HC series: A new generation of compactors for earthworks
August 17, 2022 By HAMM
Powerful and “digital-ready”: HAMM is attending bauma 2022, where they will present the HC series – a new generation of earthwork rollers for all markets. The compactors achieve a high level of compaction power while simultaneously achieving a reduction in CO2 emissions. The communication capabilities are new: All models in the HC series are “digital-ready” since they can be equipped with various interfaces for the digital construction site.
One platform for all markets
The manufacturer is bringing together the two previous compactor series from HAMM – the 3000 series (Tier 3) and the H series (EPA Tier 4/EU Stage V) – with the HC series on one platform together with models with an operating weight of 11–25 t (24251-55115,6 lbs). The diesel engines comply with the regional requirements, and their power varies between 85 and 160 kW, depending on the weight. On all models, the drum width is 2140 mm (84,3 in). In addition to the previously known sales variants, in future, there will be CR machines with reinforced components for applications on difficult terrain and special equipment for applications on rocky ground.
The HC series is recognizable from the new, athletic design and the view channel in the engine hood. A new frame concept also guarantees increased tank volume; in particular, in future, the heavy compactors will be delivered to the construction site with a 336 l (88,8 Gal) fuel tank.
Impressive compaction parameters
In comparison to the predecessor models, HAMM has increased the compaction power. The manufacturer has increased the centrifugal force by up to 15%; and the static linear load is as high as 80.6 kg/cm (451,6 lbs/in). There are even innovations when it comes to the steering: A new cast articulated joint with articulated joint lock allows for a greater steering and swing angle with improved kinematics. Thanks to the optimized weight distribution in combination with the Traction Control, the gradeability has also been further improved. Furthermore, the front vehicle and the scraper have been redesigned. This has resulted in significantly increased clearance on the drum, meaning that no material can accumulate there, which eliminates cleaning work.
