. The load surface 113 is in the illustrated embodiment a horizontal surface, but it could also be angled, slightly curved, conical, etc.The second part 120 has a corresponding load surface 123, illustrated in figure 4. When the first part 110 is in engagement with the second part 120, as illustrated in figure 1, the two load surfaces 113, 123 are configured to meet. The shape of the load surface 123 of the second part 120 should be complementary to the load surface 113 of the first part 110, in order to provide sufficient contact between the two parts 110, 120.To ensure that the first part 110 is properly positioned on the second part 120, the first part 110 can be provided with a positioning surface 114. In this embodiment, the positioning surface 114 is a surface on the outside of the first part 110. The second part 120 could also be provided with a corresponding positioning surface 124. In this embodiment, the positioning surface 124 is a surface on the inside of the second part 120. The positioning surface 114 of the first part 110 is provided to engage the positioning surface 124 of the second part 120, and such provide sideways support in the engaged position. The positioning surfaces 114, 124 can also provide a centric positioning of the first part 110 on the second part 120. In the illustrated embodiment, the positioning surface 114 is extending upwards from the protruding portion 111. The positioning surface 114 is preferably cylindrical, but could also be conical, in order to ease entering of the first part 110 onto the second part 120.A conical surface 115, illustrated in figure 2, can also act as a guiding means or guide surface for guiding the first part 110 into position on the second part 120. The guide surface may, alternatively or additionally, be arranged on the second part 120. In such an embodiment, the first part 110 may, for example, have a simple disc shape which is guided into place from below by a guide surface on the second part 120.An upper end 116 of the first part 110 preferably has a smaller diameter than the lower end 112. A smaller upper end 116 makes it easy to enter the first part 110 in the second part 120. The first part 110 has in the illustrated embodiment a funnel shaped outer surface 117 between the upper end 116 and the conical surface 115. This outer surface 117 could also be conical, or have another configuration. The outer surface 117 connects the upper end 116 with at least the conical surface 115, or the positioning surface 114. A smaller upper end 116 can make the first part 110 lighter near the top, and heavier on the lower end 112. A weight distribution where the lower end 112 is heavier than the upper end 116 will contribute to keep the first part 110 in an upright position when suspended on a lifting sling. It is advantageous to keep the first part 110 in an as upright (vertical) position as possible, as it will ease both connection and disconnection of the first part 110 to the second part 120.The first part 110 comprises a cavity with an opening at the lower end 112 and the upper end 116. The opening at the lower end 112 is preferably larger (has a larger diameter) than the opening of the upper end 116. The cavity could e.g. correspond to the outer shape of the first part. The cavity of the first part 110 could also be funnel shaped, conical, or similar. The opening at the upper end 116 is preferably dimensioned such that it allows a lifting sling, wire, etc. to be easily fed through the opening, while still providing support for the first part 110 on the lifting sling. If the cavity near the lower end 112 has a larger diameter, the lifting sling, wire etc. can easily be fastened, e.g. with a knot or by any other means known in the art, and be hidden within the first part 110. The first part 110 thus encompasses an end of the lifting sling.Both the first and second parts 110, 120 could be made from any material suited for the application, and typically steel or a steel alloy is preferred for heavy crane operations. If required, extra weight could be added to the lower end 112, and especially the protruding portion 111, in order to keep it upright and stable during connection and disconnection, as mentioned above.The second part 120 comprises a ring shaped element 121 with a slot 122. The ring element 121 comprises a load surface 123. The load surface 123 is provided to contact a corresponding load surface 113 of the first part 110, as previously described. The second part 120 preferably also comprises a positioning surface 124 provided to engage a corresponding positioning surface 114 of the first part, as previously described. The slot 122 is suitable for a lifting wire to be entered through. When the first part 110 is positioned in the second part 120, as illustrated in figure 1, the slot 122 prevents the first part 110 from disconnection from the second part 120 by a sideways (horizontal) movement. The slot 122 should therefore be smaller than the diameter of the positioning surface 124. The slot 122 should be sufficiently small to not allow any misalignment between the first part 110 and the second part 120 to occur.The second part 120 comprises lifting ears or lifting lugs 125. The lifting lugs 125 can be designed to hold the vertical load by a shackle, which may be rotated freely around the lifting lugs 125 in order to make the device flexible to cargo slings during connection and disconnection. The second part 120 can be equipped with any number of lifting lugs 125, however two or four are preferred. The second part 120 shown in figure 1, 3 and 4 comprises four lifting lugs 125. The shape and function of the lifting lugs 125 is known to a skilled person. The lifting lugs 125, regardless of the number, should be equally spaced apart on the ring element 121. In figure 3, the four lifting lugs 125 are shown equally distributed around the centre of the second part 120. An equal distribution of lifting lugs 125 on the second part 120 provides an equal distribution of forces from the second part 120 to the first part 110 during lifting, and keeps the connection arrangement 100 in balance.A skirt 126 is preferably provided on the underside of the second part 120. The skirt 126 protrudes downwards, and has the shape of a cut cylinder, i.e. the cylinder has an open side portion. The opening of the skirt 126 is preferably coincident with the slot 122. The skirt 126 preferably covers approx.180° of the second part 120, i.e. the opening of the skirt 126 corresponds to the diameter of the skirt 126.The lower part of the skirt 126 is in the illustrated embodiment bevelled, such that when the second part 120 is resting on a level surface, such as the top of a cargo, the second part 120 is both elevated and angled relative to the level surface. The bevel should be such that the tallest portion of the skirt 125 is towards the slot 122. As the ring element 121 is elevated and angled relative to a surface it is resting on, it is possible to guide the first part 110 horizontally through the slot 122 and into the second part 120. A part of the upper surface 117 of the first part 110 should be able to pass through the slot 122.The inner diameter of the skirt 126 should be equal to or greater than the outer diameter of the protruding portion 111 of the first part 110. When the first part 110 is positioned in the second part 120, the outer surface of the protruding portion 111 could thus act as a second positioning surface engaging with the inside of the skirt 126. The skirt 126 also structurally strengthens the second part 120.When lifting a cargo, the two first and second parts 110, 120 are connected, optionally without any manual work from an operator.For connection of the first part 110 to the second part 120, the main principle is that the first part 110 is lowered below the second part 120 and a lifting wire is then guided inside of the ring element 121 through the slot 122. Then, when hoisting the connection arrangement 100, the first part 110 will be guided inside the second part 120 by the lifting wire itself and the cargo can be lifted.Optionally, this operation can be done automatically by positioning the second part 120 in such a way that the slot 122 is accessible along the side of the cargo. The operator of the connection arrangement 100 lowers the first part on e.g. a deck to avoid horizontal and vertical movements of heavy parts relative to the cargo deck. The first part 110 rests on deck with enough slack on the wire to allow it to be guided along the cargo and enter the slot 122 of the second part 120.An operator of the connection arrangement 100 can pick up the slack wire and the first part 110 will enter inside the second part 120 and the cargo can be lifted up. The protruding portion 111 of the first part 110 now holds the load by the ring element 121 of the second part 120. The cargo is held by slings to the lifting lugs 125 of the second part 120.When disconnecting the first part 110 from the second part 120, the main principle is that after the cargo is put on deck, the connection arrangement 100 is still lowered until the cargo slings prevents the second part 120 from being lowered further, and the first part 110 and the lifting wire is guided out of the second part 120.If the connection arrangement 100 is moved sideways after the cargo is put on deck, it can be lowered to the side of the cargo, instead of landing on the cargo itself. When the cargo slings prevent the second part from moving further down the side of the cargo, the weight of the first part 110 will ensure that it continues to be lowered in an upright position, while the second part 120 is held back by the slings. When the first part 110 is free of the second part 120, the wire can be guided out of the ring element 121 either by swinging the first part 110 