Packaging

There is no information about the model and no assembly is required.
Detail
The wheels have good quality tyres mounted on detailed hubs which are different on the front and rear axles. Four stabilisers are simple screw threads with plastic pads.
At the rear the engine area is modelled well with various elements detailed in metal and there are a couple of plastic spooling reels and an access ladder.
The operator’s cab is large and is well detailed inside with two seating positions each complete with controls. Window wipers are applied graphics and there are plastic grab rails on the outside of the cab.
At the front there are three drilling booms which are have parts fixed together with small brass rivets which are not too obtrusive. At the boom head the directional motors are modelled well but without any hydraulic lines. The drill rail is metal with a plastic drill and the drill string and drill head are really good.
The access boom has a cage which is entirely metal.
Features
The rear axle has a good range of steering movement. There are four working stabiliser pads which can be lowered, with the front pair also able to be pulled out laterally on short beams.
Two spooling reels within the body can be rotated and the access ladder at the rear folds down.
The entire cab can be raised up on a telescopic mechanism for better visibility.
The range of movement of the drills is excellent as they are mounted on adjustable three stage telescopic booms with full four-way movement at the end. The drill string guide rails can slide and the drills can also be moved along the drill string guides.
The access platform has a full range of movement including rotation and can be set to any angle and height within reach.
Quality
This is a typically robust Conrad model which is heavy as it is mostly metal. The paintwork and graphics are very good.
Price
It is not a cheap model and the price reflects the high metal content and its unusual nature.
Overall
This is a surprisingly big and heavy model which is made to Conrad’s usual high standard. The functionality is excellent and It is highly recommended.
Footnotes
The model first appeared at the Nuremberg Toy Fair in 2009.
