Excavators

The word excavate means to dig, and that's just what an excavator does. Excavators are fun to watch. The giant arm bends down and the bucket scoops up a big load of dirt then swings around and drops its load. Excavators are used for many jobs including digging a foundation hole for a new house, building a road, or digging a trench for sewer pipes and utility lines

Giant Off-Road Dump Trucks

This off-road dump truck is built to move heavy loads from one place to another on construction sites or in mining operations. These off-road trucks can be as big as a house, and are much too big to drive on the same roads that cars do. The biggest truck is over 24 feet high, 27 feet wide, 50 feet long, and weighs 410,000 pounds. It can haul a 620,000 pound load. WOW!

Bulldozers

Bulldozers are used to push heavy loads for many jobs including road building, site clearing, and landfill operations. They move on steel tracks that grip the ground and give them more pushing power than rubber tires. The tracks also spread the weight of the machine over a larger area than tires would to help keep it from getting stuck in wet places.

Front-end Loaders

Front-end loaders are used to dig, lift and move heavy loads from one place to another. The loader can lift its bucket high into the air to dump loads onto stockpiles or waiting trucks. A loader on rubber tires can move loads quickly around the construction site. A busy loader operator can go backwards and forwards changing direction over 400 times in just one hour.
