Knex Tower Crane
Intro: Knex Tower Crane
My first large-scale knex project! This is a great Knex Tower Crane that is 6.2 feet tall and has a boom 4.11 feet long. Very durable, it has stood for two months in my room under all kinds of tests. (There is a limit to it's ability, though.) I hope you like it, the crane rotates and has a working hook. You can make your own hooks for various tasks.
STEP 1: Piece Count
With this large a project, piece counts are necessary!

STEP 2: Base and Tower
Not hard, just follow the pics!
STEP 3: The Gearbox
This little rig makes the entire boom rotate with the turn of a crank!
I assume that it could be fitted with a motor if desired. I simply don't have one.

STEP 4: Boom Base and Winch
This connects the boom to the tower. Follow the pictures or the model won't work.
STEP 5: Winch Casing
This is for strength, but it also makes it realistic.
STEP 6: Counterweight Bin and Connecting Beam
This handy device will hold the counterweights to balance a load!
STEP 7: The Hook
This is my model for a hook, anything will work.
STEP 8: The Boom
This is what makes a tower crane a tower crane!
STEP 9: Final Assembly, Part 1
Connect it all, and have fun with your new awesome model!
STEP 10: Final Assembly, Part 2
Ok, now you're done!

Either you're taller than you think, or (more likely) my measurement was wrong. Sorry for any inconvenience.
