ABSTRACT:
A toy crane attachment for use with a child's tricycle. The crane includes a main mounting frame which can be easily attached to or removed from the tricycle. The main frame pivotally supports a swivelable frame and boom, with the boom thereby being movable not only horizontally relative to the tricycle, but through all of a crane's vertical motions. The child will operate the crane by turning around and facing the rear of the tricycle with crane operation thereafter simulating actual crane operation.
