Major realism – major lifting power!
Lift nearly anything with this heavy-duty Telescopic Handler! It’s loaded with realistic functions that you build right in, including a mechanical actuator that raises and lowers the extending boom, front-end stabilizers, and working four-wheel steering. You can even add 8293 Power Functions Motor Set to motorize the telescoping boom!
Turn the knob on back to raise and lower the boom, then flip the switch the extend it!
Tilt the front forklift to pick up the cargo pallet!
Boom extends over 21" (53cm)!
Telescopic Handler measures 15" (38cm) long and 15" (38cm) high!
This was one of the first sets to use the new mechanical actuators.
