How to build a brick tower crane

Step-by-step instructions

  1. 1 The strong cross base

    The brick tower crane after step 1 of 7, the strong cross base: new pieces outlined, earlier ones faded

    Lay the green plate down and add blue bricks. Put long legs out in four directions and gray ballast blocks in the corners so it can't tip!

    Find: 8 blue 2×4 bricks, 4 light gray 2×2 bricks, 2 yellow 2×4 bricks, 2 white 1×4 bricks, 1 green 2×8 brick, 1 green 4×8 plate

    Did you know? Real tower cranes stand on a concrete foundation that can weigh more than 100 tonnes.

  2. 2 The tall striped mast

    The brick tower crane after step 2 of 7, the tall striped mast: new pieces outlined, earlier ones faded

    Stack ten little square bricks right in the middle, red then white. Your mast grows taller than your hand!

    Find: 5 red 2×2 bricks, 5 white 2×2 bricks

    Did you know? Tower crane masts are built from steel sections, and the crane can lift new sections to make itself taller.

  3. 3 The long red jib

    The brick tower crane after step 3 of 7, the long red jib: new pieces outlined, earlier ones faded

    Lay gray and white long bricks across the mast top. Then cover them with red bricks so no gaps line up. The long arm points forward!

    Find: 4 red 2×4 bricks, 2 light gray 2×8 bricks, 1 red 2×8 brick, 1 white 2×6 brick, 1 white 2×4 brick, 1 red 2×2 brick

    Did you know? The long arm is called the jib, and the short arm behind it is the counter-jib.

  4. 4 Counterweight and cab

    The brick tower crane after step 4 of 7, counterweight and cab: new pieces outlined, earlier ones faded

    Hang four gray bricks under the short arm. That's the heavy counterweight! Then tuck the yellow cab with its clear window under the front.

    Find: 4 light gray 2×4 bricks, 1 yellow 2×2 brick, 1 clear 1×2 brick, 1 yellow 1×2 brick

    Did you know? Counterweights are big concrete blocks that balance the load so the crane doesn't tip forward.

  5. 5 The pointy peak

    The brick tower crane after step 5 of 7, the pointy peak: new pieces outlined, earlier ones faded

    Stack three yellow squares on the jib above the mast. Lay two long white bricks across the top, then add the red warning light!

    Find: 3 yellow 2×2 bricks, 2 white 1×8 bricks, 1 red 1×2 brick

    Did you know? Cranes have red lights on top so airplanes and helicopters can see them at night.

  6. 6 Stepped tie bars

    The brick tower crane after step 6 of 7, stepped tie bars: new pieces outlined, earlier ones faded

    Build little staircases of thin bricks from the white top down to each arm. Every step hides under the one above!

    Find: 4 blue 1×4 bricks, 4 dark blue 1×4 bricks, 4 red 1×4 bricks

    Did you know? Tie bars pull up on the jib like strings, so a long arm can be held up without bending.

  7. 7 Trolley, hook and load

    The brick tower crane after step 7 of 7, trolley, hook and load: new pieces outlined, earlier ones faded

    Snap the black trolley under the middle of the jib. Hang a thin black-and-white rope, then the yellow hook and the tan crate swinging high in the air!

    Find: 2 tan 2×4 bricks, 2 black 1×2 bricks, 2 white 1×2 bricks, 1 black 2×2 brick, 1 yellow 2×2 brick

    Did you know? The trolley rolls along the jib on wheels, moving the hook closer to or farther from the mast.
