What can I build with it?Description
A roller for the building site
Road rollers are among the vehicles children love to watch on real construction sites, since they roll so slowly and weightily over fresh surfacing. This set reproduces a machine with one large drum that flattens the ground. At 208 pieces the model is compact, yet there is a good deal of engineering in it. The drum is the eye-catcher, while the cab and the details around it make the vehicle convincing and invite play on a living-room-carpet building site of your own. Thanks to the modest piece count the build fits comfortably into one afternoon.
Warning-sign yellow
Yellow dominates, supported by black, dark bluish grey and light bluish grey. That is the classic colour world of construction machinery and fits neatly with the other sets in the building-site range. With 82 different element types in just 208 pieces the mix is versatile, so you get many unusual shapes that rarely appear in simple sets. That makes the roller interesting for tinkerers who hunt for parts for their own vehicles. Grey elements add to that, as they turn up as metal, stone or machinery in many models.
Two figures on the job
The two minifigures represent the site crew and turn the vehicle into a small scene. One can drive the machine while the other directs traffic or checks the ground. Play is clearly the priority here, even though the model also looks good on a shelf. After more than ten years, used copies are often still in good shape because the bricks are tough, although stickers sometimes suffer. It pays to look closely at the seller's photos before you buy.
Ideas for the parts
The parts list on this page gives every element with quantity and colour, helpful when checking a second-hand set. With “What can I build?” you can see which models come out of the roller's bricks and the rest of your collection. Yellow and grey elements suit diggers, cranes and lorries, and they are ideal for your own construction vehicles. With a little imagination even the drum alone can become a barrel, a wheel or a roller in other builds.
