FIELD OF THE INVENTION This invention relates to material handling equipment, in particular to load handling devices.

The aim of the invention is to improve ease of use.

Fig. 1 schematically shows a load gripping device with open gripping arms; figure 2 - load gripping device located on the load; in FIG. 3 - load gripping device with a captured load; Fig. 3 is a load gripping device at the time of unloading.

The load gripping device comprises a traverse 1, a supporting element 2, a vertical guide 3, a flag 4 rigidly fixed on the supporting element 2, a control frame 5, gripping levers 6 hinged on the supporting element 2, articulated rods 7 connecting them to the frame 5 a swinging hook 8 with an emphasis 9 and a two-arm lever 10 with a counterweight 11 at one end to contact the emphasis 9.

The device operates as follows.

When the device is supplied to the load, the vertical guide 3 is connected with the crossarm 1, and the control frame 5 is in its lowest position. After the device is installed on the load, the crosshead 1 is lowered until it rests on the supporting element 2. In this case, the swinging hook 8 with the two-arm lever 10 passes by the flag 4 with some clearance A. In the lowermost position, the swinging hook 8 grabs the control frame 5, deviating at the same time by a certain distance B. greater than the gap A. After this, the yoke I is lifted, which, with a swinging hook 8, raises the control frame 5 by the engagement member 12, turning the gripping levers 6 through the hinge rods 7, and produces in this way the seizure of cargo. Passing by the flag 4, the two-arm lever 10 is deflected freely to its original position under its own weight. After setting the load to the desired location, the crosshead 1 is lowered until it lies on the supporting element 2. When moving down the two-arm lever 10, lying on the flag

4 rotates the swinging hook 8 using the stop 9, releasing the control frame 5, which remains in the lower position during the subsequent movement of the yoke

1 up. Remaining in the lower position, the control frame 5 by means of t 7 holds the gripping levers 6 in the open position. After lifting the drive beam 1, and with it the entire device, it

carried over to the next load.

SUMMARY OF THE INVENTION A load gripping device comprising a carrier, a vertical guide fixed thereon, articulated arms pivotally mounted to the carrier transversely to it, articulated rods fixed with lower ends on the upper arms of the gripper arms, a movable member on which the upper ends of the , a traverse movable along a vertical guide, and a mechanism for fixing the positions of the gripping levers, including articulated a hook fixed in the central part of the yoke, facing the vertical axis of symmetry of the supporting element by the throat, a rotary element fixed thereon and a hook engaging member the fact that, in order to improve ease of use, the movable body is a frame located in a horizontal plane longitudinally to the bearing element and the traverse with the ability to move along the vertical guide of the bearing element, the hook engaging element is rigidly fixed to the frame in its central part and made with an end bent to the hook pharynx, the rotary element is made in the form of a two-shouldered lever with an anti-weight on one shoulder, located horizontally in the upper part of the hook, while the device is equipped with focusing rigidly fixed to hook under the two-armed lever for contact with its counterweight fixedly secured on the support element and arranged vertically flag facing the outer side of the hook to cooperate with a second shoulder of a two-shouldered lever.
