The LEGO model of the bucket wheel excavator

The bucket-wheel excavator is one of eight machines or landmarks recreated in LEGO in the pages of Guinness World Records 2019.

Now it's your chance to win this kit, the Largest commercially available LEGO® Technic set with 3,929 pieces.

Developed in the early 20th century, the earliest bucket-wheel excavators were inspired by water dredgers.

Despite their size, the basic principle of these machines is very simple: as the wheel at the front of the excavator rotates, the buckets turn and scoop, then drop the earth on to the conveyor belt at the top of the machine which carry it away.

The machines are capable of moving 240,000 cubic metres (218,880 tonnes) of soil per day.

Modern bucket-wheel excavators perform this task on a mammoth scale, crushing roads they travel on. The biggest of these machines is called the Bagger 293, built in 1995 by TAKRAF.

It holds the Guinness World Records titles for both the Heaviest land vehicle and the Largest mobile industrial machine. Part of a family of five other ‘sibling’ vehicles of around the same size, it weighs 14,200 tonnes (31.3 million lb) and it requires five people to operate it.
