Hamm HP Series Pneumatic Rollers 1

The operator’s platform, water-and-additive sprinkling system, and ballasting system have all been upgraded on Hamm HP Series pneumatic-tire rollers.

All model variants in the series share a common platform, including HP 180/HP 180i models with operating weights ranging from 8 to 18 tonnes and HP 280/HP 280i models with operating weights ranging from 10 to 28 tonnes.

The operator’s platform gives him or her a bird’s-eye view of the machine and the job site. The ISO 5006-2017 operator’s field of view standard is met by all models. The HP Series has a small number of switches on the operator’s platform, and color-coded groupings aid in operator guidance.

The joystick on the armrest is used to control the vehicle. Because the brake pedal is a part of the seat-operating unit, it is accessible regardless of seat position.

The new machines use the Hamm asymmetrical-frame concept, which allows for a clear view of the outer flanks of the front and rear wheels by providing track offset between the front and rear wheel sets.

The new machines also have ballasting flexibility, which allows the operating weight to be quickly adjusted to suit the asphalt type, layer thickness, and application. Steel or concrete prefabricated ballast bodies can be inserted or removed from the large ballast compartments between the wheel set.

A redesigned water tank is large enough to last an entire working day without needing to be refilled. According to Hamm, a 1,500-liter supplemental water tank is available and can be used as a water reservoir for the sprinkling system or as a flexible supplemental weight.

Interconnecting pipes connect the supplemental water tank to the basic water tank. A C-pipe connection complements traditional filling for quick refilling, allowing the entire tank to be filled in under three minutes.

Special asphalts require spraying an additive onto the roller’s pneumatic tyres, which is stored in concentrated form in the additive tank and mixed with water as needed.

For various addition levels, the additive tank has a level monitoring system that is controlled from the operator’s platform. During compaction, the roller doses and mixes the additive according to the specification.
