Hamm is now offering a novel crusher drum option for its soil compactors.

This innovative feature transforms a soil compactor into a machine suitable for road recycling applications.

Hamm’s marketing director, Gottfried Beer, explained that this special drum broadens the versatility of the standard soil compactor and allows contractors with existing machines to carry out additional types of work. While soil compactors have been fitted with crusher drums before, these have been comparatively limited in the range of applications they can handle and the new Hamm unit benefits from far greater versatility.

The 1.68m diameter drum features toolholders welded in place and these can be fitted with milling type picks. And Beer explained that the machine is versatile. He said, “You can put different cutters on it.”

Mounting the drum on the firm’s H25i soil compactor allows the machine to be used for crushing old concrete road surfaces so that the material can then be removed and possibly processed nearby for re-use as a sub-base prior to laying a new surface over the top.

One application where the machine has been tested is on a highway in Austria, where it was used to break up the old concrete surface. Another duty has been to break up the floor of a new tunnel close to Leipzig, as the rock was too aggressive to be milled and would have resulted in excessive cutter wear. Meanwhile, the machine has a third application, for secondary breaking of rock found in uneven surfaces.

Beer explained that the customer can adapt the machine to the application requirements by fitting different types of picks in the holders, as well as padfoot plates for more conventional compaction duties. As the concept is still new, Hamm is still discovering options for this adapted machine and Beer said, “We can use four different cutters now but we’ll possibly have more in the future.”
