Abstract: The invention relates to a method for tamping sleepers of a track by means of a tamping assembly comprising at least two tamping units which have tamping tools lying opposite one another in each case and supported on a lowerable tool carrier, wherein the tamping tools—actuated with a vibration—are lowered into a ballast bed during a tamping operation and squeezed towards one another via squeezing drives. In this, for tamping an obliquely-lying sleeper, the tamping tools or tamping tool pairs in a raised position are moved via a control by means of the squeezing drives in the squeezing direction with different adjustment paths in such a manner that the free ends of the tamping tools or tamping tool pairs rotate approximately about a common vertical rotation axis in order to adapt themselves to the oblique position of the sleeper. With this method according to the invention, the necessity of a separate mechanical rotation device is eliminated.

Abstract: The invention relates to a track maintenance machine for tamping sleepers installed on a ballast bed of a track, comprising a machine frame movable on rail-based running gears, track lifting and lining units for correcting the track geometry as well as two 1-sleeper tamping units arranged one behind the other in the direction of the longitudinal axis of the machine that work independently of one another, with each tamping unit comprising at least four tamping unit segments that work independently of one another, adjustable in height via vertical drives and horizontally shiftable in the transverse direction of the machine via transverse drives, with each tamping unit segment comprising at least one tamping tool carrier, with opposing tamping tools being mounted on the tamping tool carrier and coupled via a vibration drive.

Abstract: A tamping machine has a tamping unit for simultaneously tamping sleepers of a track that are positioned directly behind one another. Tamping unit segments are arranged one behind the other. Each tamping unit segment has a height-adjustable tamping tool carrier on which opposing tamping tools are mounted that are coupled to a vibration drive via squeezing cylinders. The respective vibration drive has an eccentric shaft with first and second eccentric discs, the axes of symmetry of which, together with a common axis of rotation, span two eccentric planes that enclose a relative angle to one another. A first squeezing cylinder is mounted on the first eccentric disc. An opposing second squeezing cylinder is mounted on the second eccentric disc. Cylinder axes of the opposing squeezing cylinders enclose a position angle which is approximated to the relative angle of the eccentric planes.

Abstract: The invention relates to a machine for stabilising a track, having a machine frame supported on rail-based running gears and at least one height-adjustable stabilising unit which can be rolled on rails of the track by means of work unit rollers, comprising a vibration exciter with rotating unbalanced masses for generating an impact force acting dynamically in a track plane normal to a longitudinal direction of the track as well as a linear drive for generating a load acting on the track.

Abstract: Ballast (3) located underneath of sleepers of a track is compacted by immersion and squeezing of compacting tools (7) set in vibrations. The vibrations introduced into the ballast (3) during the compacting process are registered as a measure of the ballast compaction. Thus, it is possible to obtain a homogenously compacted track even in the event of different ballast characteristics.

Abstract: Mounting aid for the mounting of rack mounts in frames, in particular racks for use in information technology, comprising at least two relatively to one another adjustable, in particular pivotable legs, wherein the legs at their free ends each comprises a fastening element that is arranged in an angled manner with respect to the leg and is designed for fastening the free ends of the legs to rails, in particular sheet metal angles, of the frame, said rails being directed to each other, projecting inwardly and being provided with a row of holes.

Abstract: A fastening element comprising a first plate with at least two pin-shaped connection elements extending from the first plate, and a second plate with at least one recess, in particular two recesses, for the pin-shaped connection elements, wherein the at least one recess is formed such that the connection elements are insertable into the at least one recess, and wherein the pin-shaped connection elements comprise stop elements arranged, in particular rigidly arranged, on the same and acting in the longitudinal direction of the connection elements and against which the second plate can be brought into abutment when the connection elements pass through the recess of the second plate.

Abstract: An insert element for frameworks, in particular racks, for use in the information and network technology, comprises a plurality of insertion slots, wherein the insertion slots receive insertable cable storage elements each accommodating a cable, the two cable ends of which are guided to the outside via openings provided in the end face of the cable storage element and can be pulled out of the cable storage element at variable lengths.

Abstract: A tamping unit of a machine for simultaneously tamping at least two sleepers of a track, positioned one following the other with regard to a longitudinal direction of the machine, includes inner tamping tines provided for simultaneous immersion into the same sleeper crib and, arranged at either end, a respective outer tamping tine. Each tamping lever mounted on an assembly frame for pivoting about a pivot axis is connected to a squeeze drive. Each squeeze drive is mounted on a common eccentric shaft having an eccentricity with respect to an axis of rotation. The eccentricity causing vibrations of the inner tamping tine is configured differently as compared to the eccentricity causing vibrations of the outer tamping tine.
