Universal Citation: MT Admin Rules 4.12.734
Current through Register Vol. 18, September 20, 2024
(1) ARM 4.12.725 applies to this section.
(2) Mounting containers in trucks:
(a) Stops (wood or metal blocks) shall
be mounted on the truck, semi-trailer, trailer, or on the container in such a
way that the container shall not be dislodged from its mounting due to the
vehicle coming to a sudden stop. Back slippage shall also be
prevented.
(b) Hold-down devices
shall anchor the container to the cradle, frame, or chassis in a manner to
prevent the container from rolling or bouncing off the vehicle and that will
not create undue concentration of stress.
(c) Any truck or trailer designed so that the
container or containers constitute in whole or part the stress member of the
chassis of the vehicle in lieu of a frame shall be constructed to withstand the
additional stresses which are imposed. Cradles, when welded, shall be welded to
the container by a welder who is registered under the code and shall be
designed to withstand a force in any direction equal to two (2) times the
weight of the container when filled with nitrogen fertilizer
solution.
(d) If a liquid
withdrawal line is installed in the bottom of a container, the connections
thereto, including hose, shall not be lower than the lowest horizontal edge of
the trailer axle.
(e) Both ends of
the hose shall be secured while in transit.
(f) When the cradle and the tank are not
welded together, material which will not deteriorate with weather or create a
friction shall be used between them to eliminate metal-to-metal
friction.
