The lighting works really well.

The Caterpillar AD60 weighs around 112 tonnes fully loaded, with the payload capacity being 60 tonnes.  It is a low headroom machine which is specially designed for underground operations.


The model comes in exemplary packaging.  There is an outer shipping carton which contains a tin which is protected by a nylon bag.  The tin is high quality and includes pictures and details about the real machine.

The review model had no missing parts or defects.

An instruction sheet for fitting the batteries to the model is included, as is a mini catalogue of the Diecast Masters range.


The underside has reasonable detailing with the transmission modelled.  The tyres have a good tread pattern and they are mounted on plastic wheels with a detailed outside face and hollow inner faces.

At the front the radiator grille is plastic, and the towing hitch has a painted pin.  The fire extinguishers look good, and the plastic engine block is visible from one side. The handrails and mirrors are plastic and they have a very good colour match.  The special exhaust system is also plastic. 

The cab windows have nice black seals and inside the cab there is the usual operator provided by Diecast Masters. 

Detail at the pivot point is very good and includes a movable locking bar for the steering.  Hoses and cables cross the pivot point.

The dump body is detailed well with useable lifting eyes in the sides and nice internal texturing.  Locking pins at the rear are highlighted with red paint and there are soft rubber mud flaps.  The two stage hydraulic rams have a plastic middle section which does not look right because of its grey colour rather than chrome.

A plastic insert is provided for the dump body which replicates a load, and it provides an interesting alternative way to pose the model.


It rolls very smoothly on the big wheels.  Steering across the pivot point has a shallow angle of perhaps only around 20.  Decent oscillation at the pivot point allows for rough terrain.

There are numerous handrails at the front which can be folded down for low headroom work.  There is also a folding access ladder.

The dump bed raises to a reasonable angle with the load floor at about 45, which is short of the real machine. 

The model features working lights, front and rear.  These are implemented very well.  There is a switch underneath which can be set to off, on and timer.  When switched to on, the lights can be switched on and off by pressing down on the cab roof.   The lights are LED and bright, and look really good.  The timer features automatic switch off after 20 seconds.

The load insert can be added, or left off.


It is a very good quality model with a quite high metal content.

The finish is very nice.


It is very good value having regard to the features.


Diecast Masters has taken another step forward with the implementation of lighting on this model.  It has been included in a thoughtful way, and the ability to use the cab roof as a switch is inspired.  Overall it is an excellent model.


The model first appeared in 2016.
