Abstract

A device for mounting on an implement carrier such as a fork lift truck, hoisting crane or the like in order to move, hold or lift an object. The device comprises—a carrier part which is mounted on the implement carrier preferably by the carrier part being in the form of a sleeve which is inserted on the implement carrier'"'"'s fork structure, and—a holding part which is attached to the carrier part, the holding part being provided with at least one securing device with characteristics that make it possible to secure an object by contact between at least one of the object'"'"'s surfaces and the securing device,—a trigger that ensures that the forces acting between the object'"'"'s surface and the securing device are broken or discontinued, thus releasing the object.

Claims

1. A device for mounting on an implement carrier such as a fork lift truck, hoisting crane or the like in order to move, hold or lift an object, characterised in that the device comprises

a carrier part which is mounted on the implement carrier preferably by the carrier part being in the form of a sleeve which is inserted on the implement carrier'"'"'s fork structure, and

a holding part which is attached to the carrier part, the holding part being provided with at least one securing device with characteristics that make it possible to secure an object by contact between at least one of the object'"'"'s surfaces and the securing device,

a trigger that ensures that the forces acting between the object'"'"'s surface and the securing device are broken or discontinued, thus releasing the object.

2. A device according to claim 1, characterised in that the object that has to be moved, held or lifted is an object with a surface where at least some portions are smooth or an object composed of thin metal sheets, for example of the white goods type.

3. A device according to claim 1,

characterised in that the securing device is one or more electromagnets (1) or permanent magnets (1).

4. A device according to claim 1,

characterised in that the securing device is suction cups or similar devices that can create negative pressure.

5. A device according to claim 1,

characterised in that the trigger is a guide part which is rotatably mounted in the holding part, where on being rotated the guide part pushes the object away from the securing device to a distance which is sufficient for the forces between the object and the securing device to decrease and the object to be released from the holding device.

6. A device according to claim 5,

characterised in that the fork can be telescoped and that there is a fixed connection between a stationary part of the fork and the guide part, so that the guide part will be rotated when the fork is fully extended telescopically.

7. A device according to claim 1,

characterised in that the trigger interrupts the voltage to the electromagnet or causes the negative pressure to be discontinued, thus releasing the object.

8. A device according to claim 1,

characterised in that the trigger is operated manually or by means of an actuator.

9. A device according to claim 1,

characterised in that one or more supporting edges are permanently or removably mounted in the lower edge of the holding part.

10. A device according to claim 1,

characterised in that the holding part is oriented substantially vertically relative to the carrier part and/or that the holding part is mounted rotatably or preferably hingedly on the carrier part, thus enabling the holding part to be moved to another desired position and fixed in this new position.
