The Liebherr 1050-3.1 is a 50 tonne capacity three axle crane with a maximum lifting height of 54m.

The model is in the colours of the US crane hire company Digging and Rigging.   Although their website does not list a LTM 1050, it does list the 3-axle LTM 1055.


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.

There is no information on the real machine included, and no instructions for the model either. 


This is a highly detailed model and underneath it has fully replicated transmission and suspension systems, and although these are modelled in plastic, the quality is high.  The wheels are very good with a decent tread pattern on the tyres.

The details on the carrier are of a very high standard.  There is a tiny loop for hitching the hook whilst travelling, and the door steps and handles look authentic as do the door mirrors and windscreen wipers.  Underneath the cab, a ladder is hung.  Inside the cab Liebherr is printed on the seat backs and the computer console and dashboard have graphics applied.

There is some more really good modelling behind the driving cab with mesh grilles which look very authentic together with some tiny grab handles and a realistic exhaust pipe.  Nice black replica rubber skirts sit above each wheel. At the rear, there is very fine detailing of the light bar and number plate, and there is a tool box.

The outriggers are very good having pistons which are smooth with the screw mechanism being internal so they look realistic. Small plastic spreader plates are also provided and this is a worthwhile addition.

The crane body continues the high level detail with hydraulic hosing and a nicely replicated cab interior.  The cylinder jackets on the hydraulic cylinders are plastic with a very good colour match.

The counterweight has been made in pieces so can be attached just like the real crane, and one piece has the Liebherr name formed within the casting.  A single winch is provided.

Detailing on the boom includes various spooling drums and cable runs, and looks very good.  At the boom head individual metal pulleys are provided.  There are Digging and Rigging graphics on each boom section.

A metal folding fly jib completes the model, and it has well formed lattice work.  A good metal hook is supplied, as is a dummy load with the Liebherr name on it.  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.  Although the hook can be reeved onto the fly jib, a single line hook would have looked better.


Each axle steers independently with the steering movement on the centre axle less than the others.  The steering is 'notched' but some reasonable angles can be achieved, and the crane can be posed with crab steering if required. 

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 is not huge.

The operator's cab can be tilted to a good angle, and the side access platform can be extended and retracted. 

The ladder stowed underneath the carrier cab is removable but is too short to pose in use during attachment of the fly jib.

A good feature is that the four-piece counterweight can be displayed in various configurations, including on the carrier deck when the crane is in transport mode. 

Raising the four section boom is easy but the cylinder is not stiff enough to hold an extended or loaded boom up for long without it bleeding down and this is compounded by the fact that it cannot be raised to as steep an angle as the real crane.  It can be fixed at a steep angle using a supplied pin in the main lift cylinder jacket.

A key is provided to operate the winch which on the review model had some friction so light loads could be supported.  A small opening flap is provided above the winch drum.

The fly jib can be attached although there are no pulleys at the end of the lattice section so the swing away section needs to be used.  It can be stripped down to form the very short assembly jib which is an option on the real crane.  However it was very difficult to detach the short jib on the review model.


The model is high quality with intricate detailing and where plastic is used it is used appropriately and without spoiling the look. 

The paintwork and graphics are excellent.


The model is good value.


It is good to see a crane model in the colours of a US company, and the Digging and Rigging colour scheme looks great.  This model was first introduced in 2010 and still holds its own in terms of detailing.


The model was first introduced in Liebherr colours as WSI 9478 and was available from March 2010.  A number of versions in different liveries have been produced.
