With this Eitech Tech-construction kit, you can choose and construct between at least three different models. Whether caterpillars - or construction crane - fun tinkering is guaranteed. The crawler crane can be pushed and rotated manually so that the driving experience is not neglected. In addition, the main model has two cable winches with which the load hook and the crane arm can be moved. This metal construction kit contains a total of over 520 parts, most of which are made of galvanized steel strip. The right assembly tool and detailed, illustrated assembly instructions are included with the item.
