Mini Crane
9391-1 Technic 2012 218 parts 0% repair risk Easy
The LEGO Technic 9391-1 Mini Crane from 2012, a 218-piece set, is engineered for construction tasks. Its tracks allow site traversal. The superstructure rotates, and the boom raises with an arm that extends to lower the hook. This model demonstrates Technic functionality, mimicking crane operations. It rebuilds into a bulldozer featuring a blade that lowers and a ripper. The crane stands over 30 cm high and 27 cm long, a notable replica for display.
