Bump cutters are mobile grinding machines for the treatment of surfaces made of concrete or asphalt. A grinding shaft, equipped with diamond saw blades and distance plates removes material in a grinding process. The working width depends on the used machine type and on the number and types of diamond saw blades. For make different surface patterns, the grinding shaft can be equipped with various combinations of blades and distance plates. In general, 3 methods are distinguished – grinding, grooving and bump cutting.
The RSG 4600 is the top model of the RELLOK bump cutters. With a maximum working width of 1400
mm, it can treat large areas within a short period. Beside the main engine the machine has a separate diesel engine for the grinding shaft only. To remove the slurry effectively, the RSG 4600 has two powerful slurry extraction plants.

The rotating brush (rotates in reverse direction), raises loose material from inside of the joint, such as slurry or small stones, to the front. The result is a largely dust-free joint, which forms the basis for the durability of the sealing compound to be poured into the joint in the next step.
The RSB 120 is equipped with a two-stage air filter which effectively prevents the penetration of dust into the motor. The filter cartridge can be replaced without tools.
