355 IAC 3-5-3 Mounting containers on truck

Sec. 3. (a) The means of attachment of any container to the cradle, frame, or chassis of a vehicle shall be designed to withstand static loading in any direction equal to twice the weight of the container and attachments when filled with lading using a safety factor of not less than 4, based on the ultimate strength of the material to be used. (b) Hold-down devices, when used, shall anchor the container to the cradle, frame, or chassis in a suitable and safe manner that will not introduce undue concentration of stresses. These devices shall incorporate positive means for drawing the container down tight, and suitable stops or anchors shall be provided to prevent relative movement between container and framing due to stopping, starting, or changes in direction. (c) Whenever any vehicle is designed and constructed so that cargo tanks constitute in whole or in part the stress member used in lieu of a frame, such cargo tanks shall be designed to withstand the stresses thereby imposed in addition to those covered by the code under which the cargo tank was designed. (d) If a liquid withdrawal line is installed in the bottom of a container, the connections thereto, including the hose, shall not be lower than the lowest horizontal edge of the trailer axle. (e) Provisions shall be made to secure both ends of the hose while in transit. (f) When the cradle and the container are not welded together, suitable material shall be used between them to reduce abrasion.
