42121 Heavy Duty Excavator is a TECHNIC set that was released on March 1, 2021.

Background

Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels.[citation needed] All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which use winches and steel ropes to accomplish the movements.

Looking for a special gift for kids who love construction toy sets? This 2-in-1 LEGO® Technic™ Heavy-Duty Excavator (42121) toy has plenty of features for hours of creative play. Boys and girls aged 8 and up will enjoy an immersive building challenge before exploring the digger toy's realistic features.

Digging, driving, rotating; there's so much to discover in this cool kids' excavator toy. Check out the shovel that moves up and down, plus the movable arm, running belts and rotating body. There’s also a detailed cabin with a driver’s seat and control panel. The set comes with extra LEGO brick ‘stones’ to dig and 4 cones. When it’s time for a new challenge, the model rebuilds into a tracked tractor with backhoe.

Heavy Duty Excavator Reviews

“ I think this is a great set for its target market. This isn't meant to compete with the $100+ sets like the motorized 8043 or massive Bucket Wheel Excavator. This is a set kids will get and love. I particularly appreciate that the instructions start with building the arm and . More even call out to test the functionality before moving on to bag 2. That's a great user experience right there.”

“ It's a realistic and compact model that packs a good amount of functionality into its demure size. It works well and is likely to be fun to play with if you're the right age to do so. The arm looks a bit out of scale with the body to me, but it's not a deal-breaker. . More Unfortunately, the frosty windscreen mars what would otherwise be a pretty much perfect model.”

“ It is smaller than expected, but that can be seen as a positive. It offers similar functionality to much larger vehicles of this type, but doesn't take up masses of space on the shelf. The finished model looks excellent, the digging feature is fun to use (once mastered) and . More it retails for a very respectable price. Overall, 42121 Heavy-Duty Excavator is a set we really… dig.”

Theme Analysis

About Technic

TECHNIC is one of The LEGO Company's main lines based on creating detailed model machines and mechanical toys with specialized beams, axles, gears and connectors and primarily designed for older children and adults. The theme was first introduced as the Expert Builder series in 1977, but was officially renamed as TECHNIC in 1984. TECHNIC is still an active theme, and is one of the longest running themes in LEGO history. While most TECHNIC sets are vehicles that use pieces to mimic real vehicles, such as engine pieces, suspension, pneumatic, and transmission pieces, the TECHNIC parts have been used by various other System themes as well as LEGO Mindstorms.

Packed with realistic features, this digger toy set lets kids see how construction vehicles really work. Check out the moving shovel and arm, plus running belts, just like on a real excavator.
