Hamm extends 'HD+' plus range
By Murray Pollok07 April 2010
On the massive 9000 m2 Wirtgen Group stand, Hamm will be a big attraction for compaction equipment buyers, and there will be plenty new to see.
Hamm continues the roll-out of its HD+ range of articulating tandem rollers, with new mid-range 9 and 11 t class models joining the 12 and 14 t units launched in 2008. The HD+ 90 and HD+ 110 machines are "all-rounders" suited to motorway construction or other large spaces.
The company is also updating its 10 model range of CompactLine articulated tandem rollers in the 1.5 to 4.0 t sizes. The drive train is new, with Kubota engines replacing Hatz, increasing power on all models with drum width of more than 1 m - 15% more in the case of the HD 13 and HD 14 models. The operator ride has been improved with more insulation against vibration.
One notable innovation is the new GRW280 rubber tyred roller, a single model that will replace the existing range from the GRW 10 up to the GRW 24. The key feature here is a flexible ballasting system that allows an end user, or rental company, to vary the weight of the machines from 10 t up to 28 t (using steel or concrete ballast).
In addition, the pedal controls on the old models have been replaced with controls that are similar in concept and look to those on Hamm's other compaction machines, making life easier for operators.
