For the Chinese market, HAMM offers ten new models between 1,6 and 5 t: HD 18 VV, HD 20 VV, HD 30 VV, HD 30 VT, HD 35 VV, HD 35 VT, HD 35 VO, HD 50 VV, HD 50 VT and HD 50 VO. They all meet the emission standard MEE IV and are manufactured in the Wirtgen Group factory in Langfang/China. The range of drum widths reaches from 0,8 m to 1,38 m, and all technical features have been tailored to meet the requirements of the national market. Regarding compaction technology, there are models with two vibration drums (VV), models with one vibration and one oscillation drum (VO) as well as models with one vibration drum and one set of tyres (VT).
Wasp waist leads to good visibility
Due to the intelligent design of the engine hood, the area in front of the machine is always clearly visible. Moreover, the typical HAMM wasp waist design offers an unobstructed view of the drums and immediate surroundings to the drivers.
Homogeneous weight distribution
The 3-point articulation is one of the key factors for compaction quality. It ensures not only a uniform weight distribution over both axles, but also enables a very small turning radius along with exceptional driving comfort. In addition, thanks to the low centre of gravity in combination with the 3-point articulation, the rollers of the HD CompactLine have great resistance to tipping, too, even in tight corners.
Compaction force meets large drum diameters
The rollers of the HD CompactLine Series have a high static linear load and generate very large centrifugal forces. Both contribute to the high compaction power. In addition, the drums have large diameters. This helps to actively prevent the formation of fissures and bulges while promoting high compaction quality. When it comes to compaction along walls and kerbs, the HD CompactLine rollers are able to do a complete job being easy to handle in every position. This is possible, because the drums of the HD 18 VV and HD 20 VV are offset by 72 mm and 70 mm as standard. Optionally, a variant without offset is available for these two models. Both models also have a “clear side”. That means, the drums are suspended only on one side in a way that no component protrudes beyond the working width on either side. As a result, they can compact right alongside walls and other boundaries. The drums of HD 30 and HD 50 can be offset by up to 50 mm. All models come with foldable scrapers as standard.
