Sliding shoe runners
The runners of the sliding shoe continuously slide
over the asphalt that has not yet been removed
during milling operation and are thus subjected to
an elevated degree of wear.
The runners exert downward pressure and
prevent bigger parts from being ripped out.
If the hard metal plate of the runners becomes too
thin, this must be replaced.
In order to reduce overall wear, there is an
adjustable runner on each outer side.
Check the runners on the sliding shoe
regularly and replace and/or readjust if necessary.
- Lower the machine on to the service supports.
- Lift the sliding shoe and secure it in the
uppermost position.
- Ensure that the drive engine cannot be started.
Depending on the operating
circumstances, the adjustable runners can be
installed at a distance of 0-10mm below the
permanent runners.
When removing concrete, e.g. a significantly
lower distance should be set than is the case for
asphalt work.
- If necessary, remove the worn hard metal
plates of the permanent runners; ensure that the
contact surface is level.
- First attach the new parts, then weld them on
properly.
- To install the adjustable runner, loosen
fastening bolts (1) and lock nuts (2).
- Use adjusting screw (3) to set height distance
to permanent runner (4). If the distance has to be
reduced, the runner can be pushed up.
- Retighten fastening bolts (1) and lock nuts (2)
correctly.
Observe the required safety measures
during dismantling and welding!
