§ 183.4. Basic protection components.
(a) Metal in coils. A vehicle or combination carrying metal cargo of the type specified in § 183.1(1) (relating to application) shall be equipped with devices providing protection against shifting or falling cargo that meet the following requirements:
(1) Coils with eye vertical. Requirements for securing coils with eye vertical shall be as follows:
(i) Except as provided in paragraph (3)(ii) and (iii), a coil loaded with its eye vertical shall be secured as follows: one chain against the coil restricting it against forward motion, one chain against the coil restricting it against rearward motion and one chain over the top of the coil restricting it against vertical motion. The same length of chain may not be used to perform more than one of the above functions. The configuration of chains shall be arranged to effectively restrain side-to-side motion.
(ii) If two or more coils with their eyes vertical are grouped and loaded in a transverse row or rows, they shall be secured by: a chain against the front of the group restricting it against forward motion, a chain against the rear of the group restricting it against rearward motion and one chain over the top of each transverse row restricting vertical motion. The configuration of chains shall be arranged to effectively restrain side-to-side motion.
(iii) If two or more coils with their eyes vertical are grouped in a fore-and-aft direction, they shall be secured by: a chain against the front of the group restricting it against forward motion, a chain against the rear of the group restricting it against rearward motion and a chain over the top of each coil restricting it against vertical motion. The configuration of chains shall be arranged to effectively restrain side-to-side motion.
(2) Coils with eye crosswise. A coil loaded with its eye crosswise shall be secured by: a chain through the eye restricting it against forward motion, a chain through the eye restricting it against rearward motion and timbers of at least nominal 4 by 4 inch cross-section and a length at least 75% of the width of the coil, tightly placed against the front and back of the coil and restrained as to restrict fore-and-aft motion.
(i) If two or more coils are loaded against each other, in the fore-and-aft direction, then only the foremost and rearmost coils need be secured as to prevent relative motion between the coils and the vehicle.
(ii) If more than one coil is loaded against another, a coil shall be secured by at least one chain so positioned as to restrict it against forward motion, except that the chain for the rearmost coil shall restrain it against rearward motion. The configuration of chains shall be arranged to effectively restrain side-to-side motion.
(iii) If two or more coils of approximately the same outside diameter are loaded side-by-side in a transverse row, then each row shall be secured by a chain through their eyes restricting them against forward motion, a chain through their eyes restricting them against rearward motion and timbers of at least nominal 4 by 4 inch cross-section and a length at least 75% of the width of the coil, tightly placed against the front and back of the coils and restrained as to restrict fore-and-aft motion. The configuration of chains shall be arranged to effectively restrain side-to-side motion.
(3) Coils with eye lengthwise. Requirements for securing coils with eye lengthwise shall be as follows:
(i) Except as provided in subparagraphs (ii) and (iii), each coil loaded with its eye lengthwise shall be secured by a chain over the top of the coil or two chains through the eye of the coil restricting it against side-to-side motion, and timbers of at least nominal 4 by 4 inch cross-section tightly placed against the sides of the coil and restrained so as to restrict side-to-side motion. If only one chain is used over the top of the coil, timbers of at least nominal 2 by 4 inch cross-section shall be tightly placed against the front and back of the coil and firmly secured to the longitudinal blocking required above so as to restrict any fore-and-aft motion. The configuration of chains shall be arranged to effectively restrain vertical and fore-and-aft motion.
(ii) Two coils of approximately equal outside diameter may be loaded side-by-side if they are secured by a chain through the eye of each coil crossed so as to restrict the coils against side-to-side motion or one chain over the top of both coils; and timbers of at least nominal 4 by 4 inch cross-section tightly placed against the outer side of each of the coils. If only one chain is used over the top of both coils, timbers of at least nominal 2 by 4 inch cross-section shall be tightly placed against the front and back of the coils and firmly secured to the longitudinal blocking required above so as to effectively restrain vertical and fore-and-aft motion.
(iii) If two or more coils are loaded end-to-end in a single longitudinal row or two longitudinal side-by-side rows, of approximately equal outside diameter, they shall be secured by a chain over the top of each coil and transverse row of two coils, by two chains through the eyes of a single lengthwise row or by a chain through the eyes of a row of a side-by-side group, crossed so as to restrain side-to-side motion; and timbers of at least nominal 4 by 4 inch cross-section tightly placed against a side of a single row or the outer sides of a double row and restrained so as to restrict side-to-side motion. If only one chain is used over the top of a coil in a single row or transverse row of two coils in a side-by-side group, timbers of at least nominal 2 by 4 inch cross-section shall be tightly placed against the front and back of the row and firmly secured to the longitudinal blocking required above so as to restrict fore-and-aft motion. The configuration of chains shall be arranged to effectively restrain vertical and fore-and-aft motion.
(b) Metal in ingots and pipes. A vehicle or combination carrying metal cargo of the type specified in § 183.1(2) shall be equipped with devices providing protection against shifting or falling cargo that meet the following requirements:
(1) An article or group of articles shall be secured by at least chain or cable over its top for at least each 8 feet of length with no less than two chains on an individual article or combination of articles banded or otherwise secured together and handled as a single unit.
(i) A combination of articles loaded side-by-side across the width of a vehicle shall be considered as a single unit.
(ii) Articles 8 feet or less in length may be mounted in the fore-and-aft direction if they are securely abutted one end to another, and are secured in place by metal angles or if a timber of at least nominal 4 by 4 inch cross-section is placed longitudinally over the articles and the metal angles or timbers are secured by a chain.
(iii) No additional securing devices shall be required for tiered articles than for a single level of articles if a tiered article rests securely on the article on which it is placed.
(2) On pole trailers, there shall be at least two binder chains or cables to secure the load to the forward bolster and two binder chains or cables to secure it to the rear bolster.
(c) Logs. Requirements for securing logs shall be as follows:
(1) A load of logs, consisting of one or more stacks of logs, carried on or by a vehicle or combination shall be secured by at least three binders, chains or straps.
(i) A stack of logs containing logs longer than 3 feet carried on or by a vehicle or combination shall be secured by at least three binders, chains or straps.
(ii) A stack of logs not longer than 3 feet carried on or by a vehicle or combination, with one or more additional stacks of logs, shall be secured by at least two binders, chains or straps.
(2) On open-body or stake-body vehicles, there shall be a sufficient number of vertical bars, posts or stakes, at least two on each side, to secure each stack of logs in the event of failure of the binders, chains or straps.
(3) This subsection does not apply to logs carried in a pick-up truck, dump truck or similar vehicle having solid sides and rear, if the logs are not loaded above the sides and rear.
(d) Special restraining devices. If a vehicle is constructed with a depression in the floor or other restraining devices affixed thereto, and they perform the functions required above for various types of timber, then such timbers may not be required.
