Detail
The small metal tracks are finely detailed, and they are mounted on small frames
with the drive sprockets having detailed faces. Hydraulic hoses run to the
frames from the body.
Underneath the model the mining drum is large with
finely crafted silver tipped metal picks. The side
skirts are metal and there are rubber flaps on the rear
skirt.
The large cab area lights and mirrors, and the interior
is very good and includes a trainer's seat and a computer
console.
On one side two large exhaust pipes have realistic holes and
various panels are detailed. At the rear two large
cooling fans are impressively modelled and they sit
behind a fine mesh grille.
Metal handrails surround the top of the body, and there
are excellent etched footways. A detailed engine
can be seen in the main well, and at the rear the
steering mechanism for the rear legs.
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 track frame can be steered.
The mining drum rotates and there is an
adjustable side skirt
on each side and a movable skirt at the rear.
The access stair at the front can be lowered and raised.
A side panel can be opened and hydraulic hoses are
visible.

optional ballast weights to be can be added.
