Hamm reports that its H series single drum compactors are proving highly successful, particularly the H5 and H7 models introduced last year. The firm is continuing to upgrade the range with the sophisticated driving system now being introduced to all of the Tier 4 Final/Stage IV compliant soil compactors weighing 7tonnes or more. This sophisticated drive system will also be fitted to the soil compactors for sale in less regulated markets in the future however.
The H5 and H7 variants are said to offer precise operation as well as good traction and ground clearance due to the hydrostatic drive system. The high traction means that these machines offer better climbing ability than earlier generation machines, while the H7 can also be operated with a dozer blade for smoothing surfaces out ahead of the compaction process. Meanwhile the sloping engine cover and short, compact design help provide good all round visibility. Versions of the H5 and H7 available include models with smooth and padfoot drums as well as the Vio variant with both drum oscillation and vibration.
A special variant of the larger H25i meanwhile is the VC, which is fitted with a modified drum. This can be equipped with standard padfoot plates or with picks, for use in rock breaking applications. The picks are similar to those used in road recycling applications and can be quickly changed for maintenance or if the user wants to change the configuration of the machine to a padfoot type.
