Wirtgen and HD 14i TT, the new compact pneumatic-tyre roller by HAMM

The agile and versatile rollers on the HD CompactLine are user-friendly all-rounders for road-building and gardening and landscaping. HAMM, therefore, covers a range of 1.5 t to 4.5 t. In addition to the tandem and combination rollers, their range of products has always also included a compact pneumatic-tire roller. This has now undergone a facelift and is now available under the name HD 14i TT. The “i” in the name informs you that it fulfills the requirements of the exhaust emission standard EU Stage V/EPA Tier 4.

Strong compact rollers

The HD CompactLine from HAMM is the world’s most comprehensive series in the compact segment. For the German market alone, there are currently 24 compact tandem rollers available, including the HD 14i TT pneumatic-tire roller. The series is rounded off by country- and market-specific machines, for example in China. All of the models in this series are extremely compact. They are therefore ideal for use on small and cramped construction sites. Their most important features include perfect visibility thanks to a tapered front vehicle, a low machine height, and great transport and driving characteristics. The three-point articulation in particular allows for unique driving stability and great directional stability. The drum width on these articulated rollers ranges from 0.80 m to 1.38 m. There are also models with oscillation for all markets. The agile compaction machines are user-friendly all-rounders for compacting road surfaces in road construction as well as soils and paths in landscaping.

HD 14i TT: Facelift and new engine

HAMM offers the reworked pneumatic-tire roller in the HD CompactLine under the name HD 14i TT. With a working weight of around 4 t and a working width of 1276 mm, it is suitable for repair work and for compacting small paths and surfaces. It shows its strengths wherever asphalt has to be gently compacted or pressed without vibration. Thanks to the compact dimensions, compaction can also be effortlessly carried out in extremely narrow spaces. Added to this is a large side clearance, meaning that the HD 14i TT can compact right to the edge on curbs and small walls. Its economic, quiet actuation is also impressive. The Kubota engine with DOC-PDF and 37.4 kW power fulfils the requirements in accordance with EU Stage V/EPA Tier 4 for the EU, North America, and all other countries with comparable emissions legislation.

Optimum visibility

The design of the HD CompactLine with a wasp waist always guarantees excellent visibility. With this facelift, HAMM has yet again improved visibility. The roller fulfills the new, strict requirements of the “Field of view standard” DIN EN 474 and therefore offers even greater safety on the construction site as well as a better view of the surface that is to be compacted.

Great basic equipment and a range of options

The standard equipment of the HD 14i TT includes convenience features, such as the vibration-isolated operator’s platform and the 12 V socket. However, the vandal-proof cover on the dashboard, the electronic battery isolation switch, or the pressure water sprinkling system is part of the basic package. Added to this is a large selection of options, including a driver’s seat with seat heating, the ROPS cab, and the automatic engine stop function guarantees economical and environmentally friendly operation.

Extremely straightforward operation

As part of the HD CompactLine, the HD 14i TT pneumatic-tyre roller is extremely easy and safe to operate from the offset without the need for any period of familiarisation. Simple access, minimal controls, and unique, language-neutral, logically arranged symbols prevent operating errors.

HAMM pneumatic-tire rollers for large jobs too

In addition to the HD 14i TT, HAMM’s range includes other pneumatic-tire rollers: The HP 180i (working weight 8–18 t) and the HP 280i (working weight 10–28 t). With a working width of 2084 mm, both are suitable for larger projects. The range of potential applications extends from soil stabilization and cold recycling, through to landscape gardening as well as final compaction and surface sealing in asphalt construction. They also fulfill the exhaust gas directives in accordance with EU Stage V/EPA Tier 4. One of the technical highlights of this “big sister” is the intelligent ballasting concept for optimum compaction results. Furthermore, characteristics such as the extremely versatile water-sprinkling system with innovative additive supply and the modern travel drive guarantee high quality and productivity.
