As can be seen in FIGS. 1 to 3, the cantilever arm is denoted by 1. On the cantilever arm 1 is a

with electric pull 8 provided gate 9 arranged, which can be moved by hand or electric motor along the length of the boom. The vacuum lifting device, which consists mainly of supporting beams 5 and suction plates 7, is suspended from the electric hoist 8. The support beam 5 can be designed with / without a cross member 4. The suction plates 7 are operated by a vacuum pump 6 "Through the structural design of the crane the possibility to lift loads gegebenj within 36O ⁰ to the crane column 2 and to transport. Due to the mobility of the vacuum lifting device by means of the gate 9, the radius of action can experience any change.

The traverse 4 is on the support beam 5 via the articulation point 4 'articulated pivotably in the horizontal plane. The suction plates 7 are on the traverse 4 or * the support beam 5 fixed, but detachably arranged and

Angle of 90 to the cantilever beam 5 »The supporting beam 5 has a horizontally running linkage 12 on the side or at the end with handles 12 '. On the linkage 12 pressure switches 13, 13 'are arranged, which bring about the raising and lowering of the cantilever beam 5 and the movement of the gate 9. Above the linkage 12 there is another pressure switch 13 ^{l on the vacuum lifting device!} arranged for switching off the suction plates 7, which is connected to an electric solenoid valve Ik, which shuts off the suction line 15 and releases the attached load by supplying air consists of transparent material and has an inserted filter insert. This so-called visual filter can be used to monitor the contamination of the filter insert.

The vacuum lifting device has a power cable 17 and a vacuum _{hose 18 f} with the cable 17 and the hose 18 one or more spring pull (s) 20 is / are assigned for tightening.

Above the extension arm 1 is a vacuum storage device formed drilling 21 arranged.

The mode of operation of the object according to the innovation is as follows:

The vacuum lifting device, which consists mainly of traverse 4, supporting beams 5 and suction plates 7, is moved into the area of the goods to be transported via the Gfestangle 12, i.e. the gate 9 is moved by hand or the electric motor on the cantilever arm 1 -Lifting device above the load to be transported, the lifting device is moved down using the electric hoist until the suction plates 7 touch the load. The arrangement of the electro-magnetic valve lh causes the plates 7 'to be automatically sucked in. The lifting device is lowered and raised via the pressure switch 13. The pressure switch 13' causes the gate 9 to move when an electric motor is used.

The traverse h or the supporting beam 5 has a handwheel 10 and guide rollers Ii on _t by means of which the distance between the suction plates 7 can be continuously varied. Haehdem delivered the goods to their destination
