LEGO MINDSTORMS Robot Inventor
This crane model requires some string, which is not included in your kit, but most types of string should work including fishing line. Two motors are used to power winches that pull two string lines to operate the boom (arm) angle and the hoist (hook height), and a third motor rotates the entire crane around in a circle on its base.
Using the remote control program, you can reach loads close to or far from the crane, lift them, pivot the crane around, and place the load somewhere else. Normally construction cranes have another person on the ground to help hook and unhook the load, and you can do this manually if you want, but with some practice you can also do it entirely with the crane controls.
