The invention provides a caster having a wheel and a wheel lock assembly that is configured to lock the wheel against rotation about a first axis. The wheel lock assembly allows the caster to move between a locked configuration, in which the wheel is engaged by a detent of the wheel lock assembly, and an unlocked configuration, in which the detent is spaced from the wheel. In certain embodiments, the caster moves between its locked and unlocked configurations in response to rotation of a rotatable cam. Other embodiments provide a wheel lock assembly including a rotatable track wall, which comprises a generally cylindrical wall configured to rotate about a second axis. In such embodiments, the caster is configured such that the rotatable track wall rotates about the second axis when the caster moves between locked and unlocked configurations.
