Children have a huge fascination for excavation pits. Earth, gravel, sand, and mud, large machines and loads. With the new SIKUWORLD set, the playroom becomes a major construction site. The set consists of four new ground panels, whose colour theme and form create an excavation pit, but are also compatible with the other panels in the SIKUWORLD. The site hut has been erected, the barriers set up, and the large construction site crane is in place. The construction work can start: The boom pivots, and the mobile trolley can be used to pick up the construction materials on the hook, and to set them down on the conveyor belt and sorting unit. The conveyor belt can be moved using a rotating knob. This conveys the waste material to the sorting unit. This sorts the materials for removal for re-use onsite. The versatile tractor included in the set has a trailer coupling for manoeuvring the machines on the construction site. Product dimensions w x d x h (mm)540x540x235.
