I realize that we read a collection that included this book many years ago. This collection has dump trucks and other giant construction equipment. It is the standard style that includes lots of very sharp pictures with a primary descriptive text and additional details and sub-pictures. It is fun for kids.
The Great Big Book of Mighty Machines by Ian Graham and Jean Coppendale
This book collects a half-dozen "vehicle" books under one cover. Each section groups together a set of vehicles (like cars), and provides a big picture and description of it on a page. The vehicles range from BMX bikes to mining dump trucks and all sorts of things in between. It is actually fairly readable, with a bit of progression through each section. However, it never tries to tell a narrative. The real purpose is pictures of all sorts of big machines. There are obvious "detail" sections for each vehicle that can double the length of the book - though it can easily be read without them.
Five year old boys love it.
