Tower Crane

This toy Tower Crane is designed for 6mm thick plywood (or potentially other material), to be lasercut from 2 sheets of 600x300cm. The drawings account for 0.1mm cut width.

When assembled, the crane stands ~840mm tall (This is excluding the solid wood base). The horizontal arm ('Jib') extends ~540mm from the tower.

The hoist block can be fitted with hook or magnet.
It has 3 degrees of movement:
- up/down (~600mm),
- radial (trolley can slide ~380mm along the jib)
- axial (the top part can rotate 360 degrees)

The top connects to the tower via a 25mm diameter aluminum tube, which acts as rotation axel. Metal shafts or threaded rods (4 and 6 mm) and (plastic) gears are required for actual hoisting action.
