Tremix now offers a wide choice of alternatives to contractors for the compaction of granular and cohesive soils. The Tremix MS 840 D tampers combine the latest Hatz engine technology with low exhaust emissions and low noise with high working speed for high compaction performance. The well balanced Tremix tampers are excellent for applications on both granular and cohesive soils, where strict requirements are imposed for compaction in confined areas, trenches and repair work. The new tampers strike fast and hit hard providing a high compactive effort. The high amplitude provides the ability to climb grades.
