WAC 296-54-58950
Log trucks -- Wrappers and binders. (1)
On log trucks equipped with stakes, the following requirements
must apply:
(a) In the hauling of a one log load, one wrapper chain
or cable must be required and secured to the rear bunk. The
log must be properly blocked or secured in a manner which will
prevent it from rolling or shifting. An additional wrapper
secured to the front bunk is optional.
(b) In the hauling of two log loads, not less than two
wrapper chains or cables must be used to secure the load. The
logs must be properly blocked to prevent them from rolling or
shifting.
(c) On loads consisting of three or four logs not over
forty-four feet in length, the load must be secured by not
less than two properly spaced wrapper chains or cables. Ends
of short logs not secured by such wrappers must be secured
with extra wrappers. If any log is over forty-four feet in
length, the load must be secured by not less than three
properly spaced wrappers.
(d) Loads consisting of five or more logs, when the logs
are all seventeen feet or less in length, must be secured by
not less than two properly spaced wrappers. Loads consisting
of five or more logs, when any log is over seventeen feet in
length, must be secured by not less than three properly spaced
wrappers.
(2) On log trucks equipped with chock blocks the
following requirements must apply:
(a) In the hauling of a one log load, one wrapper chain
or cable shall be required and secured to the rear bunk and
the log must be properly blocked in a manner to prevent it
from rolling or shifting.
(b) One additional wrapper chain or cable shall be
required on log trucks using chock blocks over and above the
requirements in subsection (1)(c) and (d) of this section.
(3) In the case of short logs loaded crosswise, the
following method of securing the load must be used if the
truck or trailer is not provided with solid ends of a height
sufficient to prevent any log in the load from rolling off:
Not less than two chock blocks must be used at each open
end of the vehicle and the load must be held with at least two
wrapper chains or cables. The wrappers must be firmly
attached to the end of the truck or trailer. Rigid standards
or stakes may be used in lieu of chock blocks but each such
standard or stake must be either rigidly connected to the bed
of the truck or trailer or must be placed in a tight-fitting
socket at least 12 inches in depth. Other means furnishing
equivalent security may be acceptable.
(4) When two wrappers are required, they must be applied
within six feet of the front and rear bunks. When more than
two wrappers are required, the front and back binder must be
applied within six feet of the front and rear bunks.
(5) To properly secure short logs, binders must be placed
near the end, not less than twelve inches from the end of the
log.
(6) Log(s) loaded on top or in outside saddles of a load
must not be transported unless secured by at least two wrapper
chains or cables, one of which must be placed near each end of
such log.
(7) All wrappers and binders must be fastened in place
prior to tightening to prevent the displacement of logs on the
top of the load.
(8) All wrapper chains or cables, except in the case of
one log load, must entirely surround the load. This does not
apply to gut-wrappers.
(9) Gut-wrappers, when used, must be adjusted so as to be
tightened by, but not carry the weight of the logs above them.
(10) A warning must be given before throwing wrappers
over the load and care must be taken to avoid striking other
persons with the wrapper.
(11) Each log not contained within the stakes must be
secured with at least two wrappers before the truck leaves the
vicinity of the landing/loading area.
(12) While moving logs, poles, or log chunks within
sorting or mill yards, that could roll or slide off the truck
due to snow or ice conditions, or the logs or log chunks do
not extend beyond the stakes, at least two wrappers and
binders must be used regardless of the height of the load.
(13) Wrapper chains or cables, binders, fasteners, or
attachments thereof, used for any purpose as required by these
standards must have a minimum breaking strength of not less
than fifteen thousand pounds and must be rigged so that it can
be safely released.
| Note: |
3/8-inch hi-test steel chain, 7/16-inch improved plow steel wire rope of 6 x 19 or 6 x 37 construction, or materials having
equivalent strength, when in compliance with the requirements herein contained, will be acceptable. (The diameter of the wire
rope is immaterial as long as it meets the minimum breaking strength requirements.) |
| Note: |
Nylon straps and ratchet binders having an equivalent breaking strength may be used when securing loads on (hay rack) log
hauling systems. |
(14) A loaded logging truck required to have wrappers by
this section, may be moved within the loading area without
wrappers only if such movement does not present a hazard to
workers.
(15) For the purposes of this standard, applied bundle
straps or banding are not acceptable as wrappers and binders.
(16) All loose ends of wrapper chains or cables must be
securely fastened so as to prevent their swinging free in a
manner that will create a hazard.
(17) Binders for securing wrappers on logging trucks must
be fitted with hooks of proper size and design for the wrapper
chain being used.
(18) Wrappers must be removed from service when any of
the following conditions exist:
(a) Excessively worn links on chains;
(b) Deformed or stretched chain links;
(c) Cracked chain links; or
(d) Frayed, stranded, knotted, or otherwise defective
wire rope.
(19) Pipe extension handles (swedes) for tightening or
securing binders must be no longer than thirty-six inches. Care must be taken that a sufficient amount of the pipe
extends over the binder handle.
(20) Defective binders must be immediately removed from
service.
