Section - 46 - Cranes and Other Lifting Machines

    (1) All parts and working gear whether fixed or movable, including and anchoring and fixing appliances, of every lifting machine shall be of good construction, sound material, adequate strength and free from patent defect, and shall be properly maintained.

    (2) All rails on which a travelling crane moves and every track on which the carriage of a transporter or runway moves shall be of proper size and adequate strength, and have an even running surface, and any such rails or track shall be properly laid, adequately supported or suspended, and properly maintained.

    (3) There shall be plainly marked on every lifting machine the safe working load or loads thereof, except that in the case of a jib crane so constructed that the safe working load may be varied by the raising or lowering of the jib, there shall be attached thereto either an automatic indicator of safe working loads or a table indicating the safe working loads at corresponding inclinations of the jib or corresponding radii of the load.

    (4) No lifting machine shall, except for the purpose of a test, be loaded beyond the safe working load as marked or indicated under subsection (3).

    (5) If any person is employed or working on or near the wheel track of an overhead travelling crane in any place where he would be liable to be struck by the crane, effective measures shall be taken to ensure that the crane does not approach within twenty feet of that place.

    (6) If any person is employed or working otherwise than as mentioned in subsection (5) but in a place above floor level where he would be liable to be struck by an overhead travelling crane, or by any load carried by such a crane, effective measures shall be taken to warn him of the approach of the crane, unless his work is so connected with or dependent on the movements of the crane as to make a warning unnecessary.

    (7) A lifting machine shall not be operated except by a person trained and competent to operate that machine, except that it shall be permissible for such machine to be operated by a person who is under the direct supervision of a qualified person for the purpose of training; and no person under the age of eighteen shall be employed to operate any lifting machine driven by mechanical power or to give signals to its operator.