to automatically guide the wire out of the slot, or an operator can manually guide it free from the second part 120.Figure 5, 6 and 7 illustrate one way of connecting a second part 220 to a cargo 230. The second part 220 in this embodiment has only two lifting lugs 225. By using tubes 231 on the outside of the slings 232, or stiff rods instead of slings, the second part 220 can be guided to a preferred position where part of the second part 220 protrudes from the cargo 230, and the slot 222 is outside the cargo 230, as illustrated in figure 5.Two slings 232 connected to two corners on the same side of the cargo is fitted with stiff tubes/pipes 231 causing the connection arrangement 200 to be forced to drop to one side of the cargo 230. The length of the rods/pipes 231 is made to ensure the first part 210 can be freely released from the second part 220 and to position the second part 220 in a preferred position on the cargo.When the wire holding the first part 210 enters the second part 220, it is advantageous that the second part 220 can be aligned horizontally and not flipped upside down. To achieve a flexible second part 220 to freely rotate around one axis in the horizontal plane, the second part 220 can be modified to have two lifting lugs 225 instead of four.The weight of the second part 220 is higher on the closed half than on the slotted half, and this prevents the second part 220 from flipping upside down. To avoid the second part 220 from flipping over to a vertical position, stoppers 233 are mounted such that they rest on the slings 232 suited with tubes 231.Combined with the weight distribution described above, the second part 220 will be positioned horizontally after the cargo 230 has been disconnected and the cargo 230 will be ready to pick up without personnel involved.Figure 8 illustrates an alternative first part 310 and an alternative second part 320. The second part 320 comprises an extended edge 340. This edge 340 fits into a matching slot 341 in the first part 310. This edge 340 will increase the strength of the second part 320 without severe increase in size and weight.Figure 9 illustrates how a second part 420 alternatively can be further modified in order to secure a first part to the second part 420. Securing a cargo can be required in different applications by regulations and where vertical disturbance of the cargo can cause risk of the second part disconnecting from the first part. The cargo can be secured by a hinged one-way stopper 450 positioned across the slot 422 of the second part 420. Such a one-way stopper is commonly known in the art. The stopper 450 can, for example, be spring-loaded in the closed position, and will prevent the wire from accidentally leaving the second part 420 through the slot 422. The stopper 450 can be operated manually in order to remove the wire from the second part 420, or, for example, a remotely controlled operation can be used. Figure 10 illustrates an alternative way of securing a first part 510 on a second part 520. Mechanical one-way stoppers 560 are spring-loaded in such a way that the first part 510 can easily enter the second part 520 by compressing the spring 561 during an upwards motion of the first part 510 inside the second part 520. The one-way stoppers 560 will lock the first part 510 and the second part 520 together to prevent axial movement and unintended release.The spring 561 that secure the stoppers 560 in a locking position can be compressed manually by an operator or remotely, for example by use of electromagnets. An internal electric circuit could be driven by battery and the electromagnets could be triggered wirelessly, for instance by the crane operator. For this purpose, the first part 510 may have a wireless receiver 562 and actuators 563 capable of disengaging the stoppers 560 upon signal from an operator.Figure 11 shows an alternative embodiment, in which the mechanical one-way stoppers 560 are arranged on the second part 620 such as to prevent the first part 610 to move downwards and disengage when the first part 610 is positioned in the second part 620. The mechanical stoppers 560 may, as above, be spring loaded such that they are automatically pushed back as the first part 610 enters the second part 620, but then engage in the locking position.Figure 12 shows an embodiment where the second part 220 comprises a wire guide 234. The wire guide 234 extends outwardly from the second part 220 and is arranged to guide the wire 101 into the slot 222. The wire guide 234 thus assists the operator of the lifting arrangement to guide the wire 101 into the slot 222 and thus to position the first part 210 into the second part 220. The weight of the wire guide 234 may be designed to be small compared to the rest of the second part 220, in order to avoid an angled positioning of the second part 220 and misalignment when the first part 210 engages the second part 220.
