MINIEXCAVATORS FOR MINING AND ALLUMINIUM INDUSTRIES
    
 
   

Cylindrical shaped tank made by corrosion and abrasion resistano carbon steel, 6 mm thick with dished heads (6 mm thick). It is electricallywelded and torsion free fixed on sub-frame.
 
It is tipped by a dual-action hydraulic cylinder placed in front of the tank.
Total capacity 10 m³ for sludge.
 
The full size rear door is hinged at the top, opened by 2 hydraulics double effect cylinders complete with a neoprene rubber seal to prevent leakage and nos. 2 manual wheels clamps for the locking.

 
N. 1 4” suction gate valve manual operated with in-let pipe and with quick ball-coupling.
N. 1 4” discharge gate valve manual operated and with quick ball-coupling.
N. 1 overflow valve of floating type.
N. 1 stainless steel float ball indicator to monitor the sludge load level.



Vacuum Truck: SUB-FRAME

The sub-frame between chassis frame and super structure is made by high quality steel including pump treverses drive.
 
It is fixed to the chassis frame by brakets, screws and longitudinal and transversal supporting plates according to the indications of the vehicle manufacturer.

 

Vacuum Truck: TRANSMISSION

The vacuum pump is driven by means of a gear box p.t.o. (Power Take Off) via a mechanical transmission.

 

Vacuum Truck: VACUUM SYSTEM

The system is made by:
 
N. 1 stainless steel ball float shut-off system, fitted inside the sludge compartement, to shut down the air flow to prevent overfilling.
N. 1 moisture trap between the tank and the vacuum pump.
N. 1 air filter.
n. 1 overpressure valve set at 0.5 bar.
n. 1 vacuum breaking system.
n. 1 no return valve.
n. 1 4 ways valve for vacuum and pressure.
