Istruzioni per l'uso
The LEGO Technic Mobile Crane 42108 is designed with several functional features that mimic a real mobile crane. Familiarize yourself with these operations for optimal interaction.
1. Steering the Vehicle
The mobile crane features an advanced 8-wheel steering system, allowing for precise maneuverability. Use the designated controls to steer the vehicle to its desired location.

2. Deploying Outriggers
For stability during lifting operations, the crane is equipped with four individually controlled outriggers. These must be extended and lowered to secure the crane in place before raising the boom or lifting loads.
- Locate the controls for the outriggers on the crane chassis.
- Extend each outrigger outwards from the vehicle body.
- Lower the outrigger feet until they firmly contact the ground, providing a stable base.

3. Operating the Boom and Hoist
The crane's primary function involves raising and extending its telescopic arm and operating the hoist to lift and move objects.
- Raise the Boom: Use the control mechanism to elevate the main boom to the desired angle.
- Extend the Telescopic Arm: Once the boom is raised, extend the telescopic sections to reach greater heights.
- Operate the Hoist: Use the winch control to lower the hook, attach the load (e.g., the concrete pillar accessory), and then raise or lower it as needed.
