The GRW 180 280 from HAMM is the most advanced pneumatic tyre roller in the world.

H series The H series compactors cover a huge spectrum of earthwork applications. The machines are available with weights from 11 t to 25 t, with smooth or padfoot drums. Thanks to the Easy Drive operating concept, all models are exceptionally easy to operate and offer many convenience features. All H series compactors have the 3-point articulation developed by HAMM. It gives them superior driving stability and manoeuvrability even in difficult terrain. VC compactors With the VC compactors, HAMM has developed a dedicated series for especially challenging applications. They crush and compact rock in one operation. The 25 t compactors, based on the H 25i and 3625 HT models, are equipped as heavy-duty machines. Their drum is fitted with 150 tool holders. They can hold cutting tools of the type also used in mining. With the cutting tools, the vibrating drum creates extremely high point loads that crush the rock while the ground is being compacted. 

GRW: pneumatic tyre rollers for every market HAMM also stands out from the crowd in the pneumatic tyre roller segment as it has done since the 1960s, when it was the first ever manufacturer to launch a pneumatic tyre roller. Today, with 18 different models, HAMM ranks among the manufacturers with the largest ranges of pneumatic tyre rollers in the world. GRW 180/280: asymmetric frame provides outstanding overview The pneumatic tyre rollers in the GRW 180 / 280 series can easily be identified from far away on account of their innovative design: their asymmetric frame makes for an outstanding all-round view and provides an unobstructed view of the outer wheels. Added to this is a sight channel, through which the driver can see the running surfaces of the wheels from the cab or platform. An intelligent ballasting concept facilitates rapid adjustment of machine weight with even distribution of weight over both axles.
