The grinding machine RotoMatic R58, with its compact
construction, is extremely suitable for grinding elastic synthetic
sports surfaces, particularly on small areas, boundary
zones, alongside curbstones and for projecting boundary
lines. The RotoMatic R58 is steered by hand and the operator
has a clear view of the work surface and the edge
of the grinding disc. Three solid rubber wheels on bearings
enable easy manoeuverability and ensure an accurate
and safe operation. The arrangement of the wheels prevents
the grinding disc from tilting, even when the surface
is uneven.
The grinding disc is mounted on the crankshaft of a 4-stroke
petrol engine. In this way the power provided by 13 HP
is directly transmitted to the grinding area. The adjustable
grinding pressure is set by hand and held constant by the
machine. This prevents fast wear of the grinding disc and
damage to the surface. For a brief interruption or when the
work is finished, the grinding unit can be pivoted upwards
by a Bowden cable, and locked in this raised position by a
security lever. With a few simple touches the RotoMatic R58
can be fold up for transport or storage and requires little
space.
