Alignment tampers have little "fingers" that dig into the ballast, grab the track (and ties) and shake them, to adjust the profile of the track.
The Production and Switch alignment tamper has a buggy on the front. The buggy is used to line and level the track by shooting light from the boxes mounted on the buggy to the back of the machines where there
is a collector, between the source and the collector is a shadow board the
cuts the amount of lift (the height the track is lifted over the length of the
machine) when the shadow board breaks the beam. Normally (In
Australia anyway) the lining is done by another laser that sits on another
buggy and is set up to line to the center of the track however this would
be secured away as they are expensive and easy to wreck. As stated
above the tynes (fingers) and mounted on work heads in groups of four to
compact the ballast under the sleeper in the four quadrants of the rail foot.
The work head and tynes and all controlled by the machine with the
operator moving the machine forward and pressing the button to plunge
the workhead into the ballast while the machine applies the require lift to
the rail. Once the machine has made a few passes the track will have most
of the voids under the rail seat compacted and will hold the line and level
under use. The difference between a switch and a Production tamper,
normally switch tampers don't use the buggy due to the short length of a
switch. The turnouts are lifted by track jacks to the correct level or the
machine makes a number of passes to lift the turnout, the work heads are
require to move sideways to allow for the diverging rails and frogs and so
the tamper must have this ability in order to be a true switch tamper. If the
heads are fix the machine will be a production tamper for track, movable
production / switch. Sorry to bore you all but someone might find it useful
or interesting- Cheers- Stephen Devenish - JohnnyR@bigpond.com |
