Doc's Exacto-Built Meccano Tower Crane

Hi folks, Doc here. Here's my fourth model built with the Exacto Crane and Helicopter Set: the Tower Crane. It's one of eight different crane designs included in the detailed instruction manual. The model shown here features a cab/boom/motor assembly that swivels atop a tower made from truss and angle girders. The long thin boom can be raised and lowered manually by means of a crank on the side of the cab, while the hook is raised and lowered using the geared down motor mounted above the counterweight at the rear of the boom/cab assembly. The finished model measures 20" tall by 27" long.
