(a) Motor logging, trucks and trailers shall be equipped with bunks, stakes, chock blocks, or similar devices. Such blocks, stakes, or other devices shall extend no less than 8 inches above the top edge of the bunk.
EXCEPTION: When hauling a single log, chock blocks may be turned in, provided that these blocks extend at least 5 1/2 inches above the top of the bunk.
(b) Chocks and stakes shall be arranged so that they can be released from the side opposite the log-dumping side. They shall not be locked in any manner which makes it necessary to hammer on chains for releasing. Molly Hogans and cold shuts shall not be permitted in chains. Chock and stake chains shall be at least 1/2-inch high-test material or its equivalent. Chocks shall not project beyond the end of the bunk.
(c) Chocks and stakes shall be of steel, or material of equivalent bending and compression strength, and maintained in good condition.
(d) Bunks bent down more than 1-inch on either end shall be straightened and strengthened.
(e) Sufficient clearance shall be maintained to prevent bunk binding. Bunks shall pivot freely, and be cleaned and greased when necessary. Kingpins shall be maintained to minimum tolerances.
(f) To minimize end shift, the top edge of the bunks shall be no more than 3/8-inch thick and either square or beveled to a sharp edge.
(g) Bunk locks or centering devices shall be installed on all trucks and trailers, and bunk locks shall be disengaged before moving the loaded truck.
(h) When trailed, truck and trailer combinations shall be connected with a safety strap or chain which shall be of sufficient strength to control the trailer in event of failure of the regular trailer hitch or coupling. Straps of 1/2-inch plow steel or chains of 1/2-inch, high-test steel, with equivalent fittings, are considered adequate. Fittings shall be designed so that they cannot become accidentally unhooked.
