§4896. Controllers.

(a) Cranes not equipped with spring-return controllers or momentary contact pushbuttons shall be provided with a device which will disconnect all motors from the line on failure of line power and will not permit any motor to be restarted on line power until the controller handle is brought to the "off" position, or a reset switch or button is operated.

(b) For cranes operated from the floor, the controller or controllers, if the controller is rope or line actuated, shall automatically return to the "off" position when released by the operator.

(c) Lever-operated controllers shall be provided with a mechanical device which will hold the handle in the "off" position, requiring voluntary effort to move it from the "off" position to the "on" position.

(d) All electrically operated cranes shall have their controllers plainly marked to indicate their function and the equipment they control. As far as is practicable, the movement of each controller handle shall be in the same general direction as the resultant movement of the load.

(e) The controller operating handles shall be located within convenient reach of the operator.

(f) The controls for the bridge and trolley shall be so located that the operator can readily see the direction of travel while operating the controls.

(g) All electric cranes of similar design operating in a given plant shall be so wired that like motion of controller handles will produce like effect in similarly controlled mechanisms.

(h) Remote-operated cranes shall function so that if the control signal for any crane motion becomes ineffective, crane motion shall stop.

(i) Automatic cranes shall be so designed that all motions shall failsafe if any malfunction of controls occurs.

(j) Pendant controller controls shall return to the "off" position when released by the operator.
