|  Comment on this model.
The Wirtgen W 250i Cold Milling Machine weighs around 44 tonnes. It is used for removing carriageway surfacing in depths up to 350mm, and can mill to a width 2200mm.
Packaging
The model comes in a Wirtgen branded box and is enclosed between expanded polystyrene trays.
The review model had no missing parts. One graphic was slightly misaligned.
The model comes with a bag containing a couple of handrail parts which have to be fitted at the cab entry points, and a couple of headrests for the seats. Spare track links are also included. A small sheet is included which describes some of the features of the model pictorially, but not all are covered.
Surprisingly for a Wirtgen Group model, there is no information about the real machine.
Detail
The metal tracks are finely detailed with yellow highlighting of the pads, and red scrapers are detailed too. They are mounted on small frames and hydraulic hoses run to them from the body. Underneath the model the milling drum is large with finely crafted metal picks which are tipped with red paint. The side skirts are nicely modelled and the extraction conveyor has a rubber belt.
The engine cover has large see-through grilles on the top and the detailed twin engines can be seen underneath with many plastic parts. The main drive belt for the milling drum is also modelled in rubber. At the rear the exhaust pipes have holes and the detailing at the back is enhanced with lights and a video camera. Each side has control panels above the legs detailed with paint.
The cab area has non-slip flooring and twin excellent control consoles with a bank of computer screens. Thin hand rails look realistic and the windscreens front and rear are good.
Large mirrors are fixed to the front of the machine and substantial hoses for the vacuum system run to the conveyor.
The conveyor structure is restrained in height by twin cylinders with realistic thin support cables. It is metal with a grille underneath and a rubber belt inside which is realistically textured.
Features
Each track unit has tracks which are stiff, but can be rotated by hand. They are mounted on pivots at the end of legs which are extendible to adjust the height of the machine. Each pair of tracks has linked steering.
The milling drum rotates and there is an adjustable side skirt on each side and a moving scraper plate at the rear.
The cab roof can be lowered to reduce the transport headroom and the seats have removable headrests to avoid the rear windscreen clashing.
The main engine compartment cover can be raised but it does not pose in an open position. Side panels can be opened.
The conveyor can be folded to reduce the transport length. It can be raised and lowered and also swung from to each side by a reasonable angle.
Quality
This is a high quality model with limited use of plastic.
The paint and graphics are very good.
Price
It is reasonable value for the size and quality offered.
Overall
This is a highly functional model by NZG, and it is matched with very good detailing too. It poses well with other models.
