case 4, springs 12 and 13, shoulder 14. Case 4 is introduced into the cavity of the load until it stops, lowering the yoke and moving the rod 7 to the lowest position, compress the spring 12. In this case, the sleeve 6, in contact with the sleeve 5, rotates. When the movement of the rod 7 upward wedge 9 unclenches

gripping cams 10, which capture the product. For release, the device from the load to the traverse, and with it

The invention relates to lifting-15 transport equipment.

The purpose of the invention is to improve reliability.

Figure 1 shows the gripping device, a general view; figure 2 - 20

View A in FIG.

The gripping device comprises a yoke 1, a movable cargo carriage 2, a telescopic thrust 3, a housing 4 within which there are 25 two guide pins along which the fixed sleeves 5 and the movable 6 move, a rod 7 with an eye 8 and a wedge 9, the gripping jaws 10 , pivotally connected with the help of 30 links 11 with the housing 4.

Gear sleeve 6 is pressed to the gear sleeve 5 is constantly spring 12.

Cams are compressed among themselves by means of a spring 13. 35

On the housing 4 is also placed an adjustable collar 14, limiting the installation depth of the locking jaws in the product.

The housing 4 is inserted into the hole of the device 40 until it stops. Then, lowering the yoke with a crane and moving the rod 7 to the lowest position, compress the spring 12, which, putting pressure on the gear sleeve 6, causes it to rotate around the rod 7 at an angle of 75, since the contact of the movable sleeve 6 with the teeth of the fixed sleeve 5 is carried out on an inclined surface,

When the rod 7 moves upward, the sleeves 5 and 6 move along the guides of the housing 4, and the wedge 9 expands the gripping jaws 10, overcoming the action of the spring 13, resulting in the capture of the product.

For rasstropovki cargo traverse is lowered by the amount of folding telescopic rods (for example 300 mm) and the rod 7 is moved due to the weight of the traverse to the lowest position. The sleeve 6 extends from the guide keys and pivots 105, and the wedge 9 comes out of contact with the gripping jaws 10, which are compressed by the action of the spring 13.

Then moving the gripping device upward take it out of the cavity of the product.
