The accessory set consists of a large portal crane and a container boat with a container. The length is precisely matched to the width of a canal straight or a canal curve. In the game, children aged three and up learn to operate a crane arm and how to move containers using a rotating wheel. When the crane house is pushed, the container moves for unloading across the entire length of the crane from one side to the other. The AquaPlay ContainerCraneSet is made in Germany from high-quality UV-resistant plastic. Each package includes an easy-to-understand assembly instruction.
