Lifting 37 - Elenco Electronics SC3DMEG Instruction Manual

Project 45
Assembly (adult supervision recommended):
1. Place base grid supports on base grid A.
2. Tie one end of a piece of string to the hole
in the gear insert, and place the gear insert
on the orange motor (M9). Insert the screw
into the orange motor shaft but do not
screw it in very far.
3. Place parts on base grid B and install into
base grid supports on grid A. Grid B
should be the two-sided grid.
4. Place the remaining parts on grid A and
connect the red and black jumper wires.
Tie a light object (such as an extra base grid support) to the other end of the string. Turn on
the slide switch (S1). The orange motor spins; pull the string away from the gear insert a
little so that the string winds around the screw, slowly raising your object. You can place the
circuit near the edge of a table to lift the object farther. Turn off the slide switch before the
lifted object reaches the slow motor and interferes with it.
Swap the connections of one end of the red and black jumper wires to make the orange
motor turn in the opposite direction and lower the object.
Don't lift a heavy object or the orange motor may fall off the base grid.
