Or. Admin. Code § 734-074-0008 - Definitions
As used in Division 74 rules:
(1) "Auxiliary axle" is an axle that
qualifies as a booster axle, flip axle or lift axle and when attached to the
rear of a trailer shall be included in the measurement of the
trailer.
(2) "Booster Axles(s)"
means a separate vehicle bolted or pinned to another vehicle that redistributes
weight from one or more axles to other axles and pivots from side to side at
the connection point or has wheels that steer during turning.
(3) "CCD" means the Commerce and Compliance
Division of the Oregon Department of Transportation.
(4) "Converter dolly" means those devices
towed behind a vehicle and used to convert a semitrailer to function as a
self-supporting trailer.
(5)
"Dromedary truck-tractor" means a motor truck designed to carry a load and also
pull a semitrailer by using a kingpin to fifth wheel connection. Unless
specifically authorized, a dromedary truck-tractor may not tow a stinger
steered trailer.
(6) "Flip axle"
means an axle that is bolted or pinned to a vehicle and flips from the closed
position on the trailer to a deployed position on the ground extending the
length and hauling capacity of the trailer.
(7) "Idle Reduction System" means an
auxiliary power unit or other device or technology that is used to reduce
long-duration idling by allowing the main drive engine or auxiliary
refrigeration engine to be shut down.
(8) "Lift Axle" means an axle(s) that can be
raised from or lowered to the surface of the ground.
(9) "Motor Truck" means a motor vehicle that
is primarily designed or used for carrying loads other than
passengers.
(10) "New generation
wide base single tire" means a tire that has a nominal section width over 14
inches and a ratio of width to height less than or equal to 55.
(11) "Reasonably uniform in length" as used
in ORS 818.210, means a variance of not
more than eight feet from the longest to shortest self-supporting trailers or
semitrailers within the authorized combination of vehicles. It does not include
the length of a converter dolly when used to convert a semitrailer to a
self-supporting trailer.
(12)
"Tandem drive axles" means two or more axles spaced more than 40 inches but not
more than 96 inches apart, neither of which can be raised from the surface of
the ground, and where no one axle carries less than forty percent (40%) of the
tandem axle weight. Each axle of a tandem drive axle shall have four tires or
each axle may have two tires if tire width is at least 15 inches and each axle
transmits motive power to the road surface. Any weight controls for the tandem
axles on a power unit must be designed, installed and used such that the axles
always distribute the load so no axle, tandem axle or group of axles exceeds
the legal weight limits or bridge formula limits. All axle assemblies of the
tandem drive axles (including axles, tires, brakes) must be adequate to carry
the weight loading but may not have less than a 20,000 pound rating for each
axle.
(13) "Truck-Tractor" means a
motor vehicle designed and used primarily for drawing (towing) other vehicles
and constructed so as not to carry any load other than a part of the weight of
the vehicle or load, or both, as drawn.
(14) "Variable-load suspension axle" means an
axle that can vary the amount of weight being transmitted to the surface of the
road by adjustments made by the driver. Examples of adjustments available to
the driver include, but are not limited to, the use of tool(s), lock and key,
pressure regulators with handles or knobs. The term variable load suspension
axle does not include use of devices such as height control valves, axles
controlled by devices that raise the axle when the vehicle moves backward or
pre-set pressure regulators which are not adjustable by the driver.
