Construction Equipment. My First Encyclopedia with Stickers

For centuries, people have tried to ease manual labor and make it more efficient. The atlas will introduce the child to the entire variety of mechanical helpers of mankind – from the ancient water-lifting wheel to the giant walking excavator... the length of one and a half football fields.
How did an ordinary shipworm inspire the invention of a machine for tunnel construction? And why has the world's largest bulldozer never worked? Answers to these and other questions will delight the curious child through familiarity with the encyclopedia. A multitude of interesting facts, stories of clever engineering solutions, colorful illustrations – all this will capture the child's attention for a long time.
Having read this encyclopedia, the child will be able to lead a mega-construction and, with the help of bright reusable stickers, assign tasks to their iron workers.
