Everything about the HD+ series vibratory steel drum roller compactors is geared to performance: the generously sized tanks and the large drum diameters, as well as the powerful traction and vibration drives. The XXL cab or platform is extremely large and comfortable. From there, drivers have an excellent view of the drums, the water sprinkling system and the surrounding area. With their exceptionally favorable weight distribution, the HD+ series rollers stand out in terms of handling and compaction characteristics. Whether straights, slopes, bends or roundabouts – these rollers quickly produce perfectly smooth surfaces. And, thanks to Hammtronic and other intelligent solutions, the HD+ is very economical to operate, making these rollers are the perfect choice for efficient compaction of large areas.

Features
Ergonomics
Operators access the platform via a wide stepway with broad footplates. The convenience features continue with an optional rearward-tilting steering column that makes getting on very easy. The comfortable seat includes two armrests and can be supplied with a backrest extension and fabric covers. The driver’s seat can be rotated and moved sideways to the edge as standard, the height and springing are adjustable.
The cockpit includes amenities such as 12 V sockets for charging a mobile phone or for a cold box, ample storage space, multiple drink holders and fresh air nozzles. On request, a mobile cold box can also be provided as well as a lunchbox holder in all ROPS machines.
Three-point Articulation
Hamm’s three-point system is the key to exceptionally even weight distribution, first-rate directional stability and high stability when turning together with great resistance to tipping. This benefit is particularly apparent when compacting on curved sections. Surfaces with impeccable evenness and no deformations are produced rapidly.
Water Sprinkling System
With their large water tanks, HD+ series rollers are equipped for long working days without stopping to top up. Here, the desired water delivery is automatically adjusted in line with speed. Two alternately operating water pumps, an optional antifreeze filling system and a triple water filtration system ensure maximum availability.
The position and mounting of the spray bar also help to ensure high quality: it is positioned in front of the cross member so that the driver has the sprinkling system in view at all times and can quickly adjust the water volume. In addition, the spray bar can be mounted and removed in a matter of moments.
Easy Drive System
HAMM has developed the innovative “Easy Drive”, an advanced operating concept that stands out for its simple, quickly grasped operation and ergonomically optimised features.
The Easy Drive rollers are steered using a steering wheel. For the drive control, the driver uses the joystick. The important buttons are positioned there so as to be visible to the driver at all times. All other operating elements are arranged according to the following rule: the more frequently they are used, the closer their position to the joystick.
Order prevails on the multifunction armrest as well: the functions are pre-selected at the top and adjusted at the bottom. The status displays are grouped on the dashboard next to the steering wheel, likewise the infrequently used buttons. All displays and buttons are colour-coded. Here, the principle is the same as with other HAMM rollers: same colour – same function group.
Maintenance
To ensure fast and thorough servicing, HAMM uses the WIRTGEN GROUP’s service diagnostic tool WIDIAG. The interface for this system is easily accessible in the multifunction armrest. For customers who also want to exploit the benefits of remote diagnostics as part of an efficient fleet management system, the HD+ can be equipped with the WITOS FleetView telematics system.
With long maintenance intervals and few maintenance items, HAMM makes life easier for workshop technicians. For example, all items requiring routine maintenance are grouped together on the same side of the machine. Here, a large, wide-opening door to the engine compartment provides optimum access to the filters and dipsticks.Related
