LEGO Technic Dump Truck 42147 – 2in1 Construction Vehicle for Kids 7+

Two-in-one construction fun

Meet LEGO Technic Dump Truck 42147, a 2in1 toy that combines a steerable dump truck with a rebuilt excavator. With 177 pieces, this set invites kids ages 7+ into the world of engineering through hands-on building and role-play on their own pretend site.

What you build and how it moves

The Dump Truck can be steered, letting kids imagine navigating a busy construction zone. When ready, lift the tipper to dump a load, then transform the model into a powerful digger for a fresh round of play. This dual-build approach adds variety without needing a new set.

• 2 building challenges in 1: Dump Truck and Excavator
• Steered vehicle with a tipping function to drop loads
• Transform the model into an excavator for added play options

Realistic LEGO Technic experience

LEGO Technic builds bring authentic movement and mechanisms. In this set, the excavator arm can be raised or lowered, introducing kids to simple engineering ideas while keeping play accessible and fun.

• Realistic movement and mechanisms across both builds
• Excavator arm offers range of motion for engaging role-play
