42128-1 Technic 2021 2017 parts 5.2% catalog rarity Advanced
The LEGO Technic Heavy Duty Tow Truck (42128-1) offers a detailed exploration of complex engineering. This 2017-piece model, released in 2021, recreates a classic tow truck with an authentic grille, air filters, lights, and exhaust pipe. Builders operate its intricate pneumatic and mechanical functions, including an accessible 6-cylinder inline engine with moving pistons under the bonnet. Steering is managed by a rotating pin on the roof. The set features a fully operational crane, allowing users to pump up the boom, extend the outriggers, and pull out the winch. A unique lifting axle mechanism also deploys extra wheels to distribute heavy loads, a pioneering feature for LEGO Technic.
