Developed for and by railway companies
Even with a filled water tank, the operating weight is only 1,500 kg, which makes the soil suction unit suitable for machines from 13 tonnes upwards.
A standard 1.5 metre rubber suction hose is supplied, with a serrated edge at the bottom. Other lengths or materials are possible.
Easy to connect to your machine, no electrical connection required.

Soil suction unit, How it works
The soil suction unit uses airflow to suck up the material. A movable suction hose – both hammering and rotating – carries the material with the airflow to the reservoir. Once in the reservoir, the material sinks to the bottom due to gravity. The airflow continues through the sieve, which is at the top of the reservoir. The airflow continues through the impeller and the impeller housing, where it continues its way out. The exhaust has a coarse filter, with a fine filter installed around this.
Sprinkler installation soil suction unit
A sprinkler installation is provided for dry materials. Water is added to the nozzle in fine droplets to ensure that it is well mixed in the airflow. By spraying the soil with water, considerable dust reduction is achieved. The volume of airflow is pulled through a centrifugal fan. A hydraulic motor drives the centrifugal fan.
Control soil suction unit
- 1x Standard hammer circuit (single acting) up to 115 litres maximum at 300 bar. For operating the ventilator + up and down movement of the squeegee + optional rotation of the squeegee. This is possible by changing the ball valves on the suction box itself.
- 1x Rotation circuit (double acting) à 20-30 litres at maximum 180 bar.
- Standard equipped with high pressure water system (250 bar).
- The top of the container is fitted with a flat plate with HM1000 hole pattern. Because of its construction, the soil dredger can easily be used in places with little space, for example under a tree that needs to be moved, or in a tunnel.
- Optionally, a rotating suction nozzle is available.
