The Liebherr G-LTM 1090-4.2 is an armoured crane designed for military use.  In this configuration it has a shorter 36m boom and a 37 tonne lifting capacity.


The model comes in a Liebherr branded box with the model held within a pair of polystyrene trays. 

There were no missing parts or defects on the review model.

A card included with the model contains a QR code which links through to the WSI website where information relating to the model can be posted. 


The model is highly detailed and underneath it has fully replicated transmission and suspension systems.  There is added protection at the front of the chassis. The wheels are very good with a decent tread pattern on the tyres, and a slightly different wheel design on the non-driven axle.  The tyres also have Michelin branding in the sidewalls.

The details on the carrier are of a very high standard.  There is a loop at the front for hitching the hook whilst travelling.  The cab itself is a new casting and is fully armoured.  Among the great details are the rivet heads, and the small windows give it a tough look.

Behind the driving cab there are mesh grilles which look very authentic together with other parts.  Stiff replica rubber skirts sit above each wheel.  The carrier deck has got some very nice texturing which looks good in black, and there are fold-down ladders.  At the rear, there is what appears to be a winch.

The outriggers are very good having pistons which are smooth with the screw mechanism being internal so they look realistic. They close up fully in the transport position.  Small plastic spreader plates are also provided.

The crane body continues the high level detail with hydraulic hosing.  The cab on this model is fully armoured and looks impressive.  The cylinder jacket on the hydraulic ram is metal.

The counterweight has been made in pieces so can be attached just like the real crane, and the VarioBallast system is modelled well.  A single winch is provided.

Detailing on the boom includes a box and ladder. This version of the crane has a four section boom.  It has a realistic thin walled profile. At the boom head the main pulleys are a solid block as they are in the hook, and this is a disappointment.  The hook block is metal.

The high detail level includes a chain to replicate the hoist cut-off, and the free end of the hoist rope slides into a tie-off shackle. 


Each axle steers independently with the steering movement being moderate.  The model rolls in a straight line.  Steered, the model rolls but the tyres are easily fouled at the widest angle. 

The outriggers can be extended and lowered and feature 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 range of travel on the pistons is good and the model can just about be posed wheels-free and this affected by the extended outrigger beams not ending up in a straight profile.

The ladders stowed on the carrier deck can be rotated and folded down.

A good feature is that the four-piece counterweight can be displayed in various configurations.  It can be posed in two positions on the carrier deck for self-ballasting.  The VarioBallast system also works well with the counterweight able to be fixed in either of two different radii. 

Raising the boom is easy and it is locked in position using a grub screw in the ram jacket.  The telescopic boom sections have three locking positions.

A key is provided to operate the winch which has a nice and smooth working brake function.  However the hoist rope does not flow freely around the solid pulley blocks.


The model is high quality with high detail and minimum plastic. 

The paintwork and graphics are excellent.


The model is good value.


This is an interesting and unusual crane model and it is great that it has new castings and is not limited to just a military colour scheme.


The model was released in May 2022.
