0, the height of the packet being captured, the size of the protruding part of the pickups 12, the ratio of the shoulders of the diverter arms 9 and is constructive. To the horizontal part of the rods is attached with the ability

5 move the web 18 with the straps 19 to secure the second pair of suspension straps. In the lower part of the rods (additional inclined posts) there are installed pivoting stops 8 with clamps 20, made in the form of brackets, hooks, loops or pins in the eyes, and eyes 21 for pivotally attaching the diverter arms 9. The lower parts of the rods may have a connecting jumper .

5V top (horizontal) part

Rods 7 in the middle of the jumpers made a vertical hole 22, set the pivot latch 23 and the rod lock 24, made in the form of a pin in the eyelet. The location of the jumpers and the hole 22 corresponds to the equilibrium state of the device without a load in the position of its nodes in the period of approaching the package (see Fig. 1). Inside hole 22 is suspended from

5 ring 1 can be moved along the axis of the bore, rod 25. The length of the sling stem rod can be adjusted. At the end of the horizontal sections of the rods are installed plugs 26, which are placed with

0 possibility of limited movement additional axis 5. Instead of forks 26, a flexible element that performs the same functions can be used.

Frame 6 is made of two bolts with

5 holes at the ends for mounting the main 4 and additional 5 axes. The frame bolts may have a hard link.

The pivoting stops 8 are made in the form of figured plates with holes under the axis,

0 installed at the bottom of the rods 7.

The stop 8, when gripping and transporting the bag, rests against the lateral surface of the inclined posts of the rods 7 and the lugs 13.

5 The diverter arms 9 are made curved and have three holes for hinging to the lugs 14 of the catching lever 2, to the lugs of the rod stand 21, and also for installation in the middle part of the stop plates 10.

The device works as follows. The gripping device suspended by the ring 1 on the crane hook is brought to the package being captured and simultaneous horizontal movement and lowering of the winding tongs 12 under the shoulders of the ingots of the package and the stop 15 of the holding lever 3 over the side surface of the package. In this case (see Fig. 1), the gripping device is suspended from the hook of the load-lifting mechanism through the rod 25, which abuts the latch 23, is held in a predetermined position by suspension lines, secured in brackets 19, jumpers 18 rods 7, and the suspension lines, secured in brackets 17 holding The levers 3 are loosened and allow the lever 3 to change its position when the stop 15 is in contact with the top surface of the bag. By changing the length of the sling associated with the rod 25, you can adjust the specified position of the device without a load. The additional axis 5 rests on the lower part of the fork 26 and does not allow the frame 6 to rotate counterclockwise on the main axis 4. The pivoting stops 8 are fixed by the latches 20 in a position where the upper part abuts against the side surface of the additional posts of the rods 7 and this lower part in the lugs 13 of the pick-up lever 2, keep it in a predetermined position. The branch arms 9 are in a position in which the stop plates 10 do not protrude beyond the vertical plane passing through the surfaces of the uprights 11 of the pickup lever 2 facing the cargo and are not in contact with the side surface of the bag being gripped.

After inserting the load carrying lugs 12 under the shoulders of the ingots of the bag, the crane hook is lowered and horizontally moved. In this case, the gripping device lowers and rests with frame 6 on the packet to be captured, and rod 25 lowers and releases the latch 23 to rotate it clockwise. After turning the latch 23 and fixing it with the latch 24, the gripping device is raised. In this case (see Fig. 2), the rod 25 freely rises in the hole 22, and the stop 15 of the holding lever 3 and the hooks 12 of the lever 2 compress the bag diagonally over its ribs and securely catch it for further transportation. Then, the pivoting stops 8 and the latch 23 of the fixers 20 and 24, respectively, are released, and the bag is transported to the installation site. The necessary pressing force from the suspension straps is transmitted to lever 2.

through the pivoting stops 8 of the rods 7, resting against the lugs 13 of the lever 2, and the stops 15 - directly from the lever 3. Vertical position of the transported load

can be adjusted by moving the jumper 18 rod 7.

When lowering the hook of the lifting mechanism after installing the package, the rods 7 are rotated counterclockwise

0 on the axis 4 and the fixed stops 8 move away from the bosses 13, under the action of their own weight, rotate clockwise and get out of engagement with the bosses, allowing the rods 7 to move away from the relative lever 2. At the same time, the rod 25 is lowered into the hole 22, the unlocked latch 23 under the action of its own weight, rotates counterclockwise and blocks the output of the rod 25 from

0 hole 22 when lifting.

During the subsequent lifting of the hook of the lifting mechanism (see Fig. 3), the rod 25 rests on the latch 23 and lifts the gripping device. In this case, the rods 7 are rotated clockwise on axis 4, through the diverting levers 9, the thrust plates 10 are brought to the side surface of the bag and upon further movement through the diverting levers 9, the clamps 12 are pulled out from under the shoulders of the package's nose (see fig. 4), and the lever 3 rotates on the axis 5 clockwise, retracts the stop 15 from the bag. There is an automatic handling of cargo.

The gripper can be fed to the next grip of the next bag in the position shown in FIG. 3 without prior rotation of the rods 7 counterclockwise relative to the lever 2, rotation counterclockwise and

0 fixing stops 8 - with the implementation of these operations directly on the captured package.
