When conveying bulk goods through. Self-ingredient one uses. to prevent parts of the gripper contents from falling special end links attached to the gripper that create a floor gap cover between the two gripper shells. However, with these arrangements no guarantee that, despite this, at high speeds or

ίο due to fluctuations in the gripper parts of the material to be conveyed can fall off the side of the cover plates. Even! is absent from these known arrangements protect against the fact that when the gripper is overfilled, the conveyed material can fall over the walls of the gripper. Finally these types have with the gripper itself arranged protective devices have the disadvantage that the latter easy due to the actual gripper operation

ao be affected.

The aim of the invention is to create a protective device by means of which the disadvantages mentioned are avoided and it is achieved that a special protective net underneath the roadway can be omitted.
The subject of the invention is shown in the drawing in an exemplary embodiment in Fig. 1 in a front view and in Fig. 2 in a side view.

"It means α the self-gripper, which can be raised and lowered in a known manner with the trolley b . A frame c encompassing the self-gripper α is attached to the trolley, at the lower ends of which there are two gripper dimensions that can swing about axes d, d ¹ adapted protective floors e, e are hinged ^1, ο side surfaces thereof advantageously with wire mesh or the like are provided, whereas the bottom faces of:... sheet are formed / and f ¹ are double-armed to d, and Rf is a ^one movable lever, at one arm Counterweight g or g ^{1 is} arranged. Its other "arm carries a fork which, in cooperation with the gripper going up and down, causes the protection device to be closed or opened. So if the gripper is lifted after filling, it hits the fork-shaped part of the lever /, Z ¹ in the corresponding height position and pushes this lever and thus also the protective bottoms e and e ¹ into their closed position, in which they are during the White

terbefeerung of the gripper are kept and prevent falling of the conveyed material.

In order to prevent bulk goods from falling over its upper end edges when the gripper is overfilled, the sides of the frame c are also provided with wire mesh or the like. At the lower closing edges of the protective shelves e and e ¹ , in

ίο, in a manner known per se, expediently a protruding sheet metal k attached to securely close the protective floors.

By the invention it is thus made impossible that during transport of the gripper Parts of bulk goods either as a result of insufficient closing »of the gripper or fall if the gripper is overfilled.

So that the device can also be

ao ger career of the cat can always set vertically, it is attached to a pivot point i on the trolley so that the gripper can safely enter and exit. In order to prevent oscillating movements of the device as a result of high driving speeds, springs k, k ¹ or the like are provided.
