Hitachi ZX870 LCH-3 with Multi-Quick Processor Video
The Hitachi box with collector card on the outside.
The ZX870 with the processor.
Cab interior is convincing.
This is a large machine.
Detail around the body is first class. .  Excellent door handles on the panels.
Hydraulic lines on the boom top are really good.
The DemaLink system allows the processor's jaws to be changed without removing the rotator and hydraulic cylinder.
Very good detailing on the processor.
The Hitachi ZAXIS 870 3 series machines are large hydraulic excavators and the version modelled here has an operating weight of around 85 tonnes.  It has an 8.4m boom and is fitted with a Demarec Multi-Quick Processor.


The Hitachi branded box contains the model held within expanded polystyrene trays.  A collector card is held in a wallet on the outside of the box and this provides the unique number of the model within the production run.  There were no defects or missing parts on the review model.

Unfortunately there is no information provided about the real machine and nothing which describes the features of the model. 


It is immediately clear that this is a highly detailed model.

The underside of the track frame is plain but the underside of the body is very good with various plates and bolt heads present within the casting.  The track frames are nice pieces with tiny graphics and working rollers on the top, but not the bottom.  The tracks are metal and high quality with very good bolt and grouser details.

The body is excellent and is probably the best yet seen on an excavator of this size.  Alongside the cab the walkway has a finely perforated surface although it cannot be removed for when the machine is being transported.  The cab has a metal grab rail and very well made falling object protection.  Inside the controls and pedals are fully modelled, and the seat is blue with the Hitachi name which mirrors the original machine.

Behind the cab the details are first class.  Panels are detailed within the casting with individual rivets shown, and inside the body there are silver panel handles and clasps which are really great details.  Various doors can be opened and these let the superbly detailed engine be seen.  The cooling fan can be seen behind a grille and appears very realistic.  Various metal grab rails and hand rails adorn the body and they have the fixings to the body clearly detailed which is outstanding.

The counterweight has detail within the casting and warning signs applied.  The lifting eyes are also useable so it could be posed being lifted if desired.  It is however difficult to fit completely flush to the back of the excavator so from some angles a slight gap can be seen.

The boom has individually fixed metal hydraulic lines and they are excellent.  Plastic lines join them to the cylinder.  The cylinder jackets are plastic as usual, but the colour match is very good, although with the rest of the detailing being so good metal cylinder jackets would have been a fitting inclusion.  The pinned connections to the main lift cylinders and the arm look right.

The arm has some small graphics and the connection to the Demarec tool is made with bolts.  It is very well made and looks authentic.


The tracks roll well on the frames and the idler is spring loaded so removing the tracks is straightforward.

A pair of doors open on the cab side of the body, and there is an opening cowl which gives access to the very detailed engine.

The model rotates well and the range of movement of the boom and arm is very good, and the cylinders are stiff enough to hold any pose.

At the rear the counterweight can be removed although it is fitted very firmly so needs to be gently prised off taking care not to scratch the paint.  This makes it a more realistic haulage load but the tracks cannot be retracted so it sits wide on most vehicles.

The Multi-Quick Processor can be removed by unscrewing the two nuts and bolts and these are a much nicer connection than the simple pins often used.  The tool rotates, and the jaws open and close and can also be separated by sliding out two pins.


WSI have produced a very high quality model with excellent details and the applied graphics really add to the realism.  The quality of the paint finish is very high.

As the model is so highly detailed care is needed in handling the model so as not to apply undue pressure on delicate parts.


This model offers really good value for the quality and details provided.


This version of the Hitachi ZX870 is every bit as good as the others and WSI have done a great job with it.  It is good to see an addition to the growing range of demolition machinery modelled.  The model is outstanding.


The model appeared in October 2010.  Two other versions were produced, one with a digging bucket and the other with a heavy Demarec DRS-75 Shear.  Each of the three versions was made in a run of 1000 models.
