Especially for handling stacks of bales Laying device

The invention relates to a loading device with which Help a variety of τοη in uniform, precisely designed State objects can be lifted, transported and passed on. The invention geaHfie Torriohtung is particularly suitable for the handling of a plurality of bales, which are thrown by a balltn stacking device have been put together.

There are bale stackers that produce a two-story, practically rectangular stack from five bales, in which two bales forming an upper layer are arranged above a lower layer consisting of three bales, the bales of one layer at a right angle to those of the other position are arranged. The bales are assembled at the production site into stacks with the specified structure, which are later picked up as a unit and loaded onto a va ^ son or truck and transported to a storage place. It has been shown that such stacks

This "introduction of the ß ab el sink en "under a pile of bales of the type mentioned is difficult in that the one bales under the through The thrust exerted by the fork can often be pushed out of the stack and a reorientation carried out by hand Before the pile can be lifted, the bales need to rest flat to pick up the bales also only on the top of the fork; if the loader is now moving from uneven terrain to Side tilts, one of the bales can fall out of the stack and often result in the collapse of the stack and loss of bale material. To hand in the forks are usually tilted so that the bales slide down from them under the force of gravity, which in turn destroys the stack arrangement and uneven stacking of the bales on a transport vehicle or bring axt eich to the storage location.

This movement also has the consequence that the adjacent ends of the links 106 move practically linearly at the same time in the direction of the abutment wall 30 and in the transverse direction in opposite directions against their associated stand 76, around the legs 70 of the opposing arms from one another remove su. During this movement, the legs run down the upper and lower balls 50 and 52, respectively, when the arms move from their retracted position according to Pig 4 into the sucked-out position according to Pig. 5 can be moved.
