Description

GERMAN

In the known handling devices for loading goods, tipping buckets are automatically activated at the place of unloading " tilted by a tilt release, which is arranged, for example, by fixed or displaceable as required Stops or curved rails takes place. It is also known to thereby add a loading bucket tilt so that it is held laterally by a hook during the lowering by the suspension rope. The principle of a self-pivoting loading boom is also known, which consists in the fact that the lower The pivot point of the boom is laterally below the pivot point in the mast head.

In the device according to the invention, a special device for bringing up .and mooring a retaining hook is used on the tipping bucket, with the eccentricity between the pivot point of the boom and pivot point in the mast head or mast foot is used. This becomes a Significant savings in work and time are achieved when loading and unloading the bucket.

The invention consists of a device for tilting a loading bucket that can be raised and lowered is suspended from a self-pivoting loading boom, the pivot point of which is below the side under the The pivot point is in the mast head and thus to the side of the mast base and is at an angle to the loading mast is adjustable, the loading or tipping bucket at the beginning of the tipping movement on its mast-side Page held by a hook and the tilting movement by lowering the tilting bucket through the Load hook is achieved; it is characterized in that the retaining hook on a pendulum-like Arm is suspended at the upper end of the boom, with a cross arm of this pendulum-like arm a weight is attached to act on the pendulum-like arm to engage the retaining hook bring up to the tipping bucket so that a pulling rope of constant length engages on the pendulum-like arm, the other end of which is attached to the mast base, and that the lower pivot point of the loading boom the side of the mast base facing away from the unloading point at which the loading bucket is tipped or the lower side Attachment point of the pull rope is so that an eccentricity is created which causes the pull rope hangs limply at the unloading point and allows the hooking of the retaining hook to the tipping bucket, while it is stretched at the approximately diametrically opposite loading point and the pendulum-like arm with the retaining hook against the effect of the weight after the mast pulls back, so that the tipping bucket from Retaining hook is released.

tree shown. In Fig. 1 the loading bucket A by slackening the cable E is held laterally by the retaining hooks D and tilted during lowering. Fig. 2 shows the loaded bucket before lowering, the rope B is taut. Figs. 3 and 4 each show an overall view from the side and from above. A tipping bucket A hangs on a pivotable loading boom or boom B. At the upper end of the loading boom B , a load hook D is suspended from the pendulum-like arm C. To a transverse arm of this pendulum-like arm a weight is attached, which shall aim in bringing the pendulum-like arm for engagement of the retaining hook to the tilting bucket D A. A pull cable E of constant length, the other end of which is attached to the base of the mast F , engages the pendulum-like arm C. When the boom B swings from the loading point to the unloading point or vice versa, the rope E slackens or pulls as a result of its attachment to the side of the boom pivot point G. The eccentricity GF thus created causes the pull rope E to hang slack at the unloading point and the hooking of the retaining hook D on the tipping bucket A is enabled; when the bucket A is lowered, it is then tilted. In contrast, the rope is tensioned on the way to the approximately diametrically opposite loading point and the pendulum-like arm C with the retaining hook D is pulled back towards the mast against the effect of the weight. This then releases the tipping bucket from the retaining hook.
