Easy Drive

Simple and intuitive operation is becoming increasingly important for state-of-the-art construction machinery. With Easy Drive, HAMM has, therefore, developed a standardised operating concept for tandem rollers (HD+ and DV+ series), compactors (H series) and pneumatic tyre rollers (HP series) that reduces complexity to a minimum and enables operators to react quickly and correctly in no time at all. Alongside its clear, intuitive, easy to learn operating concept, Easy Drive comprises a range of features that improve ergonomic, safety-related and service-related characteristics.

Split drum

When negotiating corners and roundabouts and when performing tight steering manoeuvres, attempting to perform compaction can lead to material being displaced and cracks forming on the surface. A split drum prevents this from occurring as the two halves rotate at different speeds. This minimises shear stress on the asphalt and avoids surface cracks and material being displaced. With the split oscillation drum, HAMM also offers a technology that combines the advantages of a split drum with those of oscillation. The result: Maximum compaction quality.

HAMMTRONIC

HAMMTRONIC is an electronic machine management system that monitors and controls all key machine functions, thereby increasing safety, economy and fuel savings. The opportunities offered by HAMMTRONIC include, for instance, automatic adjustment of the diesel engine speed to meet the power requirements of the individual drives. Moreover, HAMMTRONIC controls start-up and braking, and distributes the drive torques across the drum axis and back wheels in line with current operating data. HAMMTRONIC also controls the hydrostatic vibration drive and the various steering programmes (for DV+ series only), guaranteeing even, smooth movement of both drums.

Oscillation

In an oscillation drum, two eccentric shafts are fitted at a 180° angle to each other. Both unbalanced masses rotate synchronously, which causes the drum to perform a rapidly alternating forwards-backwards rotational movement. This results in the compaction energy being transmitted forwards and backwards tangentially into the ground below in the form of shear forces. The oscillation system developed by HAMM achieves compaction results that are scientifically proven to be more homogeneous and higher quality, leading to faster, more significant compaction increases. The scope of application is enormous.

Smart Compaction

In the Smart Compaction product range, HAMM offers various solutions for intelligent and simple compaction, compaction measurement and documentation. The focus here is on digital interfaces between the driver and the machine as well as various assistants. The innovations offered here (such as Smart Doc) contribute significantly to meeting the increasing demands for high compaction quality in modern earthworks and road construction, and directly integrating the megatrends of digitalisation and resource conservation into daily construction site activity.
