Our service goes further

You can contact us for infrastructural products and rolling stock. But our service goes further. Kampa supplies, advises and stands for sound project management. If you have a question about noise reduction, we can help you come up with flexible and creative solutions. Solutions that we or our suppliers test extensively, including through vibration analyses, modal analyzes and fatigue tests.
To protect the noise-sensitive residential buildings from noise emissions and vibrations, Calenberg’s durable and maintenance-free mass-spring system USM 1000 W was installed over an area of 500m2.
KamPa BV supplies innovative products that contribute to reducing LCC (Life Cycle Costs). Other innovative products reduce the noise or vibrations at the source, so that local residents are less bothered by railway noise.

Vibration technology has become a high-quality science over the years.

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.
