Features for the Wacker Neuson RTLx-SC3 Trench Roller The RT trench roller with the SC3 infrared-remote control offers proven compaction results with safer operation. The smart control uses an infrared signal with line-of-sight control. The articulated trench roller with padfoot drums offers below the axle exciter in each drum to allow for the efficient transfer of compaction energy to the soil for superior compaction results. The compaction of excavations and sub bases of foundations, roads and parking lots is the RT's specialty. Articulated joint increases maneuverability. Below the axle exciter in each drum improves compaction. Low center of gravity improves stability. High and low compaction force. Flexible drum allows convenient conversion of drum width to fit job needs.. Maintenance-free lower end. Engine control module with diagnostic LEDs. Remote Control Infrared technology requires operator to maintain line-of-sight. Patented three receiving eye design provides uninterrupted operation. Machine stops moving and vibrating if line of sight is lost or operator comes within one meter of roller's receiving eyes. 16-channel transmission allows multiple rollers to be operated on job without interference.
