Free Construction-grade Mobile Crane Woodworking Plan

Junior operating engineers will enjoy doing the heavy lifting with this fully operational construction toy. The hand-operated hoists raise and lower the boom and bucket, and the tower assembly pivots smoothly on a ball-bearing lazy Susan to easily pick up and place loads. The wide-track chassis features eight sets of dual wheels for sure-footed mobility. If you like this plan, check out the entire line of Construction-Grade Toys.
