Hamm develops new pneumatic-tire roller that is ideal for chipseal

Hamm roller

For the North American market, Hamm has developed the HP 100i articulated pneumatic-tire roller based on the HD+ series. 

The new pneumatic-tire roller was designed primarily for the chipseal process. With five wheels on the front axle and four wheels on the rear axle, the machine meets the requirements of relevant jobsites. 

The working width is 1.7 metres, and the generous overlapping of the tire tracks ensures consistent compaction. The roller is driven by a 55.4 kW Deutz engine.

To match the application, the HP 100i is offered with 6 tonne, 8 tonne or 10 tonne operating weights. Weight is adjusted using ballast kits that use individual modules that may be attached or detached as needed. Furthermore, the 700-litre capacity water tank can be used for ballasting. As an option, the roller can be equipped with a water-sprinkling system, scrapers for the tires, thermal aprons and the HTM (Hamm Temperature Meter).

Cab or platform

Hamm offers the pneumatic-tire roller with open operator’s platform, including ROPS, with protective roof or with a ROPS cab.

Depending on the configuration, cup holders, heating and air-conditioning system, as well as a 12 V power socket, are standard equipment.

The seat height, tilt and the degree of hardness of the suspension are adjustable. The tilt and height of the armrests can also be adjusted at any time. Options such as a comfort exit with tiltable steering column, a backrest extension, seat belt monitoring device, an additional driving lever and comfort armrests on the left and right, as well as a radio, round off the operator comfort features. Operation is simple and easy to understand even without language skills. 

For optimum visibility, the seat operating unit can be rotated 90 degrees to the left and right. In addition, the seat position offers a good view of the tire edges from the cab.

For the cab version, a camera for monitoring the rear space is available as an option. 

For operation on public roads, Hamm offers a lighting package that is adapted to national specifications. As well, the roller can be supplemented with four-way work spotlights, available as halogen lights or as high-power LEDs, and by LED tire lighting.

Intelligent roller driving control 

The working speed of the roller can be increased up to 19 km per hour, while an intelligent travel control system supports smooth and precise reversing behind the paver. Anti-slip control (ASC) is also available as an option for improved traction on rough terrain. 

Thanks to a steering angle sensor and the associated speed control, the speed is automatically reduced during fast cornering, adding an additional layer of safety. The operator can then conveniently return to the preset speed at any time via a rocker switch on the driving lever.

The Hammtronic machine control system also guarantees energy efficiency in the on-board load management. It reduces the engine speeds in such a way that maximum power is always called up while fuel consumption remains low. The optionally available engine stop system, which automatically shuts down the engine during prolonged inactivity, also ensures low fuel consumption and low operating hours. 

For maintenance, all service points are quickly and easily accessible. The scrapers on the pneumatic tires are also easy to change. 

Hamm has developed an innovative solution for changing the center tire.  The tire can be quickly replaced via a folding and sliding mechanism that does not require dismantling the roller’s other tires.
