Description

 The invention relates to an automatic lifting and handling device, equipped with arms with variable opening, allowing the gripping of any form of volume with prose both outside by pinching effect, and inside, and possibility of gripping on container. or other, fitted with a lifting ring.

 One of the arms can be fitted with a hydraulic cylinder allowing the remote control of the automatic opening of certain containers at the bottom provided with an emptying hatch.

 The other arm can be equipped with a hydraulic motor or with a hydraulic or pneumatic actuator for dumping by tipping of buckets, bins, containers or fats.

This handling device can be used either with a handling cart, an agricultural tractor or a crane
In known handling devices with automatic gripping, these are specific to a type of product to be handled. Examples: lifting beams for lifting, handling and
tipping of skips.

barrel handling tongs
f5ts rockers
In no case do these devices allow all of these operations to be carried out.

 However in agriculture and industry in general, it is often necessary to handle various loads and volumes, which requires diversified and therefore expensive equipment.

This handling device was fitted with a reversible flow fan for its automatic orientation when used at the end of the crane hook.
The apparatus according to the invention makes it possible to remedy these drawbacks.

 I1 consists of a rail beam on which two sockets move by means of mechanical screws driven by a gear motor. These sockets support gripping arms.

 Several types of accessories can be attached to the end of the arms, such as barrel or bale clamps for textiles or paper, self-centering parts for certain types of containers, etc.

 The end of one of the arms is fitted with a fixing system for a hydraulic cylinder, the control rod of which passes through the end of the arm.

 This cylinder, by means of its rod, does the dfverX rusting of the tilting bottom of certain containers and in particular those intended for the recovery of glass in municipalities.

 The second arm can be fitted at one end with an 1800 motor or actuator for tilting and emptying fats, tippers, bins, containers, etc.

 At the end of the rail beam, a faired fan with reversible flow allows the handling device to be oriented relative to the piece to be handled when the latter is suspended from the hook of a crane.

All the controls, electric, hydraulic or pneumatic, are brought back to the driving position: crane, forklift, etc.
The present invention will be better understood with the aid of an embodiment of a handling device shown diagrammatically by way of nonlimiting example in the appended drawings, in which

born from the control station, has its control rod which,
by penetrating into the self-centering end pieces (10), prevents
any accidental opening by spreading the arms (3)
under the effect of the lifting ring (24).

 The set of 11 handling devices is made in a mechanically welded structure allowing the handling, without deformation, of heavy loads.

 the handling device, object of the invention, can be used in all cases of displacement of loads.

 it finds particularly interesting applications in industry, agriculture, as well as in the handling of glass collectors at the level of municipalities where it allows, in addition to automatic gripping, emptying with control from the crane station, from the bottom of the recuperator, saving time and, as a result, better profitability.

 Of course, the invention is not limited to the embodiments described above and shown, from which we can provide other variants without departing from the scope of the invention.
