Wacker Neuson will show the new version of the articulated joint trench roller for the first time at bauma. With this roller, customers can easily reduce the operating width from 82 to 56 cm.
While in the past only the use of a roller with narrow drums was required for compacting very narrow trenches, customers with the RTx trench roller can simply detach the newly designed attachment drums, thereby reducing the operating width from 82 cm to 56 cm. After use, the attachment drums can be re-attached easily so that the full surface capacity is available for wider trenches.
In developing the new attachment drums, Wacker Neuson placed particular value on the simplicity of assembly. This should also be no problem, even after prolonged use of the roller when the naturally high force effects that occur during compaction have left their traces on the drums. For this reason, the mounting points of the attachment drums are located directly on the slightly inward shifted hub, which lies very close to the axle. This position also ensures a reliable fit, even after repeated stress on the roller. Even the screw heads here are excellently protected against damage from stone chippings.
The threaded holes that are initially exposed after removing the attachment drum are closed using screws designed specifically for this purpose so that no dirt accumulates in the openings, which could affect the subsequent assembly of the attachment drums. In order to facilitate the assembly and disassembly, handles are aligned flush with the inner edge of the drum, protected against dirt and deformation.
The scraper bars significantly contribute to the good compaction results of the roller. With each revolution, the specially reinforced fittings that are attached alongside the drums scrape off the soil that has accumulated on the drums. The new RT is delivered with two different widths of scraper bars so that both versions of the roller provide for an optimal compaction result over the entire operating width. The new RTx roller replaces the RT 56 in the Wacker Neuson product portfolio. The RT 82 with the fixed drum width of 82 cm is still available.
