Photographs and text introduce children to different types of cranes, including a mobile crane, an all-terrain crane, floating cranes, aerial cranes, and more.

This title has great visual appeal for elementary readers. Sharp, eye-catching color photos of various types of cranes in action are the stars of this book. The parts of each crane are identified on the photo with captioned arrows. The parts further defined in the text or a separate glossary box. The text uses two fonts on each two page spread: a larger font to introduce the specific crane and its use and a smaller font to explain how the crane works. Each two page spread features a large photo of the crane as well as an inset photo. A total of ten cranes are featured, among the various cranes discussed are a floating crane, a crawler crane, and a telescopic crane. The glossary defines each crane, as well as several other words associated with cranes. The text is best handled by middle readers but the photos and diagram will be enjoyed by readers of all grades. Two of the three websites are appropriate for the reading level. Zajko, Rosanne
