§4991. Travel.


(a) The travel of boom-type equipment and cranes shall be controlled so as to avoid collision with persons, material, and equipment. The cabs of units (of the revolving type) traveling under their own power shall be turned so as to provide the least obstruction to the operator's vision in the direction of travel, unless receiving signals from someone with an unobstructed view.
(b) In transit, the following additional precautions for mobile cranes shall be exercised:
(1) The boom shall be carried in line with the direction of motion and the superstructure shall be secured against rotation, except when negotiating turns when there is an operator in the cab, or when the boom is supported on a dolly.
(2) The empty hook, headache ball, or block shall be lashed or otherwise restrained so that it cannot swing freely.
(c) Traveling with a load is prohibited if the practice is prohibited by the equipment manufacturer.
(d) Where traveling with a load, the employer shall ensure that:
(1) A competent person supervises the operation, determines if it is necessary to reduce rated capacity, and makes determinations regarding load position, boom location, ground support, travel route, overhead obstructions, and speed of movement necessary to ensure safety.
Exception to subsection (d)(1): Marine terminal operations regulated by Article 14 of these Orders.
(2) For equipment with tires, tire pressure specified by the equipment manufacturer for traveling with a load shall be maintained.
