The Liebherr LTM 1055-3.3 Mobile Crane has a maximum capacity of 55 tonnes. 

Packaging

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

The review model had no missing parts.  One part. A19, was incorrectly made as well as a broken deck ladder.

There is an instruction sheet for the model which is pictorial, and it has a list of parts. It describes most but not all features.  Various mirrors have to be fitted.

Detail

The carrier chassis models the structure well, and the drive transmission and suspension 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 but they do not have silvered surfaces.

Behind the cab the the engine area has various textured surfaces .  The deck has plastic ladders.  A high point is the detailing including many small graphics and skirts above the wheels.

At the rear there is a plastic tool box with replica timbers stored inside.  Lights are painted.

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.   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 there are beacon lights at the back.

The counterweight is 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 colour applied but it is not a good match for the Liebherr yellow elsewhere.  There are metal sheaves in the boom head.

The fly jib is a very nice metal lattice casting with a plastic section which has a hollow underside so does not look so good. All sheaves are metal.

The main hook block has three sheaves and a single line hook is also included. 

Features

The front axle pairs are linked.  All axles steer with a 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 outriggers have extending beams and pistons that screw down without any visible screw threads.  Plastic pads clip on securely.  The outrigger pistons have just enough movement to land solidly.

The crane cab tilts and can hold any pose.  It has an extending platform underneath which was very stiff on the review model.

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 46%, 92% and 100%. 

The winch drum is turned by key, 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.  However, the plastic ratchet is clunky and does not work well with long pins used to secure the jib to the boom head.

Quality

This model is not as robust as usual for a Conrad model.  The rear axle easily detaches from its weak securing clip, and other plastic parts are not glued so drop off too easily.

The paintwork is very good with the exception of the colour on the telescopic sections.  The many tiny graphics are impressive.

Price

It is moderate value overall.

Overall

This model looks nice when posed, but some aspects of the build quality and model engineering are a little disappointing by modern standards.
