You could build a crane that could raise small loads.
The BRIDGE BEAMS are lengths of alder (3/4" thick and 1 1/2" wide) with holes drilled every
You can stack and arrange them however you like, and use 3/8" dowels to connect
Once you add lengths of string, a lazy susan, pulleys, wheels and a windlass, the sky's the limit.
The crane is loading #3 beams onto the bed of the truck.

Here's a 2 level house. This view of the back side shows the
