Building Crane

7905-1 City 2006 721 parts 2.8% Intermediate

The LEGO Construction Building Crane (7905-1) recreates a large-scale construction site operation from 2006. This towering model stands 68 cm (26 inches) tall with an arm that extends equally to 68 cm (26 inches) for reaching across building zones. Its design features an extra-wide base, ensuring stability as it lifts and moves loads. Builders can operate the crane's working hook by turning a side crank, precisely lowering and raising cargo. A dedicated hook dolly slides along the arm, enabling accurate positioning of materials. The crane tower allows a minifigure to sit at the controls, directing operations, while a side ladder provides access to the top. The entire structure rotates a full 360 degrees, simulating dynamic construction movements. The set includes three minifigures, two specialized containers with lifting loops, and various barriers to delineate the work area.
