Cellulose units are rectangular packages in which the cellulose is transported from the factory to its intended use. The pulp units may vary in size, but are typically about 2,000 kg in weight. The units have a flat surface. The unit contains a plurality of bales and is bound together to be held together by a bonding member rotating around the unit, such as a steel wire 15.

Currently, pulp units are loaded and transferred in ports or similar locations from a transport vehicle or intermediate storage to a ship's cargo space or vice versa using a port crane and a special lifting device attached to it. The hoisting device generally comprises an elongated run-out: ': 20 beams or the like and differently engaging gripping means. The lifting device has • · · V: several (eg 1-4) nail carts and is designed to move • ·: several pulp units at a time. The pulp units are moved by moving the hoist ··· ** above the pulp unit and lowering it so that the nail trolleys are in contact with the pulp • • • · • ** unit binding straps so that the nails in the gripping bodies are lifting • · · • · * · · · * 25 on opposite sides of wheels. When the nail trolley rests on the pulp unit, the pulp unit material is slightly compressed and when the nails are moved against each other, they go under the lifting straps. The pulp units can then be lifted up on their lifting straps and moved into the cargo hold or other desired location on the ship.

From U.S. Pat. No. 3,587,889, the subject of the present invention is known from the prior art. * ·· 1 Introduction to pulp unit lifting equipment. The lifting device includes a horizontal bar that • • · supports the nail carriages. Nail trolleys have a load-shielding structure when lowered onto the load in preparation for lifting.

There are several drawbacks to current pulp unit lifting equipment and its use. When the nail carriages are supported by chains or wires or the like, the nail carriages sometimes get out of control with respect to the frame beams, especially when they are moved from one place to another when empty. Current lifting equipment can advantageously be used to lift a group of four units and transfer them to the ship. There are difficulties with lifting more groups. In the hold of a ship, the groups of units should be interconnected and, at port loading, at least 100 mm should be allowed between the groups for transferring Group 10 by forklift. The whole group can be taken with a forklift if the group is separated by at least 100 mm from the following.

It is an object of the invention to provide a lifting device for pulp units which eliminates many of the drawbacks associated with existing lifting devices. In particular, it is an object of the invention to provide a lifting device for pulp units which allows both pulp unit groups to be lifted and these groups to be mated to one another and also to separate the required number of groups from each other.

The object of the invention is achieved by a pulp unit lifting device characterized by [* 20] as set forth in the claims.

In a preferred embodiment of the invention, horizontal beams lifting several groups of units at a time. * * * is one or more similar. Each horizontal beam consists of single nail carts, • • • · · * .. divided by rope size across the beam. The nail carriages are movable at least by unit groups • ♦ • · 25, whereby two or more unit groups can be placed both in a clearing row .. and groups a short distance apart.

The invention will now be explained in more detail with reference to the accompanying drawings, in which: • · ·

Figure 1 shows a lifting device according to the invention coming up to lift two unit • · • · ”* 30 groups obliquely viewed from the side.

Figure 2 shows a horizontal bar and nail carts from the side.

Figure 3 shows the side guide and the nail carriage seen from the end, section A - A.

Fig. 4 is an oblique view of a nail carriage.

Fig. 1 shows a hanging hoisting frame 28 on a crane (not shown), to which, for example, three parallel horizontal beams 1 can be mounted to perform lifts simultaneously. Each horizontal beam 1 comprises nail carts 2 in a division determined by unit size placed in a horizontal beam 5. The most extreme nail carriages 2a, 2b include end plates 6, the position of which is preferably adjustable laterally with respect to the unit size relative to the nail carriage 2a, 2b. The end pads 6 are located lower than the lower part of the nail carriages 2. Two lateral guides 5 are attached to the horizontal beam 1, the purpose of which is to stop the swinging movement of the lifting device and to position the device on groups of units formed from the units 7.

10

Immediately below the horizontal beam 1 is a transfer bar 20 for the nail carriages 2. The transfer bar 20 is two-piece with its parts interconnected by a hydraulic cylinder 4. When the nail carriages 2 are slidably mounted on the horizontal beam 1 and mounted 15 at each point on the transfer bar 20, according to Fig. 1, the groups of four nail carriages can be moved towards each other and away by means of the cylinder 4.

