1:50th Scale Liebherr R944C Tunnelling Excavator Presented here is the 1:50th scale Liebherr R944C tracked tunnelling excavator from NZG. The R944C tunnelling excavator is the largest in the range from Liebherr, weighing in at 43.5 tons with a powerful 6-cylinder D936L diesel engine generating 258hp. It was introduced in 2007 at the Bauma trade fair and ever since I saw this strange and unusual machine, I have hoped that a model would be produced. NZG have done an amazing job in capturing the functionality and ruggedness of the machine with a host of details and features which stand out. The level of realism on this model appears to be higher than usual with some very intricate touches. Take the rear counterweight for instance, the lights are set back with tiny photo-etched protective plates covering them and even the silver bolt heads have been replicated. The tracked undercarriage consists of individual metal track pads with dual grouser ridges and bolt fixing details cast into the surface of each pad. The track frames are tensioned allowing the track to remain tight but they can still be rotated and silver finished access steps are present on both sides
The model is supplied with two different work tools. The standard ripper bucket has an interesting design with shallow sides and three large teeth which have been captured very well. The second attachment is a milling cutter which has very realistic looking cutters mounted to the rotating spindle. Flexible piping has been added which push fits into the hole on the underside of the arm. The open ROPS cab has been cast with intricate front debris protection with integrated roof lights and grab handles. The safety aspects of the machine have been replicated with clear windows on the side and rear of the cab to simulate the lexan screens fitted to the full sized machine. The floor panel has a textured surface with the operator's console featuring a seat with integrated arm rests and joystick controls have all been replicated. Additional touches on the model include rear view mirrors along with a mirror on the rear couterweight to help the driver see behind the machine. The body castings have crisp cooling grill detailing with accurately scaled safety rails and grab handles whilst the body panels have door handle detailing which has been highlighted with paint to increase the level of realism
