DIY STEM simple crane model creative kids toys for play school

Description

DIY STEM simple cranes are cyclic and intermittent machines that move in cycles. A working system includes the following steps: the retrieval device lifts the item, then moves horizontally to a designated place to drop the item, and then performs a reverse movement to return the retrieval device to its original position for the next cycle.

The DIY crane model is driven by a worm and gear and a wire control box is used to control the forward and reverse rotation of the motor to drive the rope and hook the item to move up and down direction. The assembly is simple, vivid, and visually appealing. This kid's toy can be washed with water when it is dirty. And come with a sturdy storage box for easy clean-up and organizing of the parts.
