Proven, high-quality and well-engineered technical details and solutions make the new suction superstructure a real construction vehicle of the future.
The micromesh filter consists of a cartridge filter that is mounted in the front part of the collecting tank. The filter elements are cartridge filters of the BIA dust class M. During the tipping process, the filters are mechanically protected against lateral forces. The residual dust content amounts to <10 mg/m³ and is therefore within statutory provisions. Automatic cleaning is carried out with compressed air. To this end, the filters are exposed to short blasts of compressed air on the dust-free side. The adherent filter cake falls off downwards and is disposed of during the tipping process. The filter can be removed in two blocks from the container.
The internationally patented RSP air conveyance and separation system guarantees the highest level of gravity separation, the lowest filter load and as a result constantly high suction capacities. All essential particles are separated in the collecting chamber due to the air slowing down and swirling. Smaller particles (sands) are eliminated from the stream of air in the downstream separation chamber. Residual dusts that reach the filter are dried strongly. This enables the micromesh filters to be cleaned effectively. During tipping, the separation chamber and micromesh filters are also emptied along with the central collecting chamber.
The four different RSP hose carriers with additional expansion capabilities are equipped with the RSP clamp system. Thanks to the compatibility with different accessory parts, the most varied suction tasks are feasible. The four moveable joints and a reach of six metres enable convenient operation from a safe location. The suction hose is firmly guided from the cover right up to the suction crown and can therefore be placed exactly in the suction point. The fully hydraulically guided jointed hose carrier is the optimum solution for working well at distances between 0 and 6 metres. With a swivel range of 180°, the RSP joint hose carrier was especially adapted to the site conditions. This allows the machine also to work safely where space is limited.
It makes it possible to work from the optimum location. All movements of the boom, the emptying functions, suction mode, separate compressor mode, filter cleaning as well as traction motor start/stop can be controlled using it. The hose carriers are moved proportionally by deflecting the joy-sticks and therefore moved more delicately. A battery charger with replacement battery is installed in the cabin. Delivery also includes a second, identically designed transmitter as a replacement.
Thanks to the silence kit, noise nuisance is noticeably reduced. The kit contains the sound absorption on the underside of the container as well as the insulation of the side walls behind the container trim. Furthermore, there is an optimised sound absorbing unit for the fan housing. It is equipped with 50% stronger sound absorbing material than in the standard version and is closed and insulated completely at the bottom. The noise prevention package is only possible in conjunction with option M20 container side trim.
The installed fans are the main component of the suction excavator technology. The high-performance fans developed specially by RSP achieve maximum performance data and the longest service life. RSP relies on highly exact balance quality and optimum connection and start-up conditions because these determine substantially the service life of the fan. Our fans are started slowly using a clutch; this leads automatically to a much lower load on the drive motor and increases the service life.
The compressor is installed as standard in every machine, however, because it is not needed during the suction process, the compressed air supply is demand-controlled. Depending on requirements, compressor output of 3.0 - 4.5 m³/min is available. When designing your machine, the hydraulic system is designed completely individually for suction tasks depending on requirements.
With four container sizes altogether and the option to fit these with stainless steel wear plates, you have the perfect conditions for doing the job really well. The container size 4 m³ is developed especially for two-axle vehicles with an overall width of 2.30 m. This compact size and the tipping axis height of 2.10 m ensure the container can be emptied on smaller transport vehicles. The 6 m³ container is specially suited for a vehicle chassis with a short wheelbase. The 8 m³ container provides more loading volume and therefore the ability to work more effectively. It is the optimum size for all 3 and 4-axle chassis. This container is most frequently used for suction work in excavation projects. The 10 m³ container is designed for very special suction tasks, for example, in industrial facilities that require a larger container capacity.
The different holders for nozzle or hose extensions make safe transport possible. Fitting it to the vehicle rear end guarantees easy handling. The holders are delivered galvanized.
