A rack mover, attachable to a rack, includes a wheeled jack for lifting the rack off the support surface and a jack-mounting assembly. The jack-mounting assembly includes a first member to which the jack is coupled and a second member including hooked projections extending a length through respective openings in the first member. The hooked projections are configured to engage the rack. A biasing member of the jack-mounting assembly biases the second member in a first direction relative to the first member such that the hooked projections extend a first length through the respective openings. A tightening assembly of the jack-mounting assembly is engaged with the second member and configured to move the second member relative to the first member in a direction substantially opposite the first direction to reduce the length of extension of the hooked projections through the respective openings to a second length less than the first length.
