Description

one

The invention relates to lifting devices and can be used for slinging and turning, for example, sheet and long products.

The chain of the invention is the expansion of operational capabilities by providing slinging of cargo for low-protruding elements.

FIG. 1 shows the proposed grip in the sling load position; in fig. 2 - the same, in the open position; in fig. 3 - the same, in the position of turning of sheet parts.

The gripper contains a bracket 1, on which the clamping lever 2 is hinged. One lever of the lever 2 is connected with the drive of its rotation, consisting of the rod 3, hingedly connected with the lever 2 and the cross-bar 4. The ha 3 has a protrusion 5 interacting with an eccentric , the latch 6. Between the shank of the latch 6 and the protrusion 5 installed spring 7. The second shoulder of the lever 2 is made in the form of a cam. The stop 8 for the retainer 6 is at the same time the axis connecting the two halves of the strap 1, which form the shed of the strap. Inside the pharynx, on the bracket, with an opal end, a clamping bar 9 is pivotally mounted with the possibility of ending

tact with the cam lever 2 and turning in the / plane of the bracket 1.

Expansion of operational capabilities by providing slings of cargo for low-protruding elements is ensured by the fact that the bar 9 is hingedly mounted on a bracket inside the grip of the grip with one end with the possibility of turning in the plane

10 staples.

Capture works as follows. Hook mounted on the hook of the crane with the help of the yoke 4, the gripper in the free position is set on the protruding 5 th part of the load to be gripped. In this case, the retainer 6 is preliminarily turned down as far as it will go into the protrusion 5. When interacting with the protrusions 5 tons and 3, an open position of the cam of the lever 2 is provided. The spring 7 fixes the specified position. During the subsequent slinging of the load, the retainer 6 is turned upwards against the stop, while the ha 3 under the action of the spring 7 moves upward, unfolding the cam of the lever 2 connected to it up to the stop in the middle part of the pressure bar 9. Thus, the pressure bar 9 is clamped

30 to the protruding part of the captured cargo. When lifting the grip by the crane, the cam of the lever 2 clamps the load through the clamping bar 9.
