Publisher's Synopsis
Giant color spreads show mammoth tower cranes, twice the height of the Statue of Liberty build skyscrapers and bridges, huge paving machines and bulldozers lay thousands of miles of road and giant dump trucks that consume five gallons of gas per mile whose tires each are as heavy as four stationwagons hauling tons of dirt. Here is the real world behind one of kids' favorite toys, the Tonka truck.
Short sections describe each machine. Accounts of famous inventors and explanations of rudimentary mechanics will educate and enthrall kids of all ages. Engaging and fun facts put the massive power and utility of the machines in perspective for the young audience.
Giant Machines covers equipment used in six industries: mining, highway construction, tunnels/drilling, farming, forestry and recycling.
