Abstract
A patient transport apparatus comprises a support structure comprising base, a frame, and a patient support surface to support a patient. The apparatus also includes at least one caster assembly coupled to the support structure, with each one of the caster assemblies comprising a wheel, a wheel support coupled to the wheel, and a steer lock assembly movable relative to the wheel support. An actuator is operatively coupled to the steer lock assembly to move the steer lock assembly between a non-steer locked and steer locked state to permit or prevent the wheel support and coupled wheel from swiveling about a swivel axis. The caster assemblies can also include a brake assembly coupled to the wheel, with the actuator operatively coupled to the brake assembly to move the brake assembly between a braked and unbraked state.
