Quick-change toolholder system HT22 PLUS HD for cold recyclers and soil stabilisers
The quick-change toolholder system HT22 PLUS HD is primarily characterised by its higher resistance to wear. The system's exceptionally long service life makes itself felt on the construction site through the considerably longer replacement intervals. It is also characterised by the prismatic design of the contact surface.
Cutting tools for cold recyclers and soil stabilisers
GENERATION A² round-shank picks are the all-rounders in the portfolio of round-shank picks for cold recycling and soil stabilisation and feature impressive product characteristics such as the high fracture toughness of their carbide tips.
Quick-change toolholder system HT22 PLUS for cold milling machines
The quick-change toolholder system HT22 PLUS is primarily distinguished by its higher wear resistance. The system's exceptionally long service life leads to noticeably longer intervals between replacements during operations on construction sites. It is also characterised by the prismatic layout of the contact surface.
The all-rounder among picks for cold milling, GENERATION X² °impresses thanks to its exceptional product features such as the optimised wear plate with its unique groove profile.
Milling and mixing rotors for cold recyclers and soil stabilizers
Challenging operating conditions such as the powerful cold recy-cling, granulation or stabilization of coarse-grained soils make ex-treme demands on the cutting tools. This calls for perfectly matched components designed to meet the highest performance requirements. They can be relied on to provide high milling and mixing performance while ensuring maximum resistance and durability at the same time.
With electric rollers, HAMM is responding to the growing demand for alternative drive technologies in road construction and earthworks. The machines enable compaction without local exhaust emissions at the site and are characterised by their quiet operation.

Working on a range of construction sites in the earthworks and asphalt sectors requires rollers to have optimum driving and steering characteristics. To meet this need, HAMM has installed three-point articulation – a more sophisticated upgrade from conventional articulated joints – in all compactors and tandem rollers in the HD CompactLine, HD and HD+ series as standard.
Cold recycling with foamed bitumen has become an established technology worldwide and is now increasingly moving into the focus of road authorities and construction companies for use in the rehabilitation and new construction of road pavements. Cold recycling with foamed bitumen produces flexible and highly durable base layers. Being a part of the pavement structure, these are the perfect foundation for the final asphalt overlay to be built at reduced layer thickness. Foamed bitumen is produced from approx. 175 °C hot road-grade bitumen using state-of-theart technology. Microprocessor-controlled injection systems installed in the WIRTGEN recyclers produce the foamed bitumen and inject it into the mineral aggregate in precisely metered quantities.
HAMM AG – specialist in rollers for road construction and earthworks
HAMM AG is a company in the WIRTGEN GROUP, a global group of companies in the construction machine industry with five main plants in Germany, local production facilities in Brazil, China and India, and a worldwide sales and service network. Within the WIRTGEN GROUP, HAMM AG is the specialist in rollers for the road construction and earthworks sectors.
Ten per cent of employees in the HAMM AG plant work in the research and development sectors. They all have a clear purpose to follow in further developing and creating efficient machines. This purpose has by no means developed only in recent years – as a glance at the history of the company will show you.
Maximum structural integrity and wear resistance are vital qualities for the picks to ensure highly precise and productive milling and cutting operations. The picks are firmly anchored in the heavy-duty WIRTGEN toolholder systems and can be replaced quickly and easily right on the construction site.
In the Smart Compaction product range, HAMM offers various solutions for intelligent and simple compaction, compaction documentation and compaction control. The focus here is on digital interfaces between the operator and the machine.
