LEGO Technic Material Handler Crane 42144 — 835-Piece Construction Toy for Ages 10+

Overview

Meet the LEGO Technic Material Handler Crane (42144), a build that blends engineering realism with imaginative play. This 835-piece set is designed for kids ages 10 and up who love mechanical models and construction-site storytelling. The finished toy offers a sturdy, impressive presence, standing about 12.5 inches tall (33 cm), 15.5 inches long (40 cm), and 6.5 inches wide (17 cm).

Realistic mechanisms you can explore

The model combines pneumatic and manual functions to mimic how a real material handler operates. A movable pneumatic arm reaches out to about 13 inches (35 cm), and the classic orange peel-style grapple opens and closes to grab and lift materials. In addition, a 360-degree rotating upper arm, an elevating operating cab, and a mobile undercarriage with steering along with four outriggers give the build a lifelike range of movement.
