Operating principle side feeder

The modern ISF 94 / ISF 94i - here`s how it works

  1. Conveyor unit

    Conveyor unit designed for high conveying capacity, comprising a large receiving hopper and conveyor for transport of the concrete to the centre of the slab to be paved.

  2. Height adjustment

    Hydraulic height adjustment of up to 1,000 mm by means of servo valves.

  3. Slab paving mould

    Slab paving moulds available for working widths ranging between 4.75 m and 9.50 m.

  4. Power unit

    High-powered, fuel-efficient diesel engine for operation in the optimum performance and torque ranges.

  5. Pivoting legs

    Four pivoting legs to adjust the track units to site conditions.

  6. Concrete spreading equipment

    Spreading auger for even distribution of the freshly delivered concrete.

  7. Telescoping machine frame

    Machine frame telescoping in transverse direction.

  10. Operator's platform

    Ergonomically designed, walkthrough operator’s platform for non-tiring, productive working.

The strength requirements placed on concrete pavements exposed to extremely high loads can only be met by inserting a steel reinforcement. Reinforcement consists of steel mats or dowel bars that are either laid ahead of or inserted by the slipform paver. In cases specifying a previously laid steel reinforcement, concrete delivery is possible from the side only. For precisely this special application, WIRTGEN has developed the ISF 94 / ISF 94i side feeder. The ISF 94 / ISF 94i side feeder is gen erally used in combination with a slipform paver and texture curing machine.

As trucks or semi-trailers keep discharging concrete into the large receiving hopper of the conveyor unit, the conveyor transports the material to the centre of the concrete slab to be paved. The ISF 94 / ISF 94i side feeder then spreads the freshly delivered concrete by means of the integrated spreading auger and, without compacting it, places it at a smaller width but larger thickness than the slipform paver following behind. The slipform paver places the concrete at the specified width and layer thickness together with the previously laid steel reinforcement. In a final step, the texture curing machine creates a defined surface texture and sprays a curing compound on the freshly paved concrete surface.
