Abstract: The invention relates to a cable swivel for connecting a cable or a retainer to a component, in particular a Kelly bar, which is rotatable relative to the cable or the retainer, with a stationary first swivel part which can be fastened on the cable or the retainer, and a rotatable second swivel part which is supported in a rotatable and axially fixed manner on the stationary first swivel part and can be connected to the component. Furthermore, in the case of the invention provision is made in that the rotatable second swivel part is of sleeve-shaped design with an axial passage and in that on the stationary first swivel part a connecting pin is designed which at least partially extends axially along the passage of the rotatable second swivel part.

Abstract: A track-supporting roller assembly, according to the disclosure, for supporting a crawler track of a crawler chassis includes a bearing unit and a track-supporting roller rotatably coupled to the bearing unit. The track-supporting roller includes at least one supporting body made of plastic. The supporting body serves as a damper and prevents a metal-on-metal contact between track chain links of the crawler track and the track-supporting roller. The track-supporting roller assembly according to the disclosure ensures a reduced noise development in the crawler chassis. At the same time, it is possible to also reduce the wear of the track-supporting rollers to a considerable extent.

Abstract: A drive shaft module for a material conveyor system of a construction machine comprises a drive shaft and at least one first mounting which is designed to hold the drive shaft at at least one first bearing location. The drive shaft comprises different segments which are joined by friction welding, and the mounting is connected to the drive shaft such that the complete drive shaft module may be detachably fixed, in a preassembled state, in or at the construction machine.

Abstract: The disclosure relates to a conveyor screw for a material conveyor system of a construction machine. The conveyor screw comprises a conveyor section which is configured to convey bulk material, and a driving section which is designed to receive a driving torque or a driving force and to transmit it to the conveyor section. The disclosure is characterized in that the conveyor section and the driving section are connected to each other by friction welding.

Abstract: A road paver F having a primary driving aggregate P with a combustion engine M, particularly a diesel engine, the crankshaft 22 of which extends to a power output region within a casing 20 of a clutch and/or a flywheel. A generator R is driven by the primary driving aggregate P at least for supplying electric heating devices H of the road paver F with electric power. A distribution gear mechanism 30 for pumps is mounted to the primary driving aggregate P. The generator R being a generator with permanent magnet excitation is mounted to or into or in lieu of the casing 20. A drive train 29 connected or connectable to the power output region of the crankshaft 22 extends to the distribution gear mechanism 30 for pumps and through the generator R.

Abstract: In a tracklaying gear with a frame having an idler wheel linear guide in which at least one guide piece holding the idler wheel axle is movable, and on which a tensioning means of a tensioning device supported in the frame can act in the guidance direction, at least one mechanically guided and centered elastomer spring body is installed to bulge under axial compression, such that the spring body can be readjusted, the elastomer spring body consisting of an elastomer material largely incompressible as a spring.

Abstract: The present invention describes a road finisher for laying a paving material, comprising a material bunker for paving material and a spray jet module. In order to increase the spray carrying capacity in a structurally simple manner, it is suggested that a reservoir unit comprising a spray reservoir and a paving material reservoir should be arranged in the material bunker.
