HAMM has a host of innovations to show at Bauma 2016: the DV+ series pivot-steered tandem rollers are the highlight for asphalt paving construction. They utilize the new Easy Drive operating concept that will be presented in detail at Bauma. The HD+ series tandem rollers and H series compactors will also be equipped with Easy Drive in the future. For the earthmoving sector, Hamm is presenting the ultra-small H 5i and H 7i compactors. The extensive package of innovations is rounded off with the 3000 series – these classic earthmoving machines have been updated in some areas to meet the specific requirements of the Tier 2 and Tier 3 markets. In the rubber-wheeled rollers segment, the newcomer is the GRW 180i with a maximum weight of 18 t. Hamm will also feature innovations for the measurement and documentation technology area. WITOS HCQ will allow data to be transferred directly from and to rollers in real time.
The tasks to be carried out in road construction and earthmoving are becoming ever more complex. At the same time, different climatic zones, locally proven construction methods and materials, as well as legislation, are resulting in marked regional differences in equipment requirements. Hamm is ready for these challenges and is presenting the industry with an extremely diverse product programme tailored to the specific characteristics of the regional markets all around the world.
The key HAMM innovations on display at Bauma 2016 will be:
- DV+ series tandem rollers: the premium class for asphalt compaction
- Easy Drive operating concept: now available on three machine series
- H CompactLine series compactors: compact earthmoving
- GRW 180i rubber-wheeled rollers: new in the class up to 18 t
- 3000 series compactors: tried and tested classics
- WITOS HCQ: optimized process for compaction monitoring
DV+ series tandem rollers: the premium class for asphalt compaction
All variants of the pivot-steered 7 or 9 t rollers will be on show at Bauma 2016, with double vibration (VV), a vibration and an oscillation drum (VO), and as a combi roller (VT). All models offer a fully glazed panoramic cab with optimum visibility. The driver has a good overview of the drum edges, the edge pressing and cutting assembly, and the construction site at all times. In addition, viewing panes in the cab floor ensure that the driver can see the rollers or wheels throughout, and in the cab, the Easy Drive operating concept provides top-class ergonomics and comfort.
With their modern engines (DV+ 90i: 75 kW, Tier 4i / Stage IIIB and DV+ 70i: 54.6 kW, Tier 4 / Stage IIIB) and highly effective diesel particulate filters (DPFs), the new rollers satisfy the stringent exhaust gas requirements of the most restrictive markets in Europe and North America. The large water and diesel tanks enable high productivity over long work intervals. The filling process is extremely user-friendly, thanks especially to a safe and very fast water-filling system that operates from ground level via a pressurized supply as standard.
Easy Drive operating concept: now available on three machine series
For modern, easy-to-learn and continually safe operation of the rollers, Hamm has developed the new “Easy Drive” operating concept. It aids the driver with self-explanatory, logical user guidance. Its principal components are the clearly arranged instrument panel with steering wheel and a multi-function armrest with joystick and push-button switches. They are used to access the main functions. The Easy Drive system also includes a fully adjustable seat. Just like the steering column with the instrument panel, it can be individually adjusted so that drivers can quickly find a healthy and ergonomically sound sitting position.
Another special feature of Easy Drive is its operating structure. The wheel is used for steering. All other important functions are operated via a joystick and the multi-function armrest. The operation is designed to be entirely language-neutral. HAMM uses colour coding to achieve unambiguous assignment of the elements and a clear overview.
H CompactLine series compactors: compact earth-moving professionals
For the earth-moving sector, Hamm is bringing along the ultra-small H 5i (4.8 t) and H 7i (6.3 t) compactors from the H CompactLine to Munich. The specially designed series of compact machines satisfies the requirements in all areas by a wide margin. Powering the rollers is a Kubota engine with 54.6 kW output complying with Tier 4 / Stage IIIB.
A great deal of innovation has gone into the drive. The wheels are driven by wheel motors, with a special drive system distributing the torque to the front or rear axle, as required. This gives the compactors an exceptionally good climbing ability and generous ground clearance. The machines are also remarkably short, especially the H 7i: measuring approx. 4.40 m, it is the world’s shortest compactor in this weight class. The combination of compact design, three-point centre pivot assembly and short wheel base delivers very good driving and handling characteristics. This makes the compactors ideally suited for narrow and steep construction sites.
GRW 180i rubber-wheeled rollers: new in the class up to 18 t
Hamm also has something new in store for the rubber-wheeled roller equipment segment: the GRW 180i. Their dimensions and technical realization are identical to the GRW 280i. The difference lies in the engine the new models are powered by a 3.6 litre turbo-diesel from Deutz with a DOC system. It delivers 55.4 kW and stays below the limits for Tier 4 / Stage IIIB. The GRW 180i will be available in two versions the GRW 180i-10 (10 t basic weight) and the GRW 180i-12H (12 t basic weight). Both models can be ballasted up to 18 t.
The 3000 series compactors: tried and tested classics remain part of the programme
The 3000 series is a classic among compactors. The rollers are simple to operate and extremely versatile, have a high compaction power, enormous climbing ability and offer outstanding driving and handling characteristics thanks to the 3-point centre pivot assembly.
WITOS HCQ: optimized process for compaction monitoring
WITOS HCQ is complements the HCQ Navigator, Hamm’s versatile measurement and documentation system for compaction. In the basic version, the satellite-based system gathers all important compaction parameters and the progress of individual or multiple rollers during compaction. For this purpose, the HCQ Navigator generates a real-time “compaction map” allowing the areas which have already been adequately compacted and those which require further compaction to be identified at a glance. This enables the roller drivers to compact extremely efficiently and evenly.
The HCQ Navigator records the data during the process. Previously, this data would have been transferred on a USB stick to an office PC for data backup at the end of a day or project section. With WITOS HCQ, this process will be carried out via an online tool. Data is accessible from anywhere – even during compaction. For projects in the U.S., HAMM’s WITOS HCQ features the option of exporting the data in real time for the VETA analysis software.
The data can also be transferred in the opposite direction, planners can prepare construction site data offline and supply it via WITOS HCQ.
WITOS HCQ uses mobile phone technology for data communication. An impact- and vibration-protected SIM card is mounted in the panel PC for this purpose. The user acquires a mobile phone contract for the card through Hamm. The data transfer then takes place via the WITOS portal of the Wirtgen Group.
