NZG Liebherr HS 8100 HD Crawler Crane by Cranes Etc TV

This model by NZG of the Liebherr HS 8100 HD crawler crane supersedes the earlier 855 version. Opening up the box there’s the usual
pair of expanded polystyrene trays and there is also another small Liebherr branded
box and that contains a slurry wall grab. A couple of instruction sheets complete
the contents. One of the sheets describes the reeving of the A-frame but it’s all a bit
unnecessary as we will see later, and a second instruction sheet is long and
comprehensive, and includes the various configurations of the model. It is all pictorial and easy enough to
follow. Perhaps the only thing that’s missing
that would be useful is a parts list. But overall it is very good unless you
don’t like very long pieces of paper. Let’s move on to the model and it’s very
similarly packed to the previous 885 model and its factory sealed in there are lots
of parts in the top tray. If we cut a bit more factory sealing we
can see what’s in the bottom. If we take off the top tray we see the
crane but don’t worry it’s not an unusual
upside-down design and here’s the proof of that when it’s outside the box. It’s interesting that there’s some
additional packaging on the A-frame and that’s because NZG has been
helpful and the A-frame has in fact been reeved in the factory. So that is one less job to do but you do
need to make sure that you don’t bounce the ropes off the pulleys as you handle the crane. Usually the model has a box within the
box and here is the slurry wall grab and it is in its own Liebherr box and has the
NZG model number of 9451. As usual there are a couple of trays and if we lift
off the lid the grab sits inside surrounded by
soft paper. For the basic assembly we will build the crane and add on the slurry wall
grab. So to start with we begin with the
counterweight which consists of a number of separate parts and each of the small
blocks is skewered together by U shaped pins which helps to keep the counterweight
together. It’s a good idea and it keeps the blocks
together and stops them flying everywhere if you blow your nose nearby. The real crane is able to assemble the counterweight
itself when in erection mode, and once it’s already the crane backs up
to the counter weight. The chains that are hanging down are
connected and then the counterweight is lifted by hydraulics on the crane. Assembling the boom sections is just the
normal process. They go together well and they are secured by tiny nuts and
bolts, and here we see old fat fingers using
the special tools that are provided to do up the nuts and bolts. The one thing you don’t want to do though
is to drop these tiny parts on the floor because then you’ll be scrambling around
with a magnifying glass trying to find them. Still, the good news is the tools work
well and when you tighten up the connections
they are nice and secure. So here is the boom assembled and the
pendants are very nice with their wire connections, and by turning the key on the winch drum we
can raise the boom. There are two ropes to fit to the slurry
grab and here we fitted a couple of pendant shackles to make a nicer
connection. With the grab attached the model is complete in its first
configuration. The crawler tracks are metal and they are mounted on nicely detailed frames and the high standard of detailing continues on the cab both inside and outside. The body panels are nicely decorated and
they handrails and ladder are made of soft plastic, and at the back the counterweight
blocks look convincing. The boom sections are made of metal as are all of
the pulleys. The slurry wall grab is also a high quality
metal part and all of the connection pins are discrete. For the dragline
configuration there is a metal fairlead arrangement at the boom foot and the
dragline bucket is also a high-quality metal part. In crane mode there is an auxiliary jib which
sits at the top of the boom and there are a nice pair of metal hooks. For our first look at the features we will
strip down the crane to use as transport loads, and it’s good that there is enough rope on the luffing drum to fully lower the A-frame. That doesn’t leave a fully realistic
transport load because of the handrails, and also you can’t fold up the walkways
on the side of the body. The track frames are nice because they can be narrow for transport, or you widen them for when the crane is working, but another feature on
this model is that the tracks are removable. But to do that you start off by taking
off the plastic covers which cover the screws. Then you get the screwdriver to undo the
two screws which hold the track frames on. Only one word of warning is that whilst it is easy to
take the track frames off, putting them back on is rather more awkward. There are jacks on the crane which can
be lowered by unscrewing but whilst we’ve got the crawler tracks
off, let’s take a closer look at them, and to begin with they can be rolled easily
enough by hand. They are spring loaded for tension and it’s nice to also have working rollers. With the tracks off we can make some
nice transport loads. The grab works well, and by working the winches on
the crane you can open and close it and in that respect it’s just like the real
slurry wall grab. Now let’s take a look at a couple of
other features on the crane body. To work the main winches you need to
open a panel so you have to take off a ladder, and once you can get inside you use a
key to operate the winches which both have positive brakes. The same system
also applies to the luffing winch which also has a nice positive brake. To configure the model as a dragline you
need to change the pulleys at the top and you also need to fit the fairlead at the
the boom foot. The purpose of this is on the real crane is to reduce rope wear as the bucket swings about and here you can see how the bucket is
fitted with a rope running to the fairlead. There’s no proper way to fit the rope
from the fairlead to the bucket chain but as a tip you can use one of the
small brass bolts and screw it in and secure the rope. Once you are all set up, you can work the bucket realistically from a tipping mode and wind it into a dragging mode. Another mode for the model is as a crane. There is an auxiliary jib which goes on the boom top and then you can add on the two hooks that are provided. This is a nice update to the previous 855 model and its
flexibility has been further increased by the addition of the slurry wall grab.
The standard of the detailing and the features on the model are very good, so
if you want a flexible high-quality crawler crane model, this one is
