Model review

LTM 11200-9.1 rigged with T7Y boom and Y-guying system. For this photo shooting I have extended only one boom section. Otherwise you wouldn’t have seen so much on these pictures.

Also with this T3Y- boom system the LTM 11200-9.1 model makes a great impression. For this picture I have disassembled the upper 4 boom sections. Here I recommend doing this very carefully. The internal locking mechanism is also spring loaded and you might loose this spring once you disconnect the boom parts.

Impressively the crane model shows its massive boom within the warm September sun during is photo shooting. All filigree screw connections can hardly bee recognized. The whole boom system can be adjusted in two different angles.

By having a look into the carrier’s cab you easily can imagine the huge space inside. Windscreen wipers, warning lights and mirrors also exist on the model.

Also on the huge 9-axle crane carrier, which has a weight of 108 metric tons in reality, the level of details is amazing. NZG surprises with individually steerable axles, which are all spring loaded! And this I really didn’t expect.

The crane during traveling: The crane cab shows to the front, while the boom cylinders are positioned to the backside. Even a license plate is indicated on the back and front side!

While traveling all handrails on the superstructure are disassembled to not exceed the maximum transport height. All railings I can easily place inside the appropriate holes.

A small ladder and a warning light exist on the backside of the crane carrier. Small hydraulic cylinders would move the fur massive outriggers. Even a small toolbox is fitted to one outrigger.

During its self-assembly the boom is supported by its outriggers. All of these are being brought into their assembly position and secured by a small pin. Afterwards I move the outrigger pads into a vertical position; a special locking mechanism ensures that these always stay stable.

All outrigger pads I expand and connect the four pads to the outriggers with four pins. Luckily NZG has placed the screw thread to the inside where you won’t see it. And this looks completely realistic as a hydraulic cylinder on the real crane. Hopefully we will find this nice feature also on possible future crane models.

Two massive bolts to the superstructure connect the heavy boom. You can also recognize railings and connection points for them. An auxiliary winch is also indicated on the model.

And with this all-new crane cab, Liebherr also breaks new ground: the cab is attached to a new boom system. The operator can easily access the cab direct and safely from the ground without using ladders. And this parallel kinematics is also well copied on the model: from 8 cm eye level or 4 m in reality the operator can overview the working area. Of course the cab can be tilted backwards to avoid an aching neck.

The Y-guying system always is connected to the boom; small hydraulic cylinders would move it into the working position.

Two massive hydraulic cylinders can adjust the lattice boom. With this additional jib the crane would be best fitted for a windmill application. And you can also show the crane with booth hook blocks; be it the 320 t main hook block or a similar one you might have in your collection at home.

The main boom head on the T3 version is also connected by the small screws and nuts as well as the sheaves for the guying system. And by the way, all sheaves are single ones and easily rotatable.

Three different hook blocks are provided together with the model; in reality these would be responsible for a load of either 320, 112 or 16 metric tons. The last one is a single line hook. Depending on the boom system you need to choose the hook. For this heavy-duty application with T3 boom the 11-sheave main hook has to be used.

For the T7-version with or without lattice jib I use the 3-sheave hook for loads up to 112 metric tons. All hook blocks come equipped with easily rotating sheaves; and the hook itself is also rotatebale.

These accurate details continue also onto the crane carrier. Engine exhaust, air filter and access ladders are copied very well. Even a small toolbox attached to one outrigger exists beside of the standard lightings, mirrors wipers and even a license tag!

On the superstructure you can see the handrails, stairs and access walkways. The engine exhaust is also inserted in its special position. A small space between the handrails provides space for the Y-guying system.

For the first time NZG uses here also pistons looking as in reality; the screw thread is positioned within the outrigger and cannot be seen from outside – which looks great. The outrigger pads then I fix with small bolts on each outrigger. Together with the crane mats this is a really fantastic detail on this giant.

While traveling the outriggers rest in a special space in-between the carrier. And on all tires you can find authentic rims and also the tire manufacturer ”Michelin” is integrated into the tires.
