The Liebherr PR 776 Crawler Tractor
was the world's first in the 70 tonne class which was
hydrostatically powered. It is designed for mining and quarrying activities.
It was first introduced at the Bauma Exhibition in April
2016.
This updated version of the model was presented when the
PR 776 was made available to the US market in 2022.
Packaging
The model comes in a standard Liebherr box design with
the model held within two separate expanded polystyrene
trays and protected with clear plastic sheets.
There were
no missing parts or defects on the review model.
There is no information about the real machine
or model.
Detail
The undercarriage has detailing on the base plate and
includes the transverse linkage between the track
frames.
The track
frames are detailed and include pendulum mounted bottom
rollers which do not rotate. The metal track shoes have
the bolt heads indicated. The high drive sprocket
and idlers also
appear to be metal.
The cab is metal with thin metal
grab rails and plastic mirrors. Inside the cab,
detailing includes black controls and 'Liebherr' is printed on the
seat back.
Outside
the cab there are textured surfaces and perforated
grilles at the rear. Small graphics add detail.
There are two metal etched walkways which
look really good and have metal handrails. A metal
stairway is mounted on one side. Fire suppression
equipment is mounted on one side.
The engine compartment has perforated grilles on the top
and sides and there are more small graphics and metal
access platforms. The large front grille is also
perforated. The exhaust pipes have heat protection
covers and the inside of the ends are painted black.
At the rear there is a towing hitch which would be
useable with a pin. The 1 shank ripper is all
metal with the exception of the hydraulic ram jackets.
Connection pins are painted giving a realistic look, and
there are hydraulic hoses running to the ripper rams.
The ripper tooth is nicely cast.
At the front the U blade is cast well with wear
plates on the bottom edge and perforations on the top
edge, and a well defined structure behind. There
are hydraulic hoses running to the main blade lift rams,
and the plastic ram jackets have an excellent colour
match with the grey metal parts.
Features
The tracks are stiff to roll. They are tensioned by spring-loaded
front assemblies including the idler and first set of
rollers.
There is oscillation across the two linked track frames.
The front blade has a decent range of movement up and
down, and can be tilted side-to-side. It can also
be tilted forward a little. However the rams are stiff
to operate.
The ripper equipment can be raised and lowered
with the rams having a pleasant stiffness. The ripper tooth can
be set at a variety of heights.
The access stairway can be rotated into position.
Quality
This model has a very high metal content and is well
made.
The paintwork and graphics are very good.
Price
It is good value.
Overall
This is an updated version of the Liebherr PR 776
model with enhanced details and functionality. It
is an excellent large crawler tractor.
