Pam9156, can you give a little more information about the rules that were handed out?  How heavy is the object?  Is it any particular shape?  Are there any restrictions on the materials you can use?  Where does the energy come from (can you pull a cord, turn a crank, push a lever, electric motor)?  Can you tie a cord around the object?

Come back to this question and add some detail.

Images that come to mind are

1. A tower, like a tripod, made of wood above the object with a pulley, like an elevator.

2. Similarly, a simple crane or long lever.  You could, after all, lift an object with a see-saw.

3. A ramp with a mechanism for pulsing or pulling the object up.

I'll follow-up with more ideas and some resources if you can add some detail.
