The Wirtgen SP 15i Slipform Paver is used for the paving of concrete profiles in diverse geometries and cross-sections.  These include curbs, water gutters, canals, sewers, cable ducts and reinforced traffic barriers.

Packaging

The SP 15i comes in a Wirtgen branded box, and it is held within two expanded polystyrene trays, and wrapped in soft paper.

There were no defects or missing parts on the review model although one part had to be re-fixed out of the box.

There is no information provided about the real machine.  A small leaflet in English and German describes how the various small parts are fitted to the model which only takes a few minutes.  Not all features are described.

Detail

The tracks are yellow rubber and resemble those of the real machine.  They are mounted on smooth cylinder pistons which are contained within detailed hydraulic cylinders although there are no hydraulic lines modelled.

The mould is a nicely formed part, mainly in metal, and the trimmer is also detailed with milling wheels and an auger.

The conveyor is a metal part with a hopper with wear protection and a metal auger.  A metal chute discharges into the mould.

Details on the body are excellent with finely reproduced door hinges and there are textured surfaces on the engine cover. 

The operator's platform has a textured floor and metal hand rails.  The control panels are particularly finely detailed.  An umbrella can be mounted and there are spotlights on top of the legs.

Features

The rubber tracks are stiff to roll, and the track assembly pivots on each piston.  Each leg can be extended by pulling it down and it is stiff enough to hold the model up well.  The two front legs can be adjusted for transverse position.  At the back the rear leg is also adjustable sideways.

The concrete feed conveyor can be positioned to discharge on either the right or left side of the machine although it is a little fiddly to move it across.

Underneath, the trimmer has a rotating milling head and auger screw, and it can also be pulled out to extend its reach.  It also pulls down significantly for when the machine is standing high on its legs. 

The mould can be positioned on either side of the machine, and also adjusted sideways for position.

The operator's station can have the control pad positioned on either side and there is also an optional cover which can be fitted. 

The umbrella can be added or removed as desired.

The model can be posed as a transport load.  The mould and umbrella can be removed, and the engine exhaust pipe folds to reduce the headroom.

Quality

This is a very high quality little model with plastic used appropriately to enhance the detail.. 

The paintwork and graphics are very good too.

Price

It is good value.

Overall

The Wirtgen SP 15i is a finely detailed model with an excellent array of features.  NZG have done a very good job with it and it is an excellent model.
