The Demag AC 700-9 is a 700 tonne class all terrain
crane. It has a main boom length of 60m, and a
maximum system length of 149m.
This version of the model is the
colours of Mammoet, the Dutch lifting and heavy haulage
specialist. It is the Collector's Edition of the
model.
It has Mammoet model number 410233.
Packaging
The model comes in high quality packaging with an outer
shipping carton enclosing a large Mammoet-branded box. The model parts are wrapped in soft
paper and held within
expanded polystyrene trays that are clipped together and
not taped.
The review model had no defects or missing parts.
This edition of the model comes with a book describing
the development of the real crane and it has many
excellent photos. There are some technical details
too although some more configuration and load chart
information would have been interesting too. The
build
manual for the model is very comprehensive with clear
steps describing the assembly and features, and only
reeving diagrams for the hook blocks are missing.
There is an excellent parts list.
Tools are supplied to assemble and operate the model,
and many of the bags of small parts are numbered making
it easier to follow the instructions.
The Collector's Edition also encloses an
engraved key chain fob with the unique number
within the production run. Also included is
a Mammoet AC 700 key chain.
Detail
The chassis is highly detailed with the transmission
and steering present although not all parts are
physically linked. The tyres are very good
with a fine tread pattern and they are mounted on nicely
detailed wheels.
The driving cab has a rope for hitching the hook whilst
travelling, and other details include a nice grille at
the front and a tiny graphic in the side windows. Door
mirrors, windscreen wipers and beacon lights complete
the external detail. The seat backs have a Terex
logo on them which may reflect the real crane that
Mammoet owns.
Behind the carrier cab the engine area has textured
surfaces and a nice mesh grille, and there is a
highlighted filler cap on a tank. The exhaust pipe
has a hole in it. The sides of the carrier have
highlighted bolt heads and tiny graphics to give an
authentic look, including a Mammoet fleet number.
The outrigger assemblies are robust and well made.
They are metal with chevrons and tiny graphics, and
circular metal pads can be clipped on for storage, or
used together with metal spreader plates which have
useable lifting lugs. The outrigger pistons have
smooth faces.
At the rear of the carrier the lights have plastic lenses,
and there is a realistic number plate.
The crane cab has a diamond plated access platform
outside with metal handrails and the interior detail is
excellent with a busy computer console. Small graphics enhance the
detailing around the crane.
The counterweight tray has useable lifting points and
the winch and luffing gear for the fly jib is reeved up
in the factory. The counterweight slabs also have
useable lifting points.
The main boom rams are excellent metal parts
with thin white lines. Detailing on the boom includes a
couple of spooling drums and access platforms, and the
graphics are high quality. Pendant bars for the
Sideways Super Lift (SSL) can be stored for transport. A
ladder can also be hung at the front.
The inner telescope sections have a
realistic profile with thin walls, and the overall boom
geometry is excellent. There is a Mammoet graphic
on the top boom section. At the boom head the
sheaves are metal, and painted white. Hoist rope
tying-off points are modelled.
The SSL is well made and is nearly all metal. Only
the hoist guide rope part seems a little awkward on the
model.
Two hook blocks are included, 3 sheaves and 7 sheaves, and
they are very good metal parts. Also included are sets
of lifting chains and these are welcome additions to a
crane model. They can be used particularly when
the crane is self-ballasting.
A Mammoet-branded load plate is also included.
This edition of the model also includes holders for
carrying various parts during transport. These are metal
frames and they are another welcome addition to a crane
model.
Features
The axles steer independently with the exception of axle
six which is fixed as per the real crane. The
achievable angles are very good. The crane can also be posed with crab
steering if required by raising axle six out of service
and this works well on the model. There is sprung
suspension on each axle.
Handrails can be added to the crane body when in working
mode.
The outriggers can be extended and pads lowered, with
the crane able to be supported wheels-free, and the outrigger
beams remain reasonably straight. The beams can be
locked in their folded out position.
The operator's cab can be rotated from the transport
position and raised to provide clearance when the crane
slews. It can also be tilted to a good angle.
The counterweight system can be fitted in various
configurations, including being mounted on the
carrier deck during self-assembly.
Raising the boom is easy as the locking mechanism on the
main boom rams is by means of using a supplied key
tightening screws and
this works very well.
Telescoping the boom is smooth and easy with a spring
clip to lock each boom section. It has locking
positions at 45%, 90% and 100%.
A key is used to operate the main winch and it has a
positive brake system. Access to the winch is
enabled by a removable panel held in place by magnets,
and this is a high quality solution to avoid unsightly
holes in the crane body.
The SSL works well with the SSL winches being
stiff enough to provide reasonable tension on the boom.
Foldable access platforms on the boom provide support
for the SSL top sheaves.
The crane can be displayed in a variety of transport
modes from the lightest configuration (no front
outriggers and no SSL), to fully loaded.
Various parts can be carried on the supplied trays on a
suitable truck.
Quality
This model is well made and high quality.
It is beautifully presented.
The paint finish is slightly thick in places but overall very good, and the
many small graphics are
sharp.
Price
It is good value, with the additions in the
Collector's Edition being worthwhile.
Overall
This is an excellent version of the Demag AC 700-9.
It looks great in Mammoet colours. The book and
carrying frames in the Collector's Edition are top
notch.
Footnotes
The model first appeared as a Collector's Edition in Mammoet
livery. The Collector's Edition in Demag
livery was released in December 2019. A standard
edition without the book and other parts was also
released. |
