 Comment on this model.
The Sennebogen 690 HD is a heavy duty
cycle machine designed for repetitive stressful
loadings. It has a 90 tonne capacity and a maximum
main boom length of 57.9m.
This model comes with a dragline attachment.
Packaging
It comes in a rather large branded box because the model
is fully assembled and reeved. Releasing the 690HD
from the packaging is a struggle as it is secured to the
polystyrene trays with numerous tightly wound ties.
The review model had no defects
or missing parts.
A few technical details of the real machine are included
on the box and a simple pictorial instruction sheet with photos
describes the main features of the model.
Detail
The metal tracks are good with snap-fit links which were
tight enough on the review model. They are mounted
on decent track frames with no moving rollers but there
are small graphics and steps.
The cab is plastic with a mirror and slightly fat grab
rails. There is a plastic step plate outside and the
internal detail is good. The body has a very good
paint finish with small graphics and panel handles that look realistic.
Flexible plastic handrails surround the roof and the
walking areas have an extremely fine textured surface.
At the rear the counterweights are solid blocks detailed with sharp
graphics applied. The chains are a little too
bright in terms of their silvered finish and the
pulleys for the boom luffing gear are separate brass
pieces.
The boom is metal with a plastic walkway inside the top
surface, and its structure is a reasonable
representation but the riveted connections at the top of
the boom foot do not look right. The two boom pendants
are an unusual pliable plastic and they are fixed in
length but the tension is equal.
At the boom head the large pulleys look fine but the
smaller brass ones would have been better painted to
match the rest of the crane.
The dragline bucket is large and the draining
perforations are also on the big side. It is all metal.
Features
The tracks roll well and the idlers on the frames
are spring loaded to maintain tension and removing the tracks is possible.
The track frames are also retractable, so they could be
set up in a narrow transport configuration.
The crane rotates well.
To gain access to the winches the whole of one side
panel is removable and this is certainly a better
solution than just having holes in the bodywork.
Inside the panel there are a couple of large keys and
these can be used to operate any of the three working
winches.
The boom luffing winch can be used to adjust the boom
angle although the boom cannot be fully raised near
vertical as the boom pendants are probably over
length.
There is no ability to reconfigure the boom as it is
permanently riveted in the delivered configuration.
Similarly the counterweight is fixed in place and not
made of individually separable parts although some
pieces can be unscrewed. However the
counterweight lift cylinders can be raised and lowered a
little.
The dragline bucket can be operated realistically.
Quality
There is a relatively higher amount of plastic on the model
but the colour match with other parts is very good.
The paintwork
has a good finish and the small graphics around the model are sharp.
Price
The model is reasonably priced overall.
Overall
This second version of the 690 HD mirrors the first in
that it can be taken out of the box and displayed with no assembly work. However
the compromise is that the model is not flexible as it
cannot be broken down for transport loads or used in
crane or other configurations. However it is a
good looking model, and is
recommended.
Footnotes
The model appeared in 2012. A version was also
made with a diaphragm
walling attachment.
