The Liebherr 1750-9.1 mobile crane has a maximum capacity
of 800 tonnes at 3m radius, and has a 52m telescopic boom.
The crane can be configured with a
TY Guy boom support arrangement and this option is
possible with the model.
This model is in the colours of the Dutch heavy lifting
and transport specialist Mammoet.
Packaging
The model comes in a Mammoet-branded
box design with the model held within expanded polystyrene trays
which are held together with plastic clips. The parts
are wrapped.
There were no missing parts
or defects on the review model.
The model has an
excellent instruction manual. It
includes a parts list, and clear photos and English text
describe the model.
A Mammoet collector card is included which has a unique
serial number within the production run.
There is no information about the real crane.
Detail
The chassis is very highly detailed and it has fully replicated
transmission and suspension systems. It also
includes the central rear outrigger.
The tyres are very good with a fine tread pattern, and Michelin
branding moulded in the sidewalls. The wheels have
different hubs for driven and non-driven axles.
The carrier cab has beacon lights and stub
aerials on the roof and at the front there is a hitch
for tying a hook whilst travelling. There is a
number plate which is generic on this version of the
model. The door steps are textured and
the door handles are highlighted. Interior detailing
is high quality with barely legible Liebherr printed on the seat backs.
Behind the carrier cab the engine area is highly detailed
with tanks having filler caps and the inside of the side
faring having detail. Textured surfaces and the mesh
grille are excellent. The chrome exhaust looks
realistic also. Tiny graphics add detail
throughout, and at the rear of the carrier the lights
and grab handles add to the realistic look.
The outrigger pads have a working pinning mechanism
which allows the pads to be fixed in an offset way so
they are within the footprint of the crane when the
outrigger beams are retracted. The
pistons are smooth with the screw mechanism being
internal so they look realistic. Tiny graphics add to
the authentic look. Large metal spreader plates with
useable lifting points are also included with the model.
The profile of the outriggers under load is very good
and they are nice and straight. As the outrigger
beams are designed to be removable on the real crane it
would have been nice to have useable lifting eyes on the
beams on the model.
The crane cab has metal
handrails and an access stair outside, with a finely
textured walkway. There is also a silvered mirror
and window wipers. The interior detail is very
good.
Underneath the crane body the
toothed slewing ring is visible. The crane body also
has a high level of detailing with small graphics, metal handrails and ladders, and textured surfaces are
very nicely modelled. There is a hole in the side of
the body which is used to provide access for the key to
operate the winch drum, but in fact this replicates a
hole on the real machine.
Metal mesh work platforms are fixed when the crane is
working and these are high quality pieces.
The counterweight consists of a number of parts.
The base plate is complex as is the large power pack
assembly which is highly detailed. It includes two
winch drums and the luffing gear is already reeved out
of the box. The counterweight blocks are nicely
decorated including the weight being marked with
graphics, and have useable lifting
eyes. Securing plates sit on top of the
counterweight stacks.
The main boom rams are very nice metal parts with
complex hydraulic detailing at the bottom, and the boom
sections have very thin walls which provide a realistic
profile. Detailing on the lowest boom section
includes a spooling drum, and combined with the casting
details and paintwork the overall appearance is
convincing. The boom head is also very good with
fine detailing and silver metal pulleys which probably
would have looked better painted. A long safety hoist
cut-off chain and block hangs from the boom top and
there is a realistic tying-off point also.
Out of the box the boom end has a small part of the TY
guy system attached, but this can be easily unscrewed
and removed if the model is displayed without the TY
guy.
The TY Guying system for the telescopic boom is of heavy
construction and is metal except for the plastic hydraulic
cylinder jackets which look good because they have an
excellent colour match. Tiny graphics add detail
to the system and these even appear on the metal guy
rods which is an excellent detail.
Two metal hooks are supplied and they are excellent quality
with metal pulleys and working safety latches.
Another nice touch is that a lifting beam is also
included.
Features
All axles have sprung suspension which is connected to
form floating groups. Each axle also steers with
some very good steering angles being possible.
The
central rear outrigger can be lowered and this would be
used for erection of the crane on site if the rear
outrigger beams have been transported separately.
Handrails on the crane body can be folded up from the
transport mode. Two access ladders can be folded
down from the carrier deck.
The outrigger beams are detachable from the crane.
They can extended and the pads lowered, and feature
an excellent pad pinning feature with fine wire clips.
The range of downward travel on the pistons is adequate if the
spreader plates are used, and the model can just about be supported wheels-free.
The pistons cannot be fully retracted.
The operator's cab rotates from the transport position.
It lifts up and down to obtain clearance during rotation
of the crane, and can
also be tilted.
The crane rotates
very smoothly without rocking.
The counterweight system can be fitted in various configurations,
including being mounted on the carrier deck during self-assembly.
The blocks can be single or double stacked, with the
counterweight plate being configurable to suit.
The power pack has useable lifting jacks to enable the
counterweight to be connected and disconnected from the
crane body and this system works well.
Raising the boom is easy with the locking mechanism on
the main boom rams using a key to tighten grub screws
on the jacket tops.
Telescoping the boom is smooth and easy with a spring lock
to clip each boom section. It is possible to lock
each section at approximately 50%, 90% and 100% extension.
The
TY guy system can be displayed as a transport load with
a transport bar included to maintain the shape.
When in place the system performs well with each side tensioned
by using the key in the smoothly operating winches which
have a positive brake. A reasonable tension can be maintained
in the system but the push fit connection on the guy
rope system and guy rods would likely pop apart under high tension.
The key is also used to operate the main winch. It has
a push-in action with a positive brake, and it works
very well.
Different hook blocks can be reeved, and they each have
rotating hooks and working safety latches.
Quality
This is a high quality model which is made well, and the
parts fit together well too.
The paintwork and graphics are generally excellent.
Price
It is
very good value for a limited edition large crane model.
Overall
This is a great looking heavy crane model in Mammoet
colours. It is particularly impressive when
matched up with support trucks in the same colours.
Footnotes
The model prototype first appeared at the BAUMA
Exhibition in April 2019 and it became available in
February 2020.
