Description
The LEGO Technic Material Handler (42144) is an 835-piece mechanical crane construction toy designed for builders aged 10 and up. Originally released in August 2022, this set introduces engineering principles using a blend of manual controls and realistic air-powered pneumatic systems. [1, 2]
Mechanical Features
- Pneumatic Functions: Powered by a manual hand pump and three switches to control a multi-part movable arm with a 13-inch (35 cm) reach and an "orange peel" style grapple claw. [1, 2]
- 360-Degree Rotation: Built on a heavy turntable allowing the upper superstructure and arm assembly to spin completely around. [1, 2, 3]
- Elevating Operator Cab: Features a hand-turned gear mechanism that raises the driver's cabin up and down to grant the operator a better vantage point. [1, 2]
- Stabilizer Undercarriage: Includes front-wheel steering alongside 4 manual outriggers that extend downwards to lift the entire vehicle off the ground for stable lifting. [1, 2, 3, 4]
Core Specifications
- Piece Count: 835 pieces.
- Dimensions: Measures over 12.5 inches (33 cm) high, 15.5 inches (40 cm) long, and 6.5 inches (17 cm) wide.
- Pneumatic System: Uses the updated Pneumatic V2 system with a dark gray hand pump and three cylinders; it operates without an air tank, meaning manual continuous pumping moves the parts.
