Shimlift
KamPa BV has developed an innovative rail attachment for sleepers – ShimLift – that eliminates the most important problems at transitions from ballast to ballast-less track. Transitions occur at level crossings, bridges, viaducts and tunnels. The height-adjustable attachment also proves its usefulness on other parts of the track where local subsidence has to be corrected.
ShimLift uses a plastic wedge that is slid under the rail and moves over a counter wedge on the sleeper. Sagging in the track at transitions creates space under the sleepers. This phenomenon is known as blind suspension and causes the sleepers to strike when the train runs over them.
With ShimLift blind suspension can be combated very effectively, much better than with a tamping machine, which loosens the ballast bed and whose effect is only temporary.
