Stone pile gripper / The invention relates to a stone pile gripper with swei yoa a lever system carried and movable against each other under the lifting force acting on the lever system clamping jaws "

The safety regulations call for protective devices to prevent stones from falling from one in the Stacks of stones held by the gripper are reliably prevented will.

The object of the invention is to create one of these stipulations sufficient stone pile gripper.

The solution according to the invention consists in that the clamping jaws are jointly connected to at least one side wall part and are mounted on the lever system so that they can be pivoted about a common axis that is transverse to Kiemmh & ^ keiieb & xie the clamping jaws and, if necessary, the stack held by them, while the outer side is located

Above this SrMgers 6 there is a lifting beam 8, the one on the support 6 by means of a telescopic connection is led. The device is also provided with two I «shapes Levers 10 and 11 are provided, which are in the same vertical Level like the questioner 6 lie. The lower! Ends of these Levers are articulated at 15 and 12 with the cross members 14, 14 ' connected to the crosswinds · The top ends are $ 1, 16 By means of two?

- 4th

At the lower end of the lower leg of the lever 11 there are two cams 31 »32, which are in the not tilted and in the tilted position of the pliers with a locking member 34 to be operated by a lever 33 susaaaien work, which is attached to the box-like device. There is also a handle 35 on it arranged to facilitate tilting and handling of the box-like frame.

The effect of the clamp is as follows: Before the open at the bottom of box-like Hahmen is provided over a stack of bricks _S is put the lever 29 in such a position 'that the side wall parts diverge. When the box-shaped paralyze is settled around the pile of stones, the lever 29 is thrown, whereby the side walls move towards each other. As a result of the Hefce movement that follows, the beam 8 is displaced vertically with respect to the bracket 6, so that the lower ends of the legs hanging down, the levers 10, 11 and, as a result of the articulated connection of the upper ends 15, 16 with the lifting beam 8, are rotated around the points 21, 22 , whereby from these lower ends of the lever 10, Π a force and a movement are exerted on the side wall parts in the sighting according to arrow P (Fig. 1). In this working stage, the crouch 31 engages the pawl 34. Once the side wall parts have gripped the stone stack, the box-like device is tilted after the goose © has been completely raised.

For this purpose, the latching between is by means of the lever 33 the lock 31 and the pawl released and after that öanse is tilted over 90 °, this same lever 33 provides a lock between the cam 32 and the pawl 34 brought about so that the received stack rests on the closed side wall part and thus none There is a risk that the stones picked up could fall out. ·

Once the stone has reached the set-down stack, the gripper is aurückgekippt and placed on the ground with its trnterfläche. By means of the lever 29 and the rods 23, 24 the side wall parts are moved away from one another according to arrow P '(Pig «1), so that the clamping effect of the rare wall parts on the stone stack is canceled. By keeping the lever 29 in this last-mentioned position holds, the side wall parts can no longer move towards each other during a subsequent lifting movement of the gripper, so that the stack of stones is no longer taken along during this lifting movement.

The pliers described has a very simple construction and meets all safety regulations, so that they can be used very expediently for the traneport of stones on a construction site.
