Vacuum unit AKNS-3,5 GAS NEXT

Tanker truck aerial platforms AKNS-3.5-base GAS-С41R13 “Lawn-NEXT” intended for the collection of municipal waste from the earth’s surface, from pits and buried tanks, cleaning of wells, storm and sewer systems, septic tanks of silt and transportation of the collected mass to the places of disposal.

Tankers, ACNS-3,5 can be made in all climatic versions.

The car is equipped with a cargo console with electric winch with remote control for lifting/lowering the spare wheel, and also used to raise manholes sewer manholes to facilitate the work of the operator.

The components of the tank:

  • tank (circular cross section, 09G2S),
  • a vacuum pump (DA-505, PNR-122, PVT-200 PVT-400, VC-6M2 or BP-8/3),
  • electrical equipment
  • fire-fighting equipment (fire extinguishers, sand box),
  • measurement tools (pressure-vacuum gauge).

Variants:

  • The waist fastening of the tank to the chassis instead of technological support.
  • Technological quick-release hatch for tank cleaning.
  • Extra filler neck in the rear of the tank (with certificate of calibration).
  • Heated gate valves from the exhaust system of the internal combustion engine.
  • The lighting system of the working area in four positions.
  • Tool box on the rear chassis frame.

Technical features of vacuum unit

The tanker, ACNS-3,5 — tank mounted on the chassis of “GAZ NEXT”.

The tank is a welded structure with two bottoms and sides of a round shape.

At the bottom rear of the tank welded pipe flange, on which hinged bolts emergency hatch. It consists of a cover, which is attached to the arm with the disc, when turning the handle is the opening or closing of the hatch. The seal achieved by the gaskets. To the front door with a captive nut attached to the sleeve that consists of pressure-suction hose DN100 mm, cap nut for the connection with hatch, gasket and tip.

The compressor is assigned to create a vacuum in the tank when filling and the pressure during the discharge. System vacuum systems include: vacuum pump, oil separator, moisture separator, piping system with ball valves.

The pump drive is from the engine gear through the propeller shaft.

Tank base made of supports on the subframe and is designed for mounting to the chassis. A support joined to the metal cradles that are attached to the frame rails, truck step ladders. To save from collapse under the pillars in the cradle is a metal stand and ribs. Under the supports of the tank are rubber shock absorbers.

Elektrobudowa laid in the hose, all connections are tight, the instruments are made explosion-proof.

On the tanker provides for the warning “Flammable”. To the rear there is a circuit of camp ground. 200 mm the chain must touch the road.

Improvements under the transportation of dangerous goods:

  • the orange tank that says “FLAMMABLE”,
  • the transfer of the silencer,
  • spark arrestor,
  • shielded wiring,
  • coil grounding
  • the grounding circuit
  • protection of fuel tanks
  • rear protective device
  • flashing beacons orange – 2 PCs,
  • fire extinguishers – 2 pieces,
  • a box for sand,
  • box felt,
  • retro-reflective markings
  • mount information signs hazard class.
