Abstract: A vehicle crane having a superstructure that is rotatably mounted on a lower carriage and has a telescopic main jib, where the superstructure consists of a base superstructure and an attachment superstructure arranged in a detachable manner thereon, and the attachment superstructure receives at least one main counterweight. At least one auxiliary support is provided that acts as a hinged support and is fastened to the attachment superstructure, where the rear end of which auxiliary support is suspended via a guying member, and an auxiliary counterweight is suspended from the rear end of the at least one auxiliary support. The invention also relates to a method for rigging such a vehicle crane.

Abstract: In a method for treating aluminum slags (41) in the form of dross or aluminum salt slags obtained in the preparation of aluminum, the aluminum slag (41) in the melting process is brought onto a cooling conveyor (16). A first section (18) of the cooling conveyor is flushed with an inert gas and a second section (29) serves for further cooling of the aluminum slag (41) with introduction of air. In the first section (18), the aluminum slag (41) is cooled to a temperature at which the aluminum slag (41) can no longer be chemically changed by exposure to atmospheric oxygen. In the second section (29), the slag is cooled to a temperature at which the cooled aluminum slag (41) can be processed further to recover the aluminum after leaving the cooling conveyor (16).

Abstract: A conveying system includes conveying cells (14) for accommodating in particular hot bulk goods or lumpy conveying material. The conveying cells have a bottom (16), a front wall (30) and a rear wall (31) in the conveying direction of the conveying system and side walls (15) connecting the latter. The conveying cells (14) open at the top are shielded from the surrounding atmosphere by a stationary and gas-tight top cover (17) that spans the open surface of the conveying cells. Both sealing elements (22; 34, 35) shielding intermediate spaces (32) existing between the conveying cells (14) in the conveying direction from the surrounding atmosphere and also sealing elements (22; 28) projecting laterally on both sides beyond the side walls (15) of the conveying cells (14) are disposed in the bottom region of the conveying cells (14) lying opposite the top cover (17).

Abstract: An air spring for a vehicle suspension, in which air spring the bellows is fastened by way of deformable annular components to the periphery of connection parts. The annular component is fastened at one end of the bellows, to the outer periphery of the connection part in axially spaced-apart clamping regions so as to form an encircling cavity, The annular component, on its outer side, is formed with a rolling contour for the bellows.

Abstract: An air spring (4) includes an air spring cover (8), a roll-off piston (10) and an air spring flexible member (14). The flexible member (14) is attached between the cover (8) and the piston (10) by clamp rings (12a, 12b). An ancillary spring pot (28) accommodates a compression stop (30). The connection of the ancillary pot (28) on the air spring cover (8) is realized in that the air spring cover (8) is made of sheet metal and has a side facing toward the interior space (22) of the air spring. On this side, the air spring cover has a hollow-cylindrical region with a support (24) for the press-fit accommodation of the ancillary spring pot (28). The diameter of the hollow-cylindrical region of the air spring cover (8) is slightly greater than the diameter of the ancillary spring pot (28). The hollow-cylindrical region includes a peripherally-extending groove (26) for accommodating an outwardly formed edge (34) of the pot (28).

Abstract: If a vehicle fitted with a head station is to be mechanically and electrically coupled to other vehicles, attention must be paid to the alignment of the vehicles and the coupling condition of the high frequency plugs interconnecting the vehicles. In order to reduce the labor and time required in the high frequency coupling of the vehicles, each vehicle, except for the one with the head station, is fitted with a vehicle station which is connected to the ends of the vehicles via paired high frequency lines by plug-in components. Before the high frequency signals are switched through in a vehicle, the vehicle station checks whether there is a high frequency signal and whether or not the plugs are coupled.
