the second actuator member is operably attached to the second threaded rod and the equipment support so that rotation of the second threaded rod between the second upper rotational bearing and the second lower rotational bearing with the motor causes the vertical movements of the equipment support within the second range of movement; and
the second actuator member comprises threads that are operable with corresponding threads of the second threaded rod to:
cause the vertical movements of the equipment support when the second threaded rod is rotated;
stabilize the equipment support during the vertical movements; and
maintain a vertical position of the equipment support at each height of the plurality of different equipment support heights when the second threaded rod is not rotated.
