The tallest tower cranes can lift things higher than a 20-storey building.

They reach hundreds of metres up into the sky. That is how workers build super-tall towers, floor by floor.

The biggest dump trucks have tyres taller than a grown-up person.

Each giant tyre can be about 4 metres tall. These huge trucks carry loads as heavy as many elephants.

Cement mixer trucks spin around to keep the wet concrete soft.

The big drum turns slowly so the concrete does not go hard. When it arrives, the wet concrete is ready to pour.

Cranes lift heavy things high up to help build tall buildings.

A long arm and a strong cable pull loads up into the air. Cranes can lift steel beams many floors high.

Bulldozers push piles of dirt with a big flat blade at the front.

The wide metal blade shoves earth out of the way. Bulldozers help make the ground flat before building starts.

Dump trucks carry heavy loads of dirt and tip them out the back.

The big box on the back tilts up high. All the dirt slides out in one big whoosh.

Excavators use a big metal arm and bucket to dig holes in the ground.

The strong arm scoops up dirt and rocks. Then it swings around and drops them in a pile or a truck.
