The suction boom is an accessory designed and sized to be incorporated into machines equipped with tanks to sludge suck (or similar fluids) from road gullies. The suction is created by vacuum inside the tank (e.g. drainage vehicles). The suction boom allows simplifying the operator's work by nearing the hose to the workplace.
The suction boom is normally installed on the upper part of the tank. It essentially consists of a hydraulically or electrically operated telescopic arm (which houses a suction pipe) connected to one end of the sludge tank.
The figure shows a schematic view of the suction boom (suction boom DN100 – DN125 – DN150; the same considerations apply for the DN200 version), highlighting the main components.
The suction boom is designed to withstand (relative) vacuum/pressure -1 / +4 bar. The solenoid valve coils have a consumption of approximately 1 A in the 24V version and approximately 2 A in the 12V versions.
The suction boom is designed to allow for a maximum rotation angle of 300° and a maximum telescopic extension of 1350mm.
Available versions
The suction boom is available in various versions that are distinguished by the following parameters:
- Suction hose connection manifold diameter available in the DN100, DN125, DN150 and DN200 versions;
- Type of activation of the suction line shutter valve, available in the hydraulic and pneumatic versions;
- Type of power supply, available in the 12 V and 24 V versions.
The following table shows the available suction boom models and relative identification code.


1. The body and the slewing ring are made of cast iron.
2. The telescopic arm is made of galvanised S235JR mild steel to ensure its high resistance against weather agents.
3. The hose guide rollers are made of plastic material. The parts of the suction boom in contact with the transported material (suction boom conveyor, suction boom plate) are made of GS 500 cast iron; whereas the shutter valve is made Of NBR.
