绑带数量和工作载荷限值（WLL）各有要求Meet both the tiedown count and the WLL requirement
- 具体要求What the rule requires
- 对没有有效阻挡前移的一般件货：长不超过 5 英尺且重不超过 1,100 磅至少一条；同样长度但更重，或长超过 5 英尺至 10 英尺，至少两条；超过 10 英尺时前 10 英尺两条，之后每增加 10 英尺或不足 10 英尺再加一条。有效阻挡前移时一般每 10 英尺或不足 10 英尺至少一条。For general articles not effectively blocked against forward movement: at least one tiedown if no longer than five feet and no heavier than 1,100 pounds; at least two if heavier at that length or longer than five but no longer than ten feet. Above ten feet, use two for the first ten feet plus one for each additional ten feet or fraction. With effective forward blocking, generally use at least one per ten feet or fraction.
- 条件与例外Conditions and exceptions
- 专门货物和特殊形状的大型机械另有规定。绑带数量达标后，仍须满足总 WLL 及其他固定要求。Commodity-specific and special-purpose large machinery rules may differ. Meeting the minimum count alone does not establish adequate WLL or full securement compliance.
(a) (a) When tiedowns are used as part of a cargo securement system, the minimum number of tiedowns required to secure an article or group of articles against movement depends on the length of the article(s) being secured, and the requirements of paragraphs (b) and (c) of this section. These requirements are in addition to the rules under § 393.106.
(b) (b) When an article is not blocked or positioned to prevent movement in the forward direction by a headerboard, bulkhead, other cargo that is positioned to prevent movement, or other appropriate blocking devices, it must be secured by at least:
(b)(1) (1) One tiedown for articles 5 feet (1.52 meters) or less in length, and 1,100 pounds (500 kg) or less in weight;
(b)(2) (2) Two tiedowns if the article is:
(b)(2)(i) (i) 5 feet (1.52 meters) or less in length and more than 1,100 pounds (500 kg) in weight; or
(b)(2)(ii) (ii) Longer than 5 feet (1.52 meters) but less than or equal to 10 feet (3.04 meters) in length, irrespective of the weight.
(b)(3) (3) Two tiedowns if the article is longer than 10 feet (3.04 meters), and one additional tiedown for every 10 feet (3.04 meters) of article length, or fraction thereof, beyond the first 10 feet (3.04 meters) of length.
(c) (c) If an individual article is blocked, braced, or immobilized to prevent movement in the forward direction by a headerboard, bulkhead, other articles which are adequately secured or by an appropriate blocking or immobilization method, it must be secured by at least one tiedown for every 3.04 meters (10 feet) of article length, or fraction thereof.
(d) (d) Special rule for special purpose vehicles. The rules in this section do not apply to a vehicle transporting one or more articles of cargo such as, but not limited to, machinery or fabricated structural items (e.g., steel or concrete beams, crane booms, girders, and trusses, etc.) which, because of their design, size, shape, or weight, must be fastened by special methods. However, any article of cargo carried on that vehicle must be securely and adequately fastened to the vehicle.
