The Hy Hy Dolly offer an excellent, secure base for the wide range of jib arms offered at Whites: Aerocrane, Advanta-jib, Porta-jib, Straight Shooter, Tele-jib, Meerkat and CG10.  The Hy Hy Dolly can be adapted with either Euro or Mitchell mounts.  The Hy Hy Dolly is based on the Chapman Hybird and has pivoting wheels to widen the base while providing crab and two-wheeled steering.
