Question 1

A driver is securing a 20,000 kg piece of machinery on a flatbed trailer. According to National Safety Code (NSC) Standard 10, what must be the minimum aggregate working load limit (WLL) of all tiedowns used?

Accepted Answer

10,000 kg

Answer

NSC Standard 10 requires that the sum of the working load limits of all securement devices, known as the aggregate WLL, must be at least 50% of the weight of the cargo being secured. Therefore, for a 20,000 kg piece of machinery, the minimum aggregate WLL is 10,000 kg.

Answer

NSC Standard 10 specifies two tiedowns for articles over 1.52 meters (5 feet) up to 3.04 meters (10 feet) in length. For articles longer than 3.04 meters, it requires two tiedowns for the first 3.04 meters plus one additional tiedown for each subsequent 3.04 meters or portion thereof.