The end plates 6 belonging to the most basic nail carriages 2a, 2b have several functions. First, the entire swinging of the lifting device can be stopped by lowering the lifting device to ground ':: 20 for a moment on the end-plates 6. Further, two or more groups of units can be squeezed into a single unit row by lowering the horizontal bar over 1 unit row, whereby the end plates are used to compress the unit row. The transfer rod 20 is driven by the cylindrical blades 4 to its longest position and, when pressed, the cylinder 4 is shorter.

In this way, two or more bale groups are formed into one long group and can be moved to the ship without the distance between groups x about 100-200 mm.

• · • · • · ·

When lifting the long group of units described above from the ship to the harbor, it may, if necessary, be subdivided into groups by moving the cylinder 4, moving the portions of the transfer bar 20, moving the necessary distance to the center of the unit. 30 rows to get two sets of units ready to land.

The attachment means 8 passes around the units 7, whereby the gripping means of the nail carriages engage the unit in a lifting position.

Fig. 2 shows the nail carriages 2 in the horizontal beam 1 having two pairs of claws 10, the pairs being spaced apart. Further, the nails 10 are spaced apart and convertible so that they, when lowered onto the unit, take the binding member from the surface of the unit between the nails.

Figure 2 also shows the attachment of the side guide 5 to the horizontal beam 1 via a housing 3 sliding on the horizontal beam. The side guide is secured to the transfer bar 20 under the horizontal beam 1 so that it moves sideways like the nail carriages when moving the transfer bar 20 10.

Figure 3 illustrates the adjustment of the distance position of the side guide 5 by means of a telescopically mounted attachment means by moving the arm 12 in the tube 16 and locking the arm into the tube through holes 15, e.g. with pins. The side guide 5 can be lowered by the cylinder 13 and the telescopic slide guide brackets 14 to remove the support from the unit row and is not a raised barrier when the unit load is lowered adjacent to the second unit row. The guide 5 is pivotally secured to the arm 12 by means of a joint 29, whereby, when it is lowered, it is pivotable and retracts due to its design. The lateral guide structure is connected via fastening plates 17 (Fig. 2) to the structure 3 sliding on the horizontal beam 1 20 and also to the transfer bar 20.

Figure 4 shows in more detail the structure of the gripping members 10, 19. When calculating the nail carriage j: *; 2 on unit 7, each gripping member 19 is capable of individually retracting upwardly from spring 11 and: "*: against its own weight. This ensures operation and operation of the gripping members j on the uneven surface of the unit, particularly in large unit rows e.g. · • ,, .: units in a row and one horizontal beam with nail carriages are lowered over them, in which case also the nail 10 at the lower end of each gripping member 19 should be on the surface of the unit.

When the nail carts 2 are on the units, the unit binding members 8 are located between the gripping members *: * ·: 10, 19 on the surface of the units. The gripping members 10, 19 are moved close to one another,. . ·. wherein at least the nail portions 10 overlap. The arms 19 of the engaging members are provided with horizontal bars · · · · · · · · · · · · · · · · · · · · · · · · kit kit 24 24, which can be moved inside the tubes 23 to adjust the distance The adjustment is locked either by a bolt or by a pin in the hole.

In the pair of gripping members, the arms 19 are pulled together and the securing means secured to the nails 10 are made by means of a hydraulic cylinder located inside the body 27 of the nail carriage. The hydraulic cylinder pulls the horizontal tubes 23 on both sides of the structure closer to each other, almost closed. The gripping member assembly is thus completely narrowed inside the body 27 by two horizontal axes 18 as the lugs 26 slide towards each other on said axes. The lugs 26 are attached to the horizontal tubes 23.

In connection with the gripping arms 19, the deliberately shaped plate arms 9 are connected by means of a joint to the upper end of the arms 19. Their free-turning, more than that of Fig. 4, is limited by stops. Instead, upwards, they may retract by rotating about their anchorage points. The function of these plate arms 9 is to ensure that the tie member 8 is detached from the nail 10 almost as soon as the arms 19 and nails 10 are spaced apart. This ensures that the binding member stays approximately in the center of the unit to facilitate any subsequent lifting.

20 The body of the nail carriage 2 comprises sliding surfaces 21 in contact with the horizontal beam 1, having a housing 30 thereon and a stiffener 25 of the housing. The nail carriage 2 is secured to the transfer bar 20 via the fasteners 22. The fasteners 22 and the transfer rod 20 have a plurality of optional holes for adjusting the distance between the nail carriages according to unit size.
