An orchestra shell tower and tower transporter system has a plurality of shell towers comprising an acoustic central panel hingedly connected along its side edges to acoustic wing panels. A generally horizontally rearwardly extending tripod-shaped open base is fixed to the lower end of the central panel and counterweights both the central panel and the wing panels. Vertically adjustable dependent legs with stage engaging members are provided on the tower. A tower transporter has a forwardly extending tripod-shaped open base supported on caster wheels and configured to be received within the base of each of the shell towers. Vertically movable lifters on the transporter base have receptors for engaging the legs of each of the tower shells in lifting relationship and actuatable motors are provided on the transporter for raising and lowering the lifters, and thereby the tower engaged by the transporter for supporting the tower in a raised position for travel.
