A toy for building dams and like purposes is inexpensively provided which includes two spaced standards, a fixed carrier supporting line that extends between the tops of the standards, a bucket carrier operable along the carrier line, and means operable from a fixed remote control station for selectively driving the carrier back and forth along the carrier line or raising and lowering the bucket relative to the carrier while the carrier, itself, remains stationary. The raising and lowering mechanism desirably comprises a windlass which winds in and pays out a raising and lowering cable so long as the carrier remains idle. A carrier drive pulley, coaxial with the drum, may be clutched to the windlass drum for rotation in unison with the drum. When this is done the bucket is moved horizontally by and with the carrier.
