CELLULAR LIFTING DEVICE

The present invention relates to a cellular bale hoisting apparatus comprising a horizontal frame bar which is removably attached to the crane and the system and to a nail trolley that is movably attached to the longitudinal axis of the cell and which is provided with means for grasping and moving them.

Cellulose bales are bale-shaped packages in which cellulose is transported to work sites. Cellulose bales may vary in size but are usually paint 2,000 kg. The bales are round and have flat ends. Cellulose bale protector) cardboard overlay. The attachment means is a lifting strap around the pulp bale, which may be e.g. a steel band.

15 Currently, cellulose bales are loaded and transferred in ports or similar from a position or interim storage facility to a ship's cargo space or vice versa using a special lifting device attached to Satai. The lifting device generally comprises a silicon beam or the like and the gripping elements disposed thereon with chains, wires or the like. The lifting device has a plurality of (e.g. 1-4) nail carriages and it is possible for the lifting device to move several pulp bales at one time.

After that, the pulp bale can be picked up by f ": a lifting strap and moved to the ship's cargo space or other desired location

US Patent No. 3,587,889 discloses the subject of the invention, the patent application of the patent. 4 - -. 4 4 1 11 2 sometimes in an unmanageable way with respect to the trunk beams of the country, and especially when it is empty from one place to another. Then you have to wait too much for loading! where ever before the nail carts can be lowered onto the surface of the pulp bales 5 onto the pulp bales. The nail carriages will always have some movement downwards and there is a risk that they will not hit the pulp exactly where they are, with the nails evenly on both sides of the lifting strap. Fuck the nails on the lifting strap and push the lifting device up again. These measures will slow down your work.

It is also a disadvantage that the nail mechanism can damage the pulp bales if the nail carriage does not press down sufficiently on the upper surface of the pulp bale so that k does not reach under the lifting strap or is not in position. When the nail carriages are mounted on the wires, the only heavy mass is the nail carriage itself and the siihc 15 and their weight.

An object of the invention is to provide a pulp bale lifting device which eliminates the drawbacks associated with lifting devices. In particular, it is an object of the invention to provide a t-bale lifting device which can be used to lift pulp bales quickly, securely and without breaking surfaces.

The object of the invention is achieved by a pulp bale lifting device, which is characterized by the * * »* · * as set forth in the claims.

In a pulp bale lifting device according to the invention, the nail carriages comprise ♦ · • · *** boom attachments which are fixed to the nail carriage. the trolleys are secured to the frame truss by booms, providing a structure that * # * and the nail trolleys cannot swing when moving and lowering the pulp ^ ·, 1 '

In a further preferred embodiment of the invention, claw-like members are attached which extend below the claw-like members. The roller wheels slide on and do not damage it when moving.

In a further preferred embodiment of the invention, the booms are fixedly connected to the frame beam and the booms are fixed to the mounting frame vertically. The mounting frame allows the booms and nail carriages to be secured to the frame truss both horizontally and vertically. In addition, the lift <10 preferably lies between the nail carriage body and the attachment body.

The invention will now be explained in more detail with reference to the accompanying drawings. Figures 1a and Ib show a lifting device according to the invention, viewed from the side and end 15 of the bales end 15,

Figures 2a and 2b show the lifting device according to Fig. 1 in a lifting-transfer position: viewed from the end,

Figures 3a and 3b show the lifting device in a lifting-transfer position from the side and the ends; Figures 4a and 4b show the lifting device according to Fig. 1 in a disengaged position from a view.

*: ***: The pulp bale transfer device shown in the figures includes crane 1 detached * * · *; * truss frame 2, nail trolleys 3 attached to it with gripping element · only the underside of the crane rotor is shown.

Nail carriages 3 include fastening bodies 9, booms 6 and pins 7 attached thereto, which are provided with gripping means 4. Fastening bodies 9 o are movable in the longitudinal direction of the frame beam 13, and the booms 6 are pivot 5 through the frame 9 and extend downwards thereto. Booms <on either side of the frame beam 13 and the nail carriage o secured to their lower end In this embodiment, the gripping members 4 are nail-like members extending from the center of the nail car body 6 to different sides extending from the body to the body. There are four arms and the said arms are in pairs facing each other, i.e. the device has two pairs of claws, the claw-like members being disposed so that they are approximately apart from the water. Therefore, they are not in the opposite position when in the closed position. To these claw-like members 4 are mounted roller wheels 8, which extend 15 below the members. The nail bodies 7 include a nail drive mechanism for adjusting the blades and wheels 15 which are hydraulically actuated.

The booms are fixed to the mounting frame 9 in a movable vertical position. Further included are spring means 10 disposed on the nail carriage body 7 and fastened: 20.
