The
Tadano AC 7.450-1 is a 450 tonne class all terrain
crane. It has a main boom length of 80m.
Packaging
The model has high quality packaging with an outer
shipping carton enclosing a large Tadano-branded box.
The model parts are wrapped in soft paper and held
within expanded polystyrene trays that are clipped
together.
The review model had no defects or missing parts.
The build manual for the model has an excellent parts
list, and it is very comprehensive with clear
steps describing the assembly and features.
Tools are supplied to assemble and operate the model,
and the bags of small parts are numbered making
it easier to follow the instructions.
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
detailed wheels with different hubs on driven and
non-driven axles.
The driving cab has a chain for hitching the hook whilst
travelling. Door
mirrors, windscreen wipers and beacon lights complete
the external detail.
Behind the carrier cab the engine area has textured
surfaces and grilles, and various exhaust and other
components modelled.
The outrigger assemblies are metal with chevrons and tiny graphics, and
circular pads. Metal spreader plates are included and
they 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 towing hitch.
The crane cab has a diamond plated access platform
outside and the interior detail is excellent with a computer console.
Small warning graphics enhance the
detailing around the crane.
The counterweight tray has useable lifting points and
the winch for the luffing gear for the fly jib is wound
with rope. The counterweight slabs also have
useable lifting points.
The main boom ram has metal parts. Detailing on the
boom includes a spooling drum and the collars at the end
of each section are particularly good.
The inner telescope sections have a
realistic profile with thin walls, and the overall boom
geometry is excellent. At the boom head the
sheaves are metal, and painted white.
The SSL is well made and is nearly all metal.
One large hook block is included and it has three sheaves.
A Tadano-branded load plate is also included.
Features
The axles steer independently and reasonable angles are
possible. All steering modes of the real crane can
be realised. There is sprung
suspension on each axle.
Handrails can be added to the crane body and
counterweight tray when in working
mode.
The outrigger beams can be extended and pads lowered,
with the crane able to be supported wheels-free, and the
outrigger beams remain reasonably straight.
The operator's cab can be tilted to a good angle, and
there is a slide-out access platform.
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 ram is by means of using a key
to tighten grub screws and
this works very well.
Telescoping the boom is smooth and easy with a spring
clip to lock each boom section. They have locking
positions at 45%, 90% and 100%.
A key is used to operate the main winch and it has a
positive brake system. The hook on the hook block has a
full range of movement.
The SSL works well with the SSL winches being
ableh to provide reasonable tension on the boom.
Foldable access platforms on the SSL system provide work
platforms for tying off at the boom top during rigging.
The crane can be displayed in a couple of transport
modes, either with or without the SSL attached.
Quality
This model is well made and high quality.
The paint finish is very good, and the
many small graphics are
sharp.
Price
It is reasonable value for a large crane model.
Overall
IMC has produced a very nice model of
the AC 7.450-1. It is an excellent combination of
details and features, and will look attractive in
company colour schemes.
