Vibratory trench rollers, tandem rollers with vibration or oscillation drums, combination rollers in different weight classes or single drum soil compactors: at Wacker Neuson, you will find exactly the unit that you need for your project. Built-in operator comfort. All vehicles score with comfort features and plenty of freedom of movement in the operator’s cab. And the remote-controlled models protect the end user from dust, exhaust fumes and noise emissions.

Rd24, Rd27

Whether a tandem, combination or oscillation roller: with the 2.5 ton machines, Wacker Neuson has a large selection – and therefore the right machine for each of your requirements. In addition, the intuitive operation makes it easy for you to achieve perfect work results.

Rd40, Rd45

The rollers of the 4-ton class from Wacker Neuson take care of work particularly efficiently. Due to their high compaction force, the wide drums as well as the selection option of two vibration levels and two amplitudes, they provide the optimal performance for all requirements. These models are available as tandem roller, tandem roller with oscillation drum or combination roller.

Advantages of Tandem and Combination Rollers

The advantages of the tandem and combination rollers in detail. From the technical outfitting for the actual compaction work to the comfort features to the practical details for transport or maintenance: Here you can see what all models have in common. With the five compact tandem and combination drum rollers, we have the right solution for you for various gradients, requirements and spatial conditions. In addition, the operator's cab can be outfitted to meet your individual needs.

Three-Point Articulated Pendulum Joint

Uniform compaction and a high level of driving stability are the key advantages of the three-point articulated pendulum joint with which all tandem and combination rollers are equipped, except for the RD7. It leads to a uniform pressure distribution on the tires or the drums, in particular when turning curves. In addition, it improves the maneuverability and provides for maximum tipping safety and stability, even on uneven ground conditions, such as coarse gravel.

Tandem Roller

Tandem roller: Front and rear with vibration drums. The vibratory drum optimally vibrates the material to be compacted with quick successive vertical forces. The built-in eccentric weight provides for a quick rotation and you achieve an excellent compaction performance. Ideal for: All classic compaction work.

Combination Roller

Combination roller: Vibration drum in the front, tires in the rear. The combination roller is only equipped with one vibration drum. The rear axle consists of rubber tires for pressing on the asphalt. This creates particularly high quality and smooth surfaces. Ideal for: Asphalt compaction on sidewalks and bicycle tracks.

Oscillation Roller

Oscillation roller: Vibration drum in the front, oscillation drum in the rear. The oscillating movement is caused by a quickly changing forwards-reverse rotary movement of two masses in the drum. These forces are continuously directed into the ground in a targeted manner. At the same time, the vibration exposure is significantly lower than with a vibration drum. This also has a positive effect on the service life as well as the driving comfort of the machine. Ideal for: Compaction work in the inner city, near vibration-sensitive structures (e.g. bridges, residential buildings, historic buildings), on seams (hot on cold) and for minor repair work.

Larger Time Frame, Higher Compaction Performance

With oscillation, you can compact asphalt at lower material temperatures as well. Compared to compaction with vibration you have a larger time frame.

Single Drum Soil Compactors

The single drum soil compactors of the 5 and 7-ton class are ideal when it comes to quick compaction of large areas and gradeability. In rough ground conditions, they also prove themselves through their stable driving position and a large angle of slope.

Smooth Drum

Due to the low depth effect, the smooth drum is ideal for applications in sensitive areas, e.g. near vibration-sensitive structures like historic buildings or on soil under which tubes and utility lines run. In addition, smooth drums are ideal for: Non-cohesive or weakly cohesive soils, such as sand and gravel Surfaces that have already been processed with a cleated (sheepsfoot) drum roller.

Single Drum Soil Compactor

One single drum soil compactor, two types of compaction. All tandem and combination drum rollers compact through vibration, but the RC70vo offers you a special extra: you can choose between the vibration and oscillation operating modes.

Easy maintenance

All rollers are designed so that maintenance is taken care of with a few easy steps: this includes good access to the entire engine compartment as well as an easy exchange of the air cleaner. This saves time and money.

Compact – the compaction control

Compatec shows the degree of compaction of the ground. The maximum compaction is achieved once the number of displayed lights remains constant.

Strategically placed

Due to the low location below the central axis of the drums, the centrifugal forces are directly transferred into the ground: for a high compaction performance.

Cleated drum

The trapezoid-shaped pads of a cleated drum compact the ground through kneading and crushing. The further the compaction progress, the less the pads sink into the ground. The application areas of cleated drums are: Fine-grained soils with a high water content, incorporation of binding materials, such as lime or cement, into acidic ground Compaction of cohesive, less supportive moist ground, as well as friable soft stone (e.g. when building dams).

Rd7

The RD7 is the right choice if you need to cover a broad range of applications. The walk-behind, dual-vibration roller optimally compacts asphalt as well as granular material. High level of operator safety – the roller automatically stops via the emergency stop switch on the center pole in the event of dangers from obstacles. Protection against hand-arm vibrations due to the anti-vibrations in the center pole. Easy starting even in winter due to the special coupling/pump drive system. Optionally available with an electric starter or manual start. Water tank with 60 l capacity allows for longer work intervals without stopping to refuel.

High level of comfort for the operator

All rollers are equipped with a completely vibration-insulated operator's station by default. In this way, the operator is optimally protected against vibrations. Additional safety is provided by the steps for the convenient entry, large legroom and an operator's seat that can be individually adapted to weight and height.

Rd18

Compact and extremely maneuverable – the roller RD18 is ideal for applications with limited space, e.g. in the urban sector. Due to the drum offset, you have complete curb clearance on both sides. It features a small turning radius for easy maneuvering and allows for precise work along walls thanks to the drum offset of 56 mm. The roller can be quickly secured for transport, as the tie-downs are easy to access. Additionally, large and perfectly balanced tires ensure safe lifting of the roller. Intuitive operation is facilitated via the self-explanatory display, enabling operators to immediately begin working.

Practical central lifting point

The centrally located central lifting point allows for a horizontal raising and lowering of the machine. The roller is thus easily, quickly and safely offset.
