Homogeneous distribution of concrete fed from the side

Side Feeder ISF 850

Recipe for success when paving concrete on a steel reinforcement

The strength requirements placed

on concrete pavements exposed

to extremely high loads can only

be met by inserting a steel re­

inforcement. Reinforcements con­

sist of steel mats or dowel bars laid

out ahead of the slipform paver.

In such cases, concrete delivery

is possible from the side only. For

precisely this special application,

Wirtgen has developed the

ISF 850 side feeder.

The ISF 850 travels over the steel

reinforcement ahead of the slip­

form paver while being charged

with concrete from the side via

trucks or semi­trailers. The ISF 850

then spreads the concrete evenly

across the entire working width.

… fast concrete delivery even with a previously laid

steel reinforcement.

The Wirtgen ISF 850 side feeder enables …

Depending on job site conditions,

the ISF 850 can be fed with con­

crete from the right or left machine

side.

The machine frame and spreading

auger are of modular design and

intended for paving moulds ranging

from 4.75 m to 9.50 m in width.

Operation of the ISF 850 is quite

easy ­ the tried­and­tested operat­

ing concept is identical to that of the

large Wirtgen slipform pavers.

Four separately hydraulically driven,

steerable track units ensure good

manoeuvrability and traction.

Reliable delivery of concrete

Even distribution of large amounts of concrete fed from the side

As trucks or semi­trailers keep

discharging concrete into the large

receiving hopper of the convey­

or unit, the conveyor transports

the material to the centre of the

concrete slab to be paved. The

ISF 850 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 finally places

the concrete at the specified width

and layer thickness together with

the previously laid steel reinforce­

ment.

Tried-and-tested machine technology

The conveyor unit is distinctive for its conveying capacity of up

to 200 m³ per hour.

The spreading auger can be relied on to distribute the concrete across the specified paving width.

In order to enable trucks or

semi­trailers to drive right up close

to the ISF 850 in restricted space

conditions, the conveyor unit can be

retracted and extended at the mere

push of a button.

Optimum concrete supply is en­

sured by the movable conveyor unit

and variably adjustable conveyor

speed.

The hydraulically telescoping main

frame can be widened by means

of modular extension elements to

allow working widths ranging from

4.75 m to 9.50 m.

The spreading auger and concrete

scraper can also be widened in line

with the working width of the ma­

chine frame by means of modular

extension elements.

Modular design

Ease of operation comes as a standard feature

The conveyor unit can be moved and the conveyor speed and direction adjusted via the separate control console.

The walk-through operator’s platform permits

a direct view of the entire work process.

No problem at all thanks to the

standardized operating concept:

handling of the ISF 850 side feeder

is easy for those familiar with

operating the large Wirtgen

slipform pavers.

Labelled in a language­neutral

manner, the clearly arranged but­

tons and switches on the control

panel are self­explanatory and

enable intuitive handling. In addi­

tion to that, the conveyor unit can

be operated via a separate control

console. The walk­through oper­

ator’s platform can be accessed

from both sides and offers an

optimal view of the entire spread­

ing process. Taken together, these

benefits even allow one­man

operation of the ISF 850.

One-man operation is an option

Operating principle of a paving train with ISF 850

The ISF 850 side feeder is gen­

erally used in combination with a

slipform paver and texture curing

machine.

The ISF 850 accepts the concrete

from a truck and spreads the ma­

terial evenly across the previously

laid steel reinforcement.

The slipform paver following

behind places the concrete at the

specifi ed width, compacting and

smoothing it at the same time.

In a fi nal step, the texture curing

machine creates a defi ned sur­

face texture and sprays a curing

compound on the freshly paved

concrete surface.
