The Liebherr LTM 1110-5.1 Mobile Crane was first announced at the Bauma Exhibition in 2019.

It has a maximum capacity of 110 tonnes. 


The model comes in a Liebherr branded box sleeve which encloses expanded polystyrene trays.

The review model had no defects or missing parts.

There is an instruction sheet for the model which is pictorial, and it has a list of parts. The only thing it misses is a reeving diagrams for the large hook, although this straightforward.  Various mirrors and a screen have to be fitted.


The carrier chassis models the structure, and the drive transmission is modelled in plastic.  The wheels are different on the driven and non-driven axles, and the tyres have a good tread pattern with 'Michelin' in the sidewalls. 

The carrier cab has beacon lights and very good detailing, and there is an attachment point for the hook block during transport.  Various mirrors are plastic and would have looked better in black rather than grey, and with silvered surfaces.

Behind the cab the exhaust has a mesh enclosure, and there is a holder for the single line hook although it can only store it upside down.  The deck has various ladders and other parts detailed.  A high point of the carrier is the detailing including many small graphics and replica rubber skirts above the wheels.

At the rear there is a very good tool box with replica timbers stored inside.

The outriggers are single stage at the front and two stage at the rear, with the inner stage of the rear outriggers being tough plastic with an excellent colour match.   There are graphics with individual post numbers. The outrigger pistons are smooth when extended, and the pads are plastic.

The crane cab has a windscreen wiper and signal lights, and the grab rails are metal.  Inside, the detail is good with a large control console and joysticks visible.  Behind the cab the steps and walkway have a textured surface in metal with the top handrail modelled in plastic.

The counterweight is accurately modelled in separate parts.  One section has the Liebherr name embossed and there are chevron graphics and useable lifting eyes.

The large main boom ram has a plastic jacket and it has a very close colour match to the metal parts.  The boom has detail on the lowest boom section including a plastic cable drum.  Each telescopic section has graphics applied and there are metal sheaves in the boom head.

The fly jib is a very nice metal lattice casting with a plastic solid section which has an excellent colour match. All sheaves are metal.

The main hook block has three sheaves and a single line hook is also included.  A Liebherr flag is provided as a load although it does not hang so well off the main block.


The front and rear axle pairs are linked.  All axles steer with a very good range of movement and different steering modes can be replicated. 

The crane deck has multiple ladders which can be rotated and lowered to provide access to the deck.

The handrail on the crane body can be folded for transport or raised when in service.

The outriggers have extending beams and pistons that screw down without any visible screw threads.  Plastic pads clip on securely.  The outrigger pistons have enough movement to pose the crane wheels-free.

The crane cab tilts and can hold any pose.  It has an extending walkway platform.

The boom is raised using the large ram which has a locking mechanism.  The collar rotates and is used to clamp and unclamp the piston.  It works well when fully tightened. 

The telescopic sections extend smoothly and lock into place at approximately 50%, 90% and 100%. 

The winch drum is turned by finger on the drum, and the brake is by means of friction rather than a positive lock.

The fly jib can be installed at half or full length.  It also has a ratchet for setting offset angles of 20 or 40.


t is a strong model which is both heavy and robust.  Plastic is used appropriately.

The paintwork is very good as are the many graphics.


It is a reasonable price for a five axle crane.


This is an excellent model of the LTM 1110-5.1.  It is very functional and it is pleasing to see the high level of detail achieved by the addition of small graphics.  It would also look great in company colours.


The model became available in April 2021.
