Batteries Required: 2 X AA (not included)
1. 1 x Base
2. 1 x Switch
3. 1 x Motor
4. 1 x Connecting Panel
5. 3 x Medium Pulley Wheel
6. 3 x Pulley Pin
7. 1 x Small Pulley Wheel
• Unwind the string from the gearbox for a length of about 35cm and tie a knot around the pole of the
Shaft (10) as shown in Fig. 5.
• Install the four spring connectors (12) on the base (1) narrow end down, push the spring as far as it will
go. Connect the red and black battery wires to the ones at position 1 and 4 respectively, as shown
(Fig. 2). Bend the spring over to create a gap into which the metal wire is inserted.
• As shown in figure 7, (a) run the string around the Small pulley wheel, (b) insert the Small pulley wheel
(7) to the axis of the Hook (8) and (c) cover the hook with the Hook cover (9).
• As shown in figure 9, install the other two pulley wheels at position B and C. Then, put the string over
the pulley wheels.
• Install the gearbox onto the Shaft (10) until it is locked in position. (Fig. 6)
• As shown in Figure 3, connect the four wires of the switch (2) to the spring connectors as follows:
• Red wire (long) – 1 • Black wire (long) – 4 • Red wire (short) – 2 •Black wire (short) – 3
Insert the switch to the base afterwards.
8. 1 x Hook
9. 1 x Hook cover
10. 1 x Shaft
• Now the hook should be able to slide smoothly on the string. Install a Medium pulley wheel (5) on the
pole (A) of the shaft and secure it with the Pulley pin (6). (Fig. 8)
11. 1 x Gearbox
12. 4 x Spring Connector
13. 1 x Weight
We use electricity in our everyday life. In this kit, we will build a crane that demonstrates how electricity is
converted into mechanical motion. This crane uses pulleys to make it easier to move a load.
• Insert the Motor (3) into the Gearbox (11) as shown in Fig. 4.

• Place the Connecting Panel on the base as shown. (Fig. 10)
• Make sure the switch is set at the middle position, insert two AA batteries into the battery compartment
according to the polarity marks shown in Fig. 11
