Abstract: A crane trolley, especially a single-rail trolley with a short overall height, with a traveling mechanism frame (2) having a hoisting mechanism (1), which can travel by running wheels (3, 3a) on a rail, especially a lower flange (4a) of an essentially horizontal beam (4), wherein at least one running wheel (3a) can be driven, and a friction roller (10) interacting with the driven running wheel (3a) is arranged on the underside (4b) of the rail. In order to create a crane trolley that guarantees a reliable reduction in the slippage of the driven running wheel (3a) with a simple design, a pair of friction rollers (10) is provided, which may be positioned against the underside (4b) of the rail by adjusting the spacing from each other via a common pressing mechanism.

Abstract: The invention concerns a detachable fastening of a cable (2) on a cable drum (1), especially a wire cable, with an opening (1a) arranged in the cable drum (1), with an enlarged cable end (2a) on the cable (2) and a connection piece (4), by which the cable (2) with its end thickening (2a) is detachably secured to the cable drum (1) in the region of the continuous opening (1a). The connection piece (4) may be detachably secured in the continuous opening (1a) and the enlarged cable end (2a) be detachably secured to the connection piece (4).

Abstract: The invention concerns a hoisting device with a drive unit (1) including a motor and a transmission, a drive shaft (2) which can be driven by the drive unit (1), with drive flange (3) which can be secured to it, as well as a cable drum (4) which can be connected to the drive flange (3), wherein the torque of the drive shaft (2) can be transmitted by a coupling to the cable drum (4), wherein the coupling consists of at least one coupling element (9) arranged essentially by form fitting between the drive flange (3) and the cable drum (4), being constructed from individual coupling segments (9a), which have drive cams (10) pointing radially inward and outward on both sides, which engage with corresponding recesses (11) of the two adjoining structural parts (3, 4) that can be coupled together for the torque transmission.

Abstract: A breast box nozzle for a paper making machine or the like is shown as having an adjustably positionable shutter member which can be moved generally further and lesser into the path of flow of a stream of pulp stock as to thereby determine the thickness of the discharged stream of pulp stock. A support arrangement applies a pressure to the shutter member as against a downstream side thereof in order to counter the forces generated by the stream of pulp stock upstream of the shutter member and applied as against the upstream side thereof tending to undesirably deform the shutter member. The support arrangement includes an elastomeric member generally interposed between a relatively fixed support member and a downstream side of the shutter member.

Abstract: A rolling device for rolling up a sheet onto roll formers or spools: a roll former is inserted between and supported on two supporting rollers and a sheet is wound on it; the finished wound roll on its roll former is lifted off one of the supporting rollers looping the sheet, and the slack loop section is stapled to the next roll former; the sheet is cut off at the new roll former.
